Gold Standard

The gold standard was a fixed exchange rate system in which each currency’s value was defined by a fixed amount of gold, and the central bank stood ready to exchange currency for gold on demand. It provided price stability and discipline but collapsed during crises. The UK abandoned gold in 1931; the US formally ended the gold standard in 1971.

How the gold standard worked

Under the gold standard, a government fixed the price of its currency in terms of gold. The pound sterling was worth 113 grains of gold. The US dollar was worth 15.5 grains of gold. This fixed the USD/GBP exchange rate: 113 ÷ 15.5 = 7.3 dollars per pound.

If a holder of dollars wanted gold, the US central bank (or the Treasury) would redeem them at the fixed rate: bring $20.67 and receive one ounce of gold. If a holder of pounds wanted gold, the Bank of England would do the same.

The central bank had to hold gold reserves sufficient to back the currency in circulation. If a bank issued more currency than it had gold, it would quickly fail when citizens came to redeem.

Automatic exchange-rate stabilization

The gold standard maintained fixed exchange rates automatically. If USD/GBP tried to rise above 7.3 (more dollars per pound), an arbitrageur could:

1. Buy one pound for 7.20 dollars (cheaper than the fair rate).
2. Redeem the pound for gold (at the Bank of England).
3. Redeem the gold for dollars in the US (at 15.5 grains per $1).
4. Pocket the difference (20.67 − 7.20 = 13.47 dollars profit, minus transaction costs).

This gold arbitrage ensured rates stayed near the fixed level.

Price stability and discipline

The gold standard provided long-run price stability. Inflation was constrained by the growth of the gold supply. If prices rose without rising production, the real value of gold reserves would fall, forcing a central bank to contract the money supply to maintain redemption ability.

This discipline was seen as a virtue: governments and central banks could not inflate or run deficits without depleting gold reserves. Fiscal discipline was automatic.

The cost: rigidity in crises

The gold standard’s fatal flaw was rigidity. During recessions, the standard required central banks to contract the money supply (to maintain gold redemption levels as gold flowed out), worsening the recession.

The Great Depression was catastrophic under the gold standard. As the crisis hit, investors lost confidence and demanded gold. Central banks had to contract money and raise interest rates to defend their gold reserves. This made the recession worse. Countries were trapped: they could not print money to stimulate demand without violating the gold standard.

Collapse during the Great Depression

The UK abandoned gold in 1931 (the pound depreciated, but the economy recovered faster). The US abandoned gold during the New Deal (1933). By the late 1930s, most countries had abandoned the gold standard. Those that abandoned it soonest recovered soonest.

The gold standard did not make a full comeback after WWII. Instead, the Bretton Woods system was created: the US dollar was pegged to gold, and other currencies were pegged to the dollar. This was a compromise — still discipline, but with some flexibility.

The end of gold convertibility

In 1971, the US formally abandoned gold. The Fed could no longer redeem dollars for gold at the fixed rate. This ended the last vestige of the gold standard for major currencies.

Most economists view this as necessary: the gold standard’s constraints were incompatible with modern macroeconomic needs. But some advocates argue the gold standard prevented the inflation and instability of the post-1971 era.

Modern gold bugs

Some economists and investors believe the world should return to a gold standard (or at least a commodity standard of some kind). They argue it would prevent inflation and require fiscal discipline.

Most mainstream economists disagree, arguing that the gold standard is impractical (the gold supply cannot match economic growth) and unnecessarily constrains policy. The consensus is that modern floating-rate systems with inflation targeting provide better outcomes.
