The same years of inflation, lived in 21 different currencies
“Inflation” sounds like one thing that happens to everybody. Put the same 35 years next to each other in 21 currencies and it stops looking like one thing at all: the range is not a few percentage points, it is several orders of magnitude.

The spread
Taking each country's own consumer price index and asking what 1990 money became by 2025: prices multiplied by ×1.2 in Japan — a total increase of about 25% across 35 years — and by ×234,414 in Brazil. That is a factor of roughly 187,727 between the calmest and the fastest case, for the same stretch of history. Spain, in the middle of our 21 countries, came in at ×2.6.
Sit with the low end for a moment, because it is the stranger one. A currency where prices only rose 25% in 35 years means a saver could keep money in cash for a generation and lose surprisingly little purchasing power — the exact opposite of the intuition most of the world has about money.
What a huge multiple does not mean
A multiple in the thousands is the single most misread number in this dataset, so it is worth being precise. It says that the price index rose by that factor: a basket costing 1 unit in 1990 costs that many units at the end. It does not mean people are that many times poorer, because wages moved too — often nearly as fast, sometimes not.
It is also not the same thing as a currency reform. 3 of these 21 countries (Brazil, Türkiye, Poland) removed zeros from their banknotes at some point in this period. A price index passes straight through such a reform — it keeps measuring prices continuously — but the printed money did not: old and new notes are different units. So when you see an index multiple in the tens of thousands, do not multiply today's banknote by it and expect a meaningful answer. That is why our tools show the index honestly and warn where a currency was redenominated.
Why the gap exists at all
The countries at the calm end share unglamorous things: an independent central bank with an explicit target, debt mostly issued in its own currency, and no long stretch of financing government spending by printing money. The fast end usually reflects some combination of the opposite, often with a currency crisis in the middle of the series that shows up as a near-vertical segment in the chart. None of this is a moral ranking of nations — it is monetary plumbing, and plumbing can be repaired: several countries in the fast group have had long calm periods since.
The practical lesson is uncomfortable but simple: how much your savings can safely sit in cash is not a personal-finance preference, it is a function of the currency you happen to be paid in. Advice written for a ×1.2 country can be actively harmful in a ×234,414 one.
See it in your own currency
Numbers like these only land when they are yours. The inflation time machine takes an amount, a year and a country, and shows what that money is worth now in your own currency, with the whole index curve behind it.
