One of the requirements of the Federal Deposit Insurance Corporation Improvement Act (FDICIA) was that bank regulators establish capital ratio zones that mandate prompt corrective action (PCA) and early intervention in troubled banks. However, prior research suggests that increases in regulatory capital standards can lead to offsetting increases in risk. This paper develops and estimates a 3SLS model to examine the simultaneous impact of PCA on both bank capital and credit risk. The results document that the FDICIA was effective in that, subsequent to its passage, US banks increased their capital ratios without offsetting increases in credit risk.
