Regulation, bank capital, and bank risk: evidence from the Lebanese banking industry

Abstract

This paper analyzes the relationship between change in capital and change in risk for a sample of 23 Lebanese banks between 2009 and 2014. Using the simultaneous equations model, our evidence reveals that banks determine their capital and risk levels simultaneously, with a negative relationship. While banks adjust their capital rapidly, they adjust their risk slowly. Furthermore, undercapitalized banks adjust their capital levels more rapidly than well-capitalized banks, and they increase their capital when they decrease their risk. However, there is no conclusive evidence regarding the role of regulatory pressure in driving risk-taking behavior. Finally, there are no major differences in the relationships between capital and risk regardless of whether banks are listed or not.
