This archive documents fiat currencies that lost most or all of their value since 1900. Search by country or currency name. History gives you context for your decisions — not predictions about what happens next.

What conditions appeared before most failures?
Four economic conditions showed up repeatedly before historical currency collapses. Their presence doesn't guarantee failure, but they appeared in the majority of documented cases.
Historical Precursors
Factors observed in many historical failures
Current Context
Major currency metrics for reference
| Currency | Debt/GDP | Real Rates |
|---|---|---|
| USD | ~124% | Variable |
| JPY | ~264% | Near-zero |
| EUR | ~90% | Variable |
Note: these factors alone don't predict outcomes. Many economies have carried high debt ratios for decades without currency failures.
What happened to the German mark in 1923?
The Weimar Republic hyperinflation is one of the most studied currency failures in history. Post-war debt, reparation payments, and money printing destroyed the mark's value in roughly 18 months.
Germany 1923
The Weimar Republic hyperinflation
Historical accounts document that Germans who held tangible assets — including gold — generally preserved buying power better than those who held only paper currency during this period.
Key Context
- —Post-WWI reparations created unsustainable fiscal pressures.
- —Currency printing accelerated to meet obligations.
- —Trust in the currency collapsed over roughly 18 months.
- —A currency reform and new monetary framework eventually stabilized the situation.
What are the limitations of this data?
Historical patterns give you context, but they don't predict what happens next. Four reasons to be careful with this record.
History doesn't repeat exactly
Every currency situation involves unique factors: political stability, institutional strength, economic resilience, and policy responses. Historical comparisons have limits.
Major currencies differ
The USD, EUR, and JPY have structural advantages — reserve status, deep markets, institutional credibility — that historical failure cases typically lacked.
Gold has limitations too
Gold doesn't produce income, has storage costs, and can underperform for long stretches. From 1980 to 2008, gold lost value in real terms over 28 years.
Timing is unpredictable
Japan has maintained high debt ratios for decades. Scenarios that look certain can take far longer than expected — or may not happen at all.
