How new CBN rate will shape savings, loans, and investments

The Central Bank of Nigeria (CBN) has reduced its benchmark interest rate, the Monetary Policy Rate (MPR), by 50 basis points to 27 per cent from 27.50 per cent. The decision, reached at the 302nd meeting of the Monetary Policy Committee (MPC) held on September 22 and 23, 2025, marks the first rate cut in five years and signals a policy shift aimed at stimulating economic activity.

Policy decisions and key adjustments

At the end of its two-day deliberation, the MPC voted unanimously to lower the MPR. It also reduced the Cash Reserve Requirement (CRR) for commercial banks to 45 per cent from 50 per cent, while retaining that of merchant banks at 16 per cent. In addition, a 75 per cent CRR was introduced on non-Treasury Single Account (TSA) public-sector deposits to manage excess liquidity from fiscal injections.

Olayemi Cardoso, the CBN governor, said the move was driven by “five consecutive months of disinflation, projections of further moderation in inflation through the rest of 2025, and the need to sustain recovery momentum in the economy.”

The Liquidity Ratio (LR) was left unchanged at 30 per cent, ensuring banks maintain adequate liquid assets to meet withdrawal demands. The symmetric corridor around the MPR was fixed at +250/-250 basis points, setting the Standing Lending Facility (SLF) rate at 29.5 per cent and the Standing Deposit Facility (SDF) rate at 24.5 per cent.

What the changes mean

Ayodeji Ebo, managing director and chief business officer at Optimus by Afrinvest, explained the implications of these decisions for the financial system. He said the MPR serves as the “benchmark interest rate at which the CBN lends to commercial banks and anchors all other rates in the economy.”

He noted that the CRR determines the portion of deposits banks must keep with the CBN. With the new 45 per cent CRR, “for every N1,000 deposited in the bank, N450 must be retained with the CBN, leaving only N550 available for lending.” The new 75 per cent CRR on non-TSA public-sector deposits means banks can deploy just N250 of every N1,000 received, limiting liquidity from government funds.

Impact on savers and borrowers

For savers, the reduction in MPR means lower returns on savings deposits. By regulation, banks must pay at least 30 per cent of the MPR on savings accounts, which now translates to a minimum of 8.1 per cent, down from 8.25 per cent. Savers may now seek higher yields through fixed deposits, money market funds, or fixed-income instruments.

Borrowers, on the other hand, could see gradual relief as loan rates adjust downward. Although the effect may take time due to tight liquidity, the reduction in MPR is expected to lower the cost of borrowing and ease debt service pressures.

Effect on investors and markets

Fixed-income investors will likely experience a further decline in yields on treasury bills and bonds, reducing the appeal of these instruments. Pension funds and institutional investors may diversify into equities, infrastructure funds, and other real assets.

The stock market could benefit from increased investor interest as lower fixed-income returns drive a shift towards equities. Non-financial companies may also gain from lower borrowing costs, improving their capacity to expand operations and raise capital.

Balancing growth and liquidity

The new measures aim to balance growth stimulation with monetary control. The reduction in SLF and SDF rates is designed to align interbank rates with the new MPR, while the high CRR on non-TSA deposits ensures banks do not rely excessively on government funds for liquidity.

While the policy stance is expected to support credit growth and investment over time, the tight liquidity conditions may limit the immediate impact. The coming months will show how effectively the rate cut transmits through the financial system to real sector activities.
