The Federal Reserve and Office of the Comptroller of the Currency (OCC) have issued the attached Supervisory Guidance on Model Risk Management, which is intended for use by banking organizations and supervisors as they assess organizations’ management of model risk. This guidance should be applied as appropriate to all banking organizations supervised by the Federal Reserve, taking into account each organization’s size, nature, and complexity, as well as the extent and sophistication of its use of models (as defined and discussed below).
