Money & Economic Foundations

A rule that wouldn't bend.

Under a gold standard a unit of currency stood for a defined amount of gold. That single constraint is the whole story — both halves of it.

The problem

You're at the desk when the shock hits.

Capital is leaving the country and gold is flowing out with it. Do something.

The definition

One constraint, three consequences.

Hands on

The economy grows. The gold doesn't.

Reserves stay where they are. Drag up what the economy needs.

Reserves and needs are matched. The constraint isn't binding yet.

The verdict

Neither perfect nor simply a failed relic.

Both columns were true at the same time. That's why it lasted, and why it went.

What it delivered

Money couldn't be created at will — the supply was tied to a scarce physical good.
Overspending risked people converting to gold, which pressured governments to be careful.
Currencies tied to the same metal held steadier exchange rates against each other.
That made cross-border trade, investment and long contracts easier to plan.

What it cost

Little room to respond in a crisis — new money questioned the backing.
If the economy grew faster than gold did, the system came under strain.
Gold flowing abroad forced rate rises that slowed activity further.
Prices still moved and crises still happened. The link was never a guarantee of stability.
