Nixon Shock
President Nixon's 1971 unilateral decision to end the dollar's convertibility to gold, ending the Bretton Woods system and making the US dollar a pure fiat currency backed by faith and military power rather than gold reserves.
On August 15, 1971, Nixon announced on television that the US would no longer convert dollars to gold at the fixed rate of $35/ounce. This 'closing of the gold window' ended the Bretton Woods system that had organized the global economy since 1944.
The cause was structural: the US was running massive deficits (Vietnam War, Great Society programs) and printing dollars to cover them. By 1971, the total dollars held globally far exceeded US gold reserves, if all holders had simultaneously demanded gold, the US could not have delivered. France had already begun converting dollars to gold, accelerating the crisis.
The consequence: the dollar became a pure fiat currency, valuable because the world uses it, not because it's backed by anything tangible. The US retained the reserve currency status not through gold but through: oil pricing in dollars (petrodollar system, 1977), US military control of global shipping lanes, and the absence of alternatives. The Bretton Woods gold standard became the Pax Americana dollar standard, more durable but more psychologically fragile.
