Hyperinflation Examples
By November 1923, one US dollar bought 4,210,500,000,000 Weimar marks. German children played with the bills as toy blocks — the currency had gone that worthless. The photo of them doing it is the highest-reach hyperinflation post in our community research: 65,034 upvotes on r/Damnthatsinteresting (2024-12-22). This hub collects ten hyperinflation examples and answers a narrower question: how fast does money have to grow before a currency collapse counts as hyperinflation, rather than just fast money printing?
Hyperinflation, by the standard economists use, means a monthly inflation rate above 50% — the threshold Phillip Cagan set in 1956. Sustained for a full year, that rate compounds to roughly 12,875%. It is a price-inflation threshold and not a money-supply one, which is why this hub keeps the two claims apart.
Specs — the Cagan threshold, against our fastest data
| Cagan definition (50% per month) | Prices +50% in one month |
| The same rate compounded over 12 months | ≈12,875% |
| Fastest money growth in our data | Zimbabwe, 338.2% a year, annualised over the 47 months since its 2022-05 redenomination (2026-04) |
| Fastest over a full ten years | South Sudan, 69.6% a year, 10-year CAGR (2026-06) |
| Argentina, the live case in the FAQ below | 62.8% a year, 10-year CAGR; 40.2% in the year to 2026-01 |
| Our own episode series, start to today | Argentina 1989, Brazil 1990, Peru 1990 — all from 1960 |
| Episodes we hold no series for | Weimar 1923, Hungary 1946, Zimbabwe 2008, Venezuela 2016–2019, Yugoslavia 1994, Lebanon 2020 |
Fast money growth isn’t the same thing
Zimbabwe’s broad money is the fastest-growing series we hold: 338.2% a year, annualised over the 47 months since its May 2022 redenomination (2026-04). Its money supply rose 326-fold across those 47 months. One Cagan year is a 129.7-fold rise in twelve. So Zimbabwe does clear a Cagan year’s worth of money growth. It just takes 3.3 years instead of one.
Rates measured over different windows are not comparable, so the ten-year ranking is a separate table. South Sudan leads it at 69.6% a year (2026-06), with Argentina at 62.8% on the same 10-year basis (2026-01). South Sudan would need about 9.2 straight years at its rate to produce what one Cagan year produces in twelve months.
Zimbabwe’s broad money did clear 50% in a single month, four times since the break: +101.2% in May 2023, +97.2% in June 2023, +54.6% in January 2024, +63.7% in April 2024. None of those is a Cagan month. Cagan counts prices, and we hold no price series for any of these countries. So “is Argentina in hyperinflation now” has one honest answer here: not by money supply, because 62.8% a year is 4.1% a month. The price side isn’t ours to check.
Which of these ten hyperinflation examples we can actually chart
Three of the ten pages in this hub carry our own money-supply series end to end — Argentina (1989), Brazil (1990) and Peru (1990), each charted from 1960. The other seven don’t carry a new series of their own. Weimar Republic 1923 and the Hungary 1946 pengő both predate our IMF data. Zimbabwe’s own series starts at dollarization, December 2009, after the 2008 peak and its $100 trillion note. Venezuela (2016–2019), Yugoslavia (1994, several currency redenominations that year alone) and Lebanon (2020) fall in a gap we haven’t backfilled. The tenth page, our companion answer page, synthesizes the three series we hold rather than adding an eleventh. We say which is which on every page rather than letting all ten look equally documented.
Worth stating plainly, since it’s the correction most lists get wrong: the worst hyperinflation on record isn’t Zimbabwe’s. Hungary’s 1945-46 pengő holds that position — prices reportedly doubled roughly every 15 hours at the peak, a rate none of the other eight episodes reach.
How it usually ends
Every ending we can chart end-to-end starts the same way: a government loses the ability to finance its deficit by printing money. Zimbabwe did it by dollarizing (2009). Argentina did it with a currency board (1991). Brazil and Peru did it with a new currency backed by fiscal reform (1994 and 1990-91). None of the four stayed ended by default — at its rate since the 2022 redenomination, Zimbabwe’s money supply doubles every 5.6 months.

FAQ
What causes hyperinflation?
Historically, a government financing its deficit by having the central bank create money, at a scale large enough to push the monthly inflation rate past 50%. Fast money-supply growth alone isn’t sufficient. The fastest series we hold is Zimbabwe’s, at 338.2% a year since its 2022 redenomination (2026-04), and it has cleared 50% in four separate months — none of them a Cagan month, because Cagan counts prices rather than money.
Is Argentina in hyperinflation right now?
Not by money supply. Argentina’s broad money is growing 62.8% a year on a 10-year average, and 40.2% over the most recent 12 months (2026-01). That works out to 4.1% a month against Cagan’s 50%. We don’t hold Argentina’s price-inflation series, so that side of the question isn’t ours to answer from this dataset.
