What is hyperinflation?

Updated 10 July 2026 Part of Inflation

Hyperinflation is inflation so fast and severe that money stops doing its basic job. Prices rise, but the deeper problem is trust: people no longer believe the currency will hold value between earning it and spending it. Unlike moderate inflation, where money still works and prices move in a broadly predictable way, hyperinflation turns the currency into something people try to get rid of as quickly as possible. It usually begins when a government loses fiscal discipline, cannot cover its spending through normal revenue or borrowing, and relies on money printing to fill the gap. That extra money does not create extra goods. It weakens confidence, pushes prices higher, and can damage savings, wages, trade, contracts, and daily life.

How hyperinflation begins

Hyperinflation usually starts with a government finance problem. A state spends more than it can raise through taxes or borrowing. If lenders lose faith, the government may turn to the central bank to create money so bills can still be paid.

Money printing is not always harmful in itself. Economies need enough money to support ordinary trade and growth. The danger comes when new money is created mainly to cover a fiscal hole, while the supply of goods and services does not rise with it. More currency is chasing the same real output.

At first, this may look like high inflation. The break comes when people decide the currency itself is unsafe. Workers want to spend wages quickly. Sellers raise prices because they expect their costs to rise again. Lenders avoid long repayment terms. Foreign currency, durable goods, or barter may become more attractive than local money.

That change in behaviour matters because hyperinflation feeds on expectations. If people believe money will lose value, they act in ways that make it lose value faster.

How it differs from moderate inflation

Moderate inflation means prices rise over time, but the currency still works. People accept it in payment. Shops can set prices. Employers can agree wages. Savers may lose some purchasing power if returns do not keep up, but money remains useful for planning.

Hyperinflation is different in kind, not just degree. The currency stops being a reliable store of value, meaning it no longer preserves purchasing power well enough for normal saving. It also becomes a weaker medium of exchange, meaning people become less willing to accept it in payment.

That is why confidence sits at the centre of hyperinflation. Prices are the visible symptom. The failure of money is the underlying condition.

What hyperinflation does to an economy

Hyperinflation harms people unevenly. Those paid in cash, living on fixed incomes, or unable to move into safer assets suffer most. Savings built up over years can lose purchasing power before households have time to react.

Businesses struggle because normal calculation breaks down. A price set in the morning may not cover replacement costs later. Suppliers may refuse local currency. Contracts become harder to write because future payments may be worth far less than expected. Investment slows because planning becomes guesswork.

The fiscal problem can also deepen. As formal business weakens, tax collection becomes harder. If the government keeps relying on newly created money, the cycle continues: more money printing, weaker confidence, higher prices, and still less trust.

The social damage can last after prices stabilise. People lose faith in public institutions, banks, contracts, and sometimes in the idea of the national currency itself. Ending hyperinflation usually requires restoring fiscal discipline, limiting money creation, and rebuilding trust that money will hold value long enough to use.
