Risk and risk-based capital of US bank holding companies

This paper analyzes banks' capital and risk-based capital (RBC) ratios as predictors of risk. Using quarterly data on U.S. bank holding companies (BHCs) from 1997 through 2010, we regress the capital and RBC ratios against six balance-sheet and market-based indicators of risk. Although the capital and RBC ratios are statistically significant predictors of BHCs' levels of risk, we find the capital ratio is a statistically significantly better predictor of risk than the RBC ratio. This difference is strongest since the recent financial crisis beginning in 2007.
