m1 money supply
M1 Money Supply is the cash, coins and money in current accounts that you can spend right now, without waiting for it to mature or convert.
In plain English
Here is the surprising part. The money sitting in your fixed deposit account at a Nigerian bank, the one earning you a tidy interest rate, does not count as part of M1. It exists, it is yours, it even shows up on your bank statement, but economists looking at M1 simply walk past it, because M1 only cares about money you can spend in the next five minutes, not money you have to wait to touch.
M1 is the narrowest, most liquid slice of a country's money supply. It includes the physical cash and coins moving around in people's pockets and market stalls, plus the balances sitting in current accounts and other accounts you can withdraw from on demand, using a card, a cheque or a bank transfer, without notice or penalty.
Think about a trader at Balogun market in Lagos. The ₦50,000 in her cash box and the ₦200,000 sitting in her current account, both ready to be spent the moment a customer or a supplier calls, are M1. But the ₦500,000 she locked away in a 90 day fixed deposit to earn better interest is not, because she cannot spend it today without breaking the agreement.
In the United Kingdom, the Bank of England tracks a similar measure, watching how much spendable cash and current account money is floating around, because it tells a story about how quickly people might start spending and how prices could react.
For someone in London sending money home to Lagos, the moment that transfer lands in a Nigerian current account, it joins M1 immediately. It is now spendable, countable, ready to buy rice, pay school fees or settle a generator repair, and the Central Bank of Nigeria notices that ripple when it studies the numbers.
If Adaeze has ₦30,000 cash in her purse and ₦120,000 in her GTBank current account, that ₦150,000 counts as M1. Her ₦1,000,000 fixed deposit earning 12% annual interest does not count, because she cannot spend it without breaking the term.
Questions people ask
Why does M1 Money Supply matter to ordinary people?
Because it hints at how much spending power is loose in the economy right now. When M1 grows fast, more money is chasing goods on the shelf, and that can push prices up, which affects everything from garri to school fees.
Is money in savings accounts part of M1?
Usually not in the strict sense, since M1 focuses on cash and current accounts you can access instantly. Savings accounts and fixed deposits sit in the wider M2 measure instead, because they take a little more effort or notice to withdraw.
Does mobile money and bank transfer balances count as M1?
Yes, if the money is sitting somewhere you can spend it immediately, such as a current account linked to a bank app or a mobile wallet, it counts as part of M1, since the test is how quickly it turns into a purchase.
