Gold-backed currency

For a golden century or so, the world ran on a simple promise: every note a government issued could be swapped for a fixed weight of gold. Money was paper for convenience, but gold in substance. This was the classical gold standard.

The rules of the game

Under a gold standard, a country defines its currency as a fixed amount of gold — say, a dollar equals so many grains. Anyone can, in principle, take notes to the treasury and redeem them for the metal. Because currencies were all pegged to gold, they were effectively pegged to each other, and exchange rates barely moved. From roughly 1870 to 1914, most of the trading world operated this way.

Why people loved it: discipline

The gold standard put a hard limit on governments. You couldn’t simply print money to fund a war or a spending spree, because every note had to be backed by real gold you actually held. If you printed too much, people would redeem notes for gold, your reserves would drain, and you’d be forced to stop. Money you can’t print at will tends to hold its value — this era saw prices stay remarkably stable over decades.

“The gold standard doesn’t restrain the people. It restrains the government. That is exactly why governments dislike it.”

Why governments came to hate it

That same discipline was a straitjacket in a crisis. In a war or a depression, a government’s deepest wish is to spend far more than it has — and the gold standard says no. It also meant a country couldn’t easily cushion a downturn by expanding money and credit. When the pressure became unbearable — world wars, the Great Depression — governments suspended or abandoned convertibility so they could print.

The twentieth century decisively chose flexibility over discipline. Step by step — through two world wars, the Depression, Bretton Woods, and finally 1971 — the gold anchor was loosened and then cut entirely. What replaced it is money backed by nothing but law and trust: fiat currency, next.
