Bank Size

This paper examines the impact of internal bank governance on bank liquidity creation in Iran during 2010-2017. We analyze whether banks with larger size and liquidity levels creates higher levels of liquidity. The results using panel GMM method show that corporate governance has a positive effect on liquidity creation; of course, it is not significant. Also, this effect is not affecting by bank size level, but a bank with higher liquidity levels have a higher elasticity to the governance change. Moreover, banks with higher financial stability have higher liquidity creation. Furthermore, the equity ratio index harms liquidity creation, which means “the fragility hypothesis” is confirmed within Iranian banks.

Corporate governance of banks is one of the most important structures required by banks to maintain the health and stability of banks, which can play an important role in managing banks' risk. This paper examines the effect of corporate governance on liquidity risk management, credit risk management, and total bank risk management. We used board structure effectiveness, transparency, and responsibility as corporate governance indicators. The financial ratio approach is also used to measure risk management. The period under review was 2006-2018. In addition to corporate governance criteria, other explanatory variables affecting banks' risk management have also been used. This paper used the performing unit root, cointegration, and F-Limmer tests to ensure panel estimation. Given the impact of past banks' risk management on current risk management, this variable has also been modeled as an explanatory variable. For this reason, the GMM method has been used to estimate the models in question. Given the importance of bank size in corporate governance on bank risk management, Banks are divided into large and small groups, so the effect of corporate governance in large and small banks has also been investigated on bank risk management. The results show that compliance with corporate governance criteria positively affects banks' risk management. However, due to weak corporate governance in large banks, corporate governance in large banks hurts bank risk management.
