Quizplus · Accepted Answer

The Bretton Woods System was an exchange rate system in which the value of the US dollar was fixed to gold at a rate of $35 per ounce, and other currencies were fixed to the dollar. However, the dollar was redeemable for gold only if presented by a foreign central bank. This meant that the US was committed to maintaining the value of the dollar by buying and selling gold as necessary to maintain the fixed exchange rate.
