Abstract: This study analyses how capital influences profitability and risk in the context of Islamic and conventional banking in Gulf Cooperation Council (GCC) countries. It achieves this through structure-conduct-performance, moral hazard, and regulatory hypotheses. We apply the generalised method of moments (GMM) technique for dynamic panels using bank-level data from 85 banks for the 2003-2011 period. We first found that highly capitalised Islamic banks generate low profitability, while in contrast, highly capitalised conventional banks generate high profitability. Secondly, we found highly capitalised GCC banks (both Islamic and conventional) to be characterised by greater risk. Additionally, all profitability and risk variables demonstrate persistence. We then ultimately arrive at the same conclusions about capital, profitability, and risk relationship with the introduction of regulatory variables.
Keywords: bank capital; profitability; risk; Islamic finance; dynamic panel; financial regulation.
