About M2 Index

M2 Index publishes broad money — M2, or the local equivalent — for 185 tracked countries and currency unions, 165 with their own reported series (as of 2026-06). Coverage runs back to 1960 for the deepest rows, in domestic currency and USD, free with no email gate.

What we publish

As of 2026-06 we track 185 countries and currency unions. 165 carry their own reported series. The other 20 are euro-area members that share the Euro Area series, because they don’t issue a currency of their own. Frequency is monthly where the IMF’s release schedule allows it, and annual where we fall back to World Bank data. The deepest rows reach back to 1960. Every figure ships in its home currency and in USD. The full dataset downloads free at the data page, no email required.

Why this site exists

Two kinds of page already cover this data. Neither is this one. The IMF, the World Bank and national central banks publish correct numbers and explain almost nothing. You need to know what a series code means before the page is any use. Community threads do explain what a growth rate means, on numbers nobody sourced or dated. We sit in the gap: primary-source figures, dated and identified, next to the reasoning to use them. Where a rival page is wrong or stale, we say so with the date we checked it. That goes on the ranking page making the claim, not here.

What this site will not do

M2 Index is a data reference, not an advisor. No investment recommendations, no price predictions — a growth rate is not a forecast. Nothing here sits behind a paywall or an email gate. And we don’t invent numbers to fill a gap. Where a figure is missing — an FX rate that doesn’t exist, a central bank API that times out — the page says missing, and says why.

Why you don’t have to trust us

A name on a page is worth little on its own. So we built this site to be checked instead. Every figure carries its source, its series code and the date we observed it. Follow those three and you reach the IMF, World Bank or ECB series we read it from. Then you can see for yourself whether we copied it right.

What we can hand you outright depends on the licence. World Bank data is CC BY 4.0, so the seven backfilled series ship as raw numbers, attributed. IMF and ECB terms are stricter. The other 178 rows ship what we calculate on top instead: YoY growth, 10-year CAGR, doubling time and the USD conversion, each labelled as ours, beside a link to the primary series. The full build: methodology.

Corrections, published in public

Every figure carries the date we observed it. Rows older than 24 months carry a visible staleness badge, rather than pretending to be current. Refresh timing follows the source, not one calendar for the whole site: IMF rows on the IMF’s monthly schedule, World Bank backfill rows once a year, the euro area monthly from the ECB.

When we get something wrong, we log it at the corrections page, in public. We don’t edit it away quietly. Tell us if a number disagrees with its primary source. That’s a bug we want reported.

Who’s behind M2 Index

M2 Index is built and maintained by the M2 Index Data Team. We are a small data project, not a newsroom and not a financial-advice desk. We are not naming one economist or a review board today, because there isn’t one yet. Inventing one would be worse than saying so. If that changes, this page will say who, and when.
