Hyperinflation

What Is Hyperinflation?

Hyperinflation is an economic condition in which prices rise very quickly and keep accelerating, so that the purchasing power of a currency erodes at an extreme pace. Ordinary inflation is a persistent but usually moderate increase in prices. Hyperinflation is far more severe. Economists often describe it as a situation where monthly inflation exceeds roughly 50 percent, a threshold popularized by the economist Phillip Cagan in his 1956 study of hyperinflation episodes. In such conditions, the value of money can change from one day to the next, and people try to spend it as quickly as possible.

How It Develops

Hyperinflation usually begins when a government or central bank pays for large spending by creating new money rather than through taxes or borrowing from the public. When the supply of money grows much faster than the output of goods and services, each unit of currency buys less. Prices rise, which can prompt people to expect further increases and demand higher wages or prices. This expectation can feed on itself. As confidence in the currency falls, people spend it faster, which pushes prices up further and reduces the amount of money people are willing to hold. Many historical episodes also involved war, political upheaval, or a collapse in tax revenue.

Effects and Why It Matters to Investors

Hyperinflation damages savings, fixed incomes, and contracts denominated in the local currency. Holders of cash and bonds with fixed payments can lose nearly all their value. Some investors turn to assets such as real estate, commodities, or foreign currencies that may keep value better, though outcomes vary and such moves carry their own risks. Many governments facing hyperinflation have also imposed price or currency controls, which can distort markets and create shortages. Investors studying a country's economic stability often watch money growth, fiscal deficits, and inflation expectations as early warning signs.
