There is no single number, and anyone giving you one has quietly picked a definition without telling you.

“Money” means at least four different things depending on who is counting: physical cash, cash plus instantly spendable deposits, those plus savings, or everything anyone owns.

Each answer is larger than the last, by a lot. Here is what each one includes, and the one figure in this article we verified ourselves: all cryptocurrency together was worth $2.28 trillion on 6 August 2026.

The four measures, smallest to largest

1. Physical currency

Notes and coins in existence. The smallest measure by a wide margin, and the one most people picture when they hear the question.

Most money has not been physical for a long time.

2. Narrow money

Physical currency plus deposits you can spend immediately — current accounts, and the balance in your banking app.

Central banks publish this as M1 or an equivalent.

3. Broad money

Narrow money plus savings accounts, time deposits and near-equivalents. Published as M2 or M3 depending on the country.

This is the measure most “money in the world” figures are quoting, usually by adding up national series and converting to dollars. Sources disagree by tens of trillions because they include different countries and different instruments.

4. Total wealth

Everything owned: property, equities, bonds, businesses, commodities. Far larger than any money measure, and not money in any useful sense — you cannot spend a building.

Why nobody can give you a precise total

  • No single authority collects it. Each central bank publishes its own country, on its own definition and schedule.
  • Definitions genuinely differ. What counts as broad money in one jurisdiction is excluded in another.
  • Exchange rates move the answer. A dollar total for a mostly non-dollar world changes when currencies move, with nothing real having changed.
  • Some of it is deliberately unmeasured. Cash economies do not report.

A number quoted to the nearest billion is a sign the author did not understand the question.

Where crypto actually sits

Checked 6 August 2026 via CoinGecko:

  • Total crypto market capitalisation: $2.28 trillion
  • 24-hour trading volume: $56.0 billion
  • Bitcoin’s share: 56.66%
  • Ethereum’s share: 10.06%
  • Assets tracked: 18,154

Against global broad money — measured in the hundreds of trillions of dollars — all of crypto is a rounding error in the low single digits of a percent.

The comparison that gets misused

This is the part that matters, and it is where most “crypto vs the money supply” posts go wrong.

Market capitalisation is not money that exists inside crypto. It is the last traded price multiplied by supply.

If the final trade of the day values a token at $10 and there are a billion of them, the market cap reads $10 billion — regardless of whether $10 billion ever went in. The actual money that entered is a much smaller and largely unknowable number.

So “crypto is 1% of global money” compares a real stock of money with a valuation. They are not the same kind of quantity. Market cap explained takes this apart properly.

The same trap in the other direction

“If crypto captured 1% of global wealth it would be worth X” runs the same error backwards, and assumes buying pressure translates into market cap one-for-one. It does not.

How to sanity-check any figure you see

  • Ask which measure it uses. If the article does not say, it does not know.
  • Check whether it is money or wealth. They differ by an order of magnitude.
  • Look for a date. These series move continuously.
  • Distrust precision. Orders of magnitude are honest here; exact totals are not.

What to do next

If you are using this comparison to size a position, drop the global-money framing entirely and look at the one number that is measurable: 24-hour volume. Whether you can get out at the quoted price depends on that, not on how crypto compares to the world’s savings accounts.

Our market screener shows volume next to market cap on every asset for exactly that reason.

Educational content only, not financial advice. Crypto figures are a snapshot taken 6 August 2026 from CoinGecko. Global money supply is described in orders of magnitude deliberately: no single authority publishes a world total, and estimates vary by definition and source. Disclaimer
