This study examines the impact of multi-layer governance mechanisms on the level of bank risk disclosure. Using a large dataset from 14 Middle East and North Africa (MENA) countries over a period of 8 years, our findings are threefold. First, our results suggest that the presence of a Sharia supervisory board is positively associated with the level of risk disclosure. Second and at the bank-level, we find that ownership structures have a positive effect on the level of risk disclosure. At the country-level, our evidence suggests that control of corruption has a positive effect on the level of bank risk disclosure. Our study is, therefore, a major departure from much of the existing accounting literature that offers new crucial insights that show that firms' disclosure choices are not mainly shaped by firm-level (internal) governance arrangements, but also country-level (external) governance and religious factors. Our findings have important implications for corporate boards, investors, regulatory authorities, standards-setters and governments relating to the development, implementation and enforcement of corporate and national governance standards.
