Yes—on the available snapshots, the estimated market capitalization of all cryptocurrencies was about 18% higher than the value of physical U.S. currency in circulation. CoinMarketCap showed roughly $2.83 trillion in global crypto market capitalization when retrieved on October 8, 2026; the Federal Reserve reported $2.3949 trillion in U.S. currency at December 31, 2025. The figures are from different dates, and they compare unlike measures: crypto market value versus the face value of notes and coins.
What the comparison says—and what it does not
Using those two figures, $2.83 trillion divided by $2.3949 trillion is approximately 1.18. That means the crypto market-cap estimate was about 18% greater than the cited year-end value of physical U.S. currency. The crypto number is a volatile observation, not a settled annual total, and no directly comparable same-timestamp pair is established here. CoinMarketCap’s live market overview and the Federal Reserve’s currency data should therefore be read as dated snapshots, not a timeless ranking.
This does not mean cryptocurrency is a more widely used currency, that crypto holders could collectively cash out at the quoted market value, or that crypto exceeds all U.S. money. It answers a narrower question: whether estimated global crypto market capitalization was greater than the face value of physical U.S. notes and coins in circulation on the cited observations.
What “U.S. dollars in circulation” means
The Federal Reserve’s currency measure is physical currency outside the Treasury, Federal Reserve Banks, and depository-institution vaults. Its denomination-value table includes Federal Reserve notes, U.S. notes, and currency no longer issued. It is not a count of every dollar in bank accounts or the broader U.S. money supply. The Fed’s H.6 release treats currency as one component of M1; M1 and M2 include additional monetary components.

U.S. notes and coins also circulate beyond U.S. borders. The U.S. Currency Education Program says as much as half of the value of U.S. currency may be circulating abroad, so the Federal Reserve figure is not limited to cash physically held inside the country.
Why crypto market capitalization is a different measure
CoinMarketCap describes total cryptocurrency market capitalization as the sum of the listed cryptocurrencies. For an individual asset, its valuation is based on circulating supply multiplied by a reference price. In other words, this is an estimate derived from market prices and supply figures—not a pile of cash set aside to pay holders. The CoinMarketCap market-capitalization explanation describes the calculation.
A quoted market price applies to trades at the margin. It does not show that every unit could be sold at that price if holders tried to sell simultaneously. The total also depends on circulating-supply estimates and which assets a data provider lists, so totals from different providers or methodologies may not match exactly.
The Federal Reserve’s cash figure changes over time
The Federal Reserve reported $2,322.9 billion in U.S. currency in circulation at December 31, 2024, and $2,394.9 billion at December 31, 2025. Those year-end figures come from the Fed’s currency and coin data. The increase illustrates why any comparison needs a date: the physical-currency measure changes, while crypto market capitalization can move sharply with asset prices and supply estimates.

CoinMarketCap’s historical snapshot for October 6, 2026, put Bitcoin’s market capitalization at about $1.719 trillion, Ethereum’s at about $329.4 billion, and Tether USDt’s at about $184.1 billion. These dated figures show that a large share of the overall crypto valuation was concentrated in a small number of assets; they are not a substitute for the separate October 8 total-market observation.

Physical currency is only one way to define U.S. money. M1 and M2 include broader monetary components, so comparing crypto capitalization with either aggregate would be a different calculation and require a specific measure and date. The figures above support a comparison with physical currency in circulation—not a claim that crypto is worth more than all U.S. dollars or the U.S. money supply.
