Investigating theEeffects of Factors on CapitalAdequacyRatio in the Islamic BankingSystem of Iran and Malaysia

Capital adequacy ratio is one of the most important indicators in analyzing the situation of banks in order to manage banks against risks such as bankruptcy and their inability to meet obligations. This controls the risk management of banks. Therefore, the present study, investigates the effect of banking variables on the capital adequacy ratio in private banks in Iran during the period 1397-1390 and in Malaysia during the period 2012-2019 by the generalized moment method (GMM). The results show that in the Iranian banking system, credit risk and return on assets have a direct effect on bank size, financial leverage and liquidity have a negative effect on the capital adequacy ratio. In the Malaysian banking system, financial leverage, liquidity ratio and credit risk have a positive effect and the share of deposits and return on assets has a negative effect on the health index. The difference in the effectiveness of variables is due to different methods of financing the banking system and maintaining the vision of investment projects.
