FSB member jurisdictions have committed to undergo periodic peer reviews focused on the implementation and effectiveness of international financial standards and policies agreed within the FSB. In addition to being a condition of FSB membership, peer reviews are an important institutional mechanism to promote full, timely and consistent implementation of agreed G20/FSB financial reforms and are a means of fostering a ‘race to the top’ in terms of adherence to standards. The Handbook for FSB Peer Reviews (Handbook) was originally prepared in December 2009 by the FSB Standing Committee on Standards Implementation (SCSI) to develop a framework for FSB peer reviews. It was further revised in 2011, 2014, 2015 and 2017 in response to SCSI members’ suggestions on ways to further enhance the functioning of peer reviews.
