Risk-return analysis of Islamic banks’ investment deposits and shareholders’ fund

Abstract

The purpose of this paper is to study the differences or variance in the yields of Islamic and conventional bank deposits and capital, respectively, in view of their contractual differences, namely the former which is based on equity and the latter on debt. The paper uses a financial ratio approach. It was found that deposit yields in conventional banks were lower than return on equity (ROE), which truly reflect the contractual differences between fixed deposit and bank’s capital. Also, it was found that Islamic banks’ deposit yield and ROEs do not reflect their risk-taking properties, as their variances were found to be smaller.
