Capital
adequacy is the key measure of the soundness and stability of banks. Basel II,
introduced in June 2004 by the Basel Committee on Banking Supervision based in
the Bank for International Settlements, Basel, Switzerland, is the current
international standard framework for assessing capital adequacy of banks. This
new framework replaces Basel I as the international capital adequacy norm for
banks.
The key features of
Basel II
The
Basel II capital framework comprises three mutually reinforcing pillars, i.e.,
(1)
Minimum capital requirements,
(2)
Supervisory review process and
(3)
Market discipline.
Pillar 1-The calculation of the minimum capital
requirements: The Pillar I aim to align the minimum capital requirement on
account of credit risk, market risk and operational risk, more closely with the
bank’s actual degree of risk. The options for calculating the capital charge
for credit risk are the standardized approach and internal ratings based
approaches (IRB).
The
standardized approach is based on external credit ratings while the IRB
approach, heavily relies on banks’ internal assessment of the components that
define the risk of a credit exposure. The IRB approach, in turn, comprises two
different methodologies: the foundation and advanced IRB approaches, depending
on the sophistication of risk management systems of the banks.
The
three options for calculating operational risk, which is a new feature in Basel
II, are the basic indicator approach, the standardized approach, and the
advanced measurement approach. A similar structure applies for measurement of
market risk.
Pillar 2-The
supervisory review process, aims to give supervisors more responsibility to
verify whether banks have taken account of their entire risk profile and
maintain sufficient capital to cover their risks and allows to capture the
risks not specifically covered under Pillar I. The additional risks that should
be considered by the regulators under Pillar 2 are credit concentration risk, treatment
of interest rate risk in the banking book, liquidity risk and strategic and
reputation risks. Accordingly, the regulators have the option of prescribe
additional capital to mitigate such additional risks.
Pillar 3-Market
Discipline requires banks to publicly disclose key information regarding their
risk exposure, risk appetite and performance with a view to promote market
discipline. It is expected that enhanced disclosure and transparency, will
allow market participants to better assess the safety and soundness of the
respective banks and thus exert stronger market discipline.
Overall Benefits of
Basel II
Basel
II is a comprehensive framework that provides banking institutions stronger
incentives to improve risk measurement and management and regulators to take
measures to improve safety and soundness of banks by more closely linking
regulatory capital requirements with banking risk.
The
Basel II Framework promotes a more forward-looking approach to capital
supervision, and encourages banks to identify the risks they may face, today
and in the future, and to develop or improve their ability to manage those
risks. The advanced approaches of Basel II also require banks to stress test
their portfolios based on a number of likely future scenarios. These features
shield banks from facing unanticipated problems and facilitate their smooth
functioning.
Further,
Basel II introduces the concept of market discipline whereby market
participants (such as depositors and shareholders of banks) also receive the
opportunity to exert discipline over banks and thus, contribute to improving
the financial strength of banks. Enhancing transparency and accountability
through publication of prudential ratios and other information regarding banks
enables the public to make better decisions regarding the management and
performance of the bank. As such, the market is in a position to reward a bank
displaying greater financial strength by giving it more business and penalising
those of poor quality by avoiding the conduct of business with such banks.
Implementation of Basel
II in Sri Lanka
Regulators
in most jurisdictions around the world have implemented the Basel II framework
and the Central Bank of Sri Lanka also joined the global trend by implementing
the Basel II, in January 2008. Accordingly, banks are required to apply the Standardized
Approach for credit risk, the Standardized Measurement Method for market risk
and the Basic Indicator Approach for operational risk, in computing the capital
requirements.
The
Central Bank has decided to move to more advanced approaches (IRB approaches)
beginning 2013. Once the Central Bank is satisfied that the banks have the
appropriate models and risk management systems capacities, the permission will
be granted for them to precede with the IRB advanced approaches.
