Using CAMEL ratings to evaluate regulator effectiveness at commercial banks

Abstract

This study uses the capital adequacy component of the CAMEL rating system to assess whether regulators in the 1980s influenced inadequately capitalized banks to improve their capital. Using a measure of regulatory pressure that is based on publicly available information, I find that inadequately capitalized banks responded to regulators' demands for greater capital. This conclusion is consistent with that reached by Keeley (1988). Yet, a measure of regulatory pressure based on confidential capital adequacy ratings reveals that capital regulation at national banks was less effective than at state-chartered banks. This result strengthens a conclusion reached by Gilbert (1991).
