Why GAO Did This Study: 

Basel II, the new risk-based capital framework based on an 
international accord, is being adopted by individual countries. It 
includes standardized and advanced approaches to estimating capital 
requirements. In the United States, bank regulators have finalized an 
advanced approaches rule that will be required for some of the largest, 
most internationally active banks (core banks) and proposed an optional 
standardized approach rule for non-core banks that will also have the 
option to remain on existing capital rules. In light of possible 
competitive effects of the capital rules, GAO was asked to examine (1) 
the markets in which banks compete, (2) how new capital rules address 
U.S. banks’ competitive concerns, and (3) actions regulators are taking 
to address competitive and other potential negative effects during 
implementation. Among other things, GAO analyzed data on bank products 
and services and the final and proposed capital rules; interviewed U.S. 
and foreign bank regulators, officials from U.S. and foreign banks; and 
computed capital requirements under varying capital rules. 

What GAO Found: 

Large and internationally active U.S.-based banks (core banks) that 
will adopt the Basel II advanced approaches compete among themselves 
and in some markets with U.S.-based non-core banks, investment firms, 
and foreign-based banks. Non-core banks compete with core banks in 
retail markets, but in wholesale markets core banks often compete with 
investment firms and foreign-based banks. Because holding capital is 
costly for banks, differences in regulatory capital requirements could 
influence costs, prices, and profitability for banks competing under 
different capital requirements. 

The new U.S. capital rules addressed some earlier competitive concerns 
of banks; however, other concerns remain. By better aligning the 
advanced approaches rule with the international accord and proposing an 
optional standardized approach rule, U.S. regulators reduced some 
competitive concerns for both core and non-core banks. For example, the 
U.S. wholesale definition of default for the advanced approaches is now 
similar to the accord’s. Core banks continue to be concerned about the 
leverage requirement (a simple capital to assets calculation), which 
they believe places them at a competitive disadvantage relative to 
firms not subject to a similar requirement. Foreign regulators have 
been working with U.S. regulators to coordinate Basel II implementation 
for U.S. banks with foreign operations. The proposed standardized 
approach addresses some concerns non-core banks raised by providing a 
more risk sensitive approach to calculating regulatory requirements. 
But other factors likely will reduce differences in capital for banks 
competing in the United States; for example, the leverage requirement 
establishes a floor that may exceed the capital required under the 
advanced and standardized approaches. 

Many factors have affected the pace of Basel II implementation in the 
United States and, while the gradual implementation is allowing 
regulators to consider changes in the rules and reassess banks’ risk-
management systems, regulators have not yet taken action to address 
areas of uncertainty that could have competitive implications. For 
example, the final rule provides regulators with considerable 
flexibility and leaves open questions such as which banks may be 
exempted from the advanced approaches. Although the rule provides that 
core banks can apply for exemptions and regulators should consider 
these in light of some broad categories, such as asset size or 
portfolio mix, the rule does not further define the criteria for 
exemptions. Some industry participants we spoke with said that 
uncertainties about the implementation of the advanced approaches have 
been a problem for them. Moreover, regulators have not fully developed 
plans for a required study of the impacts of Basel II before full 
implementation. Lack of specificity in criteria, scope, methodology, 
and timing will affect the quality and extent of information that 
regulators will have to help assess competitive and other impacts, 
determine whether there are any material deficiencies requiring future 
changes in the rules, and determine whether to permit core banks to 
fully implement Basel II. 

What GAO Recommends: 

GAO recommends that the U.S. bank regulators (1) clarify how they will 
use regulatory flexibility built into the rules and (2) fully develop 
plans, on a joint basis, for the required study of the impacts of Basel 
II. The bank regulators generally agreed with our recommendations in a 
joint response to this report.

Ensuring that banks maintain adequate capital is essential to the 
safety and soundness of the banking system.[Footnote 1] Basel II, the 
newly revised risk-based capital framework, aims to better align 
minimum capital requirements with enhanced risk-measurement techniques 
and to encourage banks to develop a more disciplined approach to risk 
management. Basel II rests on an international accord (the New Basel 
Accord) adopted by the Basel Committee on Banking Supervision (Basel 
Committee) in June 2004.[Footnote 2] The New Basel Accord includes a 
standardized approach and advanced approaches, more complex approaches 
that large, internationally active banks are encouraged to use. U.S. 
federal banking regulators have been working to finalize capital rules 
based on this accord. Since our February 2007 report on Basel II, U.S. 
federal banking regulators have finalized the advanced approaches rules 
that are required for some of the largest and most internationally 
active banking organizations (core banks), which account for about half 
of U.S. banking assets.[Footnote 3] Some other banks may choose to 
comply with the advanced approaches rule as well. These rules lay out a 
phased implementation schedule, which generally requires core banks to 
have Basel II implementation plans approved by their boards of 
directors by October 1, 2008. In addition, in July 2008, U.S. banking 
regulators published for comment a proposed rule on the standardized 
approach, a simpler version of the new regulatory capital framework 
that could be adopted by banks that were not required to adopt the 
advanced approaches (non-core banks). 

Though the goal of Basel II was to improve the safety and soundness of 
the banking system through better risk management and create a level 
playing field for internationally active banks, the development of 
Basel II has generated concerns among banks, banking regulators, and 
other interested parties that potentially different capital 
requirements and implementation costs for various categories of U.S. 
and foreign banks could have competitive effects.[Footnote 4] These 
concerns arose, in part, because U.S. banks that all have been 
operating under the same risk-based capital rules--known as Basel I-- 
may be operating under different capital rules in the future--Basel II 
advanced approaches, Basel II standardized approach, or Basel I. In 
addition, because the New Basel Accord identified certain areas for 
national discretion, the capital regimes being adopted in various 
countries differ from that being implemented in the United States. 

The risk-management systems for financial institutions and the 
information systems on which they rest have been called into question 
by the failure of some of these systems during the market turbulence 
that began with subprime mortgages in 2007. While this turmoil is not 
the focus of this report, it is an important factor that is leading 
banking organizations and their regulators to reassess capital 
requirements and other aspects of bank regulation and 
supervision.[Footnote 5] These assessments could lead to changes in the 
Basel II rules or could influence the implementation of those rules in 
the United States. In addition, as a result of concerns about the 
ability of U.S. financial institutions to compete with institutions 
based in foreign countries, the U.S. Department of the Treasury has 
proposed a restructuring of the complex U.S. regulatory 
system.[Footnote 6] Various congressional committees have held hearings 
that addressed this issue and in the past, we have recommended that the 
U.S. regulatory system be restructured.[Footnote 7] 

In light of concerns about possible competitive effects, you requested 
that we review the competitive implications of Basel II for non-core 
U.S. banks in comparison to core banks adopting the advanced approaches 
and how differences in the implementation of Basel II in foreign 
countries might affect the competitiveness of internationally active 
banks operating in the United States. Specifically, this report 
examines (1) the nature of the competitive environment in which U.S. 
banking organizations operate, (2) the extent to which the new capital 
rules address competitive concerns of U.S. banking organizations 
internationally and domestically, and (3) actions regulators are taking 
to address competitive and other potential negative effects of the new 
capital rules during implementation. 

To meet our objectives, we reviewed the New Basel Accord, the U.S. 
proposed rules on the advanced approaches and standardized approach, 
the U.S. final advanced approaches rule, supervisory guidance, and 
related materials. In addition, we reviewed research related to the 
impact of Basel II in the United States and the European Union. We 
interviewed officials at the federal bank regulatory agencies 
responsible for implementing Basel II, including examination and policy 
staff. We also interviewed officials from all of the core banks and 
other domestic and foreign banks with operations in the United States. 
In addition, we interviewed officials from several foreign bank 
regulatory agencies; domestic and foreign trade associations; credit 
rating agencies; and several academics and consultants with banking 
expertise. To describe the competitive environment in which U.S. 
banking organizations operate, we analyzed various data sources on the 
products and services that U.S. and foreign banking organizations offer 
domestically and internationally. To assess the competitive impact of 
the different capital rules on U.S. banks, we computed capital 
requirements for certain products under the varying rules and reviewed 
academic and other studies of the impact of regulatory capital on bank 
behavior. 

We conducted this performance audit from May 2007 to September 2008 in 
accordance with generally accepted government auditing standards. Those 
standards require that we plan and perform the audit to obtain 
sufficient, appropriate evidence to provide a reasonable basis for our 
findings and conclusions based on our audit objectives. We believe that 
the evidence obtained provides a reasonable basis for our findings and 
conclusions based on our audit objectives. Appendix I discusses our 
scope and methodology in further detail. 

Results in Brief: 

Core banks--large and internationally active U.S. banks that will be 
required to adopt the advanced approaches for Basel II--compete with 
other core banks and in some markets with non-core U.S.-based banks, 
other financial institutions, and foreign-based banks. Core banks that 
will adopt the advanced approaches have varying business models such 
that some focus on domestic retail banking activities such as 
residential mortgages, some focus on wholesale activities such as 
lending to large corporate clients domestically and abroad, and others 
are engaged in the full range of these activities. In retail markets 
such as those for residential mortgages, core banks often compete with 
smaller non-core banks that are not likely to adopt the advanced 
approaches. In wholesale markets, core banks often compete with 
investment firms. Core banks compete globally with investment firms and 
also with foreign-based banks. In addition, banks that are subsidiaries 
or branches of foreign-based banks are active in U.S. markets at both 
the retail and wholesale levels. While Basel II likely will apply to 
foreign-based banks in their home countries, the specifics of the rules 
and their implementation in other countries will differ from those in 
the United States, in part, because the New Basel Accord identified a 
number of areas for national discretion. Because holding capital is 
costly for banks, differences in regulatory capital requirements could 
influence costs, prices, and profitability for banks competing under 
different capital requirements. 

U.S. regulators addressed some of the banking industry's competitive 
concerns with the advanced approaches rule for core banks and the 
proposal of an optional standardized approach rule for other banks. 
However, some of the industry's competitive concerns about the U.S. 
capital framework remain. In developing the rules, regulators analyzed 
some competitive issues raised by banks. By adopting a final advanced 
approaches rule that is closer to the New Basel Accord, U.S. regulators 
reduced the differences between the U.S. rule as originally proposed 
and the New Basel Accord that had the potential to lead to greater 
implementation costs. For example, in the final advanced approaches 
rule banks will use a single wholesale definition of default for both 
their U.S. and foreign operations, thus reducing the cost of operating 
in multiple countries. Nonetheless, core banks are concerned about 
continuing to be subject to the leverage requirement, which they 
believe could place them at a competitive disadvantage relative to 
certain foreign-based banks and investment firms, which do not have a 
similar requirement. In efforts to mitigate other differences, U.S. 
regulators have been working with foreign regulators, bilaterally and 
as members of international bodies, to coordinate Basel II 
implementation for U.S.-based internationally active banks. The 
proposed standardized approach rule issued by U.S. regulators in July 
2008 addresses some concerns raised by non-core banks--those banks not 
required to adopt the advanced approaches. These banks were concerned 
that core banks would have a competitive advantage because they would 
be able to hold less capital for some assets. The proposed standardized 
approach would allow for additional risk-sensitivity-over Basel I with 
respect to the capital treatment for certain assets, including 
residential mortgages. Among other factors, the leverage requirement 
may reduce differences in capital among banks competing in the United 
States because it establishes a floor that may exceed capital required 
under the advanced or standardized approaches for certain low-risk 
assets. 

Since we last reported on Basel II in February 2007, the regulators 
have made significant progress by jointly issuing the advanced 
approaches rule and a proposed rule for an optional standardized 
approach. However, while the gradual implementation is allowing 
regulators to consider changes in the rules and reassess banks' risk 
management systems, regulators have not taken action to address some 
areas of uncertainty that could have competitive implications or other 
negative effects. For example, the regulatory flexibility that the 
advanced approaches rule provides will help regulators deal with the 
rule's unforeseen consequences, but leaves uncertainties such as which 
banks will ultimately be exempted from using the advanced approaches. 
While the regulators have stated that they may exempt some core banks 
from using the advanced approaches, they have only provided broad 
categories such as asset size and portfolio mix rather than specific 
criteria for making these decisions. And, in the proposed standardized 
approach rule, regulators have asked for comments on the question of 
whether large and internationally active core banks should be able to 
use the proposed standardized approach. These uncertainties may 
continue to reflect the difficulties that resulted from the differing 
perspectives the regulators brought to negotiations during the 
development of Basel II. In addition, some industry participants we 
spoke with said that uncertainty about the implementation of the 
advanced approaches rule has been a problem for them. Finally, 
regulators have undertaken some planning for a study of the impact of 
the advanced approaches, but plans are not fully developed. The 
advanced approaches rule called for a study of the rule's impact to 
determine whether major changes in the rule needed to be made before 
banks would be permitted to fully implement the new rule. However, the 
regulators have not developed criteria by which to assess Basel II, 
have not specified whether the scope of the study will go beyond core 
banks to consider, for example, investment firms, or developed a 
methodology to analyze opportunities for regulatory arbitrage. Lack of 
development or specificity in criteria, scope, methodologies, and 
timing will affect the quality and extent of information that 
regulators will use to help assess competitive and other impacts, 
determine whether there are any material deficiencies that require 
changes in the rules, and determine whether core banks should fully 
implement Basel II. 

To further limit any potential negative effects and to reduce the 
uncertainty about Basel II implementation, we are making two 
recommendations to the heads of the Federal Deposit Insurance 
Corporation (FDIC), Board of Governors of the Federal Reserve System 
(Federal Reserve), Office of the Comptroller of the Currency (OCC), and 
Office of Thrift Supervision (OTS). Specifically, where possible, these 
regulators should reduce the uncertainty built into the Basel II rules 
by better clarifying the use of certain regulatory flexibilities, 
particularly with regard to how they will exercise exemptions from the 
advanced approaches requirements and the extent to which core banks 
will be allowed to adopt the standardized approach. In addition, to 
improve understanding of potential competitive effects, we recommend 
that the regulators fully develop plans, on a joint basis, for the 
required study of the impacts of Basel II. 

We requested comment on a draft of this report from the heads of the 
Federal Reserve, FDIC, OCC, OTS, Securities and Exchange Commission 
(SEC), and Department of the Treasury. We received written comments 
from the Federal Reserve, FDIC, OCC, and OTS, who provided a joint 
letter, which is reprinted in appendix IV. In their joint letter, the 
banking regulators said that they were in general agreement with our 
recommendations. Specifically, the regulators said that they will work 
together to resolve, at the earliest possible time, the question posed 
for comment in the proposed standardized approach rule regarding 
whether and to what extent core banks should be able to use the 
standardized approach. With regard to clarifying certain regulatory 
flexibilities, the regulators said they will continue to make decisions 
concerning the exemption of core banks from the advanced approaches 
based on the specifics of a bank's request; they have already commenced 
discussions to ensure a clear and consistent interpretation of these 
provisions is conveyed to U.S. banks. In addition, regarding the need 
to jointly plan the required study, the regulators said that they will 
begin to prepare more formal plans for the study once they have a 
firmer picture of banks implementation plans. The banking regulators 
also provided technical comments, which we incorporated in the report 
where appropriate. We did not receive comments from SEC or the 
Department of the Treasury. 

Background: 

Basel II rests on the New Basel Accord, which established a more risk- 
sensitive regulatory framework that was intended to be sufficiently 
consistent internationally but that also took into account individual 
countries' existing regulatory and accounting systems. The U.S. bank 
regulators have been adapting the New Basel Accord for use by U.S. 
banks. 

