2. Basel II Accord-An Overview
The Basel Committee on Banking Supervision (BCBS) released the revised capital accord, also called, Basel II, on June 26, 2004. The document is called “International Convergence of Capital Measurement and Capital Standards: A Revised Framework”.
The Basel Committee on Banking Supervision (BCBS) released the revised capital accord, also called, Basel II, on June 26, 2004. The document is called “International Convergence of Capital Measurement and Capital Standards: A Revised Framework”.
The significant
features of Basel II are:
·
Significantly more
risk sensitive capital requirements and takes into account operational risk of
banks apart from credit and market risks. It also provides for risk treatment
based on securitization.
·
Great use of
assessment of risk provided by banks’ internal systems as inputs to capital
calculations.
·
Provides a range of
options for determining the capital requirements for credit risk and
operational risk to allow banks and national regulators to select the
approaches that are most suitable for them.
·
Capital requirement
under the new accord is the minimum. It has a provision for supplementary
capital that can be adopted by national regulators.
·
The Accord promotes
strong risk management practices by providing capital incentives for banks
having better risk management practices.
One most note that the
capital requirements under basel II do not include liquidity risk, interest
rate risk of banking book, strategic risk, and business risk. These risks would
fall under “Supervisory Review Process”. If supervisors feel that the capital
held by a bank is not sufficient, they could require the bank to reduce its
risk or increase its capital or both. With respect to interest rate risk on
banking book, the Accord puts in place a criteria for “Outliers”. Where a bank
under 200 basis points interest rate shock faces reduction in capital by 20% or
more, such banks would be outliers.
The Basel Accord is
based on three pillars:
1. Minimum Capital Requirements
2. Supervisory Review Process
3. Market Discipline
Pillar
I – Minimum Capital Requirements
Pillar I provides
details of how banks must calculate their minimum capital requirements. It
suggests various approaches for calculating capital for credit, market, and
operational risk.
Capital for Credit
Risk
·
Standardized Approach
·
Internal Ratings Based
(IRB) Foundation Approach
·
Internal Ratings Based
(IRB) Advanced Approach
Capital for Market
Risk
·
Standardized Approach
(Maturity Method)
·
Standardized Approach
(Duration Method)
·
Internal Models Method
Capital for
Operational Risk
·
Basic Indicator
Approach
·
Standardized Approach
·
Advanced Measurement
Approach
Pillar
2 – Supervisory Review Process
The Pillar II concerns
the supervisory approach to bank capital management. The objective here is to
ensure that banks follow rigorous procedures, measure their risk exposures
correctly, and have enough capital to cover their risks.
·
Evaluate risk
assessment
·
Ensure soundness and
integrity of bank’ internal process to assess the adequacy of capital
·
Ensure maintenance of
minimum capital – with PCA for shortfall
·
Prescribe differential
capital, where necessary, i.e., where the internal processes are slack.
Pillar
3 – Market Discipline
Pillar III introduces
requirements for banks to disclose their risk information to the financial
markets, in the hope that investors will be better able to exert discipline on
bank behavior.
·
Enhance Disclosure
·
Core disclosures and
supplementary disclosures
