 The system was a monetary order intended to govern currency relations among sovereign states, with the 44 member countries required to establish a parity of their national currencies in terms of the U.S. dollar and to maintain exchange rates within 1% of parity (a "band") by intervening in their foreign exchange markets (that is, buying or selling foreign money).The U.S. dollar was the only currency strong enough to meet the rising demands for international currency transactions, and so the United States agreed both to link the dollar to gold at the rate of $35 per ounce of gold and to convert dollars into gold at that price.Due to concerns about America's rapidly deteriorating payments situation and massive flight of liquid capital from the U.S., President Richard Nixon suspended the convertibility of the dollar into gold on 15 August 1971.