The New Basel Accord: 

The New Basel Accord sets forth minimum requirements, which regulators 
may complement with additional capital requirements, such as a leverage 
ratio. The New Basel Accord also identifies a number of areas for 
national discretion, thus requiring regulators from different countries 
to work together to understand how each country is implementing the New 
Basel Accord and to ensure broad consistency in the application of the 
regulatory framework across jurisdictions. The New Basel Accord 
consists of three pillars: (1) minimum capital requirements, (2) 
supervisory review of an institution's internal assessment process and 
capital adequacy, and (3) effective use of disclosure to strengthen 
market discipline as a complement to supervisory efforts.[Footnote 8] 
As shown in figure 1, Pillar 1 establishes several approaches (of 
increasing complexity) to measuring credit and operational 
risks.[Footnote 9] The advanced approach for credit risk (also known as 
the advanced internal ratings-based approach) uses risk parameters 
determined by a bank's internal systems as inputs into a formula 
developed by supervisors for calculating minimum regulatory capital. In 
addition, banks with significant trading assets--assets banks use to 
hedge risks or to speculate on price changes in markets for themselves 
or their customers--must calculate capital requirements for market risk 
under Pillar 1.[Footnote 10] Pillar 2 explicitly recognizes the role of 
supervisory review, which includes assessments of capital adequacy 
relative to a bank's overall risk profile and early supervisory 
intervention that are already part of U.S. regulatory practices. Pillar 
3 establishes disclosure requirements that aim to inform market 
participants about banks' capital adequacy in a consistent framework 
that enhances comparability. See appendix II for more information on 
the three pillars of the advanced approaches.

After extensive discussions and consultation that included issuing an 
advanced notice of proposed rulemaking in 2003 and a Notice of Proposed 
Rulemaking (NPR) in 2006, the U.S. banking regulators issued a final 
rule on the advanced approaches that became effective on April 1, 
2008.[Footnote 11] Under the rule, only certain banks--core banks--will 
be required to adopt the advanced approaches for credit and operational 
risk. Core banks are those with consolidated total assets (excluding 
assets held by an insurance underwriting subsidiary of a bank holding 
company) of $250 billion or more or with consolidated total on-balance 
sheet foreign exposure of $10 billion or more. Publicly available 
information shows that, as of July 2008, 12 banks met the rule's basic 
criteria for being a core bank. A depository institution also is a core 
bank if it is a subsidiary of another bank that uses the advanced 
approaches. Under the rule, a core bank's primary federal regulator may 
determine that application of the advanced approaches is not 
appropriate in light of a core bank's asset size, level of complexity, 
risk profile, or scope of operations. In addition, banks that are not 
required to adopt the advanced approaches, but meet certain 
qualifications, may voluntarily choose to comply with the advanced 
approaches. Generally, core banks had or will have from April 2008 
until April 2010 to begin the four phases that lead to the full 
implementation of Basel II.[Footnote 12] As a result, core banks could 
be ready for full implementation between April 2012 and April 2014. By 
January 1, 2008, banks in the European Union, Canada, and Japan had 
moved off of Basel I and begun implementing some version of the New 
Basel Accord's advanced approaches or standardized approach for all of 
their banks. Banks located in the European Union, Canada, and Japan 
expect to have fully implemented Basel II sometime in 2010. 

Non-core banks--those that do not meet the definition of a core bank-- 
will have the option of adopting the advanced approaches, a 
standardized approach when finalized, or remaining on Basel I. The 
proposed standardized approach rule, published in July 2008, provides 
for a more risk-sensitive approach than Basel I by classifying banks' 
assets into more risk categories and assessing different capital 
requirements according to the riskiness of the category.[Footnote 13] 
While Basel I has 5 risk categories, the proposed standardized approach 
rule includes 16 categories. In contrast to the advanced approaches, 
the standardized approach relies more on external risk assessments-- 
conducted by rating agencies--than on a bank's own assessments of a 
certain product's or borrower's risk. The proposed U.S. standardized 
approach generally is consistent with the standardized approach 
outlined in the New Basel Accord, but diverges from the New Basel 
Accord to incorporate more risk sensitive treatment, most notably in 
the approaches for residential mortgages and equities held by banks. 

Additional U.S. Capital Requirements: 

The U.S. regulatory capital framework also includes minimum leverage 
capital requirements. Banks, thrifts, and bank holding companies are 
subject to minimum leverage standards, measured as a ratio of Tier 1 
capital to total assets. The minimum leverage requirement is either 3 
or 4 percent, depending on the type of institution and a regulatory 
assessment of the strength of its management and controls.[Footnote 14] 
Leverage ratios are a commonly used financial measure of risk. Greater 
financial leverage, as measured by lower proportions of capital 
relative to assets, increases the riskiness of a firm, all other things 
being equal. If the leverage capital requirement is greater than the 
risk-based level required then the leverage requirement would be the 
binding overall minimum requirement on an institution. Depository 
institutions also are subject to the Federal Deposit Insurance 
Corporation Improvement Act of 1991, which created a new supervisory 
framework known as prompt corrective action (PCA) that links 
supervisory actions closely to these banks' capital ratios. PCA, which 
applies only to depository institutions and not bank holding companies, 
requires regulators to take increasingly stringent forms of corrective 
action against banks as their leverage and risk-based capital ratios 
decline.[Footnote 15] Under this rule, regulators also can require 
banks to hold more than minimum levels of capital to engage in certain 
activities. In addition, under the Bank Holding Company Act, the 
Federal Reserve can require that bank holding companies hold additional 
capital to engage in certain activities. 

U.S. Regulators Responsible for Implementing Basel II: 

In the United States, the four federal bank regulators oversee the 
implementation of Basel II for banks and SEC oversees the 
implementation of Basel capital rules for investment firms. The 
financial institutions that will be involved in the implementation of 
Basel II are organized as bank holding companies, thrift holding 
companies, or consolidated supervised entities (CSE). At a consolidated 
level the Federal Reserve supervises bank holding companies that are 
subject to Basel capital requirements, OTS supervises thrift holding 
companies that are not subject to Basel capital requirements, and SEC 
supervises CSEs that voluntarily choose to be subject to consolidated 
oversight including Basel capital reporting requirements.[Footnote 16] 
Each of these types of holding companies has subsidiaries that are 
depository institutions that could be required to adopt Basel II. Each 
of these banking institutions is regulated by a primary federal 
regulator according to the rules under which it is chartered. 

* FDIC serves as the primary federal regulator of state chartered banks 
that are not members of the Federal Reserve System (state nonmember 
banks). It is also the deposit insurer for all banks and thrifts and 
has backup supervisory authority for all banks it insures. 

* The Federal Reserve serves as the primary federal regulator for state 
chartered banks that are members of the Federal Reserve System (state 
member banks). 

* OCC serves as the primary federal regulator for national (i.e., 
federally chartered) banks. Many of the nation's largest banks are 
federally chartered. 

* OTS serves as the primary federal regulator for all federally insured 
thrifts. 

Under the dual federal and state banking system, state chartered banks 
are supervised by state regulatory agencies in addition to a primary 
federal regulator. 

In 2004, SEC established a voluntary, alternative net capital rule for 
broker-dealers whose ultimate holding company consents to groupwide 
supervision by SEC as a CSE. This alternative net capital rule permits 
the use of statistical models for regulatory capital purposes. At the 
holding company level, CSEs are required to compute and report to SEC 
capital adequacy measures consistent with the standards in the Basel 
Accord, and SEC expects them to maintain certain capital ratios, though 
they are not required to do so. According to SEC, all CSEs have 
implemented Basel II. Primary U.S. broker-dealers affiliated with CSEs 
are required to comply with a capital requirement that SEC says is not 
identical to the Basel standards but makes use of statistical models in 
its computation. Depository institutions within the CSEs are subject to 
the same requirements as other banks of similar sizes and exposures 
including risk-based capital requirements, the leverage ratio, and PCA; 
however, there is no leverage requirement at the consolidated level for 
CSEs. 

Core Banks Compete among Themselves and with Other Financial Entities 
That Will Operate under Different Capital Regimes: 

Core banks face a range of competitors including non-core U.S. banks, 
other financial institutions, and foreign-based banks. Core banks that 
have varying business models--some focus on domestic retail banking 
activities, some on wholesale activities, and others are engaged in the 
full range of these activities--are overseen by a number of different 
bank regulators. Banks of different sizes that are likely to be under 
different capital regimes are more likely to compete with each other in 
retail markets, where they offer products such as residential mortgages 
to the same customers, than in wholesale markets. In certain wholesale 
markets, core banks often compete with U.S. investment firms. U.S.- 
based core banks also compete with foreign-based banks in foreign 
markets and in U.S. markets where foreign-based banks are very active. 
Since core banks compete with other financial institutions across 
various product and geographic markets, differences in capital rules or 
the implementation of those rules may have competitive effects by 
influencing such things as the amount of capital institutions hold, how 
banks price loans, and the cost of implementing capital regulations. 

Core Banks Compete with Other Core and Non-core Banks: 

Core banking organizations--those that meet the requirements in terms 
of asset size and foreign exposure for mandatory adoption of the Basel 
II advanced approaches--have adopted a variety of business models, but 
all compete with some other core banks. Some of the core banks are 
active in retail markets, some in wholesale markets, and some in the 
full range of banking activities. As illustrated in table 1, which is 
based on publicly available information, five core banking 
organizations--including one that is foreign-based--have at least 25 
percent of their assets in retail markets and one of these, the only 
thrift that is a core banking organization (Washington Mutual Bank), 
has more than 60 percent of its assets in retail markets, while a few 
institutions have almost no activity in these markets. In addition, two 
core banks that appear less active in retail markets--with about 15 
percent of their assets in these markets--may still have a major 
presence there because of their overall size. In wholesale markets, 
table 1 shows that some banks are active in making commercial and 
industrial loans while others hold a larger percentage of their assets 
as trading assets--assets held to hedge risks or speculate on price 
changes for the bank or its customers. However, the thrift institution 
has very little activity in these markets. The three smaller U.S.-based 
core banks, which are classified as core banks because they have large 
foreign exposures, engage primarily in custodial activities where they 
manage the funds of their clients. In this area they compete with the 
largest U.S. banks that are also engaged in these activities.

Core banks are in some ways similar to non-core banks. For example, 
banks of all sizes continue to participate in some activities 
historically associated with banking-, such as taking deposits and 
making loans. As table 2 shows, bank holding companies of different 
sizes hold similar proportions of certain loans such as residential 
mortgages and commercial and industrial loans.

[End of table] 

According to research conducted by Federal Reserve staff and other 
experts, banks of different sizes compete with each other for retail 
products such as residential mortgages.[Footnote 17] As illustrated in 
table 2, bank holding companies in all size ranges hold a relatively 
large percentage of their assets--from 15.5 to 23.1 percent--in 
residential mortgages. Customers can obtain mortgages from banks across 
the United States and generally can obtain pricing information from 
brokers or directly through the Internet or financial publications. For 
small thrifts, which make up a portion of the small non-core banking 
institutions in the United States but are not included in table 2, the 
proportion of mortgages is much higher.[Footnote 18] Unlike residential 
mortgages, only a few banks, including several core banks, are active 
in the credit card market, but some non-core banks are active in this 
market as well; and all credit card issuers generally compete for the 
same customers.[Footnote 19] 

For wholesale products, the competitive landscape is more complex. As 
table 2 illustrates, in some areas core banks differ substantially from 
non-core banks and are thus not likely to compete with them in those 
markets. For example, non-core banks hold a very small percentage of 
their assets as trading assets, an area where some core banks are very 
active, and core banks hold a relatively small proportion of their 
assets in commercial real estate, an area where non-core banks are very 
active. While table 2 shows that core and non-core banks are both 
active in the commercial and industrial loan markets, the market for 
loans from large banks may be quite different from those for smaller 
banks. According to a bank official and other experts, larger banks do 
not price commercial and industrial loans individually; instead, these 
loans generally are part of a package of products and services offered 
to major corporate clients. Financial market experts told us that often 
these loans are discounted to establish a relationship with the 
customer. Because smaller banks do not offer a full range of products 
and services, they likely are not competing for the same customers as 
larger banks. In addition, we and others have shown that smaller banks 
tend to serve the needs of smaller businesses with which they can 
establish a personal relationship.[Footnote 20] Because obtaining 
credit information on small businesses is difficult, community banks 
often have an advantage with these customers in that they may have 
better information about small businesses in their local market than do 
large national or internationally active banks. As a result, the 
largest banks are unlikely to be competing with community banks in 
these markets. At the same time, research conducted by Federal Reserve 
staff has shown that large non-core banks may compete with core banks 
for corporate customers.[Footnote 21] 

In Some Markets, Core Banks Compete with Other U.S. Financial 
Institutions: 

Core banks are much more likely than smaller or regional non-core banks 
to participate in activities often associated with investment banking. 
For example, core banks are much more likely to hold trading assets 
that typically are used to hedge risks or speculate on certain market 
changes either for the banking organization or its customers (see table 
2). 

In addition, core banks are involved in international activities where 
they often provide investment banking products and services in the 
major capital markets around the world. In the United States and 
abroad, U.S.-based core banks, especially Citigroup and JPMorgan Chase, 
compete with the four major U.S. investment firms---Goldman Sachs, 
Merrill Lynch, Morgan Stanley, and Lehman Brothers. The core banks also 
are involved in custodial and asset management activities domestically 
and internationally. In this capacity, core U.S.-based banks compete 
with foreign-based banks, with investment firms, and with asset 
management firms that do not own depository institutions and are not 
subject to regulatory capital requirements. 

U.S.-Based Banks Compete with Foreign-Based Banks in Foreign and U.S. 
Markets: 

Basel capital requirements were established, in large part, to limit 
competitive advantages or disadvantages due to differences in capital 
requirements across countries; however, the New Basel Accord allows for 
certain areas of national discretion and this could create competitive 
advantages or disadvantages for banks competing in various countries. 
In addition, because a major part of Basel II involves direct 
supervision of the risk management processes of individual banks, 
further opportunities exist for differences across countries to develop 
as the new rules are implemented. 

While all but one of the core banks has some foreign exposure, some of 
the nine U.S.-based core banks have foreign exposures that are large 
relative to the size of the institution (see fig. 2). As noted above, 
most of these banks are engaged in asset management and investment 
banking activities globally. In addition, one of the banks is heavily 
engaged in retail banking activities in a wide range of countries where 
each country likely comprises a separate market. To the extent that 
U.S.-based banking institutions that have subsidiaries in foreign 
countries face more stringent capital requirements for the parent 
institution at home, U.S.-based banks could be disadvantaged in foreign 
markets.

[End of figure] 

Much of the competition between U.S.-and foreign-based banks takes 
place in the United States, where foreign based-banks are very active 
through their subsidiaries, branches, and offices. Foreign-based banks 
account for about $2.8 trillion of the approximately $15 trillion of 
U.S. banking assets and subsidiaries of those banks account for 11 of 
the 50 largest U.S. bank holding companies. Further, as noted in table 
1, three of the core banks in the United States are subsidiaries of 
foreign-based banks. Two of these operate primarily in wholesale 
markets, while the third, HSBC, is active in both retail and wholesale 
banking markets in the United States. In addition, some large U.S. non- 
core banks that are subsidiaries of foreign-based banks are likely to 
adopt the advanced approaches in the United States. 

The extent to which differences in capital requirements will affect 
competition in the United States between U.S.-based and foreign-based 
banks will depend, in part, on how the U.S. activities of the foreign- 
based banks are organized. For capital purposes, although foreign-based 
banks with U.S. subsidiaries will likely follow the Basel II rules in 
their home countries, the U.S. subsidiaries are regulated as U.S. banks 
within the United States and will follow U.S. rules. However, branches 
of foreign banks are not required to meet the U.S. rules. As a result, 
some foreign-based banks that have substantial U.S. operations, but 
conduct their banking activities in the United States through branches, 
will be following the Basel II rules in their home country rather than 
in the United States. 

