The International Monetary Fund (IMF) plays a substantial regulatory role in the international monetary and financial system. The IMF has been assigned a formal regulatory role in a limited number of areas such as obligations covering exchange rate policies. The Fund has a broader informal regulatory role derived from the voluntary consent of its members such as in surveillance over members’ financial sector policies and international payments imbalances. The IMF’s regulatory role is unlike that of its member governments within their own jurisdictions. The Fund’s formal and informal regulation must be constantly nurtured and renewed via peer-review processes.
