This statement sets out the
principles on which a system of bank capital regulation should be
based, shows how the proposed New Basel Capital Accord fails to meet
these standards, and provides recommendations which would significantly
improve capital regulations. These recommendations are based on our
strong belief that regulators are not generally in a better position to
assess risk than financial market participants. I. Principles All proposals to reform or improve
capital regulation should, in our view, adhere to the principles below.
While we recognize that making these principles operational and
implementing them will have to take account of specific conditions in
individual countries, they should nevertheless guide the development
and implementation of capital regulation in all countries. 1. Banks should maintain a level of capital that is sufficient to: 2. Capital should be measured so as to maximize the use of market information. 3. Capital levels and risk exposures should be disclosed publicly and frequently. 4.
Bank supervision should be administered by competent regulators who are
independent of political and bank industry pressures and are publicly
accountable. 5. Rules and supervision should be designed to enhance market discipline. 6. Rules should be designed to identify and disclose connected lending and provide appropriate safeguards. 7. Rules should include an effective mechanism for enforcement of capital regulations. II. Inadequacies of the Basel proposal with respect to the principles of capital regulation 1. The Basel proposal will not cause banks to maintain a sufficient level of capital relative to their risk exposures. The use of a bank's internal ratings provides many opportunities to game the rules.
The proposed accord allows banks to use internal ratings under certain
conditions, subject to evaluation and acceptance by the bank’s
supervisory authority. This evaluation is complicated by the fact that
banks’ practices in credit-risk assessment vary substantially, from the
highly intuitive placement of credits into risk categories to the use
of fairly sophisticated risk-assessment models. The ability of
supervisors to prevent gaming is likely to be limited despite the more
intensive supervision recommended in the proposal. This is important
because banks have an incentive to minimize required regulatory capital
for a given level of economic risk. External ratings cannot be counted on to measure adequately the risks associated with bank loans. With
respect to external ratings, there are a number of difficulties. Rating
agencies have little experience in risk-rating bank borrowers; rating
each and every bank borrower would be very costly; and the agencies’
track record suggests that they have been better at risk confirmation
than risk diagnosis. Furthermore, were ratings to be used for the
purpose of determining required capital, it is likely that rating firms
would be established to provide biased ratings. A separate
concern is that firms and banks in emerging market economies may be
adversely affected by any sudden downgrade of their home country's
sovereign rating. 2. The proposal does not require that capital be measured on a market value basis. 3.
Although the recommendations and requirements for additional
disclosures are desirable and will provide more information, the
proposal does not go far enough to enhance the role of market
discipline in determining capital adequacy. The Basel Committee relies
on information disclosure to create market discipline. However,
effective market discipline requires not only that information be
available to the market, but also that market participants have the
incentive to act on it. As long as depositors and other creditors of
banks are explicitly or implicitly protected against loss, they will be
less inclined to demand relevant disclosure concerning risks or losses
and to act on the information that is disclosed. 4.
The number and complexity of the proposed rules will make it harder to
hold regulators and supervisors accountable for their judgements about
bank risk, and may result in increased regulatory forbearance. 5.
Regulators need to address more urgently significant conflict of
interest problems that have often caused bank failures in many
countries, particularly the problem of "connected lending" — loans to
insiders, major shareholders, and their affiliates. 6.
Although the Basel Committee apparently did not consider enforcement to
be within their mandate, it should be clear that no capital regulation
regime can be effective without a strong enforcement mechanism. III. Recommendations The following recommendations, which
could be adapted to the circumstances of individual countries, reflect
our concerns on two key issues. The first is the need for an effective
enforcement regime. The second is the fact that regulatory reliance on
internal ratings lacks transparency, strengthening the need for
supplementary measures aimed at increasing market discipline. Capital requirements need effective
enforcement. In the United States, for example, a system known as
prompt corrective action attempts to mimic the sanctions the market
would impose in the absence of a government-sponsored safety net. An
effective enforcement mechanism based on this model should include the
following features:
(a) reduce the likelihood of bank insolvencies to a level consistent with a stable banking system;
(b) immunize taxpayers from losses incurred by government-guaranteed bank claimants in the event of bank insolvencies; and
(c)
align the incentives of bank owners and managers with those of
uninsured bank claimants with respect to the risk assumed by banks.
-
multiple capital zones with progressively stricter regulatory sanctions,
-
a specified equity closure rule when the equity is still above zero,
-
resolution of insolvencies at least cost to tax payers.
The appropriate amount of capital
should resemble what banks would hold in the absence of a
government-sponsored safety net. Thus, in addition to the Basel
risk-weighted ratios, the relevant capital standard would include a
leverage ratio based on total assets (both on- and off-balance sheet
assets). In order to strengthen market
discipline, we recommend that banks in industrialized countries issue a
minimum amount of credibly uninsured subordinated debt. Holders of such
debt are sensitive to and uniquely positioned to monitor default risk.
Therefore, the Basel capital rules should be supplemented with signals
from these uninsured creditors. To encourage this, we recommend that
the distinction between Tier I and Tier II capital be removed. Although banks face a degree of
market discipline from the stock market in most industrialized
countries, the information provided by stock prices becomes
progressively less reliable as banks approach insolvency. This subordinated debt proposal can
be implemented experimentally in phases so as to minimize costs and
permit review of its effectiveness. Initially, the requirement could
be limited to large institutions whose debt is actively traded. In
addition, at the outset, the market signals from subordinated debt need
not mandate any required supervisory action; however, the yields at
which this debt trades will provide helpful information to both the
market and the supervisors. In the case of emerging markets,
effective use of subordinated debt as capital and as a signal of bank
strength may be limited by the absence of a liquid and developed
capital market. However, this should not prevent emerging market
countries from identifying and developing signals of bank strength--by
for example encouraging banks to offer credibly uninsured certificates
of deposit.