Differences in Capital Requirements Have the Potential to Create 
Competitive Disparities: 

Because holding capital is costly for banks, differences in regulatory 
capital requirements could influence costs, prices, and profitability 
for banks competing under different capital frameworks. If regulatory 
capital requirements increase the amount of capital banks hold relative 
to what they would hold in the absence of regulation, then the 
requirements would increase banks' costs and reduce their 
profitability.[Footnote 22] Depending on the structure of markets, 
these higher costs could be passed on to bank customers in the form of 
higher prices--interest rates on loans or fees for services--or 
absorbed as reduced lending and profits. For example, higher capital 
costs driven by higher capital requirements could result in a 
competitive disadvantage for banks that compete for similar customers 
with banks subject to different capital rules. Conversely, lower 
capital requirements that allow banks to reduce the capital they hold 
for a particular asset could allow them to price those assets more 
aggressively, thereby increasing market share or earning higher returns 
at existing prices. 

Bank officials with whom we spoke and some empirical evidence we 
reviewed suggested that regulatory capital requirements are one of 
several key factors banks consider in deciding how much capital to 
hold. Other factors include management views on the amount of capital 
the firm needs internally and market expectations.[Footnote 23] These 
multiple and overlapping motivations for holding capital make it 
difficult to isolate the impact of regulatory capital on the amount of 
capital banks hold.[Footnote 24] Nevertheless, there is some evidence 
that banks hold more than the minimum required capital--a buffer--in 
part to reduce the risk of breaching that minimum requirement. For 
example, one study of United Kingdom banks found that an increase in 
required capital was followed by an increase in actual capital, 
although the increase was only about half the size of the increase in 
required capital.[Footnote 25] Thus, changes in minimum required 
capital could cause banks to change the amount of capital they hold to 
maintain a similar buffer of capital, consistent with the other goals 
of the bank. The study also found that banks with small buffers reacted 
more to a given change in individual capital requirements--and banks 
with larger buffers reacted little, if at all--supporting the view that 
the capital buffer is a form of insurance against falling below 
regulatory minimums. 

Differences in the implementation costs of capital requirements also 
could have competitive effects. In principle, higher implementation 
costs could lead to a one-time increase in costs or ongoing costs 
associated with compliance. One-time costs would influence 
profitability directly, while ongoing costs also could influence the 
cost of lending for banks in the same way that higher capital costs 
could influence pricing and profitability. Significant implementation 
costs are likely to be easier to bear the larger the institution--the 
costs of implementing regulation are on average higher (as measured by 
cost per employee) for smaller firms.[Footnote 26] 

The possible effects of differences in regulatory capital requirements 
on implementation and capital costs also could influence incentives for 
consolidation by making acquisitions more or less advantageous for 
banks operating under different capital rules. Such advantages would 
imply that those banks under a given capital regime might be able to 
use the capital resources of banks under a different regime more 
effectively, making it profitable for the former banks to acquire the 
latter ones. Conversely, if implementation costs for a capital regime 
imposed on larger banks were high, this might discourage some banks 
from merging because they would become large enough to be required to 
adopt a capital regime with high implementation costs. 

New U.S. Capital Rules Have Reduced Some Competitive Concerns about 
Basel II: 

The new U.S. capital rules address some competitive concerns of banks; 
however, other concerns remain. Regulators analyzed some competitive 
issues raised by banks during the development of the Basel II rules in 
the United States. In the final rule for the advanced approaches, the 
regulators addressed concerns about differences between the NPR and the 
New Basel Accord that could have led to greater implementation costs. 
For example, in the final rule they harmonized the definition of 
wholesale loan default with the accord, thus responding to banks' 
concerns that differences in the definition of wholesale loan default 
between the NPR and the accord could have led to increased costs of 
operating in multiple countries. However, core banks remain concerned 
that the leverage requirement will affect their ability to compete with 
both foreign-and some U.S.-based competitors. The coordination between 
U.S. and foreign regulators on implementation issues for core banks may 
address some competitive concerns of internationally active core banks. 
For non-core banks, the proposed standardized approach rule may address 
some concerns--for example, that core banks could hold less capital for 
similar assets. The proposed rule is more risk sensitive than Basel I, 
providing non-core banks with the possibility of lower regulatory 
capital minimums for certain assets or activities. Other factors, such 
as the leverage requirement, may reduce differences in capital for 
banks competing in the United States. 

U.S. Regulators Recognized Some Competitive Concerns during the 
Development of the Rules: 

As a result of the potential for large banks to hold less capital under 
Basel II, at least for certain assets, researchers, primarily at the 
Federal Reserve, conducted studies of the potential impact of Basel II 
on specific markets and on aspects of the rule, including the impact on 
residential mortgages, credit cards, operational risk, and mergers and 
acquisitions. These studies were limited by the availability of data 
and by a lack of information on the impact regulatory capital has on 
bank behavior. Nonetheless, the studies identified that there could be 
competitive impacts in the residential mortgage market and helped to 
lead to the development of alternatives to Basel I for non-core banks. 

OCC and OTS provided the Office of Management and Budget (OMB) with 
regulatory impact analyses that included examination of the impact of 
the rules on domestic competition.[Footnote 27] In addressing 
competitive issues in this analysis, OCC relied primarily on the 
studies conducted at the Federal Reserve. In its regulatory impact 
analysis, OTS incorporated OCC's analysis adding appropriate material 
specifically related to the thrift industry. For example, OTS noted 
that because thrifts have high concentrations of assets in residential 
mortgages, the leverage requirement would be more likely to impose 
greater capital requirements on these firms than would the Basel II 
requirements and, as a result, would have a negative impact on the 
ability of thrifts to compete with other banking organizations. OTS 
also pointed out that interest rate risk for those mortgage-related 
assets that a bank is planning to hold rather than trade is 
particularly important to thrifts. However, the adequacy of capital 
held for these risks is being assessed in Pillar 2 rather than in 
Pillar 1, where the risks associated with changes in interest rates on 
mortgage related assets that are being actively traded are assessed. 
Since there is more regulatory flexibility in Pillar 2 than in Pillar 
1, OTS expressed concern that thrifts could be disadvantaged if 
different regulatory agencies did not implement Pillar 2 consistently. 

The regulators did less analysis regarding the international 
competitive impact of the new rules. At the time that the capital rules 
were being developed, OMB provided little guidance on analyzing the 
international impact of U.S. rules and the agencies did not discuss 
international competition issues in their analyses. Alternatively, 
European Union guidance for regulatory impact analyses includes a more 
detailed evaluation of impacts on international trade and investment, 
and OMB is considering including more explicit guidance on the analysis 
of the impact on international trade and investment in the United 
States.[Footnote 28] During the development of Basel II, U.S. banks 
raised concerns about being disadvantaged internationally by certain 
aspects of the U.S. rules. 

U.S. Final Rule on the Advanced Approaches Addresses Some Competitive 
Concerns Raised by Banks, but the Leverage Ratio Continues to Be a 
Concern: 

Although regulators have harmonized some aspects of the advanced 
approaches final rule with the New Basel Accord, concerns remain about 
remaining differences in the final rule and other issues such as the 
leverage requirement that could have competitive effects. The final 
rule removed an important technical difference in the definition of 
default for wholesale products that existed between the U.S. NPR and 
the New Basel Accord. However, other differences were retained, such as 
the U.S. implementation schedule and the amount by which regulatory 
capital could decrease during a bank's transition to the final rule. 
Core banks are specifically concerned that the leverage requirement 
will have negative effects on their ability to compete with CSEs and 
foreign-based banks. 

Final Rule Eliminated Some Technical Differences That Raised Concerns 
about Competitive Effects, but Other Differences Remain: 

U.S. banking regulators harmonized certain aspects of the U.S. final 
rule on the advanced approaches with the New Basel Accord, reducing 
some concerns of core banks. For example, one of the major concerns of 
U.S. core banks was that the proposed rule included a different 
definition of default for wholesale products, which could lead to 
increased implementation costs through the need to maintain separate 
systems for data in the United States and in those foreign countries 
where U.S. core banks were required to adopt Basel II. The definition 
of default for wholesale products in the final rule now closely 
resembles the New Basel Accord's definitions for these types of 
products, thus limiting the potential for higher implementation costs 
for core banks. Other technical differences that have been diminished 
for core banks include how core banks have to estimate their losses 
after a borrower has defaulted on a loan. Table 3 outlines several key 
technical differences between the earlier proposed U.S. rules and the 
New Basel Accord and highlights where U.S. regulators diminished or 
retained differences in the final rule. 

Table 3: Significant Technical Differences between the U.S. NPR on 
Advanced Approaches and the New Basel Accord, and the Treatment of 
These Differences in the U.S. Final Rule on Advanced Approaches: 

Significant technical differences: Wholesale definition of default; 
U.S. NPR on the Advanced Approaches: Based on whether: 
* the bank places any exposure to the borrower on non-accrual status,; 
* the bank incurs full or partial charge offs on any exposure to the 
borrower, or; 
* the bank incurs a credit-related loss of 5 percent or more on the 
sale of any exposure to the borrower or transfer of any exposure to the 
borrower to the held-for-sale, available-for-sale, trading account, or 
other reporting category; 
New Basel Accord: Based on whether: 
* the bank considers a borrower unlikely to pay in full without 
recourse to bank actions, or; 
* a borrower's payment on principal or interest is more than 90 days 
past due; 
* Includes non-accrual status and material credit-related loss on sale 
as elements indicating unlikeliness to pay. However, the accord does 
not specify the threshold of 5 percent for credit-related losses upon 
sale or transfer, and other countries' definitions do not generally 
include non-accrual status; 
U.S. Final Rule on Advanced Approaches: Based on whether: 
* the bank considers that the borrower is unlikely to pay its credit 
obligations to the bank in full, without recourse by the bank to 
actions such as realizing collateral (if held), or; 
* the borrower is past due more than 90 days on any material credit 
obligation to the bank; 
* Includes nonaccrual and material credit-related loss on sale as 
elements indicating unlikeliness to pay. 

Significant technical differences: Retail definition of default; 
U.S. NPR on the Advanced Approaches: Occurs when an exposure reaches 
120 or 180 days past due, depending on exposure type, or when the bank 
incurs a full or partial charge off or write-down on principal for 
credit- related reasons; 
New Basel Accord: Occurs when an exposure reaches a past due threshold 
between 90 and 180 days, set by the national supervisor, or when the 
bank considers a borrower unlikely to pay in full without recourse to 
bank actions; 
U.S. Final Rule on Advanced Approaches: * Occurs when an exposure 
reaches 120 or 180 days past due, depending on exposure type, or when 
the bank incurs a full or partial charge-off or write-down on principal 
for credit-related reasons; 
* Banks can adopt the definition of default of host countries for 
foreign subsidiaries subject to prior approval of their primary federal 
supervisor. 

Significant technical differences: Small-and medium-sized enterprise 
(SME) lending; 
U.S. NPR on the Advanced Approaches: Does not include an adjustment 
that would result in a lower capital requirement for loans to SMEs 
compared to other business loans under the framework; 
New Basel Accord: Includes such an adjustment; 
U.S. Final Rule on Advanced Approaches: Does not include an adjustment 
that would result in a lower capital requirement or loans to SMEs 
compared to other business loans. 

Significant technical differences: Loss given default (LGD); 
U.S. NPR on the Advanced Approaches: * A bank may use its own LGD 
estimates upon obtaining supervisory approval, which is based in part 
on whether the estimates are reliable and sufficiently reflective of 
economic downturn conditions; 
* A bank that does not qualify to use its own internal LGD estimates 
must instead compute LGD using a supervisory formula that some bank 
officials have described as overly conservative; 
New Basel Accord: * Requires banks to estimate losses from default that 
would occur during economic downturn conditions, which may result in 
higher regulatory required capital for some exposures under the 
framework; 
* Does not identify an explicit supervisory formula for estimating LGD 
when a bank's internal LGD estimates do not meet minimum requirements; 
* Instead, if a bank is unable to estimate LGD for any material 
portfolio, it would not qualify for the A-IRB approach; 
U.S. Final Rule on Advanced Approaches: Bank's LGD estimate must be 
reliable and sufficiently reflective of economic downturn data and 
should have rigorous and well-documented policies and procedures for 
(1) identifying economic downturn conditions for each exposure 
subcategory, (2) identifying changes in material adverse relationships 
between the relevant drivers of default rates and loss rates given 
default, and (3) incorporating identified relationships into LGD 
estimates.

[End of table] 

One technical difference that remains between the U.S. final rule on 
advanced approaches and the New Basel Accord is the treatment of SME 
loans. U.S. regulators believe that an adjustment to lower the capital 
charge for such business loans is not substantiated by sufficient 
empirical evidence. In other words, this suggests that, all other 
things equal, SME loans have risks comparable to those posed by larger 
corporate loans. U.S. regulators also noted that the SME treatment in 
the Accord might give rise to a domestic competitive inequity between 
core banks and banks subject to other regulatory capital rules, such as 
Basel I. Officials at one rating agency with whom we spoke said that a 
lower capital requirement for SME loans in the New Basel Accord was not 
reflective of the risk for these exposures, and the rating agency did 
not treat these loans differently from other business loans in their 
own assessments of capital adequacy. In addition, several experts with 
whom we spoke noted that this difference in capital requirements for 
SME loans would likely not have any immediate or major impact on 
competition between U.S. and foreign banks. 

In addition to the technical differences discussed above, the final 
rule addressed one concern related to a prudential safeguard U.S. 
regulators introduced in the 2006 NPR, but some core banks remain 
concerned about the implementation schedule. The NPR contained a 
benchmark--a 10 percent reduction in aggregate minimum capital among 
core banks--that would have been viewed as a material reduction in 
capital requirements that warranted modification in the rule. Core 
banks had commented that this safeguard could affect them negatively 
because of the uncertainty surrounding its application. In the final 
rule, U.S. regulators eliminated the benchmark. However, retention of 
the implementation schedule proposed in the 2006 NPR continues to raise 
concerns for some core banks because it will lead to a longer 
transition period in the United States than in other countries and 
delay any possible capital reductions. European banks and most Canadian 
banks on the advanced approaches most likely will exit their 
transitional periods by January 2010. In contrast, U.S. core banks 
cannot exit their transitional periods before April 2012 and could do 
so in 2014 or later. Furthermore, European banks will be able to reduce 
capital to 90 percent of Basel I requirements in 2008 and to 80 percent 
of Basel I requirements in 2009 while Canadian banks will be able to 
apply for approval to reduce their capital by similar amounts under the 
same timeframes. Under the final rule, U.S. core banks will have three 
distinct transitional periods during which required risk-based capital 
may be reduced to only 95 percent, 90 percent, and 85 percent of Basel 
I requirements respectively.[Footnote 29] The different implementation 
schedules and maximum capital reductions may provide foreign 
competitors of U.S. core banks an earlier opportunity to make use of 
any decreases in capital costs associated with lower required capital 
for certain assets or activities. Therefore, by making the transition 
to Basel II lengthier for U.S. core banks, foreign competitors may be 
able to take better advantage of strategic opportunities, such as a 
mergers or acquisitions. Though several core bank officials with whom 
we spoke remained concerned about the time difference, officials at one 
core bank explained that the current market environment may limit the 
competitive implications of that difference. 

