Nigeria's money supply hit a record ₦129.21 trillion in May 2026 — but the rise came from foreign inflows, not bank lending

Nigeria's banking system held more money than ever in May 2026. Broad money supply (M3) — the widest official measure of naira and foreign-currency deposits circulating in the economy — rose to ₦129.21 trillion, up from ₦124.99 trillion in April, according to the Central Bank of Nigeria's money and credit data reported in late June.

That is an increase of ₦4.22 trillion, or 3.38%, in a single month, and a fresh record high. Year on year, M3 is up 8.40% from ₦119.20 trillion in May 2025 — a rise of about ₦10 trillion over twelve months.

Where the new money came from matters more than the headline

A bigger money supply is not automatically inflationary. What matters is why it grew. The CBN splits the system's assets into two buckets, and in May the split was lopsided.

Net foreign assets (NFA) — the foreign-currency claims of the central bank and commercial banks, net of foreign liabilities — jumped ₦2.94 trillion, or 12.23%, to ₦26.95 trillion from ₦24.01 trillion in April. That single line accounted for roughly 70% of the entire monthly increase in money supply.

Net domestic assets (NDA) — which capture bank credit to the government and to the private sector — grew far more slowly: ₦1.29 trillion, or 1.28%, to ₦102.26 trillion from ₦100.97 trillion. In other words, most of May's extra liquidity was imported through the foreign-exchange door, not created by a surge in domestic bank lending.

Oil money, not a credit boom

The foreign-asset surge lines up with the rest of Nigeria's recent macro picture. Crude output recovered above the country's OPEC quota in May, oil prices were firm during a period of Middle East tension, and external reserves climbed to a 17-year high near $51 billion. Those dollar inflows show up in the banking system as higher net foreign assets — and therefore as a bigger money supply — even when domestic credit is subdued.

The flip side is the modest growth in net domestic assets. With the CBN's policy rate held at 26.5%, working capital and term loans remain expensive, so many firms have been borrowing cautiously. A liquidity build-up driven by reserves rather than aggressive lending is generally less inflationary than one fuelled by a domestic credit boom, because it does not directly pump fresh naira demand into goods and services the way a lending spree would.

The CBN's tightrope

Rising money supply still complicates the central bank's job. The CBN is trying to drain naira liquidity to bring down inflation, which printed 15.93% in May. When deposits keep swelling, the bank has to work harder — through cash-reserve requirements and open-market operations — to mop up the excess and keep its tightening credible.

There is a reassuring detail in the numbers, though. Within M3, quasi-money (savings and time deposits) rose to ₦84.58 trillion from ₦81.22 trillion, meaning a large share of the growth sat in interest-bearing accounts rather than instantly-spendable cash — money that is parked, not chasing prices today.

It is also worth keeping the growth rate in perspective. M3 expanded 8.40% year on year, while nominal GDP grew far faster — about 17.8% over its latest comparison period. Broadly, money supply is rising more slowly than the naira value of national output, so the economy is not being flooded with liquidity relative to its size — a different picture from the rapid money-to-GDP expansion of earlier years.

Why this shows up in everyday prices

For households and businesses, the money-supply report is a lead indicator that connects to the dated prices Opaindex tracks. Three threads run through it:

• The naira. Stronger net foreign assets and reserves are the same forces that have steadied the naira and the FX market. A better-supplied dollar market eases the imported-cost pressure that feeds into fuel and food.
• Inflation. As long as the extra liquidity is reserves-led and parked in savings, it is less likely to reignite price pressure on staples such as local rice. A swing toward fast-growing domestic credit would be the warning sign to watch.
• Borrowing costs. Subdued domestic credit at a 26.5% rate means firms financing petrol- and diesel-powered operations are still paying up for working capital, a cost that ultimately shows up at the pump and on the shelf.

The practical read

May's record money supply is best read as a sign of strength in Nigeria's external accounts rather than a fresh inflation alarm. The system is fuller, but the fuel was foreign inflows and parked savings, not a lending boom — and total money is still growing more slowly than nominal output. The number to watch in the months ahead is net domestic assets: if bank credit to the private sector starts accelerating sharply, that would mark a more inflationary phase of liquidity growth, and a tougher one for the CBN's 26.5% stance to hold the line on.
