How Gold Became Money and Why It Eventually Failed
Around the Block | May 21, 2026 — By William Sanchez Jr., Founder of A.W. Block
The gold standard ended not because gold failed as money, but because paper gold failed as an institution.
If gold failed, then the search for sound money is futile and fiat is the inevitable destination of all monetary evolution. If paper gold failed, if the problem was institutional rather than monetary, then the solution is sound money without institutional counterparty risk. Bitcoin is that solution. To understand why, you need to understand how gold actually worked, why it was sound, and precisely what broke it.
Why Gold Has Unique Monetary Physics
Every commodity that has ever been chosen as money has eventually been debased. Seashells, beads, salt, copper, silver: each lost its monetary role when technology made it cheaper to produce. The history of money is, in large part, a graveyard of debased monetary goods.
Gold survived this dynamic for a simple physical reason: it is virtually indestructible, and producing new gold from the earth is irreducibly difficult.
Ammous documents the property that distinguishes gold from every other monetary candidate. In seven decades of reliable data, annual gold supply growth has averaged around 1.5% and never exceeded 2%. Silver, by comparison, grows 5 to 10% annually. The 36% price spike in 2006 was a real-world stress test. Mining output that year dropped to 2,370 tons, 100 tons below 2005. It dropped another 10 tons in 2007. The geology does not respond to price signals the way other commodities do.
Gold’s purchasing power has been almost uniquely resistant to debasement through increased supply. No other mined commodity comes close.
The Gold Standard Era
By the late nineteenth century, the major trading nations had converged on gold as the foundation of their monetary systems. The classical gold standard, roughly 1870 to 1914, produced more than four decades of virtually uninterrupted global growth and prosperity, in Ammous’s words.
Under this system, currencies were defined as fixed weights of gold. All currencies were ultimately the same thing: gold. Cross-border trade carried no currency risk. Capital flowed freely between nations. Price levels were stable over long periods. Entrepreneurs could plan across decades with confidence in the monetary unit.
Nik Bhatia’s layered money framework explains the architecture. Gold was first-layer money: the base, the settlement asset, the reference point for everything above it. National currencies and banknotes were second-layer claims on gold. International trade was settled in gold. The system worked because the first layer was sound and not controlled by any single party.
The mechanism that built the second layer was fractional reserve banking. Banks that took gold deposits issued more notes than they held in reserves. This expanded the effective money supply beyond the gold base, and the gap between paper claims and physical gold was the structural fault line that eventually defaulted. Nineteenth-century communications technology accelerated the centralization: settlement networks pushed gold into central vaults because moving paper claims by telegraph was cheaper than moving bullion by ship.
The gold standard also worked because it imposed discipline on government spending. You cannot fund an unlimited war with gold if gold is in finite supply. World War I ended the gold standard and that fiscal discipline simultaneously.
Bretton Woods: The Incomplete Restoration
After the chaos of the interwar period (competitive devaluations, trade barriers, hyperinflations in Germany and elsewhere), the Allied powers gathered at Bretton Woods, New Hampshire in 1944 to design a new monetary order.
The system they created was a compromise. The dollar would be convertible to gold at $35 per ounce, the rate Roosevelt had set in 1934 after revaluing the dollar from the prior $20.67 peg, for foreign central banks. Other currencies would be fixed to the dollar. In theory, gold remained the anchor. In practice, the United States was granted an enormous privilege: the ability to print dollars that others had to hold as reserves.
Economist Robert Triffin identified the structural flaw in 1960. A reserve-currency country must run trade deficits to supply the world with the reserves it demands, which over time undermines confidence in the convertibility of those reserves. The system was engineered to fail. Charles de Gaulle’s France was among the first to act on the implication, redeeming dollars for gold throughout the 1960s. Gold reserves at Fort Knox began declining.
August 15, 1971
On a Sunday evening, President Nixon appeared on national television and announced that the United States would “temporarily” suspend the convertibility of dollars to gold.
The Bretton Woods system collapsed. Within two years, exchange rates were floating. Within a decade, inflation in the United States had reached double digits. The relationship between the dollar and any external standard of value had been severed.
Why did gold lose? Not because gold was bad money. Because gold was heavy, hard to transport, easy to seize, and required centralized custody to scale. The spatial salability problem, moving large quantities of value across great distances quickly, was solved by paper gold. Paper gold required institutions. Institutions can be captured.
Ammous’s conclusion: the fiat standard was not a conscious conspiracy to destroy sound money. It was a gradual response to a real problem, the difficulty of moving gold across space, solved by introducing counterparty risk. The counterparty eventually defaulted.
The Lesson Bitcoin Draws
If gold failed because of its spatial salability problem, because settling international transactions in physical gold required centralized custodians who could be captured, then the solution is a monetary good with gold’s intertemporal properties but without gold’s spatial limitations.
Bitcoin settles globally in roughly an hour at vanishingly low cost relative to the value transferred. No institution is in the chain. No custodian can be captured. No government can freeze the transaction. Gold, by contrast, requires physical transport, insurance, security, and weeks of time. Moving large quantities across borders during geopolitical tensions may be legally impossible.
Bitcoin’s supply is mathematically fixed by code enforced by tens of thousands of nodes worldwide. Gold’s supply is geologically constrained but institutionally vulnerable.
Bitcoin does not require custodians to scale globally. It is the custodian.
The gold standard died because it could not solve the spatial salability problem without introducing institutions. Bitcoin solves the spatial salability problem without institutions.
