when did us dollar not backed by gold
History of the United States dollar In 1971, President Richard Nixon unilaterally ordered the cancellation of the direct convertibility of the United States dollar to gold. This act was known as the Nixon Shock.
Gold standard This was meant to be a temporary measure, with the gold price of the dollar and the official rate of exchanges remaining constant. Revaluing currencies was the main purpose of this plan. No official revaluation or redemption occurred. The dollar subsequently floated. In December 1971, the “Smithsonian Agreement” was reached. In this agreement, the dollar was devalued from $35 per troy ounce of gold to $38. Other countries' currencies appreciated. However, gold convertibility did not resume. In October 1973, the price was raised to $42.22. Once again, the devaluation was insufficient. Within two weeks of the second devaluation the dollar was left to float. The $42.22 par value was made official in September 1973, long after it had been abandoned in practice. In October 1976, the government officially changed the definition of the dollar; references to gold were removed from statutes. From this point, the international monetary system was made of pure fiat money.

Gold standard Many other countries followed Britain in returning to the gold standard, this was followed by a period of relative stability but also deflation.[24] This state of affairs lasted until the Great Depression (1929–1939) forced countries off the gold standard. In September 19, 1931, speculative attacks on the pound forced Britain to abandon the gold standard. Loans from American and French Central Banks of £50,000,000 were insufficient and exhausted in a matter of weeks, due to large gold outflows across the Atlantic.[25][26][27] The British benefited from this departure. They could now use monetary policy to stimulate the economy. Australia and New Zealand had already left the standard and Canada quickly followed suit.
