This report presents the outcomes of the Basel Committee on Banking Supervision's work regarding the revision of regulations on capital adequacy for internationally active banks. It outlines the agreed framework for measuring capital adequacy and the minimum standards to be achieved, which will be proposed by national supervisory authorities. The Committee encourages authorities to adopt this revised framework…
Title: Basel II - International Convergence of Capital Measurement and Capital Standards: A Revised Framework
Author: Basel Committee on Banking Supervision
Date: June 2004
Type: regulatory standard
Scope: revised framework for the measurement and capital standards of internationally active banks, including minimum capital requirements, supervisory review, and market discipline. The document covers credit risk, operational risk, market risk, as well as banking group consolidation and management of significant investments. Target population: internationally active banks, banking supervisory authorities. Sector: international banking sector. Period: framework applicable from end 2006, with transition until end 2008 for certain advanced approaches (p. 1-8, 13-18).
The document presents the revised Basel II framework, adopted by the Basel Committee, aiming to strengthen the soundness and stability of the international banking system while ensuring a level playing field among internationally active banks (p. 13-18). This framework rests on three pillars: minimum capital requirements (pillar 1), supervisory review process (pillar 2), and market discipline through transparency (pillar 3).
The importance of this framework lies in its ability to integrate more risk-sensitive methods, notably through the use of banks' internal assessments (IRB approach) for capital requirement calculations, while maintaining a regulatory minimum threshold of 8% risk-weighted capital (p. 14-15, 24-26).
Key findings are:
- The framework retains key elements of the 1988 Accord, notably the minimum 8% capital ratio on risk-weighted assets.
- It introduces a range of approaches for credit and operational risk, from standardized methods to advanced approaches based on internal ratings.
- It provides transitional mechanisms and prudential floors to ensure stability during the implementation of advanced approaches.
- Banking group consolidation is required to avoid double counting of capital, with precise rules on the treatment of banking, financial, insurance subsidiaries and significant investments (p. 19-23).
- The framework encourages enhanced cooperation among national supervisory authorities, especially between home and host countries.
Conclusions emphasize that Basel II is an evolving framework, designed to adapt to market developments and risk management practices. The Committee plans continuous monitoring and adjustments if necessary, notably via a calibration factor set at 1.06 according to impact studies (p. 14, 16, 24).
Recommendations are:
- Progressive adoption of the framework by national authorities, with implementation planned from end 2006 for standardized approaches and end 2007 for advanced approaches.
- Rigorous application of the three pillars, particularly strengthening pillar 2 (supervisory review) and pillar 3 (transparency) to complement minimum requirements.
- Close monitoring of interactions between accounting and regulatory standards.
- Continued dialogue with the banking industry to refine internal models and the definition of eligible capital.
- Development of international cooperation among supervisors to ensure consistent application (p. 13-18).
This document was developed by the Basel Committee to revise the 1988 framework on capital requirements for internationally active banks, to respond to changes in financial markets and risk management practices (p. 13). The fundamental objective is to strengthen the soundness and stability of the global banking system while ensuring fair competition among banks.
The framework aims to introduce increased risk sensitivity in capital requirement calculations, notably through the use of internal approaches (IRB) and the inclusion of operational risk, which had been little addressed until now (p. 14).
The challenges are to ensure that banks hold sufficient capital to cover their risks while avoiding competitive distortions due to divergent rules. The framework must also promote better risk management practices in the banking industry.
The scope covers internationally active banks and their consolidated groups, including banking, financial, insurance subsidiaries and significant investments. The framework applies on a consolidated basis, with precise rules for the treatment of non-consolidated entities (p. 19-23).
Announced limitations include the need to adapt implementation to national specificities, the complexity of advanced approaches requiring a transition period, and recognition that the framework sets minimums which national authorities may strengthen (p. 13-18).
1. Framework structure and three pillars:
- The framework rests on three pillars: minimum capital requirements (pillar 1), supervisory review (pillar 2), and market discipline through transparency (pillar 3) (p. 13-18).
2. Scope and consolidation:
- Application on a consolidated basis to international banking groups to avoid double counting of capital (p. 19).
- Inclusion of banking, financial and, under conditions, insurance subsidiaries, with specific rules for significant minority investments and commercial entities (p. 19-23).
- Capital deductions for significant investments exceeding certain thresholds (e.g., 15% of capital for individual investments in commercial entities) (p. 22).
3. Minimum capital requirements (Pillar 1):
- Minimum total capital ratio of 8% of risk-weighted assets (p. 24).
- Definition of regulatory capital maintained with adjustments for general provisions depending on the approach used (standardized or IRB) (p. 41-43).
- Calculation of risk-weighted assets including credit, market, and operational risk (p. 24).
