Corporate governance and the financial performance of commercial banks in Ghana

Abstract

This study aims to provide further evidence on the effect of corporate governance on the performance of Ghanaian banks. Two performance measures were used in this study, namely: Return on Asset (ROA) and Cost-Income Ratio (CIR). Data for the analysis were sourced from 21 commercial banks from 2005 to 2015. Regression estimation techniques were employed for analysis purposes. The result revealed that large board size reduces banks’ performance. Furthermore, CEO duality and foreign ownership negatively affect the performance of banks. However, while the effect of CEO duality was significant on CIR, it was not significant in the case of ROA. On the contrary, the effect of foreign ownership was only significant on ROA.  Moreover, board independence has a significant positive effect on both CIR and ROA, while audit committee independence has no significant effect on CIR and ROA. The paper argues that for a good corporate governance practice, banks should institute a small board with more than half of the members being independent directors. Furthermore, the role of the board chair should be separated from that of the managing director/CEO. The study provides insight and further evidence to stakeholders and regulators to deal with the crisis in the Ghanaian banking sector.
