Quantitative Impact Study 4 (QIS-4)

The U.S. banking agencies are conducting the Quantitative Impact Study 4 (QIS-4) to better understand the likely effect of proposed international capital standards on the minimum regulatory capital requirements of large U.S. banking organizations and to help guide the agencies in adopting and implementing such standards in the United States. These standards were proposed by the Basel Committee on Banking Supervision in June 2004 and are available on the Committee's web site at www.bis.org. Participation in the study is voluntary, and completed responses are due to the agencies in January, 2005.

The Committee's proposal offers banking organizations several alternative methods for calculating regulatory capital requirements: a "standardized" approach and two versions of an internal ratings based (IRB) method, one referred to as the "foundation" approach and the other the "advanced" approach. In the United States, the agencies are considering adopting only the advanced approach and are evaluating only that approach in QIS-4. To do so, however, the participants are asked to measure their exposures and related capital requirements under both the advanced IRB method and current rules in order to identify differences in the requirements for the same or similar risks.
