summary
This entry tracks three monetary regime changes that bracket the modern era: (1) Lincoln's greenbacks (1862) — the first sovereign U.S. fiat issuance; (2) Bretton Woods (1944) — the post-war system pinning all major currencies to a gold-convertible U.S. dollar; and (3) the Nixon Shock (August 15, 1971) — the unilateral U.S. cancellation of dollar-to-gold convertibility, ending the gold standard and converting the world's reserve currency to fiat.
1862 — lincoln's greenbacks
February 25, 1862. Treasury Secretary Salmon P. Chase, with the Civil War treasury empty and New York bankers unwilling to extend further loans on tolerable terms, championed the First Legal Tender Act. Congress authorized $50 million (later expanded to $450 million) in United States Notes — printed in green ink and dubbed "greenbacks." They were not redeemable for gold or silver. They were legal tender by act of Congress, period.
This was politically radical. The financial press warned of "subversive" currency and runaway inflation. Bankers organized opposition. Chase himself was a personal hard-money advocate who had to override his own conviction. The greenback ultimately financed the Union's victory and demonstrated, definitively, that the federal government could issue currency without private banking intermediation. The implication was not lost on the banks; the political fight to recapture monetary control led, half a century later, to Jekyll Island and the Federal Reserve Act.
1944 — bretton woods
July 1944. Forty-four Allied nations meet at the Mount Washington Hotel in Bretton Woods, New Hampshire, to design the post-war international monetary system. Outcome: foreign currencies pegged to the U.S. dollar at fixed exchange rates; the U.S. dollar pegged to gold at $35 per ounce; foreign central banks could redeem dollars for gold at that rate from the U.S. Treasury. The IMF and the World Bank were created at the same conference. The U.S. dollar became the world's reserve currency by international agreement.
1971 — the nixon shock
August 15, 1971. President Nixon delivered a televised announcement of his "New Economic Policy," which included:
- Unilateral cancellation of dollar-gold convertibility for foreign central banks. The U.S. would no longer redeem dollars for gold at $35/oz, or any rate.
- A 90-day wage and price freeze.
- A 10% surcharge on imports.
The trigger: by 1971 the U.S. did not have enough gold to cover the dollars in circulation at $35/oz. On August 11, Britain had requested the transfer of $3 billion in gold from Fort Knox to the Federal Reserve in New York. Paul Volcker, then Undersecretary of the Treasury, later said: "If the British, who had founded the system with us, and who had fought so hard to defend their own currency, were going to take gold for their dollars, it was clear the game was indeed over."
Nixon framed the move as temporary. It was not. By March 1973, the major currencies were floating against the dollar, and the post-Bretton Woods era of fully fiat international currencies had begun.
consequences
- From August 1971 forward, no major currency in the world has been backed by anything other than the issuing government's word.
- Money supply expansion ceased to be physically constrained by gold reserves. The U.S. dollar M2 grew from ~$685 billion in 1971 to ~$21 trillion by 2025 — a 30x increase.
- The 1970s saw severe inflation; the 1980s saw the Volcker shock to break it; the 2008 and 2020 crises saw central-bank balance-sheet expansion at scales not previously imaginable under a gold-constrained system.
- Bitcoin's 2009 launch was, on the founders' own stated terms, a response to the inflationary architecture made possible by 1971. Whether that response succeeds is a separate question.
why this matters to PRIOR
The 1971 closure of the gold window is the single largest monetary regime change in modern history, and most retail participants in 2026 markets have no living memory of any other system. The "fiat money" that 99% of crypto-twitter is denominated in is itself a 53-year-old experiment. Every cycle PRIOR indexes after 1971 occurs in this regime. Most participants don't know that.
"the gold window closed. the printer opened. it has not closed since."
