Money Supply (M1/M2/M3)
Different measures of how much money is circulating in the economy, ranging from the most instantly spendable to the broadest definition that includes fixed deposits.
Explain it like I'm 10
Think about your own money in tiers of how quickly you could actually spend it. The cash in your wallet and whatever's sitting in your savings account you could spend right now — that's the narrowest tier. Add in money in a post office savings account, still fairly liquid — that's a slightly broader tier. Now add every fixed deposit you own, money that's technically yours but would take a bit of notice or a small penalty to access — that's the broadest tier. Economists track the entire economy's money the same way, in nested tiers labelled M1 (narrowest) through M3 (broadest, and the one most commonly watched).
The formula
M1 = Currency with the public + Demand deposits with banks M2 = M1 + Savings deposits with Post Office savings banks M3 = M1 + Time deposits with banks (the headline, most-watched measure) M3 outstanding stock: FY24 ≈ ₹223 lakh crore FY25 ≈ ₹269 lakh crore (+22% — a sharp acceleration) FY26 ≈ ₹320 lakh crore (continued double-digit growth)
Historical data
The stock keeps rising every year almost by definition in a growing, financialising economy — what matters more to economists is the growth rate, which accelerated sharply to roughly 22% in FY25 before moderating to the 10-11% range through late 2025 and into 2026.
Who calculates it
The RBI compiles and publishes M1, M2 and M3 data through its Weekly Statistical Supplement and Handbook of Statistics on the Indian Economy.
Where this number can mislead you
- ⚠Money supply growth doesn't map one-to-one with inflation in the short run — M3 can grow because more people are opening bank accounts and formalising savings (financial deepening), not only because monetary policy has turned loose.
- ⚠India discontinued regular official computation of M2 some years ago in favour of M1 and M3 as the primary published aggregates, which makes cross-country comparisons involving India's M2 figure unreliable or outdated.
- ⚠The relationship between money supply growth and nominal GDP growth (captured by a concept called the "velocity of money") isn't stable over time, so M3 growth alone is an imperfect standalone predictor of where GDP or inflation is headed.
- ⚠Rapid M3 growth running well ahead of real GDP growth is one classic early-warning signal economists watch for building inflationary pressure, but it is only one signal among several, not a standalone verdict on its own.
Reality check
M3 broad money supply grew roughly 22% in FY25, jumping from about ₹223 lakh crore to nearly ₹269 lakh crore in a single year, before growth moderated to the 10-11% range through late 2025 as the RBI's own liquidity and rate actions began to temper the pace — a reminder that the growth rate of money supply, not just its ever-rising absolute level, is the number economists actually watch.
