Richard Nixon in 1971. 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.

Great Britain, France, Switzerland, the franc-zone countries, and some other countries did not change the gold content of their currencies.
