The International Monetary Fund (IMF) plays a substantial regulatory role in the international monetary and financial system. It has been assigned a formal regulatory role in a limited number of areas, such as obligations covering exchange rate policies. Yet 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. This regulatory role is unlike that of its member governments within their own jurisdictions. In order to guide the global economy in the wake of the 2007–09 crisis, the Fund's formal and informal regulation will have to be constantly nurtured and renewed via peer-review processes.