Several core bank officials with whom we spoke mentioned that they 
would have wanted to have the option to select the standardized 
approach with some officials suggesting that the lack of a choice may 
lead to higher implementation costs. In the United States, the final 
rule requires all core banks to adopt the advanced approaches for both 
credit and operational risk, but affords opportunities for the primary 
federal supervisor to exercise some flexibility when applying the final 
rule to core banks. The advanced approaches rule specifically allows 
for the exemption of subsidiary depository institutions from 
implementing the advanced approaches, and, under the reservation of 
authority, the primary federal regulator can require a different risk 
weighted asset amount for one or more credit risk exposures, or for 
operational risk, if the regulators determine that the requirement 
under the advanced approaches is not commensurate with risk. However, 
some U.S. regulatory officials with whom we spoke noted the potential 
risk of a piecemeal approach and emphasized that they do not want banks 
to apply the advanced approach for credit risk to their least risky 
portfolios and to apply Basel I or the proposed standardized approach 
for their riskier portfolios. 

In contrast, some foreign banks have not been explicitly required to 
adopt the advanced approaches for credit and operational risk. For 
example, Canadian regulators told us that they have an expectation for 
their domestic banks with significant global operations to move to the 
advanced approach for credit risk and that there is no such expectation 
for domestic banks to use the advanced approach for operational risk. 
Furthermore, all other banks in Canada can decide to adopt the advanced 
approaches with the condition that the bank must adopt the advanced 
approach for credit risk before adopting the advanced approach for 
operational risk. In addition, regulatory officials from the United 
Kingdom told us that all banks were required to adopt the standardized 
approach in 2007, but some banks applied for a waiver to allow them to 
adopt the advanced approaches for determining capital requirements for 
credit risk or for operational risk. Moreover, officials from one 
European bank told us that they entered their first transitional year 
in their country with approximately three-quarters of their portfolios 
on the advanced approach for credit risk. 

Retention of Leverage Requirement Has Raised Concerns of Core Banks 
about Competitive Effects: 

Officials from some of the core banks with whom we spoke expressed 
concerns that they may be at a competitive disadvantage due to the 
retention of the U.S. leverage requirement, which applies to all 
depository institutions and U.S.-based bank holding companies. Foreign 
banks based in other industrialized countries are generally not subject 
to a leverage requirement.[Footnote 30] Some U.S.-based core banks are 
concerned about the impact of the leverage requirement for bank holding 
companies on their operations abroad. That is, in meeting the leverage 
requirement, a U.S. bank holding company must include the assets of its 
foreign operations, potentially increasing the amount of required 
regulatory capital in comparison with the regulatory capital 
requirements for foreign-based bank holding companies. For example, the 
additional capital needed to meet the leverage requirement may exceed 
the additional capital required under the advanced approaches for 
certain corporate loans that are estimated by banks to be relatively 
low-risk, as demonstrated in figure 3. Most core bank officials with 
whom we spoke also said that by maintaining the leverage requirement, 
U.S. regulators were preserving a regulatory capital requirement that 
was not aligned with the improved risk-management practices promulgated 
by the final rule on the advanced approaches. Officials from one trade 
association said that because the leverage requirement does not require 
additional capital as risk increases, banks may have an incentive to 
increase their return on equity by holding assets with higher risk and 
return, but no additional capital required by the leverage requirement. 
In contrast, regulatory officials have stated that risk-based and 
leverage requirements serve complementary functions in which the 
leverage requirement can be seen as offsetting potential weaknesses or 
supplementing the risk-based capital requirements.

Note: Estimates of the capital required under the advanced approaches 
in the figure assume an LGD of 35.8 percent (adjusted for downturn 
conditions using the supervisory formula from the advanced approaches 
NPR, based on mean LGD for corporate, bank, and sovereign exposures 
from the fourth quantitative impact study (QIS-4 ) of 30.2 percent), 
and a maturity of 1 year. The leverage requirement of 3 percent for 
bank holding companies subject to the market risk amendment is measured 
in tier 1 capital, while the Basel II credit risk requirement is 
measured in total capital. The estimates of required capital under the 
advanced approach do not include any increase in the operational risk 
capital requirement that could come from holding additional assets. 

[End of figure] 

In terms of potential competitive effects domestically, some core bank 
officials with whom we spoke expressed concerns that certain financial 
firms, primarily the CSEs, offer similar wholesale products but lack 
similar regulatory capital requirements, while other core bank 
officials were no longer concerned. As noted previously, CSEs are 
required to compute and report to SEC capital adequacy measures 
consistent with the standards in the New Basel Accord, and SEC expects 
them to maintain certain capital ratios, though they are not required 
to do so. SEC has said that it will make modifications in light of the 
final rule adopted by U.S. bank regulators and subsequent 
interpretations. In addition, bank holding companies are subject to a 
leverage requirement, but CSEs do not have a similar requirement. For 
example, in December 2007, the leverage ratio for core bank holding 
companies ranged from about 4.0 percent to about 6.8 percent and for 
CSEs ranged from about 3 percent to 3.8 percent. 

International Coordination among Regulators Has Contributed to Reducing 
Competitive Concerns for Core Banks: 

U.S. regulators and their foreign counterparts are coordinating in ways 
that contribute to reducing the potential for adverse competitive 
effects on U.S. banks operating abroad. These efforts aim to resolve 
some issues that develop between regulators in a bank's home country 
and those in other countries where the bank operates, usually referred 
to as home-host issues. Handling home-host issues is an essential 
element of the New Basel Accord framework because it allows for 
national discretion in a number of areas.[Footnote 31] Several foreign 
regulators with whom we spoke discussed how well U.S. regulators have 
been able to collaborate with their foreign counterparts on a variety 
of supervisory issues. Specific to Basel II implementation, U.S. 
regulators have been able to provide needed information to foreign bank 
supervisors that could limit the compliance costs of subsidiaries of 
U.S. banks operating abroad. For example, OCC examiners explained to us 
how they assisted a foreign regulator in better understanding some of 
the information a core bank was using in estimating credit risk for a 
certain loan portfolio. In another instance of collaboration, foreign 
regulators explained to us that they waived the requirement for a core 
bank to adopt the advanced approaches for its foreign-owned subsidiary 
until the core bank adopted the advanced approaches in the United 
States. 

Over the years, the U.S. regulators have entered into various 
information-sharing agreements that facilitate cooperation with their 
foreign counterparts. These agreements are intended to expedite the 
meeting of requests posed by foreign regulators for supervisory 
information from U.S. regulators. As of July 2008, OCC and Federal 
Reserve officials explained that they had some form of an information- 
sharing agreement with 25 and 16 foreign jurisdictions respectively. 
Likewise, FDIC and OTS officials both described good working 
relationships with their foreign counterparts as they related to U.S. 
banks with international operations that they supervise. 

U.S. regulators have been and continue to be active members in the 
Basel Committee and its various subcommittees, including the Accord 
Implementation Group. In addition, U.S. regulators participate in 
colleges of supervisors and other international bodies, such as the 
Joint Forum.[Footnote 32] Participation in such entities further 
provides U.S. regulators information on how U.S. banks may be treated 
by foreign regulators, thus allowing for more dialogue among regulators 
to preemptively address any home-host issues. The Accord Implementation 
Group's purpose is to exchange views on approaches to implementation of 
Basel II, and thereby to promote consistency in the application of the 
New Basel Accord. Colleges of supervisors are meetings at which 
regulators from various countries discuss supervisory matters that 
relate to a specific bank that has global operations. Officials from 
the Federal Reserve stated that the colleges are more often better for 
sharing information among regulators than for addressing a specific 
regulatory issue. Though regulators from various countries are sharing 
information, several core banks expressed concerns to us that their 
foreign regulators have been implementing Basel II differently. 

Proposed Standardized Approach May Reduce Competitive Concerns of Non- 
core Banks, as May Other Factors: 

As discussed earlier, because non-core banks compete with core banks in 
some markets, non-core banks were concerned that core banks would be 
able to hold less capital than non-core banks were holding under Basel 
I for the same assets. Part of this concern came from the April 2005 
results of the fourth quantitative impact study (QIS-4), which 
estimated that Basel II could result in material reductions in 
aggregate minimum required risk-based capital among potential core 
banks.[Footnote 33] By holding less capital for certain products, such 
as residential mortgages, core banks might charge less for these 
products than non-core banks. Two studies of the potential impact of 
Basel II on the market for residential mortgages have disagreed as to 
the magnitude of any competitive impact--one suggested a potentially 
significant shift in income from mortgages toward banks on the advanced 
approaches, while the other argued that any competitive impact was 
unlikely.[Footnote 34] In addition, U.S. regulators have recognized 
that some banks were concerned about core banks being required to hold 
less capital overall, thus making it advantageous to acquire non-core 
banks. The proposed standardized approach rule should address some of 
the competitive concerns non-core banks expressed in the early 2000s, 
while several other factors, including the leverage requirement, also 
may reduce differences in capital between core and non-core banks. 

Proposed Standardized Approach Provides a More Risk-sensitive Option 
for Non-core Banks: 

U.S. regulators have proposed the standardized approach in part to 
mitigate potential competitive differences between core and non-core 
banks.[Footnote 35] The U.S. version of the standardized approach 
features more risk-sensitive capital requirements than Basel I. In 
particular, it adds risk sensitivity for mortgages based on their loan- 
to-value (LTV) ratios and has lower capital requirements than Basel I 
for some lower-risk (lower LTV) mortgages (see fig. 4). 

Figure 4: Risk Sensitivity of Proposed Standardized Approach vs. 
Prudently Underwritten Residential Mortgages under Basel I, by LTV: 

This figure is a combination bar graph showing risk sensitivity of 
proposed standardized approach vs. prudently underwritten residential 
mortgages under Basel I, by LTV. One bar shows Base I, and the other

Base I: 4;

Base I: 4; 
Proposed U.S. standardized approach: 12.

Source: GAO analysis of the standardized proposal. 

Note: Estimates of required capital under the standardized approach in 
the figure do not include any increase in the operational risk capital 
requirement that could come from holding additional assets. Mortgage 
loans that are not prudently underwritten would receive a 100 percent 
risk weight under Basel I. Banks must demonstrate that mortgage loans 
with a LTV that exceeds 90 percent are prudently underwritten to 
receive the 50 percent Basel I risk weight. 

[End of figure] 

The proposed standardized approach rule is also similar to the 
standardized approach under the New Basel Accord in that, like the 
accord, it features increased risk sensitivity for some externally 
rated exposures, including corporate loans. This is in contrast to the 
single risk weight for corporate credits and most mortgages in Basel I. 
Figure 5 demonstrates that the minimum required capital under the 
standardized approach for the credit risk associated with externally- 
rated corporate loans will be much more similar to that required under 
the advanced approaches than that required under Basel I. In addition, 
the standardized approach expands incentives for better risk management 
in that it allows banks to reduce capital in light of certain 
additional practices that could reduce risk, such as the use of 
collateral or third-party guarantees, and explicitly requires banks to 
set aside capital for operational risk. The added risk sensitivity of 
the standardized approach proposal should reduce some differences in 
risk-based capital requirements, as compared with the advanced 
approaches, for adopting banks.

30.2 percent and 39.4 percent, respectively), and a maturity of 3 
years. Default probabilities, from Moody's, are 0.03 percent for AAA, 
Aa, and A (the lower bound in the advanced approaches rule), 0.18 
percent for Baa, 1.21 percent for Ba, 5.24 percent for B, and 19.48 
percent for C. We include a range of estimates for the advanced 
approach for credit risk because it allows for greater granularity of 
risk assessments than the standardized approach and because banks may 
use a variety of methodologies and different underlying data for 
estimating risk parameters. The estimates of required capital under the 
advanced and standardized approaches do not include any increase in the 
operational risk capital requirement that could come from holding 
additional assets. 

[End of figure] 

Once the standardized approach rule becomes final, non-core banks will 
have the option of choosing it or the advanced approaches, or remaining 
on Basel I. Presumably, non-core banks will take into consideration a 
wide range of issues when deciding what regulatory capital framework to 
adopt, including potential competitive effects. For example, a growing 
non-core regional bank that competes principally with core banks in 
wholesale and retail lending may find it beneficial to adopt the 
advanced approaches in order to model and receive lower risk-based 
capital requirements for certain lower-risk credits. Similarly, a 
smaller non-core bank that found itself increasingly competing with 
regional banks might opt for the additional risk-sensitivity of the 
standardized approach. However, one trade association representing some 
of the smallest non-core banks with whom we spoke said the standardized 
approach may not fully address the competitive concerns of these banks 
because the capital relief associated with holding some lower risk 
assets might be offset by additional capital required for operational 
risk. Officials at one large non-core bank told us that the bank was 
considering all of its options carefully and noted that there were a 
large number of factors to consider in deciding which risk-based 
capital rule to adopt. 

Other Factors, Such as the Leverage Requirement, May Reduce Competitive 
Effects of Multiple U.S. Capital Rules: 

While the leverage requirement, particularly for bank holding 
companies, remains a competitive concern for core banks, the leverage 
requirements that all depository institutions must meet may limit 
competitive differences resulting from banks in the United States 
operating under multiple risk-based capital rules. Because these 
banking institutions must meet both risk-based and leverage 
requirements, the leverage requirement may be the effective or binding 
requirement for lower-risk assets held on the balance sheet, or more 
generally for banks with a relatively low-risk portfolio. The 
additional capital needed to meet the leverage requirement likely will 
exceed both the additional advanced and standardized approaches risk- 
based capital requirements for certain lower-risk assets held on 
balance sheets, such as low LTV mortgages and highly rated corporate 
credits.[Footnote 36] Figure 6 compares the capital required by the 
advanced approaches with the capital required by the leverage 
requirement for certain externally rated corporate loans.

Moody's Investors Service and the QIS-4 summary. 

Note: Estimates of required capital under the advanced approaches in 
figure 6 assume a LGD of 35.8 percent (adjusted for downturn conditions 
using the supervisory formula from the advanced approaches NPR, based 
on median LGD for corporate, bank, and sovereign exposures from QIS-4 
of 30.2 percent), and a maturity of 3 years. Default probabilities, 
from Moody's, are 0.03 percent for AAA, Aa, and A (the lower bound in 
the advanced approaches rule); 0.18 percent for Baa; 1.21 percent for 
Ba; 5.24 percent for B; and 19.48 percent for C. The leverage 
requirement of 4 percent for depository institutions is measured in 
tier 1 capital, while the Basel II credit risk requirement is measured 
in total capital. The estimates of required capital under the advanced 
approach do not include any increase in the operational risk capital 
requirement that could come from holding additional assets. 

[End of figure] 

Because U.S. banks hold capital for a number of reasons and are 
generally expected to hold more than the minimum amount of capital 
required, banks under different risk-based capital rules may 
nevertheless hold similar capital for similar assets and activities-- 
and therefore have similar capital costs--despite differences in 
minimum required capital. As already discussed, banks hold capital 
based on management views on the amount of capital the bank needs 
internally and market expectations, in addition to regulatory 
requirements. Furthermore, regulators generally expect banks to hold 
capital above these minimum requirements, commensurate with their risk 
exposure. For example, as part of Pillar 2, banks and regulators will 
assess risks not covered or not adequately quantified by Pillar 1 
minimum requirements. 

Another factor that may reduce competitive effects resulting from 
differences in risk-based capital requirements is the ability of banks 
to originate loans and subsequently securitize and sell them to other 
entities. Differences in required capital for credit risk across 
multiple risk-based regimes would likely have a competitive impact only 
to the extent that banks retain the credits they originate on their 
balance sheets or retain a significant portion of the credit risk off 
their balance sheets. Banks may securitize residential mortgages and 
other types of loans into other marketable investments in order to 
raise further funds to originate additional loans. This is also known 
as an originate-to-distribute model where revenues are derived from the 
sale of assets rather than an ongoing stream of interest payments. 
However, the recent turmoil in the credit markets has reduced the 
volume of some securitizations and highlighted weaknesses in 
underwriting standards associated with the originate-to-distribute 
model. As a result, incentives for securitization could be influenced 
by changes in capital requirements and the market environment. 

