US vs China Money Supply: The $11.96 Trillion Gap
China’s broad money supply is $42.64 trillion. The date is 2024, from World Bank annual data. The United States’ is $30.68 trillion, as of December 2025, from the IMF’s quarterly harmonised broad-money series. That’s an $11.96 trillion gap. The broad money ratio here is 1.39 — not the round 2x number “X times larger” headlines imply. The two figures are also a year apart. China’s is the older one and grows faster (see below), so a matched-date comparison would widen this gap, not narrow it. Broad money counts currency, checking and savings balances, and short-term bank deposits — not the monetary base (currency plus bank reserves), which is smaller for both countries.

This isn’t a wealth ranking
Google’s “people also ask” panel for this query drifts toward “who is economically stronger, the US or China.” That’s the conflation this comparison keeps running into. A 2024-12-13 r/economy post, titled “M2 money supply. USA = $21 trillion. China = $42 trillion” (u/wakeup2019), drew 8 replies. One reply asked the real question: “So, China is double the US by 23T? On serious note, what is M.2 used for?” (u/kidfromtheast). It isn’t a wealth question. u/RobThorpe answered it plainly on r/AskEconomics: “It’s important to understand that M2 is not a measure of wealth. It’s a measure of money supply. A person can be wealthy without having their wealth in a liquid form.”
The $21T in that post is the Fed’s headline M2 (FRED M2SL) — a different, narrower series from the $30.68T IMF harmonised figure this page uses for the US; see methodology. Either way, China’s $42.64T sitting above the US figure describes how each economy holds its liquid bank money — not which one is richer.
The standard rebuttal, pre-answered
Here’s the mechanism, so it doesn’t need re-explaining. US household wealth sits mostly outside M2. Replying in the same thread, u/High_Contact_ (10 upvotes, 2024-12-13) put numbers on it: a $55 trillion US stock market (about 5x China’s), a $53 trillion bond market (nearly double China’s), $30 trillion in mutual funds and ETFs (about 6x China’s), and $150 trillion in US household net worth — almost double China’s. M2 alone can’t see any of it.
China’s system runs the other way. The same commenter, earlier in the thread: “China’s financial system is dominated by state owned banks, and credit flows primarily through them rather than capital markets like in the U.S.” A high household savings rate, fewer investment options, and strict capital controls keep Chinese savings inside bank deposits — the exact slice M2 measures. Same underlying economic activity. Structurally different places for it to land.
Growth: which one is diluting faster
China’s broad money grew 6.8% year-on-year as of 2024. The US grew 6.0% as of December 2025 — close in size but a year apart. Averaged over the past decade (10-year CAGR, each ending on its own latest date), the gap widens. China’s is 9.6% a year through 2024, the US’s 6.6% through December 2025. That puts China’s doubling time at 7.6 years, against 10.9 for the US. Name the metric and the date together — a 10-year average and the past year answer different questions, and mixing them is this comparison’s most common error.
The chart above indexes both curves to 100 at each country’s own start year, so the growth-rate differential is visible without currency conversion. YoY, CAGR and doubling time are each a ratio of a currency to itself.
Per person, the gap reverses
China’s 2024 population was 1.41 billion (1,408,975,000, World Bank SP.POP.TOTL); the US’s was 340 million (340,003,797, SP.POP.TOTL). Divide each country’s broad money by its population and the headline flips. China works out to about $30,264 per person, the US to about $90,241 — 2.98 times China’s figure, roughly the mirror image of the 1.39 national ratio. The US side carries the same vintage mismatch: broad money from December 2025, divided by population from 2024. A country can hold a smaller total and a larger per-person figure at once. Both numbers are correct — they just answer different questions.
What the top search results miss
Type “us vs china money supply” into Google (checked 2026-08-14) and five of the top 12 organic results already pair both countries — the r/economy thread above (#2), an x.com post (#3), streetstats.finance (#6), voronoiapp (#10) and a Wikimedia comparison image (#11). TradingView is one of the eight data sites in our competitor set. Its result here is a China-only page at #12, outside the top ten. None of those five pairs both figures, their dates, and the wealth-ranking correction — that combination is what’s missing. You’re still expected to open two tabs and do the subtraction yourself.
China’s money supply and the United States’ money supply each carry the full native-currency history behind these numbers, ranked against 185 economies worldwide on money supply by country. Full mechanics on the methodology page.
FAQ
Is comparing M2 across countries even valid?
Only with two caveats. This page’s US figure is the IMF’s quarterly harmonised broad-money series — not the Fed’s monthly M2. China’s figure here is annual World Bank data, and every country defines its own aggregate. YoY, CAGR and doubling time compare validly with no conversion needed — each is a ratio of a currency to itself. Level comparisons in USD are valid too, but there’s a PPP caveat. Our figures use market exchange rates, not purchasing-power-parity ones, so they don’t adjust for what a dollar buys inside each country.
When did China’s M2 overtake the US’s?
We can’t give a verified date. Our USD conversion is a single-year snapshot for each country’s latest observation, not a matched historical series in one currency across decades — that’s a gap in our coverage, not a design choice.
Does a bigger money supply mean China is wealthier than the US?
No. Broad money is the liquid, bank-held slice of an economy. It excludes equities, bonds, real estate and retirement assets — which is why the US’s $30.68T sits below China’s $42.64T without the US being the poorer economy.
How does the per-capita money supply compare?
It reverses the headline: about $30,264 per person in China against about $90,241 per person in the US (World Bank SP.POP.TOTL, 2024). That’s roughly a 3x gap running the opposite direction from the national totals.
