Nigeria's Money Supply Surges to N138.78 Trillion in July, Defying Central Bank Tightening

Broad money supply expanded 16 percent year-on-year to N138.78 trillion in July 2026, contradicting the Central Bank of Nigeria's restrictive monetary stance. The expansion signals persistent liquidity pressures even as policy rates remain elevated, complicating inflation control efforts.

Nigeria's money supply ballooned to N138.78 trillion in July 2026, up sharply from N119.89 trillion a year earlier, according to latest monetary data. The 16 percent year-on-year expansion underscores stubborn liquidity growth that persists despite the Central Bank of Nigeria's aggressive interest rate hikes and open market operations designed to drain excess cash from the financial system.

The CBN has kept its policy rate at elevated levels throughout 2026, pushing borrowing costs higher across banks and the broader economy. Yet the continued expansion of broad money supply, commonly known as M3, suggests commercial banks continue lending actively while deposit growth remains robust. Economists warn this dynamic creates a dual challenge for monetary authorities seeking to control inflation while managing liquidity conditions.

The naira has borne much of the strain from excess liquidity. A money supply growing faster than economic output typically weakens currency value as the supply of naira increases relative to demand. The naira has depreciated consistently against the dollar throughout 2026, trading above 1,500 per dollar in recent months. A weaker currency makes imports more expensive, compounding inflationary pressures on goods ranging from fuel to food items. Nigerian consumers have felt the impact through higher prices at markets and filling stations across the country.

Business operators face mounting challenges from this liquidity expansion paired with high interest rates. Manufacturing firms and traders cite soaring borrowing costs, which squeeze profit margins even as inflation erodes purchasing power. A trader in Lagos' Lekki market noted that credit conditions have become prohibitively expensive, forcing many small businesses to operate on tight cash positions or seek informal financing at even higher rates. Real sector growth has slowed as a result, with the manufacturing and agricultural sectors reporting reduced investment activity.

The persistence of money supply expansion despite CBN tightening reflects structural factors in Nigeria's financial system. Government spending remains elevated as fiscal operations pump naira into the economy through wages, contracts, and transfers. Banks, flush with deposits from both government and private sources, continue extending credit despite higher policy rates. Open market operations by the CBN help drain liquidity temporarily but cannot fully offset the underlying growth drivers.

Analysts expect the CBN to maintain its hawkish stance in coming months, possibly raising rates further to combat inflation. If policymakers prove unable to bring money supply growth closer to nominal GDP growth rates, inflation could remain sticky above the bank's medium-term target range. This scenario poses risks for savers watching real returns on fixed income investments diminish, while debtors benefit temporarily from negative real interest rates before conditions tighten further.

The contradiction between declining money supply in real economic activity and rising nominal money supply highlights the challenge facing Nigeria's monetary managers. They must navigate between controlling inflation through rate hikes while avoiding damage to financial stability and economic growth. Success requires complementary fiscal discipline and structural reforms to boost productivity, but both remain elusive in the current environment.
