The Basle Committee on Banking Supervision (BCBS) had issued comprehensive guidelines to provide an explicit capital cushion for the price risks to which banks are exposed, particularly those arising from their trading activities. The banks have been given flexibility to use in-house models based on VaR for measuring market risk as an alternative to a standardised measurement framework suggested by Basle Committee. The internal models should, however, comply with quantitative and qualitative criteria prescribed by Basle Committee. Reserve Bank of India has accepted the general framework suggested by the Basle Committee. RBI has also initiated various steps in moving towards prescribing capital for market risk. As an initial step, a risk weight of 2.5% has been prescribed for investments in Government and other approved securities, besides a risk weight each of 100% on the open position limits in forex and gold. RBI has also prescribed detailed operating guidelines for Asset-Liability Management System in banks. As the ability of banks to identify and measure market risk improves, it would be necessary to assign explicit capital charge for market risk. While the small banks operating predominantly in India could adopt the standardised methodology, large banks and those banks operating in international markets should develop expertise in evolving internal models for measurement of market risk. The Basle Committee on Banking Supervision proposes to develop capital charge for interest rate risk in the banking book as well for banks where the interest rate risks are significantly above average ('outliers'). The Committee is now exploring various methodologies for identifying 'outliers' and how best to apply and calibrate a capital charge for interest rate risk for banks. Once the Committee finalises the modalities, it may be necessary, at least for banks operating in the international markets to comply with the explicit capital charge requirements for interest rate risk in the banking book. As the valuation norms on banks' investment portfolio have already been put in place and aligned with the international best practices, it is appropriate to adopt the Basel norms on capital for market risk. In view of this, banks should study the Basel framework on capital for market risk as envisaged in Amendment to the Capital Accord to incorporate market risks published in January 1996 by BCBS and prepare themselves to follow the international practices in this regard at a suitable date to be announced by RBI. The Basel Committee on Banking Supervision has released a Second Consultative Document, which contains refined proposals for the three pillars of the New Accord - Minimum Capital Requirements, Supervisory Review and Market Discipline. It may be recalled that the Basel Committee had released in June 1999 the first Consultative Paper on a New Capital Adequacy Framework for comments. However, the proposal to provide explicit capital charge for market risk in the banking book which was included in the Pillar I of the June 1999 Document has been shifted to Pillar II in the second Consultative Paper issued in January 2001. The Committee has also provided a technical paper on evaluation of interest rate risk management techniques. The Document has defined the criteria for identifying outlier banks. According to the proposal, a bank may be defined as an outlier whose economic value declined by more than 20% of the sum of Tier 1 and Tier 2 capital as a result of a standardised interest rate shock (200 bps.) The second Consultative Paper on the New Capital Adequacy framework issued in January, 2001 has laid down 13 principles intended to be of general application for the management of interest rate risk, independent of whether the positions are part of the trading book or reflect banks' non-trading activities. They refer to an interest rate risk management process, which includes the development of a business strategy, the assumption of assets and liabilities in banking and trading activities, as well as a system of internal controls. In particular, they address the need for effective interest rate risk measurement, monitoring and control functions within the interest rate risk management process. The principles are intended to be of general application, based as they are on practices currently used by many international banks, even though their specific application will depend to some extent on the complexity and range of activities undertaken by individual banks. Under the New Basel Capital Accord, they form minimum standards expected of internationally active banks. The principles are given in Annexure II. Annexure-I Structure for Managing Liquidity Principle 1: Each bank should have an agreed strategy for the day-to-day management of liquidity. This strategy should be communicated throughout the organisation. Principle 2: A bank's board of directors should approve the strategy and significant policies related to the management of liquidity. The board should also ensure that senior management takes the steps necessary to monitor and control liquidity risk. The board should be informed regularly of the liquidity situation of the bank and immediately if there are any material changes in the bank's current or prospective liquidity position Principle 3: Each bank should have a management structure in place to execute effectively the liquidity strategy. This structure should include the ongoing involvement of members of senior management. Senior management must ensure that liquidity is effectively managed, and that appropriate policies and procedures are established to control and limit liquidity risk. Banks should set and regularly review limits on the size of their liquidity positions over particular time horizons. Principle 4: A bank must have adequate information systems for measuring, monitoring, controlling and reporting liquidity risk. Reports should be provided on a timely basis to the bank's board of directors, senior management and other appropriate personnel Principle 5: Each bank should establish a process for the ongoing measurement and monitoring of net funding requirements. Principle 6: A bank should analyse liquidity utilising a variety of "what if" scenarios. Principle 7: A bank should review frequently the assumptions utilised in managing liquidity to determine that they continue to be valid. Principle 8: Each bank should periodically review its efforts to establish and maintain relationships with liability holders, to maintain the diversification of liabilities, and aim to ensure its capacity to sell assets. Principle 9: A bank should have contingency plans in place that address the strategy for handling liquidity crises and include procedures for making up cash flow shortfalls in emergency situations Principle 10: Each bank should have a measurement, monitoring and control system for its liquidity positions in the major currencies in which it is active. In addition to assessing its aggregate foreign currency liquidity needs and the acceptable mismatch in combination with its domestic currency commitments, a bank should also undertake separate analysis of its strategy for each currency individually. Principle 11: Subject to the analysis undertaken according to Principle 10, a bank should, where appropriate, set and regularly review limits on the size of its cash flow mismatches over particular time horizons for foreign currencies in aggregate and for each significant individual currency in which the bank operates. Principle 12: Each bank must have an adequate system of internal controls over its liquidity risk management process. A fundamental component of the internal control system involves regular independent reviews and evaluations of the effectiveness of the system and, where necessary, ensuring that appropriate revisions or enhancements to internal controls are made. The results of such reviews should be available to supervisory authorities. Principle 13: Each bank should have in place a mechanism for ensuring that there is an adequate level of disclosure of information about the bank in order to manage public perception of the organisation and its soundness.
