🔴 Every hyperinflation in history has one root cause: a central bank or monetary authority creating money at a rate far exceeding real economic growth. There are no exceptions in the Hanke-Krus table.
The Monetary Root Cause
Hyperinflation is not caused by supply shocks, foreign enemies, speculation, or greedy businesses — though all of these have been blamed at various times by governments trying to deflect responsibility. It is caused by excessive money creation. This is the consistent finding of the Hanke-Krus World Hyperinflation Table, which documents 62 episodes across 5 centuries of economic history.
Milton Friedman's dictum — "inflation is always and everywhere a monetary phenomenon" — applies with particular force to hyperinflation. Every one of the 62 episodes was preceded and accompanied by rapid money supply growth.
The Fiscal Origin
The deeper question is: why do governments create money so rapidly? The answer is almost always fiscal dominance — a government that cannot or will not control its spending and turns to the central bank to finance the deficit. This is the sequence:
- Government spends more than it collects in taxes
- Deficit is financed by borrowing from the central bank
- Central bank creates new money to lend to the government
- The new money causes prices to rise
- Prices rise faster, people spend money faster (velocity increases)
- The government needs even more money to pay bills
- The cycle accelerates into hyperinflation
Pre-Conditions and Warning Signs
Hanke identifies several pre-conditions that raise the risk of hyperinflation:
- Weak institutions: Central bank controlled by government; no independent monetary authority
- Fiscal imbalance: Large, persistent government deficits with no credible path to balance
- Loss of confidence: Dollarization begins as citizens voluntarily shift to hard currencies
- Political instability: War, regime change, or sanctions that disrupt normal fiscal constraints
- Collapsing exchange rate: The black-market premium on foreign currency widens sharply
⚠️ Warning Signal: When the black-market exchange rate for U.S. dollars begins climbing sharply against the domestic currency, hyperinflation is often 6–18 months away. Professor Hanke monitors these rates daily.
