Nigeria Money Supply Jumps N7.5 Trillion in September to N146.6 Trillion
Nigeria money supply rose 5.4% in September to N146.6 trillion after a flat August, CBN data show. What drove the jump and what it could mean for inflation.
Nigeria money supply grew by about N7.51 trillion in a single month. Broad money (M3) reached N146.6 trillion in September 2026, up from N139.09 trillion in August, according to Central Bank of Nigeria (CBN) data reported by Nairametrics analyst Olalekan Adigun on 21 October.
That is a month-on-month rise of roughly 5.4%. It comes straight after a flat August, when M3 barely moved from July's N139.1 trillion. So the money stock did not drift higher over the quarter. It paused and then jumped.
Nigeria money supply in 2026: the monthly path
The CBN figures show broad money climbing for most of the year, with two sharp steps rather than a smooth line:
- January: N123.95 trillion
- April: N125.19 trillion
- May: N129.54 trillion
- June: N133.27 trillion
- July: N139.1 trillion
- August: N139.09 trillion
- September: N146.6 trillion
Between January and September, M3 rose by about N22.65 trillion, or roughly 18.3%. More than half of that increase came in two months: about N5.83 trillion between June and July, and N7.51 trillion between August and September.
Narrow money and cash moved far less
Narrow money (M1), which covers currency and demand deposits, rose from N43.11 trillion in August to N44.05 trillion in September. That is an increase of about N0.94 trillion, or 2.2%.
Currency outside banks edged up from N4.87 trillion to N4.92 trillion, a gain of about 1%. Cash in people's hands is therefore a small part of the story. Most of the September expansion sat in the wider M3 measure, which includes savings and time deposits and other less liquid holdings.
Why the jump matters
Money supply is one of the inputs economists watch when they try to judge where inflation is heading. More naira chasing the same goods can push prices up. But the link is loose and slow, and the Nairametrics report is careful on this point: the data alone do not show how much of the September increase turned into consumer spending or price pressure.
There are a few reasons to be cautious before reading the number as an inflation warning:
- Where the money sits. M1 grew at less than half the pace of M3. Growth concentrated in quasi-money such as time and savings deposits is less likely to hit shop prices quickly.
- Timing of policy. September followed a large rate cut by the CBN (see below). Some balance-sheet movement in banks after a policy change is normal.
- One month is noisy. August was flat. Averaging the two months gives growth of about 2.7% a month, which is still fast but less dramatic than the headline.
The policy backdrop: the biggest rate cut since 2006
At its 307th meeting, the CBN's Monetary Policy Committee cut the Monetary Policy Rate (MPR) by 350 basis points to 23%. Nairametrics describes it as the largest single cut since December 2006. The committee set the corridor around the MPR at +50 and -300 basis points.
It left the Cash Reserve Requirement unchanged at 45% for commercial banks and 16% for merchant banks, and kept the 75% requirement on non-TSA public-sector deposits. Those high reserve ratios are one of the tools the CBN uses to stop extra liquidity in banks from flowing straight into lending.
Before that cut, the MPR had been held at 26.50% at the 306th meeting in July 2026. In 2025, the rate was cut to 27% in September and held there in November.
How it fits with inflation and the naira
Headline inflation fell to 14.63% in September, its lowest reading since 2025, as we reported in our piece on why lower inflation has not yet eased living costs. A fast rise in money supply alongside a rate cut is the kind of mix that can slow or reverse that improvement if it persists.
On the currency side, the naira closed at N1,334.99 per dollar on 21 October, according to Nairametrics, slightly weaker than the N1,333 level it held a day earlier. A larger money stock does not move the exchange rate on its own, but it adds to the pressure if demand for dollars stays high.
What to watch next
For investors and businesses, the September figure is a signal to keep an eye on three things over the next two months:
- October M3 data. If broad money flattens again, September looks like a one-off adjustment after the rate cut. Another large rise would point to a looser trend.
- Private-sector credit. The CBN's credit figures will show whether banks are lending more after the cut, or holding the extra liquidity.
- October inflation. The next consumer price release from the National Bureau of Statistics will show whether the decline in inflation continues.
For now, the data say Nigeria's money stock is about 18% larger than it was in January, and that the central bank has chosen to ease policy anyway. How much of that money reaches prices is the question the next few releases will answer.
