Nixon shock

The Nixon shock was a series of economic measures undertaken by United States President Richard Nixon in 1971, the most significant of which was the unilateral cancellation of the direct international convertibility of the United States dollar to gold.

While Nixon's actions did not formally abolish the existing Bretton Woods system of international financial exchange, the suspension of one of its key components effectively rendered the Bretton Woods system inoperative. While Nixon publicly stated his intention to resume direct convertibility of the dollar after reforms to the Bretton Woods system had been implemented, all attempts at reform proved unsuccessful. By 1973, the Bretton Woods system was replaced de facto by a regime based on freely floating fiat currencies that remains in place to the present day.

In 1944 in Bretton Woods, New Hampshire, representatives from 44 nations met to develop a new international monetary system that came to be known as the Bretton Woods system. Conference members had hoped that this new system would “ensure exchange rate stability, prevent competitive devaluations, and promote economic growth." It was not until 1958 that the Bretton Woods system became fully operational. Countries now settled their international accounts in dollars that could be converted to gold at a fixed exchange rate of $35 per ounce, which was redeemable by the U.S. government. Thus, the United States was committed to backing every dollar overseas with gold. Other currencies were fixed to the dollar, and the dollar was pegged to gold.

For the first years after World War II the Bretton Woods system worked well. With the Marshall Plan, Japan and Europe were rebuilding from the war, and countries outside the US wanted dollars to spend on American goods—cars, steel, machinery, etc. Because the U.S. owned over half the world's official gold reserves—574 million ounces at the end of World War II—the system appeared secure.
