Bitcoin vs the world's
top 10 currencies.
"Bitcoin is a hedgehedgeAn investment made to offset potential losses in another position, like buying gold to protect against currency declines. against the dollar" undersells it. Priced in bitcoin, every national currency loses ground over time. The dollar, the euro, the yen, all of them. The dollar is the strongest horse in the glue factory.

Priced in bitcoin, all ten of the most-traded currencies, including the dollar, lost ground over the past decade, and inflation runs far higher outside the top ten, above 30% a year in Argentina and Turkey. This page argues bitcoin hedges all fiat, not just the dollar, at the cost of sharp short-term volatility.
Priced in bitcoin, every fiat currency falls
The chart shows one unit of each of the world's ten most-traded currencies, measured in bitcoin terms and indexed to 100 a decade ago. Doesn't matter which flag is on the note. Over a long horizon they all decay toward the floor. The only debate is speed.
The fiat side: debasement is universal, the rate is local
Forget bitcoin for a second. Look at what each currency does on its own. Below is the latest annual inflationinflationA general increase in prices over time, meaning each dollar buys less than it did before.Full definition for the top 10 most-traded currencies (BIS Triennial Survey ranking) plus a few harder-hit ones. "Low" inflation isn't zero. Two to three percent a year still halves your purchasing power in roughly 25 to 35 years. It's a slow leak, not no leak.
| # | Currency | Latest annual inflation | ~10yr purchasing power lost* |
|---|---|---|---|
| 1 | US dollar (USD) | 3.4% | ~28% |
| 2 | Euro (EUR) | 3.2% | ~25% |
| 3 | Japanese yen (JPY) | 1.9% | ~14% |
| 4 | British pound (GBP) | 3.1% | ~28% |
| 5 | Chinese yuan (CNY) | 0.8% | ~17% |
| 6 | Australian dollar (AUD) | 4.0% | ~29% |
| 7 | Canadian dollar (CAD) | 3.0% | ~25% |
| 8 | Swiss franc (CHF) | 0.8% | ~9% |
| 9 | Hong Kong dollar (HKD) | 1.7% | ~18% |
| 10 | Singapore dollar (SGD) | 2.3% | ~20% |

And it's far worse where most of the world lives
The top 10 are the strong currencies. Step outside them and the leak becomes a flood. These aren't fringe economies. Hundreds of millions of people earn and try to save in them:
| Currency | Recent annual inflation | Context |
|---|---|---|
| Argentine peso (ARS) | 32.4% (Apr 2026, INDEC) | Down from ~118% at end-2024. Decades of serial debasement. |
| Turkish lira (TRY) | 32.6% (May 2026, TÜIK) | Official rate; independent ENAG estimates run higher. Energy shock driving food and transport costs. |
| Nigerian naira (NGN) | 15.7% (Apr 2026, NBS) | Down from ~33% in 2024, but the naira has shed enormous value against the dollar this decade. |
For someone earning in pesos or lira, bitcoin is the first savings account in their life that the central bank can't quietly drain, not a speculative bet. That's the global story the "dollar hedge" framing misses entirely.
The honest part: bitcoin is volatile, and that's the price of admission
None of this means bitcoin only goes up. As of September 19, 2026, BTC is down roughly 30% from its level a year earlier (~$116K to ~$81K). Over any single year it can fall harder than any currency on this page. The case here is not "bitcoin beats fiat next quarter." It's that over a multi-year horizon, a fixed-supply asset has outrun every infinitely-printable one as a place to store work. You're trading short-term volatility for long-term protection from debasement. If you can't sit through the volatility, the math doesn't help you. If you can, time has done the rest, in every currency, not just the dollar.
Inflation figures are point-in-time anchors and change constantly; verify the current rate for your currency with its national statistics office. The bitcoin comparison uses a 10-year window because that horizon matches the thesis. Bitcoin's short-term price is volatile and frequently negative.
