The Application of Basel II to Trading Activities and the Treatment of Double Default Effects

Note: This document has been incorporated in the comprehensive version of International Convergence of Capital Measurement and Capital Standards: A Revised Framework, including the June 2004 Basel II Framework, the 1996 Amendment to the Capital Accord to Incorporate Market Risks, and the 2005 paper on The Application of Basel II to Trading Activities and the Treatment of Double Default Effects.

The efforts of the Basel Committee on Banking Supervision (BCBS) to revise the standards governing the capital adequacy of internationally active banks achieved a critical milestone in the publication of an agreed text in June 2004. The International Convergence of Capital Measurement and Capital Standards: a Revised Framework describes a more comprehensive measure and minimum standard for capital adequacy that national supervisory authorities represented on the BCBS are now working to implement through domestic rule-making and adoption procedures.

The "Basel II" framework, or Revised Framework, as the new standard is frequently called, seeks to improve on the existing rules by aligning regulatory capital requirements more closely to the underlying risks that banks face. In addition, the Revised Framework is intended to promote a more forward-looking approach to capital supervision, one that 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. As a result, the Revised Framework is intended to be more flexible and better able to evolve with advances in markets and risk management practices.

In releasing the Revised Framework last summer, the BCBS re-iterated its intention to maintain its active dialogue with the industry to ensure that the new framework keeps pace with, and can be applied to, ongoing developments in the financial services sector. Two areas that the BCBS identified where immediate work should be done concerned (1) finding a prudentially sound treatment under the Revised Framework for exposures to "double default," where the risk of both a borrower and a guarantor defaulting on the same obligation may be substantially lower than the risk of only one of the parties defaulting; and (2) applying the Revised Framework to certain exposures arising from trading activities.

Given the interest of both banks and securities firms in the potential solutions to these particular issues, the BCBS has worked jointly with the International Organization of Securities Commissions (IOSCO) to consult with industry representatives and other supervisors on these matters. This paper describes a proposal to address five specific issues related to double default and trading activities prior to the implementation of the Revised Framework. These issues consist of the following:

• the treatment of counterparty credit risk for over-the-counter derivatives, repo-style and securities financing transactions; and the treatment of cross-product netting arrangements;
• the treatment of double-default effects for covered transactions, in relation with trading book, but also banking book, exposures;
• the short-term maturity adjustment, in the internal ratings-based approach;
• improvements to the current trading book regime, especially with respect to the treatment of specific risk; and
• the design of a specific capital treatment for unsettled and failed transactions.

While this work was undertaken jointly by working groups from the BCBS and IOSCO, the resulting proposal represents an effort by the BCBS to find prudential treatments for certain exposures held by banks under the new capital standards outlined in the Revised Framework. Consequently, this text frequently refers to rules for "banks," banking groups, and other firms subject to prudential banking regulations. The BCBS recognises that, in some cases, national authorities may decide to apply these rules not just to banks and banking groups, but also to investment firms or to combined groups of banks and investment firms. In such cases, national authorities may additionally wish to apply the treatments specified in this proposal to investment firms, to groups of investment firms, and to combined groups of banks and investment firms that are subject to prudential banking or securities regulation.

The intent is to incorporate the proposals in the Revised Framework prior to its implementation in BCBS member jurisdictions. Due to the time constraints associated with national rulemaking processes and the adaptation of firms' information systems, the BCBS intends to release final rules in the summer 2005. Comments from the public on all aspects of the proposals are welcome by 27 May 2005 and should be addressed to both organisations at the following addresses:
