The Internal Audit Function in Banks

The Basel Committee on Banking Supervision (the Committee) is issuing this revised supervisory guidance for assessing the effectiveness of the internal audit function in banks, which forms part of the Committee’s ongoing efforts to address bank supervisory issues and enhance supervision through guidance that encourages sound practices within banks. The document replaces the 2001 document Internal audit in banks and the supervisor’s relationship with auditors. It takes into account developments in supervisory practices and in banking organisations and incorporates lessons drawn from the recent financial crisis.