Potential Impact of New Rules on Mergers and Acquisitions Is Uncertain: 

The potential impact of the new regulatory capital rules on incentives 
for mergers and acquisitions remains uncertain because it is not clear 
how much capital requirements and other regulatory costs will change 
under the new capital rules. As noted earlier, differences in 
regulatory capital requirements could influence incentives for 
consolidation by making acquisitions more or less advantageous for 
banks operating under different capital rules, such as the multiple 
risk-based capital rules being introduced in the United States. 
However, several industry participants with whom we spoke said that 
mergers and acquisitions generally were driven by strategic concerns 
such as gaining access to a new market rather than capital concerns. In 
addition to the new capital rules, changes in credit markets may be 
affecting the benefits and costs of certain mergers. For example, one 
regional bank told us that the costs of implementing the advanced 
approaches is high especially for smaller banks and that the benefits 
of the advanced approaches were less certain in the current financial 
climate where credit quality has deteriorated. As a result, some 
industry participants said that regional banks may be forgoing mergers 
with each other to avoid being classified as core banks that would have 
to adopt the advanced approaches. 

Bank Regulators Have Taken Limited Actions to Address Additional 
Competitive Effects of Basel II Implementation on U.S. Banking 
Organizations: 

Many factors have affected the pace of Basel II implementation in the 
United States, and while the gradual implementation is allowing 
regulators to consider changes in the rules and reassess banks' risk- 
management systems, regulators have not yet addressed some areas of 
uncertainty that could have competitive implications. The final rule 
provides regulators with considerable flexibility and leaves open 
questions about which banks will be exempted from the advanced 
approaches. Without such clarification, core banks may expend greater 
resources to prepare for implementation than otherwise would be 
necessary. In addition, opportunities for regulatory arbitrage exist if 
regulators use different standards for exemptions. Regulators also have 
not fully developed plans for a required study of the impacts of Basel 
II implementation. Lack of development or specificity in criteria, 
scope, methodology, and timing will affect the quality and extent of 
information that regulators would use to help address competitive and 
other effects and make future changes in the rules. 

A Number of Factors Have Affected the Pace of Basel II Implementation, 
Including Market Turmoil: 

The financial market turmoil that began in the subprime housing market 
in 2007 accounts, in part, for banks' delaying implementation of the 
Basel II advanced approaches. In part, because the economy had been 
experiencing benign conditions, in 2005, U.S. regulators had estimated 
in QIS-4--a study of the potential impact of Basel II as then proposed-
-that minimum capital requirements for credit risk would fall once 
Basel II was fully implemented. And, according to the head of one of 
the regulatory agencies, many were impatient with a gradual approach to 
implementing Basel II at that time. Now that credit markets are 
experiencing turmoil, some bank officials and regulators told us that 
banks will implement Basel II more slowly. 

As a result of the current financial turmoil, regulators have been 
considering modifications in the advanced approaches to Basel II and 
are assessing banks' risk management systems. The Basel Committee has 
been reviewing certain aspects of the capital framework including the 
treatment of securitizations, greater specification of scenario testing 
in Pillar 2, and the treatment of credit risk charges for trading 
assets.[Footnote 37] The Basel Committee is also considering principles 
for sound risk management and supervision related to liquidity risk and 
issued a consultative document on this issue in June 2008.[Footnote 38] 
U.S. regulators have noted that the gradual implementation of Basel II 
in the United States is allowing them to better understand how the 
rules might need to be adapted or implemented in the changed financial 
climate. Regulators have also been speaking to bankers in a number of 
forums on the need to improve risk management practices in relation to 
Basel II. 

Gradual implementation is also built into the advanced approaches. (See 
app. III for an illustration of the timeline for the development and 
implementation of the advanced approaches.) As noted earlier, the 
advanced approaches rule took effect on April 1, 2008. Core banks 
generally must adopt an implementation plan approved by the bank's 
board of directors by October 1, 2008, but do not actually have to 
begin the four intermediate phases that lead to full implementation of 
Basel II until April 1, 2010. If banks begin then and each of the four 
intermediate phases takes a year, they would then be ready to fully 
adopt Basel II by April 1, 2014. At the time the rule took effect, 
banks could start their parallel run, the first of the four 
intermediate phases, at the beginning of any quarter ranging from the 
second quarter of 2008 to the second quarter of 2010. 

The 2007 decision to offer non-core banks an option to adopt the 
standardized approach also has affected the pace of implementation in 
the United States. As a result of comments received on NPRs related to 
Basel II in 2006, U.S. regulators decided to offer non-core U.S. 
banking institutions the option of a standardized approach. Regulators 
issued the NPR in July 2008 but are uncertain as to when they will 
issue a final rule. In addition, the new NPR again asks the question of 
whether core banks should be permitted to adopt the standardized 
approach rather than advanced approaches creating uncertainties that 
will be discussed later. 

Some Uncertainties about Basel II Implementation Remain to Be 
Addressed: 

A primary goal of federal bank regulators is to promote the safety and 
soundness of the banking institutions they oversee. To fulfill this 
obligation, bank regulators must have the authority and flexibility to 
take actions to achieve this objective. The Federal Reserve and OCC 
have taken a number of steps to help ensure that Basel II is 
implemented consistently across the banking organizations they 
supervise and regulators have issued some joint statements and guidance 
to address some of the remaining uncertainty for banks. Nonetheless, 
the flexibility afforded by the rule for the advanced approaches could 
lead to inconsistent application of the rules, which could, in turn, 
produce competitive differences among the banks or provide 
opportunities for regulatory arbitrage. 

The Final Rule for the Advanced Approaches Allows Regulators to 
Exercise Some Regulatory Flexibility: 

A certain amount of flexibility for primary bank supervisors and 
related uncertainty for banks is necessary for maintaining the safety 
and soundness of the banking system. Under the final rule for the 
advanced approaches, regulators can respond to new or unforeseen 
situations that pose risks to safety and soundness without having to 
first change the rule. The rule reserves the authority of primary 
federal bank regulators to require that banks hold an amount of capital 
greater than the minimums dictated by the rule. This authority is being 
maintained both in the application of Pillar 1, where regulators can 
require that a bank calculate required capital in ways that recognize 
the individual situation of that institution and in Pillar 2, which by 
its very nature promotes supervision that uniquely addresses the 
situations of specific banks, while following general principles. For 
example, under the advanced approaches, regulators can generally allow 
U.S.-based banks with foreign subsidiaries to use a different retail 
definition of default for subsidiaries in foreign countries unless the 
primary supervisor determines that the banking organization is using 
the differences in the definitions of default to engage in regulatory 
arbitrage. 

Given the provisions for primary federal regulators to exercise their 
judgment during the implementation of Basel II, the Federal Reserve and 
OCC, which oversee all but one of the banks that meet the asset size 
and foreign exposure criteria for core banks, have taken a number of 
steps to help ensure that Basel II is implemented consistently within 
and across the banking organizations they supervise. As we have noted 
in a previous report, the Federal Reserve has been aware that its 
decentralized structure could lead to inconsistent supervisory 
treatment of large banks it oversees and had developed some procedures 
to limit these differences.[Footnote 39] These procedures include 
having a management group, which consists of officials from the Federal 
Reserve Board of Governors and Federal Reserve District Banks, provide 
additional review of supervisory plans and findings for large, complex 
banks. They have been relying on this process to help ensure 
consistency in the application of Basel II. OCC also has been taking 
actions to help ensure that examiners will implement Basel II in an 
equitable manner across the banks it supervises. Heretofore, the OCC 
examination process permitted lead examiners to provide information to 
banks without obtaining specific input from headquarters staff; 
however, OCC has been requiring that information about Basel II be 
raised to higher levels and that some of the same personnel be involved 
in Basel-related examinations across banks. These two agencies also 
have taken a number of actions to ensure consistent application of 
Basel II across the agencies. For example, Federal Reserve and OCC 
examiners have conducted joint examinations to look at how banks are 
implementing some processes related to the advanced approaches. 

The other two primary bank regulators--OTS and FDIC--which oversee 
fewer core banks, have also participated in activities related to 
ensuring consistency in the implementation of Basel II. OTS is the 
primary regulator for the only thrift that meets the definition of a 
core bank on its own and is thus interested in ensuring that its 
processes for that bank are consistent with those of the other 
regulators overseeing similar institutions. OTS and FDIC oversee a 
number of depository institutions that have been identified as core 
banks because they are subsidiaries of U.S.-based banks that meet the 
asset size and foreign exposure criteria for core banks, and FDIC also 
oversees subsidiaries of foreign-based banks that may adopt the 
advanced approaches. Officials at both agencies said that they are 
active in Basel Committee activities and that they played a role in the 
Federal Reserve and OCC's joint examination of credit risk. In 
addition, according to some of the regulators, all four primary 
regulators have participated in joint examinations of operational risk 
across some of the core banks. 

Regulators Have Taken Some Actions to Reduce Uncertainty but Have Not 
Clarified Which Banks They Will Exempt from the Advanced Approaches: 

Regulators have taken actions to reduce uncertainty by jointly 
providing some clarifying information about certain aspects of the 
capital rules. For example, during the development of the advanced 
approaches rule the regulators issued proposed guidance and interagency 
statements that helped to clarify certain aspects of the rules and, 
beginning in July 2008, updated some of these to reflect the final 
rule. They updated the interagency statement on the qualification 
process that had first been issued in 2005, following the Basel 
Committee's issuance of the New Basel Accord. They also issued updated 
supervisory guidance for Pillar 2 that had been proposed initially in 
February 2007 to provide banks with more detail on the NPR for the 
advanced approaches. Regulators and examiners at one agency said that, 
in their view, it is not necessary to update the guidance on Pillar 1 
that had been issued under the NPR because of the time and care that 
went into crafting the extensive and detailed preamble that accompanied 
the advanced approaches rule. Nonetheless, officials at many of the 
core banks with whom we spoke said that the lack of additional or 
updated guidance, including the standards by which examiners will judge 
the banks' compliance, had been a problem for them. Regulators may 
provide additional joint information to banks and examiners based on 
the questions they have received from banks since the advanced 
approaches rule was issued. Regulators told us they are considering 
providing this information in a question and answer format on their Web 
sites. In addition, each of the regulators will be providing separate 
guidance for its examiners to determine whether the banks they oversee 
are complying with the rule. 

Regulators said they do not intend to issue any joint guidance for the 
proposed standardized approach rule while it is out for comment or when 
a final rule is issued beyond information provided in a preamble. 
However, to ensure that non-core banks are not disadvantaged by core 
banks moving onto the advanced approaches, regulators have said they 
are planning to issue the standardized approach rule before core banks 
move into the first transitional period for the advanced approaches. 
Timely issuance of the final rule and any clarifying information will 
help to ensure that non-core banks have adequate information on which 
to base decisions about which capital regime--advanced approaches, 
standardized approach, or Basel I--will be best for them. 

While some flexibility is necessary and regulators have taken some 
steps to ensure greater consistency in the implementation of the rules, 
there are actions the regulators could take to further reduce banks' 
uncertainty about Basel II without necessarily jeopardizing the safety 
and soundness of the banking system. One area where uncertainty could 
be reduced is in clarifying which core banking institutions would be 
exempt from the application of the advanced approaches rule. The rule 
allows for exempting any core bank---a bank that meets the size or 
foreign exposure criteria for core banks or a depository institution 
that is a core bank because it is a subsidiary of a core bank that 
meets those criteria. Although the rule outlines a mechanism for 
certain banks to be exempted and provides some broad factors regulators 
will use in making these determinations (asset size, level of 
complexity, risk profile, or scope of operation), the regulators have 
not been specific in the current rule about whether they will grant 
these exemptions and under what circumstances. The regulators have said 
that they will not grant many exemptions and did not specify these 
exemptions because they believe it is important for them to retain 
supervisory flexibility as they move forward with implementation of the 
final rule. As such, they said each decision is to be made on a case- 
by-case basis. 

Throughout the development of the rules, regulators had introduced 
uncertainty about the extent to which foreign-based banks with 
subsidiaries that are U.S. bank holding companies will be subject to 
the advanced rules in the United States and the current rule continues 
to provide the Federal Reserve, the regulator of bank holding 
companies, considerable flexibility in making these decisions. The 
Federal Reserve has not answered the question of which specific bank 
holding companies that are subsidiaries of foreign-based banks and 
qualify as U.S. core banks---they have assets of $250 billion or 
greater--will be exempted from using the advanced approaches in the 
United States. When the advanced approaches NPR was issued in 2006, 
some foreign-based institutions with large bank holding companies in 
the United States but relatively small depository institutions were 
surprised to find that they would be treated as core banks in the 
United States. The final rule acknowledged the concerns of those 
institutions and noted that the Federal Reserve may exempt them, but it 
does not make it clear that they will be exempt. Because the Federal 
Reserve, the regulator of bank holding companies, has not issued more 
specific criteria or guidance for reviewing requests for exemptions, 
these banks (at least one bank has requested an exemption) may have to 
devote resources to complying with the U.S. final rule until they 
receive an answer on whether they will be exempted. On the other hand, 
while only one banking organization is affected, the rule specifically 
exempts bank holding companies with significant insurance underwriting 
operations that otherwise would meet the requirements to be a core 
bank. 

Similarly, the rule states that regulators will consider the same 
factors--asset size, level of complexity, risk profile, and scope of 
operations--in making a determination as to whether depository 
institutions that are subsidiaries of U.S. core banks can be exempted. 
As a result, institutions have little guidance concerning the 
likelihood that some of their depository institutions will be exempt 
and will need to prepare for a full implementation of the advanced 
approaches in each entity until they receive a response from their 
regulator on whether they will be exempted. Moreover, because the 
factors are so broad, if different regulators use different specific 
criteria to exempt entities, they may set up the potential for 
regulatory arbitrage. For example, a U.S. banking organization could 
hold higher-risk assets in subsidiary banks that are exempt and remain 
on Basel I and could hold lower-risk assets in subsidiary banks that 
are not exempt from the advanced approaches. And banks that do not 
currently have a structure that would allow them to reduce capital in 
this way could change their structure accordingly by acquiring or 
changing bank charters. The overall result could be lower capital held 
in the bank or resources being devoted to reducing capital that do not 
properly align capital with risk. However, officials from the Federal 
Reserve noted that regardless of the structure of the bank, at the 
holding company level, all material bank assets would be consolidated 
and subject to the advanced approaches rule. 

This continuing uncertainty could make it difficult for banking 
organizations to pursue the most cost-effective route to complying with 
Basel II and could create more risk for the banks at a time when risks 
are already high because of the turmoil in financial markets. For 
example, some industry participants told us that those parts of Basel 
II that do not improve risk management divert resources that banks 
otherwise would use to better manage risk. In addition, resources 
devoted to circumventing certain aspects of the rule through regulatory 
arbitrage will divert the attention of bank officials from improving 
banks' risk-management systems. 

Finally, the uncertainty over which banking institutions ultimately 
will have to adopt the advanced approaches continues because the 
advanced approaches rule says all core banks will be required to adopt 
detailed implementation plans for the complex advanced approaches by 
October 1, 2008, and the proposed standardized approach rule, which 
will not be finalized by that time, contains a question about whether 
and to what extent core banks should be allowed to use the simpler 
proposed standardized approach. The advanced approaches rule generally 
requires core banks to comply with the advanced approaches and adopt an 
implementation plan no later than October 1, 2008. Under this rule, the 
Federal Reserve can exempt bank holding companies from meeting the 
requirements of the final rule for the advanced approaches and primary 
federal regulators can exempt depository institutions that meet the 
definition of a core bank from the advanced approaches requirements. 
Given the authority of the primary federal regulator, once the 
standardized approach rule is finalized, those regulators would be able 
to require that exempt banking organizations adopt that approach. 
However, the proposed standardized approach rule, which will not be 
finalized by the time the core banks must adopt their implementation 
plans, asks whether core banks should be allowed to use the 
standardized approach instead of the advanced approaches. 

