Corporate governance for banks is of a great importance to both the supervisory authorities and international and regional organizations as well. A set of international publications have been issued on the standards and guidelines on corporate governance for banks. Considering its importance and significance to the financial sector, corporate governance guidelines and standards are adopted by supervisory authorities. Most known relevant publications are those issued by Basel Committee on Corporate Governance principles for banks, and publication issued by the (OECD). It is worth mentioning that QCB has issued guidelines on corporate governance in Instructions to Banks book, and guidelines on corporate governance for financial institutions in 2008. In view of the recent regulatory and international requirements and publications following the financial crisis, more responsibilities and wider role have been assigned to banks by regulators and all stakeholders. As such QCB is issuing a revised version of corporate governance principles including recent update thereof.