Annexure II Board and senior management oversight of interest rate risk Principle 1: In order to carry out its responsibilities, the board of directors in a bank should approve strategies and policies with respect to interest rate risk management and ensure that senior management takes the steps necessary to monitor and control these risks. The board of directors should be informed regularly of the interest rate risk exposure of the bank in order to assess the monitoring and controlling of such risk. Principle 2: Senior management must ensure that the structure of the bank's business and the level of interest rate risk it assumes are effectively managed, that appropriate policies and procedures are established to control and limit these risks, and that resources are available for evaluating and controlling interest rate risk. Principle 3: Banks should clearly define the individuals and/or committees responsible for managing interest rate risk and should ensure that there is adequate separation of duties in key elements of the risk management process to avoid potential conflicts of interest. Banks should have risk measurement, monitoring and control functions with clearly defined duties that are sufficiently independent from position-taking functions of the bank and which report risk exposures directly to senior management and the board of directors. Larger or more complex banks should have a designated independent unit responsible for the design and administration of the bank's interest rate risk measurement, monitoring and control functions. Principle 4: It is essential that banks' interest rate risk policies and procedures are clearly defined and consistent with the nature and complexity of their activities. These policies should be applied on a consolidated basis and, as appropriate, at the level of individual affiliates, especially when recognising legal distinctions and possible obstacles to cash movements among affiliates. Principle 5: It is important that banks identify the risks inherent in new products and activities and ensure these are subject to adequate procedures and controls before being introduced or undertaken. Major hedging or risk management initiatives should be approved in advance by the board or its appropriate delegated committee. Principle 6: It is essential that banks have interest rate risk measurement systems that capture all material sources of interest rate risk and that assess the effect of interest rate changes in ways that are consistent with the scope of their activities. The assumptions underlying the system should be clearly understood by risk managers and bank management. Principle 7:: Banks must establish and enforce operating limits and other practices that maintain exposures within levels consistent with their internal policies. Principle 8: Banks should measure their vulnerability to loss under stressful market conditions - including the breakdown of key assumptions - and consider those results when establishing and reviewing their policies and limits for interest rate risk. Principle 9: Banks must have adequate information systems for measuring, monitoring, controlling and reporting interest rate exposures. Reports must be provided on a timely basis to the bank's board of directors, senior management and, where appropriate, individual business line managers. Internal controls Principle 10: Banks must have an adequate system of internal controls over their interest rate risk management process. A fundamental component of the internal control system involves regular independent reviews and evaluations of the effectiveness of the system and, where necessary, ensuring that appropriate revisions or enhancements to internal controls are made. The results of such reviews should be available to the relevant supervisory authorities. Principle 11: Supervisory authorities should obtain from banks sufficient and timely information with which to evaluate their level of interest rate risk. This information should take appropriate account of the range of maturities and currencies in each bank's portfolio, including off-balance sheet items, as well as other relevant factors, such as the distinction between trading and non-trading activities Principle 12: Banks must hold capital commensurate with the level of interest rate risk they undertake. Principle 13: Banks should release to the public information on the level of interest rate risk and their policies for its management. **Principles for the Management and Supervision of Interest Rate Risk, Supporting Document to the New Basel Capital Accord, BCBS, January, 2001 Connected Reading |
