The Central Bank of Nigeria (CBN) has reduced the country's benchmark interest rate from 26.5 per cent to 23 per cent, marking a 3.5 percentage-point adjustment that has renewed attention on borrowing costs for businesses and households.

The decision was announced by CBN Governor Olayemi Cardoso on Tuesday, September 22, 2026, following the conclusion of the Monetary Policy Committee's 307th meeting in Abuja.

The new Monetary Policy Rate (MPR) is 23 per cent, down from 26.5 per cent, but the CBN has described the adjustment as an operational reset rather than a conventional change in its monetary policy stance.

The committee explained that the previous benchmark had become increasingly disconnected from interest rates operating in the financial market, weakening its effectiveness as a monetary policy signal.

According to the CBN, the adjustment is intended to align the benchmark more closely with market conditions and improve the transmission of monetary policy decisions through the banking system.

The committee also recalibrated the standing facilities corridor around the MPR to 50 basis points above and 300 basis points below the new benchmark.

Before the latest decision, the corridor stood at 50 basis points above and 450 basis points below the previous rate.

The CBN retained the Cash Reserve Requirement for deposit money banks at 45 per cent and that of merchant banks at 16 per cent.

The 75 per cent requirement applicable to public-sector deposits held outside the Treasury Single Account was also retained.

Cardoso said the committee's decision was intended to strengthen the effectiveness of monetary policy and restore the benchmark rate as the principal signal for financial market operations.

The adjustment follows a period in which the central bank maintained its benchmark rate at 26.5 per cent during its May and July monetary policy meetings.

The September decision brings the rate to its lowest level since February 2024.

However, a lower benchmark rate does not automatically mean that existing bank loans will immediately become cheaper.

The interest charged on individual loans depends on several factors, including the bank's funding costs, the borrower's credit profile, loan conditions and whether the agreement provides for a fixed or variable interest rate.

For borrowers with fixed-rate loans, the CBN's decision does not automatically change the rate agreed upon with their banks.

Customers with variable-rate facilities may see changes depending on the terms of their loan agreements and how their banks adjust lending rates.

The Centre for the Promotion of Private Enterprise (CPPE) has said the lower benchmark could help reduce financing pressures on businesses and improve investment conditions.

In a policy brief issued after the announcement, the organisation argued that high borrowing costs had placed pressure on businesses, particularly those dependent on bank financing.

However, any improvement in actual lending conditions will depend on how banks respond to the revised monetary policy framework.

The CBN's decision also comes amid a moderation in Nigeria's headline inflation rate.

According to figures referenced in the monetary policy announcement, headline inflation eased to 15.39 per cent in August 2026 from 15.43 per cent in July.

The committee said it would continue monitoring economic developments and the effectiveness of the revised policy framework in guiding future decisions.

For Nigerian borrowers, the immediate development is a reduction in the official benchmark rate.

Whether that translates into lower interest charges on business loans, mortgages and other credit facilities will depend on subsequent lending decisions by financial institutions and the terms of individual loan agreements.
