This study examines the impact of bank size on bank regulatory capital ratios and risk-taking behavior using a panel dataset of 30 Bangladeshi commercial banks over the period 2008-2012.The relationship between bank regulatory capital ratios and bank risk-taking is also examined.For empirical analysis, generalized methods of moments (GMM) panel method are used to explore the relationships among bank size, regulatory capital ratios and risk-taking behavior.Empirical results show that large banks hold lower amount of capital and take higher level of risk.Findings also show a reverse relationship between bank capital levels and bank risk-taking; that is, banks holding higher levels of regulatory capital are significantly less risky.Findings of this study has important implications for the Bangladeshi government, policy makers, banking regulators and bank stakeholders regarding bank size, regulatory capital requirements and overall banking sector risk-taking behavior.