- Application of scaling factors to calibrate overall capital level, estimated at 1.06 according to impact studies (p. 14, 24).
- Transitional provisions with capital floors based on the old framework for IRB and AMA approaches, decreasing between 2006 and 2008 (p. 45-49).
4. Approaches for credit risk:
- Standardized approach based on recognized external ratings, with precise weighting scales by counterparty type (sovereign, banks, corporates, etc.) (p. 27-32).
- Two options for bank risk: weighting linked to sovereign rating or to the bank’s own rating (p. 29-30).
- Precise criteria for inclusion of exposures in retail portfolios, with 75% weighting under conditions of diversification and exposure limits (p. 31-32).
5. Operational risk:
- Formal introduction of operational risk in capital requirement calculations.
- Three proposed methods: basic indicator approach, standardized approach, and advanced measurement approaches (AMA) (p. 137-149).
6. Trading book and market risk:
- Precise definition of the trading book.
- Prudent valuation methods (mark-to-market, mark-to-model) with independent controls.
- Specific treatment of counterparty risk and specific risk in the trading book (p. 150-156).
7. Supervisory review (Pillar 2):
- Importance of thorough examination by supervisors of risk and capital adequacy.
- Four key principles: governance, risk assessment, internal control, and supervisory response (p. 158-165).
- Consideration of specific risks such as interest rate risk in the banking book, concentration risk, and operational risk (p. 165-168).
8. Market discipline (Pillar 3):
- Requirements for transparency and disclosure of qualitative and quantitative information on capital, risks, and management methods.
- Objective to enhance market discipline by providing investors and stakeholders with reliable information (p. 175-190).
9. Eligible capital and innovative instruments:
- Maintenance of existing definitions with adjustments for provisions and expected losses.
- Limitation of innovative instruments to 15% of Tier 1 (p. 37, annex 1).
10. International cooperation:
- Key role of home country supervisors to coordinate with host countries.
- Establishment of working groups to ensure consistency and reduce implementation burdens (p. 15).
11. Scalability and monitoring:
- The framework is designed to evolve with market and risk management practices.
- The Committee plans continuous monitoring and adjustments, notably on recognition of double default effects and capital definition (p. 16-17).
Established facts:
- The Basel II framework imposes a minimum capital ratio of 8% of risk-weighted assets, with a precise definition of regulatory capital and risk-weighted assets (p. 24).
- Application is consolidated at the level of international banking groups, including banking, financial and, under conditions, insurance subsidiaries (p. 19-23).
- Two main approaches for credit risk: standardized (with external ratings) and internal (IRB) (p. 27-32, 48-112).
- Formal introduction of operational risk with several calculation methods (p. 137-149).
- Existence of transitional mechanisms and capital floors to ensure stability during implementation (p. 45-49).
Assumptions:
- The overall capital adjustment factor is estimated at 1.06, based on quantitative impact studies (p. 14, 24).
- Internal IRB approaches assume banks have robust risk assessment systems, validated by supervisors (p. 14, 48-112).
Interpretations:
- The framework aims to encourage improvement of risk management practices by banks, integrating internal assessments more into capital calculation (p. 14).
- Full consolidation aims to avoid double counting of capital and to faithfully reflect group risks (p. 19-23).
- Market discipline through transparency is considered an essential complement to minimum requirements and supervisory review (p. 175-190).
Uncertainties:
- Implementation of advanced approaches will depend on banks’ and supervisors’ capacity to meet minimum requirements and validate internal models (p. 14, 48-112).
- The impact of interactions between accounting and regulatory standards remains to be monitored (p. 12).
- Treatment of double default and final definition of eligible capital are still under study (p. 16-17).
The Basel Committee concludes that the revised Basel II framework represents a major advance for the prudential regulation of international banks, strengthening risk sensitivity and integrating modern risk management practices (p. 13-18).
It recommends:
- Progressive adoption of the framework by national authorities, with implementation planned from end 2006 for standardized approaches and end 2007 for advanced approaches, accompanied by transition periods and parallel calculations (p. 13, 45-49).
- Rigorous application of the three pillars, particularly strengthening supervisory review processes (pillar 2) and transparency requirements (pillar 3) to ensure effective oversight and market discipline (p. 11, 158-190).
- Establishment of enhanced cooperation among national supervisors, notably between home and host countries, to guarantee consistency and reduce implementation burdens (p. 15).
- Continued dialogue with the banking industry to refine internal models, recognition of double default effects, and definition of eligible capital (p. 16-17).
- Continuous monitoring of the framework, with the possibility to adjust calibrations and apply adjustment factors to maintain an adequate overall capital level (p. 14, 24).
The Committee emphasizes that the framework is evolving and that its success will depend on the quality of implementation by banks and supervisory authorities.
