Bolivia
1984–1985

When the foreign credit of the 1970s stopped and tin prices fell, Bolivia's government kept spending and paid with the central bank.

Currency reform: 1 boliviano = 1,000,000 pesos (1987) · Cause: Debt crisis, a deficit paid by the central bank · Resolution: Decree 21060 (Aug 1985): free exchange rate, budget cuts

In short

Hyperinflation ran from April 1984 to September 1985 and peaked at 183 % in February 1985, prices doubling every 20.3 days (H&K). The central bank could not print notes fast enough and issued bank cheques (cheques de gerencia) as cash. Decree 21060 of August 1985 (the "New Economic Policy") stopped it within weeks.

Context: why it happened

  • The debt crisis. Foreign lending stopped in the early 1980s, while the state kept spending.

How it ended

A classic shock: an exchange rate set by the market, a budget balanced by cutting spending and raising state fuel prices, and the central bank stopped financing the state.

Consequences & lessons

  • When a central bank issues cheques because notes cannot be printed fast enough, the money has already escaped its control.
