LECTURE – 28 KEY PRINCIPLES OF SUPERVISORY REVIEW Supervisors should consider a range of options if they become concerned that a bank is not meeting the requirements embodied in the supervisory principles explained in last lecture. These actions may include intensifying the monitoring of the bank, restricting the payment of dividends, requiring the bank to prepare and implement a satisfactory capital adequacy restoration plan, and requiring the bank to raise additional capital immediately. Supervisors should have the discretion to use the tools best suited to the circumstances of the bank and its operating environment. Specific issues to be addressed under the supervisory review process The Committee has identified a number of important issues that banks and supervisors should particularly focus on when carrying out the supervisory review process. These issues include some key risks which are not directly addressed under Pillar 1 and important assessments that supervisors should make to ensure the proper functioning of certain aspects of Pillar 1. Interest rate risk in the banking book The Committee remains convinced that interest rate risk in the banking book is a potentially significant risk which merits support from capital. However, comments received from the industry and additional work conducted by the Committee have made it clear that there is considerable heterogeneity across internationally active banks in terms of the nature of the underlying risk and the processes for monitoring and managing it. In light of this, the Committee has concluded that it is at this time most appropriate to treat interest rate risk in the banking book under Pillar 2 of the Framework. Nevertheless, supervisors who consider that there is sufficient homogeneity within their banking populations regarding the nature and methods for monitoring and measuring this risk could establish a mandatory minimum capital requirement. The revised guidance on interest rate risk recognizes banks’ internal systems as the principal tool for the measurement of interest rate risk in the banking book and the supervisory response. To facilitate supervisors’ monitoring of interest rate risk exposures across institutions, banks would have to provide the results of their internal measurement systems, expressed in terms of economic value relative to capital, using a standardized interest rate shock. If supervisors determine that banks are not holding capital commensurate with the level of interest rate risk, they must require the bank to reduce its risk, to hold a specific additional amount of capital or some combination of the two. Supervisors should be particularly attentive to the sufficiency of capital of ‘outlier banks’ where economic value declines by more than 20% of the sum of Tier 1 and Tier 2 capital as a result of a standardized interest rate shock (200 basis points) or its equivalent, as described in the supporting document Principles for the Management and Supervision of Interest Rate Risk. Credit concentration risk A risk concentration is any single exposure or group of exposures with the potential to produce losses large enough (relative to a bank’s capital, total assets, or overall risk level) to threaten a bank’s health or ability to maintain its core operations. Risk concentrations are arguably the single most important cause of major problems in banks. Risk concentrations can arise in a bank’s assets, liabilities, or off-balance sheet items, through the execution or processing of transactions (either product or service), or through a combination of exposures across these broad categories. Because lending is the primary activity of most banks, credit risk concentrations are often the most material risk concentrations within a bank. Credit risk concentrations, by their nature, are based on common or correlated risk factors, which, in times of stress, have an adverse effect on the creditworthiness of each of the individual counterparties making up the concentration. Concentration risk arises in both direct exposures to obligors and may also occur through exposures to protection providers. Such concentrations are not addressed in the Pillar 1 capital charge for credit risk. docsity.com Banks should have in place effective internal policies, systems and controls to identify, measure, monitor, and control their credit risk concentrations. Banks should explicitly consider the extent of their credit risk concentrations in their assessment of capital adequacy under Pillar 2. These policies should cover the different forms of credit risk concentrations to which a bank may be exposed. Such concentrations include: 1. Significant exposures to an individual counterparty or group of related counterparties. In many jurisdictions, supervisors define a limit for exposures of this nature, commonly referred to as a large exposure limit. Banks might also establish an aggregate limit for the management and control of all of its large exposures as a group; 2. Credit exposures to counterparties in the same economic sector or geographic region; 3. Credit exposures to counterparties whose financial performance is dependent on the same activity or commodity; and 4. Indirect credit exposures arising from a bank’s Credit Risk Mitigation activities (e.g. exposure to a single collateral type or to credit protection provided by a single counterparty). A bank’s framework for managing credit risk concentrations should be clearly documented and should include a definition of the credit risk concentrations relevant to the bank and how these concentrations and their corresponding limits are calculated. Limits should be defined in relation to a bank’s capital, total assets or, where adequate measures exist, its overall risk level. A bank’s management should conduct periodic stress tests of its major credit risk concentrations and review the results of those tests to identify and respond to potential changes in market conditions that could adversely impact the bank’s performance. Counterparty credit risk As counterparty credit risk (CCR) represents a form of credit risk, this would include meeting this Framework’s standards regarding their approaches to stress testing, “residual risks” associated with credit risk mitigation techniques, and credit concentrations. The bank must have counterparty credit risk management policies, processes and systems that are conceptually sound and implemented with integrity relative to the sophistication and complexity of a firm’s holdings of exposures that give rise to CCR. A sound counterparty credit risk management framework shall include the identification, measurement, management, approval and internal reporting of CCR. The bank’s risk management policies must take account of the market, liquidity, legal and operational risks that can be associated with CCR and, to the extent practicable, interrelationships among those risks. The bank must not undertake business with a counterparty without assessing its creditworthiness and must take due account of both settlement and pre-settlement credit risk. These risks must be managed as comprehensively as practicable at the counterparty level (aggregating counterparty exposures with other credit exposures) and at the firm-wide level. The board of directors and senior management must be actively involved in the CCR control process and must regard this as an essential aspect of the business to which significant resources need to be devoted. Where the bank is using an internal model for CCR, senior management must be aware of the limitations and assumptions of the model used and the impact these can have on the reliability of the output. They should also consider the uncertainties of the market environment (e.g. timing of realization of collateral) and operational issues (e.g. pricing feed irregularities) and be aware of how these are reflected in the model. In this regard, the daily reports prepared on a firm’s exposures to CCR must be reviewed by a level of management with sufficient seniority and authority to enforce both reductions of positions taken by individual credit managers or traders and reductions in the firm’s overall CCR exposure. The bank’s CCR management system must be used in conjunction with internal credit and trading limits. In this regard, credit and trading limits must be related to the firm’s risk measurement model in a manner that is consistent over time and that is well understood by credit managers, traders and senior management. The measurement of CCR must include monitoring daily and intra-day usage of credit lines. The bank must measure current exposure gross and net of collateral held where such measures are appropriate and meaningful (e.g. OTC docsity.com
