Cut loose
S&P 500 98.76 · +3.07 · +3.21%
Sunday night a president untied the dollar from gold; Monday the market threw a party for the end of its own anchor. The tether is off and the first sensation is lift.
The day's protagonist
The dollar — no symbol.
Move: untied from gold after thirty-seven years at $35 an ounce
At nine o'clock Sunday night, pre-empting Bonanza, Richard Nixon announced three measures in sixteen minutes: a ninety-day freeze on wages and prices, a ten percent surcharge on imports, and the suspension of the dollar's convertibility into gold — the promise that had anchored the world's money since 1944. It was announced as temporary. It never came back. Monday morning the market cheered the loudest it ever had: the biggest Dow gain in history to that date, on the heaviest volume the exchange had ever seen. From that morning on, every dollar has been backed by exactly what the tape decided it could live with: trust.
The deeper account
Bretton Woods, 1944: the world's currencies pegged to the dollar, the dollar pegged to gold at $35 an ounce. By 1971 the promise exceeded the gold: dollars abroad far outnumbered the metal in Fort Knox, and the run had quietly begun.
The announcement was staged for maximum Sunday-night reach — the address famously pre-empted Bonanza. The freeze read as decisive; the window's closing read, to most viewers, as a technicality.
The photograph of this day is Floats', not his: the hand just opened, the gold balloon at the instant it became unreachable — not the reaching, and not the gone. The crowd streamed past on its way to the loudest party the tape had ever thrown, and nobody looked up.
Within two years every major currency floated. Gold, freed from thirty-five dollars, never looked back. The 'Nixon Shock' became the founding condition of every page in this encyclopedia that follows it.
The record gain is kept in the ledger — the odd ceremony of a market celebrating the end of its own anchor. What was actually recorded that Monday took decades to read.
The artifact
The promise had anchored the world's money since 1944: thirty-five dollars, an ounce of gold, on demand. Sunday night at nine — pre-empting Bonanza — the window closed in sixteen minutes of television, announced as temporary alongside a wage freeze and an import surcharge. Monday the market threw a party for the end of its own anchor: the biggest Dow gain to that date on the heaviest volume the Exchange had ever seen. The card is still up.
