The global foreign exchange market operates within an international monetary system overseen by supranational institutions, primarily the International Monetary Fund (IMF). The IMF monitors global balance of payments stability, provides emergency financing to countries facing currency crises, and manages global reserve assets.

The IMF’s primary reserve asset is the Special Drawing Right (SDR). The SDR is not a physical currency; it functions as a potential claim on the freely usable currencies of IMF member states.