In the press release accompanying the proposed standardized approach 
rule, the FDIC Chairman stated, "Given the turbulence in the credit 
markets, I take some comfort with the fixed risk weights established 
under the standardized approach as they provide supervisors with some 
control over unconstrained reductions in risk-based capital." However, 
the interagency statement on U.S. implementation of the advanced 
approaches issued in July 2008, stressed the existing timelines for the 
advanced approaches. The continued discussion on whether core banks 
should be exempt from the advanced approaches and permitted to adopt 
the standardized approach indicates that the primary federal regulators 
continue to have questions about whether the advanced approaches are 
the best risk-based capital requirements for core banks. Thus, it is 
difficult to tell whether the regulators have found a solution to 
difficulties that resulted from the differing perspectives they brought 
to negotiations during the development of the advanced approaches. We 
recommended in our February 2007 report on Basel II that regulators 
take actions to jointly specify the criteria they will use to judge the 
attainment of their goals for Basel II implementation and for 
determining its effectiveness for regulatory capital-setting purposes. 
We noted that without clarification on the criteria to evaluate or make 
changes in the Basel II rules, the implementation will continue to 
generate questions about the adequacy of the framework. 

Plans for Studying the Competitive Impacts of the Final Rules Have Not 
Been Fully Developed: 

The regulators have not fully developed plans for an interagency study 
that is to assess implementation and provide the information to form 
the basis for allowing banks to fully transition to Basel II. Partly in 
response to recommendations we made in 2007, the final rule says that 
the regulators will issue annual reports during the transitional period 
and conduct a study of the advanced approaches after the second 
transitional period. According to the rule, the annual reports are to 
provide timely and relevant information on the implementation of the 
advanced approaches. The interagency study is to be conducted to 
determine if there are material deficiencies in the advanced approaches 
and whether banks will be permitted to fully transition to Basel II. In 
its regulatory impact analysis, OCC said that the regulators will 
consider any egregious competitive effects associated with 
implementation of Basel II, whether domestic or international in 
context, to be a material deficiency. 

Among the items the rule specifies that the study will cover, several 
are important first steps in studying the competitive effects of the 
rule. These include: 

* the level of minimum required regulatory capital under U.S. advanced 
approaches compared to the capital required by other international and 
domestic regulatory capital standards; 

* comparisons among peer core banks of minimum regulatory capital 
requirements; 

* the processes banks use to develop and assess risk parameters and 
advanced systems, and supervisory assessments of their accuracy and 
reliability; and: 

* changes in portfolio composition or business mix.[Footnote 40] 

Some of these steps are similar to the calculations the regulators 
performed as part of QIS-4. The advantage of the future study over QIS- 
4 is that it will be based on actual data provided by banks whose risk 
management and data systems have been reviewed by regulators as part of 
the approval process for banks to enter the first two transitional 
periods. In addition, one regulator noted that the study will also 
benefit from the stresses of the recent market turmoil. This study 
should allow the regulators to determine the extent to which total 
regulatory capital changes in the short run, the specific behavior in 
which banks engage to comply with some aspects of the rule, and how the 
rule affects the capital of different banks. 

However, plans for the study do not address a number of factors 
including the establishment of shared overall goals and criteria for 
Basel II that will help delineate the study's scope, methodology, and 
timing. For example, while OCC in its impact study said that the 
evaluation of competitive impacts will be an important part of the 
study, the rule does not specify how this will be measured and the 
scope and methodology of the study are not clearly designed to achieve 
this objective. Because regulators design the study to evaluate Basel 
II in light of clearly specified overall objectives or criteria for 
Basel II, it will be difficult to jointly determine the extent to which 
the rules need to be modified or whether implementation of Basel II 
should proceed. If some regulators object to the full implementation of 
Basel II while others do not, the rule specifies that a regulator can 
permit the banking organizations for which it is the primary federal 
regulator to move forward with the advanced approaches if it first 
provides a public report explaining its reasoning. However, such an 
outcome would not provide confidence in the current regulatory system 
and could allow for regulatory arbitrage. 

Further, the scope of the study has not been well defined. While the 
study contemplates calculations of capital using the standardized 
approach, Basel I, and other international rules as well as the actual 
data on the banks following the advanced approaches, regulators have 
not said that they plan to collect comparable data on financial 
entities not adopting these approaches--specifically, those banking 
institutions that will adopt the standardized approach or remain on 
Basel I. In addition, the regulators have not explicitly included the 
CSEs in the study. The effectiveness of the study will be limited if 
the CSEs are not included because information on a major segment of 
competitors of core banks that has had significant experience with some 
aspects of the advanced approaches will have been excluded. The 
agreement signed on July 7, 2008, between the Federal Reserve and SEC 
regarding coordination and information sharing in areas of common 
regulatory interest should facilitate the inclusion of the CSEs in any 
study of the advanced approaches. Finally, the regulators have 
conducted little research on international differences that could have 
competitive effects in the past, and the study's design does not 
explicitly include research on international differences that could 
have competitive effects. However, since U.S. regulators participate in 
the Capital Monitoring Group, Accord Implementation Group, and other 
similar groups, they will have some perspective on Basel II 
implementation in the other countries in that group including some 
European Union countries and Canada that they will be able to use for 
this purpose. OCC officials explained that the Capital Monitoring Group 
will collect and analyze information on the implementation of Basel II 
in other countries and suggested that this information will inform the 
U.S. study. In addition, some U.S. regulators noted that the study 
outlined in the rule will not preclude them from looking at a broad 
range of data. 

The methodology the study will use to evaluate competitive impacts 
initially is not fully developed, although from a methodological 
perspective Basel II affords an opportunity to consider the impacts of 
regulatory capital on bank behaviors and among groups of banks adopting 
different requirements at different times. While the measurements and 
comparisons envisioned for the study are a necessary first step for 
evaluating competitive impacts among the core banks and between the 
core banks and other groups, they do not take full advantage of the 
opportunities to better understand the impact of regulatory capital on 
a range of bank behavior. Because banks in the United States and around 
the world are adopting a range of capital requirements at different 
times, Basel II affords a unique opportunity to consider whether event 
studies could contribute to a better understanding of the impact of 
regulatory capital on a variety of bank behaviors. While regulators at 
OCC noted that with banks on different capital regimes, academics and 
other researchers, including those at the regulatory agencies, will 
have data available to study the impact of regulatory capital on bank 
behavior, they said that they had not thoroughly considered the use of 
event studies as part of the study planned by the regulators. Because 
regulators have not clearly specified how they will evaluate the 
competitive impacts of Basel II, there is an increased likelihood that 
the kinds of data needed to complete an effective study will not be 
available. 

In addition, the advanced approaches rule does not specify a 
methodology for the study to analyze the extent to which the new rules 
provide opportunities for regulatory arbitrage that could limit the 
effectiveness of the rules in promoting improved risk management 
throughout the banking system. Several industry participants noted that 
having multiple capital requirements with different levels of risk 
sensitivity provides incentives for core banks to hold less risky 
assets and leave more risky assets in banks using the standardized 
approach or Basel I. Higher risk-based capital requirements for high- 
risk assets at core banks may increase their cost of holding these 
assets. Greater costs would reduce the supply of credit for these types 
of loans, and thus returns would increase. As a result, banks with less 
risk-sensitive capital requirements under Basel I or the standardized 
approach might find some higher risk credits more attractive at these 
higher rates of return. (As illustrated earlier in fig. 2, there may be 
different amounts of capital required for the same asset across the 
different risk-based rules.) Officials at one regulatory agency said 
that all of the regulators were aware of this potential outcome and 
planned to look at changes in the portfolios of core banks in the 
study. Further, for non-core banks, regulators at another agency said 
they would become aware of non-core banks increasing their holdings of 
high-risk assets through their normal oversight duties. However, the 
advanced approaches rule does not specify how the study would more 
fully explore this potentially important outcome of the new rules. If 
this arbitrage took place, the rules could require less capital overall 
in the banking system and would leave banks with the least well- 
developed risk management systems with the riskiest assets, thus 
exposing the U.S. banking system to greater systemic risk. 

Finally, the timing of the study is unclear. The rule specifies that 
the study will be published after the second transitional period, but 
core banks could begin the four intermediate phases required for full 
implementation in 2008, 2009, or 2010 and different banks (as well as 
different types of banks) could enter the second transitional period in 
different years. The phased implementation produces uncertainty about 
timing and could throw into question how many banks will be included in 
the study, and whether the results of the study will provide relevant 
information for all of the banks. For example, if the banks in the 
second transitional period in 2011 are primarily retail banks, the 
results are not likely to be applicable for the custodial banks, or 
vice versa. As a result of this and other factors discussed, the use of 
the study for taking actions that would improve risk management or 
reduce competitive concerns may be limited. 

Some regulators told us that they have not yet focused on plans for the 
study, in part, because it is early in the Basel II implementation 
process and they and the banks they supervise have been dealing with 
the financial turmoil. In addition, some regulators said that the 
language and factors laid out in the final rule should be viewed as a 
starting point, and officials at one regulatory agency said that the 
study will benefit from the data that will be available from the 
financial turmoil in the world's credit markets. 

Conclusions: 

A global effort is underway to implement the New Basel Accord, which 
aims to improve the risk-management practices of banks, in part, by 
aligning the capital banks hold more closely with the risks they face. 
Capital's role becomes more important in periods of economic 
uncertainty because banks rely on capital to weather unexpected losses. 
Although the impact of regulatory capital on a bank's ability to 
compete is not always obvious because banks often hold more than their 
minimum required capital, regulatory capital is one of many factors 
that affects competition. And, the adoption of Basel II in the United 
States has raised concerns about competitive effects it could have on 
banks of varying sizes and in various locations. In addition, 
regulators have made clear that in light of the current market turmoil 
further revisions will be made in Basel II. 

Uncertainty about how to implement Basel II, to whom the rules will 
apply, and the effects the rules will have may lead banks to devote 
resources to information gathering and implementation that could 
otherwise be dedicated to improving risk management or other purposes. 
In our 2007 report, we noted that the rulemaking process for Basel II 
could benefit from increased transparency to respond to broader 
questions and concerns about transitioning to Basel II in the United 
States. The regulators referred to the recommendation in the advanced 
approaches rule and, with that rule and the proposed standardized 
approach rule, they have provided greater clarity about some aspects of 
Basel II. We recognize that the time table for Basel II implementation 
in the United States has slowed since we issued our earlier report and 
that both the regulators and the banks have been dealing with the 
market turmoil that began in mid-2007. This gradual implementation is 
allowing bank regulators to reassess banks' risk-management systems and 
consider changes in the rules before any banks begin their Basel II 
implementation. As part of this preparation period, regulators have 
taken and are planning some actions to reduce uncertainty, but could 
take further actions to address remaining uncertainties about the 
implementation of the rules and facilitate banks' planning and 
preparation for their implementation of a new capital regime. 

Regulators have taken actions to reduce some of the uncertainty 
surrounding implementation of Basel II by providing information to aid 
examiners and banks in interpreting the rules. Regulators have updated 
some publicly available information on the process they will use to 
qualify banks for the advanced approaches and examine them under Pillar 
2. Regulators have also engaged in discussions among themselves 
concerning posting additional information in a question and answer 
format on their Web sites. The timely issuance of additional 
information on the advanced approaches and a final standardized 
approach rule, which is in process, will enable banks to best prepare 
to meet the new risk-based capital requirements and will help to ensure 
regulatory consistency across the banks. As a result, we encourage the 
regulators to continue providing joint information in a timely manner 
on both the advanced and standardized approaches. 

We recognize that regulators have taken steps to reduce some 
uncertainties related to Basel II; however, the regulators could take 
additional steps to address uncertainties that are not related to their 
need for flexibility to respond to innovation in the industry and to 
unintended consequences that the rules may have. For example, in the 
final rule, the regulators did not specify which banks technically met 
the definition of core banks. Although, the rule specifically says that 
certain banks may be exempted by their primary regulator from the 
advanced approaches requirements, it does not provide well-defined 
criteria for evaluating requests for exemptions. Because this clarity 
has not been provided and specific criteria have not been laid out, 
regulators may not provide exemptions in a consistent manner. The 
issuance of more specific guidance on which banks will be exempt from 
applying the advanced approaches would provide clarity and enable banks 
to plan accordingly. Also, the question in the NPR for the standardized 
approach about whether core banks should be able to use the proposed 
standardized approach indicates that the primary federal regulators 
continue to have questions about whether the advanced approaches are 
the best risk-based capital requirements for core banks. Regulatory 
differences on these issues can lead to increased costs for the banks, 
inefficiencies for their regulators, and may weaken the overall 
effectiveness of the regulatory system by creating opportunities for 
banks to engage in regulatory arbitrage. 

In our 2007 report, we recommended that regulators issue public reports 
on the progress and results of implementation efforts and that this 
reporting should include an articulation of the criteria by which they 
would assess the success of Basel II. While the regulators have 
proposed a study of the core banks after the second transitional year 
of the implementation of the advanced approaches, they have not yet 
developed the criteria on which to base the study's design and 
objectives. These are needed for a determination of whether Basel II is 
effective for regulatory capital-setting purposes and whether to 
ultimately allow banks to move past the third transitional period to 
full Basel II implementation. As delineated in the advanced approaches 
rule, the study will measure the changes in capital and portfolios held 
by the core banks and will look at the differences in required capital 
for these banks if they were under the standardized approach rule or 
Basel I---necessary steps for evaluating the competitive impact of 
Basel II--but it does not explicitly describe components needed to 
determine if there are material deficiencies in the rule or for 
regulators to reach agreement on whether banks should be permitted to 
fully implement the advanced approaches. However, the gradual 
implementation of the advanced approaches in the United States affords 
regulators time to jointly establish criteria for evaluating Basel II 
and to fully develop a study that flows from those criteria--including 
(1) a broad enough scope--inclusion of non-core banks, CSEs, and 
foreign-based banks--to capture competitive effects; (2) consideration 
of a number of methodologies; and (3) the resolution of the timing 
issue. Such actions would help the regulators make better-informed 
decisions on an interagency basis about whether changes to the rules 
were necessary and whether to permit banks to fully implement Basel II. 
Without these criteria, it will be difficult for regulators to make 
these judgments and provide consistent guidance for banks. 

Recommendations for Executive Action: 

We are making two recommendations to the heads of the FDIC, Federal 
Reserve, OCC, and OTS: 

To further limit any potential negative effects, where possible, 
regulators should move to minimize the uncertainty surrounding certain 
aspects of Basel II. Specifically, regulators should clarify how they 
will use certain regulatory flexibility under the advanced approaches 
rule, particularly with regard to how they will exercise exemptions for 
core banks from the advanced approaches requirement and the extent to 
which core banks will be allowed to adopt the standardized approach. 

To improve the understanding of potential competitive effects of the 
new capital framework, the regulators should take steps jointly to plan 
for the study to determine if major changes need to be made to the 
advanced approaches or whether banks will be able to fully implement 
the current rule. In their planning, they should consider such issues 
as the objectives, scope, methodology, and timing needs for the future 
evaluation of Basel II. The plan should include how the regulators will 
evaluate competitive differences between core and non-core banks in the 
United States, between core banks and CSEs, and between U.S.-based 
banks and banks based in other countries. 

Agency Comments and Our Evaluation: 

We provided the heads of the Federal Reserve, FDIC, OCC, OTS, SEC, and 
Department of the Treasury with a draft of this report for their review 
and comment. We received written comments from the banking regulators 
in a joint letter. These comments are summarized below and reprinted in 
appendix IV. The banking regulators also provided technical comments 
that we incorporated in the report where appropriate. We did not 
receive comments from SEC or the Department of the Treasury. 

