Bretton Woods refers to the international monetary system established by the United Nations Monetary and Financial Conference, held in Bretton Woods, New Hampshire, from 1 July to 22 July 1944. The conference produced two foundational agreements: the Articles of Agreement creating the International Monetary Fund (IMF) and those creating the International Bank for Reconstruction and Development (IBRD, now part of the World Bank Group). The resulting framework pegged member currencies to the U.S. dollar, which was itself convertible to gold at a fixed rate of $35 per troy ounce, creating a gold-exchange standard that governed international finance for nearly three decades.
The conference brought together 730 delegates from 44 Allied nations, operating under the shadow of the Great Depression and two world wars, both of which were associated in the minds of the architects with the collapse of the earlier gold standard and the competitive devaluations and trade barriers of the interwar period. The two principal architects were Harry Dexter White of the U.S. Treasury and John Maynard Keynes representing the United Kingdom. Their competing proposals - White's favoring U.S. creditor interests and a constrained lending facility, Keynes's favoring a more expansive international clearing union with automatic credit creation - were resolved largely in favor of the American position, reflecting U.S. economic dominance at the time. For a full account of the negotiations and antecedents, see Bretton Woods - History.
Under the Bretton Woods system, member countries maintained fixed but adjustable exchange rates relative to the dollar and were permitted to intervene in currency markets to defend those rates. The IMF provided short-term balance-of-payments financing; the IBRD focused on longer-term development lending. The system required the United States to maintain dollar-gold convertibility and sufficient gold reserves to back outstanding dollar liabilities held by foreign central banks. As U.S. external liabilities grew relative to gold reserves through the 1960s - a tension identified by economist Robert Triffin as the “Triffin dilemma” - confidence in convertibility eroded. On 15 August 1971, President Richard Nixon suspended gold convertibility unilaterally, an event commonly called the “Nixon Shock.” Attempts to restore a modified fixed-rate system via the Smithsonian Agreement (December 1971) failed, and by March 1973 the major economies had shifted to floating exchange rates. The IMF and World Bank survived and continued operating under revised mandates.
The Bretton Woods institutions - the IMF and World Bank - remain central to international finance and development policy. Their governance structures, conditionality requirements, voting weights (which reflect the original postwar distribution of economic power), and policy prescriptions are subjects of ongoing scholarly and political dispute. The desirability of returning to some form of fixed exchange rates, reforming or abolishing the IMF and World Bank, reducing dollar dominance in global reserves, and the appropriate role of international financial institutions in sovereign economies are all actively contested. See Bretton Woods - Debate.
There is broad consensus among economists that the Bretton Woods fixed-rate system formally ended between 1971 and 1973. The causes of its collapse, the net effects of its operation on global growth and stability, and the appropriate design of any successor framework remain subjects of scholarly disagreement.
