Bretton Woods system
The Bretton Woods system of monetary management established the rules for commercial and financial relations among the world's major industrial states. The Bretton Woods system was the first example of a fully negotiated monetary order intended to govern monetary relations among independent nation-states. The Bretton Woods Agreements was signed in 1944 by 44 nations. And the agreement lasted until 1971, when President Nixon overturned the Bretton Woods agreement and established a floating exchange rate for the major currencies.
The chief features of the Bretton Woods system were an obligation for each country to adopt a monetary policy that maintained the exchange rate of its currency within a fixed value plus or minus one percent in terms of gold and the ability of the IMF to bridge temporary imbalances of payments. In the face of increasing financial strain, the system collapsed in 1971, after the United States unilaterally terminated convertibility of the dollars to gold. This action caused considerable financial stress in the world economy and created the unique situation whereby the United States dollar became the "reserve currency" for the states which had signed the agreement.
