Ikechukwu Eze, who operates a cold storage facility in Onitsha, illustrates the severe challenges Nigerian businesses face. In November 2023, he borrowed N8 million from his bank at 32% per annum. A four-day power outage, which began fourteen days later, led to 40 percent of his stock becoming unsalvageable, forcing him to sell the remainder below cost and default on his loan repayments.

Two years later, despite the Monetary Policy Committee (MPC) having initially retained the MPR at 27.50% for three consecutive meetings, and later reducing it to 26.50% in February 2026, Ikechukwu's credit bureau record remained a barrier to new financing. This occurred even as Nigeria's headline inflation dropped to 15.91% by June 2026, from a December 2024 peak of 34.80%, benefiting partly from CPI rebasing in 2025.

The tightening cycle, which commenced in 2022 and intensified in 2024 under Governor Olayemi Cardoso, saw the MPR increase by a cumulative 875 basis points across six consecutive MPC meetings, from 18.75% in January 2024 to 27.50% by November 2024. This was primarily aimed at curbing inflation driven by monetary financing, fuel subsidy removal, and exchange rate depreciation.

However, the policy disproportionately affected productive businesses rather than the targeted FX arbitrageurs. Commercial banks, facing a choice between risky SME loans and risk-free 364-day Treasury bills with a stop rate of 26.10% during the peak tightening period, opted for government securities.

This crowding-out mechanism led banks to accumulate N5.05 trillion in government securities, reducing their appetite for productive lending. As of July 2026, the effective annual yield on the 364-day bill stands between 20% and 21%, while commercial bank SME lending rates range from 28% to 46%, perpetuating the structural preference for government paper.

Nigeria's domestic credit to the private sector remains critically low at approximately 13% of GDP, significantly trailing economies like Kenya (32%) and South Africa (over 70%). This indicates a deep-seated market failure in credit allocation.

A significant portion of Nigeria's inflation was supply-driven, stemming from fuel subsidy removal, insecurity affecting food production, rising transport costs, and Naira depreciation. Raising interest rates, while effective against demand-pull inflation, does not address these fundamental supply-side issues, instead compressing demand from businesses already struggling with these shocks.

The distributional consequences of tight monetary policy are also pronounced. High interest rates benefit wealthy depositors, pension funds, and banks earning substantial profits from government securities. Conversely, they penalize SMEs that rely on commercial banks for capital and cannot access capital markets.

The informal economy, comprising approximately 40 million MSMEs that account for over 50% of GDP and 92.3% of employment (SMEDAN), has largely disengaged from formal lending. PwC's MSME Survey 2024 revealed that only about 4% of MSMEs access formal bank credit. The Moniepoint Informal Economy Report 2025 indicated that 51% of informal businesses had never taken a formal loan and had no intention to, up from 30% in the previous year.

Nigeria faces an MSME financing gap exceeding $200 billion, a scale that cannot be resolved by MPC decisions alone without complementary structural reforms. The CBN's 26.50% MPR is merely a starting point, not a solution to the persistent crowding-out effect caused by the combination of an elevated policy rate and a substantial fiscal deficit.

The 2026 budget carries an estimated deficit of approximately N20 trillion. This scale of government borrowing ensures that even a declining MPR does not free commercial banks from the allure of sovereign paper, maintaining a crowding-out premium on private sector borrowing costs.

Three key interventions are crucial for progress. First, meaningful fiscal consolidation through non-oil revenue mobilization and reduction of non-productive recurrent expenditure is needed. Second, a Development Finance Institution (DFI) capitalized at a scale proportionate to the $200 billion credit gap is essential, as existing institutions like the Bank of Industry, Development Bank of Nigeria, and NIRSAL Microfinance Bank are insufficiently funded.

Third, the operationalization of the movable collateral registry under the Secured Transactions Act would allow businesses to borrow against receivables, inventory, and equipment, rather than requiring real property that most small businesses do not formally own. This would significantly expand productive credit access.

Scenario projections suggest that continued MPR reduction toward 18% by 2028, coupled with meaningful fiscal consolidation and a scaled SME credit facility, could increase the share of Nigerian MSMEs with formal credit access from 4% today to approximately 20% by 2030. The status quo trajectory, however, projects only a 5% access rate by the same date, a mere 1 percentage point improvement over four years, while the absolute credit gap continues to widen.

Ikechukwu Eze's experience underscores that the interaction of a power cut and a 32% interest rate turned a Nigerian operational problem into a terminal one for his business, highlighting the urgent need for comprehensive reforms beyond just interest rate adjustments.
