Corporate governance and credit rating in Islamic banks: Does Shariah governance matters?

We investigate whether Islamic banks with strong corporate governance benefit from higher credit ratings relative to Islamic banks with weaker governance and whether Shariah governance can affect the credit ratings of Islamic banks or not. We document, after controlling for Islamic bank-specific risk characteristics, that credit ratings are negatively associated with the number of blockholders, CEO power, the supervisory role of the Shariah board and investment deposits; and positively associated with share listing ownership, board independence, women directors, board directors expertise and Shariah board expertise. As well as, credit rating is higher for Southeast Asian Islamic banks and weaker for GCC Islamic banks.
