There is a tenuous predictive relationship between the ratio of nonfinancial credit to GDP and GDP two years ahead. Setting bank capital requirements following a simple rule based on the credit-to-GDP ratio is not a good idea in our model even if the model encapsulates a predictive relationship in line with the observed data.
Rules that respond to cyclical conditions fail to prevent excessive risk taking, whereas a static capital buffer performs nearly as well as the Ramsey rule.
By examining the reaction of different asset prices, we find evidence that market participants value the stress test announcements not only for the information on possible future capital distributions but also for the signals about bank resilience. These results back the use of stress tests by central banks to inform the broader public about the soundness of the banking system.
