What is the gold standard?
The gold standard is a monetary system in which a country's currency can be exchanged for a fixed weight of gold at a price set by the state.
Under it, the central bank or treasury promises to buy and sell gold at that official price. Banknotes work like a claim on gold. The money supply is limited by how much gold the authority holds.

Worked example (hypothetical)
Suppose Country A defines its note as equal to a set weight of gold. Country B defines its own note as equal to a larger weight of gold.
- Both notes are tied to gold, so they are tied to each other.
- The exchange rate between A and B is the ratio of their gold weights. It does not float.
- If B's note started trading too cheaply in A, a trader could buy B's notes, convert them into gold in B, ship the gold to A and convert it into A's notes for a profit. That arbitrage pushes the rate back to the gold ratio.
- The rate can only move within a narrow band set by the cost of shipping and insuring gold. These limits were called the "gold points".
This is why gold-standard countries had fixed exchange rates without needing a separate peg.
Formal definition and variants
For experienced readers, a strict gold standard has these features:
- A fixed mint parity: an official price of gold in the national currency.
- Convertibility: the authority exchanges notes for gold on demand.
- Free movement of gold in and out of the country.
Variants:
| Variant | How convertibility worked |
|---|---|
| Gold specie standard | Gold coins circulate; notes convertible into coins |
| Gold bullion standard | Notes convertible only into large gold bars, not coins |
| Gold exchange standard | Reserves held partly in a currency that is itself convertible into gold |
The Bretton Woods system was a gold exchange standard. Other currencies were pegged to the US dollar, and the dollar was convertible into gold only for foreign official holders, not for the public.
Edge cases:
- Suspension: governments often stopped convertibility in war or crisis, then sometimes restored it.
- Parity changes: changing the official gold price is a devaluation or revaluation.
- Partial backing: most systems did not hold gold equal to all notes in circulation. They held a fraction as cover, similar in logic to fractional reserve banking.
- Adjustment: a country with a trade deficit lost gold, its money supply shrank and prices fell. This links the gold standard to deflation during slumps.
Gold standard history in brief
The classical gold standard spread among major economies in the industrial era. It broke down around the world wars and the Great Depression, when countries left gold so they could expand money and credit. Bretton Woods brought a limited gold link back after the Second World War. That link ended when the United States stopped converting dollars into gold. Since then major currencies have been fiat money, backed by law and central bank policy rather than by metal.
Where the term appears today
- News and politics: debates about "returning to the gold standard", and commentary on central bank gold buying.
- Central bank reports: gold appears as part of official reserves. It is no longer a convertibility promise.
- Trading platforms: gold is quoted as a floating price, for example XAUUSD in MetaTrader 5. Under a strict gold standard the dollar price of gold would not move this way. See Gold and Metals.
- Everyday speech: "the gold standard" also means "the reference benchmark", which is unrelated to money.

Frequent questions
What does "gold standard" mean in simple words?
It means money that the state promises to exchange for a fixed amount of gold.
Does any country use the gold standard now?
No major economy does. Today's currencies are fiat money. Central banks still hold gold as a reserve asset.
Is a currency board the same as a gold standard?
No. A currency board fixes the local currency to a foreign currency and backs it with that currency's reserves, not with gold.
Why did countries leave the gold standard?
It limited how far they could expand money in crises and passed deflation from one country to another through gold flows.
