We now have to determine whether these results arose from actual differences in risk among respondents, differences in stages of preparation (including data limitations) among respondents, limits of the QIS4 exercise, or a possible need for adjustments to the Basel framework itself.
Staff at the agencies are working together to analyze the QIS4 results and in some cases are talking to banks about their submissions. Analyzing the data used in QIS4 is vitally important, because ultimately the success of Basel II will depend on the quantity and quality of data that banks have to use as inputs to the framework.