In their letter, the banking regulators strongly endorsed our opening 
statement that ensuring that banks maintain adequate capital is 
essential to the safety and soundness of the banking system and said 
that it is this overarching objective that will guide their efforts and 
has led them to include additional prudential safeguards in their 
implementation of the Basel II rules. In a somewhat related matter, the 
regulators said that the report emphasizes the cost to banks of holding 
capital but did not discuss how a bank's strong capital base confers 
competitive strength and create strategic opportunities. While we 
describe some of the costs to banks of holding additional capital 
because this is an important channel through which the new capital 
rules could affect the competitiveness of U.S. banking organizations, 
we also note that more capital reassures creditors and reduces the cost 
of borrowing. In addition, as noted in the draft, banks hold capital 
for this and other reasons including the ability to take advantage of 
strategic opportunities such as acquiring other banking institutions. 

As we detailed in the draft, the banking regulators highlighted the 
actions they have taken to address many of the concerns that bankers 
and others have raised about the potential competitive equity effects 
of the implementation of Basel II and said that they are in general 
agreement with our recommendations. Specifically, they said that they 
will work together to resolve, at the earliest possible time, the 
question posed for comment in the proposed standardized approach rule 
regarding whether and to what extent core banks should be able to use 
the standardized approach. With regard to clarifying how they will 
decide whether to grant requests from core banks to be exempt from the 
requirement to adopt the advanced approaches, the regulators said they 
will assess each exemption request in light of the specific facts and 
circumstances applicable to the institution seeking the exemption and 
that they have already commenced discussions to ensure a clear and 
consistent interpretation of these provisions is conveyed to U.S. 
banks. 

Regarding the need to jointly plan the required study, the regulators 
commented that they will work together to develop "plans for the 
required study of the impact of the advanced approaches of Basel II." 
Specifically, they said that they will begin to develop more formal 
plans for the study once they had "a firmer picture of banks' 
implementation plans" but noted the difficulties concerning drawing 
definitive conclusions about the effects of changes in regulatory 
capital rules. They also said that they would consider including in 
their analysis the potential competitive effects with CSEs and foreign 
banks as we recommended. While we are encouraged by the regulators' 
recognition of the need for more formal plans and consideration of the 
scope of the study to include CSEs and foreign banks, we noted a number 
of additional factors that also should be considered, such as 
developing criteria that will help them determine whether there are 
material deficiencies that can be attributed to the new rules and what 
changes, if any, could address those deficiencies. Finally, because 
Basel II affords an opportunity to consider the impacts of regulatory 
capital on bank behaviors and among groups of banks adopting different 
requirements at different times, we noted in the draft that it is 
important that regulators consider a number of methodologies for 
evaluating the new capital rules and potential competitive effects to 
determine which are the most appropriate. 

As agreed with your offices, unless you publicly release its contents 
earlier, we plan no further distribution of this report until 30 days 
from its date of issue. At that time we will send copies of this report 
to interested congressional committees, the Chairman of the Board of 
Governors of the Federal Reserve System, Chairman of the Federal 
Deposit Insurance Corporation, the Comptroller of the Currency, the 
Director of the Office of Thrift Supervision, the Chairman of the 
Securities and Exchange Commission, and the Secretary of the Treasury. 
We will also make copies available to others on request. In addition, 
the report will be available at no charge on GAO's Web site at 
[hyperlink, http://www.gao.gov].

Appendix I: Objectives, Scope, and Methodology: 

Our objectives in this report were to discuss (1) the nature of the 
competitive environment in which U.S. banking organizations compete, 
(2) the extent to which different capital requirements may have 
competitive impacts on U.S. banking organizations internationally and 
domestically, and (3) actions regulators could take to address 
competitive effects and other potential negative effects of the new 
capital rules during implementation. 

For all our objectives, we reviewed a variety of documents, including 
regulators' statements; the international Basel II framework (entitled 
"International Convergence of Capital Measurement and Capital 
Standards: A Revised Framework") and other documents from the Basel 
Committee, such as the 1988 Basel Capital Accord (Basel I); the Basel 
II, Basel 1A, and Standardized Approach Notices of Proposed Rulemaking 
(NPR) and the final rule on the advanced approaches; supervisory 
guidance; academic articles, and our previous reports on banking 
regulation.[Footnote 41] We interviewed senior supervisory officials at 
the Board of Governors of the Federal Reserve System and Federal 
Reserve Banks of Boston, New York, and Richmond (Federal Reserve), 
Office of Management and Budget, Office of the Comptroller of the 
Currency (OCC), Federal Deposit Insurance Corporation (FDIC), Office of 
Thrift Supervision (OTS), Securities and Exchange Commission, and 
Department of the Treasury. We also interviewed officials from the 
Accord Implementation Group, several foreign banking regulatory 
agencies, domestic, international, and foreign trade associations, 
credit rating agencies, and several academics and consultants with 
banking expertise. In addition, we interviewed officials from all of 
the core banks and other banks, both foreign and domestic, with 
operations in the United States. Finally, we attended several 
conferences held by regulators and trade associations that included 
discussions related to Basel II. 

To describe the competitive environment in which U.S. banks operate, we 
collected data from several sources to illustrate which types and sizes 
of banks are active in which kinds of products. We used data from the 
Federal Reserve's Structure and Share Data for U.S. Banking Offices of 
Foreign Entities, and Consolidated Financial Statements for Bank 
Holding Companies (i.e., FR Y-9C). These data include the amount of 
assets in particular products that bank holding companies hold on and 
off of their balance sheets. For banks and thrifts that do not report 
assets in particular products at the consolidated level to their 
regulator, we used data on banks and thrifts in the Federal Financial 
Institutions Examination Council's (FFIEC) Consolidated Reports of 
Condition and Income (FFIEC 031 or Call Report) and OTS's Thrift 
Financial Reports, respectively. We also used data from FFIEC's Country 
Exposure Lending Survey. 

To compare activities across banks of different sizes, we used data at 
the consolidated level because banks generally compete on an 
enterprisewide basis. For bank holding companies, we used data provided 
by the Federal Reserve. Almost all bank holding companies that have 
assets greater than $500 million report assets in particular product 
categories on a consolidated basis to the Federal Reserve using the Y- 
9C form; however, a large proportion of those with assets under $500 
million about 80 percent of the bank holding companies and a few larger 
bank holding companies do not report consolidated assets on a product 
basis to the Federal Reserve. We included these bank holding companies 
that have few assets outside their chartered commercial banks in our 
analysis, by having staff at the Federal Reserve group the commercial 
banks by bank holding company and sum the assets reported in the Call 
Reports accordingly. Thrift holding companies do not report data on 
assets by product category to OTS on a consolidated basis. Because 
thrift holding companies are often engaged in a wide variety of 
activities outside of banking, we could not rely on the thrift 
financial report data on individual thrifts to approximate the holding 
company for some thrifts as we did in the case of some bank holding 
companies. However, we were able to have OTS staff provide thrift 
financial report data that we used to approximate the thrift holding 
companies for those thrift companies primarily in banking. We did this 
by having OTS staff group the thrifts by holding company for those 
where thrifts make up 95 percent of the assets of the holding company 
and where they make up 75 percent of the assets of the holding company. 
The allocation of assets across product lines was substantially the 
same for these two categories, which allowed us to conclude that the 
data gave us a good approximation of differences between thrift holding 
companies that are primarily in the business of banking and bank 
holding companies. We concluded that they do differ in that thrifts 
that are engaged primarily in the business of banking hold a much 
larger percentage of their assets-in residential mortgages than do bank 
holding companies across all size categories. To assess the reliability 
of these data, we talked with knowledgeable agency officials about the 
data and tested the data to identify obvious problems with completeness 
or accuracy. We determined the data were sufficiently reliable for the 
purposes of this report. 

To determine the extent to which different capital requirements may 
impact how various U.S. banking organizations compete, we reviewed the 
available academic literature on the role capital plays in bank 
competition. We also estimated minimum required capital for some assets 
under the advanced and standardized approaches for credit risk, Basel 
I, and leverage requirements, based on available information and data 
from the U.S. federal banking regulators' fourth quantitative impact 
study (QIS-4) and Moody's Investors Service. There are some limitations 
associated with the data from QIS-4. At the time, the regulators 
emphasized that QIS-4 was conducted on a "best efforts" basis without 
the benefit of either a definitive set of proposals or meaningful 
supervisory review of the institutions' systems. We assessed the 
reliability of the data we used and found that, despite limitations, 
they were sufficiently reliable for our purposes. 

We conducted this performance audit from May 2007 to September 2008 in 
Amsterdam, The Netherlands; Brussels, Belgium; Boston, Massachusetts; 
Chicago, Illinois; and Charlotte, North Carolina; London, United 
Kingdom; New York, New York; Toronto, Canada; and Washington, D.C., in 
accordance with generally accepted government auditing standards. Those 
standards require that we plan and perform the audit to obtain 
sufficient, appropriate evidence to provide a reasonable basis for our 
findings and conclusions based on our audit objectives. We believe that 
the evidence obtained provides a reasonable basis for our findings and 
conclusions based on our audit objectives.

Appendix II: Three Pillars of the Advanced Approaches: 

Pillar 1: Minimum Capital Requirements: 

Pillar 1 of the advanced approaches rule features explicit minimum 
capital requirements, designed to ensure bank solvency by providing a 
prudent level of capital against unexpected losses for credit, 
operational, and market risk. The advanced approaches, which are the 
only measurement approaches available to and required for core banks in 
the United States, will make capital requirements depend in part on a 
bank's own assessment, based on historical data, of the risks to which 
it is exposed. 

Credit Risk: 

Under the advanced internal ratings-based (A-IRB) approach, banks must 
establish risk rating and segmentation systems to distinguish risk 
levels of their wholesale (most exposures to companies and governments) 
and retail (most exposures to individuals and small businesses) 
exposures, respectively. Banks use the results of these rating systems 
to estimate several risk parameters that are inputs to supervisory 
formulas. Figure 7 illustrates how credit risk will be calculated under 
the Basel II A-IRB. Banks must first classify their assets into 
exposure categories and subcategories defined by regulators: for 
wholesale exposures those subcategories are high-volatility commercial 
real estate and other wholesale; for retail exposures those 
subcategories are residential mortgages, qualifying revolving exposures 
(e.g., credit cards), and other retail. Banks then estimate the 
following risk parameters, or inputs: the probability a credit exposure 
will default (probability of default or PD), the expected size of the 
exposure at the time of default (exposure at default or EAD), economic 
losses in the event of default (loss given default or LGD) in 
"downturn" (recession) conditions, and, for wholesale exposures, the 
maturity of the exposure (M). In order to estimate these inputs, banks 
must have systems for classifying and rating their exposures as well as 
a data management and maintenance system. The conceptual foundation of 
this process is that a statistical approach, based on historical data, 
will provide a more appropriate measure of risk and capital than a 
simple categorization of asset types, which does not differentiate 
precisely between risks. Regulators provide a formula for each exposure 
category that determines the required capital on the basis of these 
inputs. If all the assumptions in the supervisory formula were correct, 
the resulting capital requirement would exceed a bank's credit losses 
in a given year with 99.9 percent probability. That is, credit losses 
at the bank would exceed the capital requirement with a 1 in 1,000 
chance in a given year, which could result in insolvency if the bank 
only held capital equal to the minimum requirement. 

Figure 7: Computation of Wholesale and Retail Capital Requirements 
under the Advanced Internal Ratings-based Approach for Credit Risk: 

This figure is an illustration showing the computation of wholesale and 
retail capital requirements under the advanced internal ratings-based 
approach for credit risk. 

[See PDF for image] 

Source: GAO analysis of information from the advanced approaches rule. 

Notes: This figure focuses on wholesale and retail nondefaulted 
exposures, an important component of the total credit risk calculation. 
The total credit risk capital requirement also covers defaulted 
wholesale and retail exposures, as well as risk from securitizations 
and equity exposures. A bank's qualifying capital is also adjusted, 
depending on whether its eligible credit reserves exceed or fall below 
its expected credit losses. 

[End of figure] 

Banks may incorporate some credit risk mitigation, including 
guarantees, collateral, or derivatives, into their estimates of PD or 
LGD to reflect their efforts to hedge against unexpected losses. 

Operational Risk: 

To determine minimum required capital for operational risk, banks will 
use their own quantitative models of operational risk that incorporate 
elements required in the advanced approaches rule. To qualify to use 
the advanced measurement approaches (AMA) for operational risk, a bank 
must have operational risk management processes, data and assessment 
systems, and quantification systems. The elements that banks must 
incorporate into their operational risk data and assessment system are 
internal operational loss event data, external operational loss event 
data, results of scenario analysis, and assessments of the bank's 
business environment and internal controls. Banks meeting the AMA 
qualifying criteria would use their internal operational risk 
quantification system to calculate the risk-based capital requirement 
for operational risk, subject to a solvency standard specified by 
regulators, to produce a capital buffer for operational risk designed 
to be exceeded only once in a thousand years. 

Market Risk: 

Regulators have allowed certain banks to use their internal models to 
determine required capital for market risk since 1996 (known as the 
market risk amendment or MRA). Under the MRA, a bank's internal models 
are used to estimate the 99th percentile of the bank's market risk loss 
distribution over a 10-business-day horizon, in other words a solvency 
standard designed to exceed trading losses for 99 out of 100 10- 
business-day intervals. The bank's market risk capital requirement is 
based on this estimate, generally multiplied by a factor of three. The 
agencies implemented this multiplication factor to provide a prudential 
buffer for market volatility and modeling error. The OCC, Federal 
Reserve, and FDIC are proposing to incorporate their existing market 
risk rules and are proposing modifications to the market risk rules, to 
include modifications to the MRA developed by the Basel Committee, in a 
separate NPR issued concurrently with the proposal for credit and 
operational risk. OTS is proposing its own market risk rule, including 
the proposed modifications, as a part of that separate NPR. 

In previous work, regulatory officials generally said that changes to 
the rules for determining capital adequacy for market risk were 
relatively modest and not a significant overhaul. The regulators have 
described the objectives of the new market risk rule as including 
enhancing the sensitivity of required capital to risks not adequately 
captured in the current methodologies of the rule and enhancing the 
modeling requirements consistent with advances in risk management since 
the implementation of the MRA. In particular, the rule contains an 
incremental default risk capital requirement to reflect the growth in 
traded credit products, such as credit default swaps, that carry some 
default risk as well as market risk. 

Pillar 2: Supervisory Review: 

The Pillar 2 framework for supervisory review is intended to ensure 
that banks have adequate capital to support all risks, including those 
not addressed in Pillar 1, and to encourage banks to develop and use 
better risk management practices. Banks adopting Basel II must have a 
rigorous process of assessing capital adequacy that includes strong 
board and senior management oversight, comprehensive assessment of 
risks, rigorous stress testing and validation programs, and independent 
review and oversight. In addition, Pillar 2 requires supervisors to 
review and evaluate banks' internal capital adequacy assessments and 
monitor compliance with regulatory capital requirements. Under Pillar 
2, supervisors must conduct initial and ongoing qualification of banks 
for compliance with minimum capital calculations and disclosure 
requirements. Regulators must evaluate banks against established 
criteria for their (1) risk rating and segmentation system, (2) 
quantification process, (3) ongoing validation, (4) data management and 
maintenance, and (5) oversight and control mechanisms. Regulators are 
to assess a bank's implementation plan, planning and governance 
process, and parallel run performance. Under Pillar 2, regulators 
should also assess and address risks not captured by Pillar 1 such as 
credit concentration risk, interest rate risk, and liquidity risk. 

