BIS Review 15/2003  5  Next Steps in finalizing the New Accord Most of my remarks today have been centered on implementation of the new framework. I’d like to conclude by spending a few moments discussing where we are in the process to finalize the New Accord. As I mentioned, the Committee has just finished gathering data from the industry through its third impact study. The aim of the study was to collect and to analyze information from banks worldwide regarding the capital impact of the new proposals on their existing portfolios. The results are under review and will help us to determine whether any adjustments will be needed prior to release of the final consultative package. That final consultative paper will be issued by early May. Our goal continues to be to have a final Accord agreed to by the fourth quarter of this year. In closing, I want to emphasize that effective supervision of modern banking organizations will necessarily entail a closer and more cooperative partnership between industry participants and official supervisors. The industry’s participation in the formulation of a more risk-sensitive capital adequacy framework is a good example of this kind of constructive interaction. Indeed, the three pillars of the proposed framework reflect the understanding that regulatory requirements alone are no longer sufficient to address the growing complexity of banks’ activities and the associated risks. Consistent with this notion is the need for effective corporate governance, which plays an increasingly important role in a rapidly evolving banking environment.
Rating system design  The first area concerns the design of a risk rating system, which is, of course, central to ensuring the effectiveness of the IRB approach. The Basel Committee believes that banks’ internal rating systems should accurately and consistently differentiate between degrees of risk. The minimum IRB standards in this area build on the strongest risk management practices observed in the industry. To illustrate the point, many organizations either already have, or are in the process of developing a ratings system that captures both the risk of borrower default, as well as transaction-specific factors that shed light on the amount of loss that would arise if default occurs. In other words, these banks’ systems are now oriented to capturing the several essential components in estimating credit risk under the IRB approach. Credit risk rating systems are clearly improving in various dimensions, including how finely they seek to distinguish differing degrees of borrower risk. To do so, banks typically look to expand the number of ratings categories into which they slot their exposures. However, just establishing more rating categories is not enough. The challenge is for banks to define clearly and objectively the criteria for these ratings categories in order to provide more meaningful assessments of both individual credit exposures and, ultimately, their overall risk profile. The clarity and transparency of the ratings criteria will be critical to ensuring that ratings are assigned in a disciplined and reliable manner. b.