Pillar 3: Market Discipline in the Form of Increased Disclosure: 

Pillar 3 is designed to encourage market discipline by requiring banks 
to disclose additional information and allowing market participants to 
more fully evaluate the institutions' risk profiles and capital 
adequacy. Such disclosure is particularly appropriate given that Pillar 
I allows banks more discretion in determining capital requirements 
through greater reliance on internal methodologies. Banks would be 
required to publicly disclose both quantitative and qualitative 
information on a quarterly and annual basis, respectively. For example, 
such information would include a bank's risk-based capital ratios and 
their capital components, aggregated information underlying the 
calculation of their risk-weighted assets, and the bank's risk 
assessment processes. In addition, federal regulators will collect, on 
a confidential basis, more detailed data supporting the capital 
calculations. Federal regulators would use this additional data, among 
other purposes, to assess the reasonableness and accuracy of a bank's 
minimum capital requirements and to understand the causes behind 
changes in a bank's risk-based capital requirements. Federal regulators 
have developed detailed reporting schedules to collect both public and 
confidential disclosure information.

Appendix IV Comments from Federal Banking Regulators: 

Office of the Comptroller of the Currency: 
Board of Governors of the Federal Reserve System: 
Federal Deposit Insurance Corporation: 
Office of Thrift Supervision: 

September 3, 2008: 

Ms. Orice M. Williams: 
Director, Financial Markets and Community Investment: 
United States Government Accountability Office: 
Washington, D.C. 20548: 

Dear Ms. Williams: 

The Federal Reserve Board (FRB), Federal Deposit Insurance Corporation 
(FDIC), Office of the Comptroller of the Currency (OCC), and the Office 
of Thrift Supervision (OTS) (collectively, the "Agencies") have 
received and reviewed your draft report titled, "New Basel II Rules 
Reduced Certain Competitive Concerns, but Bank Regulators Should 
Address Remaining Uncertainties." This joint response summarizes the 
Agencies' overall reaction to the draft report. Additional technical 
comments have been provided separately by staff of each of the 
Agencies. 

In the draft report, the GAO concluded that the Agencies have addressed 
some of the earlier competitive concerns of banks. The report also 
describes bankers' concerns about regulatory constraints on their 
ability to reduce their capital requirements, and their concerns about 
lingering uncertainty regarding key aspects of the rule. The report 
recommends that U.S. bank regulators (1) clarify how they will use the 
flexibility built into the rules, and (2) fully develop plans, on a 
joint basis, for the study of the impacts of Basel II the Agencies have 
committed to undertake. 

The first sentence of the report states, "Ensuring that banks maintain 
adequate capital is essential to the safety-and-soundness of the 
banking system." The Agencies strongly endorse this statement. The 
ultimate objective of our capital rules is to promote the overall 
safety and soundness of U.S. banking institutions. It is this 
overarching objective that will guide our efforts and has led us to 
include additional prudential safeguards in our implementation of the 
Basel II rules. 

While the report emphasizes the cost to banks of holding capital, an 
important issue that is not discussed is how a bank's strong capital 
base confers competitive strength. For example, by defusing concerns 
about a bank's ability to absorb losses, strong capital can help 
preserve a bank's access to funding on competitive terms. And as we 
have seen during this period of economic adversity, strongly 
capitalized institutions are more likely to have the financial 
flexibility to expand lending when other institutions falter. 

We are pleased that the GAO acknowledges actions that the Agencies have 
taken to address many of the concerns that bankers and others have 
raised about the potential competitive equity effects of the 
implementation of Basel II. Specifically, as acknowledged by the 
report, the Agencies have: 

* Eliminated many of the prior differences between the U.S. advanced 
approaches rule and the Basel II mid-year text. These changes will help 
reduce compliance costs and competitive concerns for internationally 
active institutions. 

* Proposed a standardized approach that is more consistent with the 
international Basel II Framework than was the Agencies' earlier "Basel 
IA" proposal. 

* Actively worked together and with regulators across the world to 
coordinate our reviews of banks' implementation plans and risk models 
and share information. As core banks reported to the GAO, these actions 
have "been helpful in addressing potential negative impacts for U.S. 
firms" and "limited the compliance costs of subsidiaries of U.S. banks 
operating abroad." 

* Established processes to coordinate implementation of the new rules 
across charter types. 

* Developed joint guidance, issued in July 2008, on the qualification 
process the Agencies will use for advanced approaches institutions. 

The Agencies are in general agreement with the recommendations 
contained in the report. The Agencies will work together to attempt to 
resolve, at the earliest possible time, the question posed for comment 
in the proposed rule on the standardized approach, on whether or to 
what extent core banks should be able to use the standardized approach. 
Of course, any potential change to current requirements for core banks 
in this regard would require revisions to the advanced approaches rule. 
Under existing requirements, core banks are expected to comply with the 
advanced approaches rule. 

With regard to clarifying how the Agencies will decide whether to grant 
requests from core banks to be exempt from the requirement to adopt the 
advanced approaches, the rule lists the factors the Agencies will 
consider. The Agencies will assess each exemption request in light of 
the specific facts and circumstances applicable to the institution 
seeking the exemption. The Agencies have already commenced discussions 
to ensure a clear and consistent interpretation of these provisions is 
conveyed to U.S. banks. 

The Agencies also will work together to develop plans for the required 
study of the impact of the advanced approaches of Basel II. As the 
report correctly notes, our regulatory capital priorities to date have 
been to: a) take actions to reduce/mitigate potential competitive 
effects of our Basel II-related proposals; b) respond to current market 
disruptions, including making enhancements to the advanced approaches 
framework; c) provide guidance and discuss implementation plans and 
issues with core banks; and d) finalize the standardized approach rule. 
We will begin to formulate more formal plans for the study after we 
have a firmer picture of banks' implementation plans. In formulating 
our plans, we will consider the GAO's recommendations to include in our 
analysis the potential competitive effects with Consolidated Supervised 
Entities and foreign banks. We would caution that the fundamental 
shifts occurring across the financial industry in light of the recent 
market disruptions — both in terms of individual firm and aggregate 
industry risk profiles — will accentuate the difficulties the GAO has 
noted in drawing definitive conclusions about the effects of changes in 
regulatory capital rules. 

We appreciate the professionalism of the GAO review team that prepared 
the report. Thank you for the opportunity to comment on the draft.

[1] In this report, the term bank generally refers to depository 
institutions (commercial banks and thrifts) as well as bank holding 
companies. Where the distinction is significant, we refer to bank 
holding companies as the depository institution's ultimate U.S. holding 
company. Since thrift holding companies are not subject to Basel 
capital requirements, they are not included in the term bank in this 
report.

[9] Credit risk is the potential for loss resulting from the failure of 
a borrower or counterparty to perform on an obligation. Operational 
risk is the risk of loss resulting from inadequate or failed internal 
processes, people, and systems or from external events. 

[10] Market risk is the potential for loss resulting from movements in 
market prices, including interest rates, commodity prices, stock 
prices, and foreign exchange rates. Regulators have allowed certain 
banks to use their internal models to determine required capital for 
market risk since 1996 (known as the market risk amendment or MRA). 
Generally, under the MRA, a bank's internal models are used to estimate 
the 99th percentile of the bank's market risk loss distribution over a 
10-business-day horizon, in other words a solvency standard designed to 
exceed trading losses for 99 out of 100 10-business-day intervals. 

[11] 72 Fed. Reg. 69288 (Dec. 7, 2007). 

[12] The four phases are (1) the parallel run--four consecutive 
quarters in which a bank meets the qualification requirements and is 
subject to the Basel I rules but simultaneously calculates its risk- 
based capital ratios under the advanced approaches; (2) the first 
transitional period--a period of at least four consecutive quarters in 
which the bank computes its risk-based capital ratios using the Basel I 
rule and the advanced approaches rule, and required risk-based capital 
must be at least 95 percent of the Basel I requirement; (3) the second 
transitional period--a period of at least four consecutive quarters in 
which the bank computes its risk-based capital ratios using the Basel I 
rule and the advanced approaches rule, and required risk-based capital 
must be at least 90 percent of the Basel I requirement; and (4) the 
third transitional period--a period of at least four consecutive 
quarters in which the bank computes its risk-based capital ratios using 
the Basel I rule and the advanced approaches rule, and required risk- 
based capital must be at least 85 percent of the Basel I requirement. 

[13] Banks must hold total capital equal to at least 8 percent of the 
total value of their risk-weighted assets and Tier 1 capital of at 
least 4 percent. Tier 1 capital is considered most stable and readily 
available for supporting a bank's operations. It covers core capital 
elements, such as common stockholder's equity and noncumulative 
perpetual preferred stock. All assets are assigned a risk weight 
according to the credit risk of the obligor or the nature of the 
exposure and the nature of any qualifying collateral or guarantee, 
where relevant. Off-balance sheet items, such as credit derivatives and 
loan commitments, are converted into credit equivalent amounts and also 
assigned risk weights. The risk weight categories are broadly intended 
to assign higher-risk weights to--and require banks to hold more 
capital for--higher-risk assets, and vice versa. See 12 C.F.R. Part 3 
(OCC); 12 C.F.R Part 208 and Part 225, App. A & B (Federal Reserve); 12 
C.F.R. Part 325 (FDIC); and 12 C.F.R. Part 567 (OTS). 

[14] Banks and thrifts holding the highest supervisory rating have a 
minimum leverage ratio of 3 percent; all other banks must meet a 
leverage ratio of at least 4 percent. See 12 C.F.R. §§ 3.6 (OCC), 208 & 
App. B (FRB), 325.3 (FDIC), and 567.8 (OTS). Bank holding companies 
that have adopted the MRA or hold the highest supervisory rating are 
subject to a 3 percent minimum leverage ratio; all other bank holding 
companies must meet a 4 percent minimum leverage ratio. 12 C.F.R. Part 
225, App. D. Thrift holding companies are not subject to specific risk- 
based or leverage ratios, but are instead required by OTS to hold 
adequate capital at the holding company level. 

[15] See GAO, Deposit Insurance: Assessment of Regulators' Use of 
Prompt Corrective Action and FDIC's New Deposit Insurance System, GAO-
07-242 (Washington, D.C.: Feb. 15, 2007), which responds to a 
legislative mandate that GAO review federal banking regulators' 
administration of the prompt corrective action program (P.L. 109-173, 
Federal Deposit Insurance Reform Conforming Amendments Act of 2005, 
Section 6(a), Feb. 15, 2006).

responsibilities of OTS and SEC with regard to these firms.

[18] Consolidated data for thrift holding companies that would be 
comparable to the information in table 2 is not readily available from 
OTS. By looking at those thrifts that make up a high percentage of the 
assets of the holding company, we see that thrifts and thus their 
holding companies hold a higher percentage of their assets in retail 
markets especially mortgage markets. They have only a small percentage 
of their assets in wholesale markets and these are concentrated in 
commercial real estate. Those thrift holding companies where the thrift 
is not a large part of the holding company are often in a wide range of 
businesses outside of banking including insurance, retail sales, and 
manufacturing. As a result only a few of these such as GE Capital 
Company and Ameriprise Financial Inc. would be competing with bank 
holding companies.

Banks in SME Credit Markets in the United States," Journal of Financial

[22] Holding capital involves balancing the needs of creditors and 
equity investors. More capital reassures creditors that banks will be 
able to repay loans, which reduces the cost of borrowing. But more 
capital also means that banks retain more shareholder equity, which 
reduces return on equity, an important benchmark for investors. 

[23] In previous work, officials at several banks told us that they 
weigh a number of factors when deciding how much capital to hold, 
including regulatory requirements, internal economic capital models, 
strategic needs, and market expectations, which are often exemplified 
by assessments from credit rating agencies such as Moody's and Standard 
and Poor's. Officials at one of these rating agencies agreed that banks 
manage capital to meet these demands. 

[24] In particular, there is very little "exogenous variation" 
(variation caused by regulation and not by banks themselves) in minimum 
capital requirements across banks, making it extremely difficult to 
estimate the impact of changes or differences in minimum capital 
requirements. 

[25] A decrease in required capital was met with a reduction in actual 
capital of only 20 percent of the size of the decrease in required 
capital. However, it is not clear that these quantitative estimates 
would apply to banks competing in the United States. Because small 
banks tend to hold a relatively large buffer of capital over minimum 
requirements, changes in those requirements may result in relatively 
little change in the amount of capital these banks hold. Isaac Alfon,

capital requirements affect capital at UK banks and building 
societies." Documentos de Trabajo No. 0515, Banco De España, 2005.

[29] See appendix III for a timeline of Basel II implementation in the 
United States. 

[30] Of the foreign countries we visited, only Canada has a leverage 
requirement that is similar in some ways to the one in the United 
States. The Swiss National Bank is also considering the introduction of 
a leverage requirement. Some Basel Committee member countries have 
other supplementary capital measures, akin to the well-capitalized 
designation for U.S. depository institutions, which are generally based 
on risk and assessed in Pillar 1 or Pillar 2. 

[31] The Basel Committee has issued general principles for information 
sharing between home and host countries. See Basel Committee, Home-host 
Information Sharing for Effective Basel II Implementation (Basel,

[32] Established in 1996 under the aegis of the Basel Committee, the 
International Organization of Securities Commissions, and the 
International Association of Insurance Supervisors, the Joint Forum on 
Financial Conglomerates (Joint Forum) deals with issues common to the 
banking, securities, and insurance sectors, including the regulation of 
financial conglomerates. 

[33] A number of factors could have caused QIS-4 to either 
underestimate or overestimate minimum required capital. In addition, 
the sensitivity of the advanced approaches to economic conditions and 
the good economic environment during QIS-4 were important factors in 
explaining lower estimates of required capital. There are some 
limitations associated with the data from QIS-4. At the time, the 
regulators emphasized that the QIS-4 was conducted on a "best efforts" 
basis with limited data and without the benefit of fully articulated 
final rules for U.S. implementation. 

[34] Note that neither study's conclusions are based on an analysis of 
a standardized approach. Paul S. Calem and James F. Follain, 
"Regulatory Capital Arbitrage and the Potential Competitive Impact of 
Basel II in the Market for Residential Mortgages," Journal of Real 
Estate Finance and Economics, vol. 35 (2007), and Diana Hancock, 
Andreas Lehnert, Wayne Passmore, and Shane M. Sherlund, An Analysis of 
the Potential Competitive Impacts of Basel II Capital Standards on U.S. 
Mortgage Rates and Mortgage Securitization, Federal Reserve Board 
(April 2005). 

[35] The proposed standardized rule incorporates many features that 
U.S. regulators proposed in Basel IA, which also was proposed to limit 
potential competitive advantages core banks may have had over non-core 
banks. For example, Basel IA included the increased risk-sensitivity in 
residential mortgages that is also in the proposed standardized 
approach. 

[36] Alternatively, banks could eliminate the leverage requirement and 
receive the lower, risk-based capital requirement by converting the 
asset to an off-balance sheet activity, such as by selling a guarantee 
on that asset in the event of default. To the extent risk-based capital 
requirements decrease for some assets under the advanced approaches, 
the incentive for core banks to do so may increase.

Framework (Basel, Switzerland: July 2008).

and Supervision (Basel, Switzerland: June 2008). Liquidity risk is the 
risk that a bank will be unable to meet its obligations when they come 
due, because of an inability to liquidate assets or obtain adequate 
funding. 

[39] See GAO-07-154. 

[40] Under the final rule, other issues that regulators will consider 
as part of the study are: the potential cyclical implications of the 
rule; comparison of regulatory capital requirements to market-based 
measures of capital adequacy, such as risk premiums on subordinated 
debt; examination of robustness of risk management processes related to 
capital adequacy; and analysis of interest rate and concentration 
risks.
