Nigeria’s latest interest-rate cut has changed the dynamics of the West African investment landscape, with Ghana now offering a wider gap between its policy rate and inflation. The Central Bank of Nigeria (CBN) reduced its benchmark Monetary Policy Rate (MPR) by 350 basis points from 26.5% to 23% on September 22, 2026. While Nigeria still has one of the highest policy rates among comparable African economies, the move has reduced its policy-rate advantage for investors seeking attractive real returns.

Following the rate cut, Nigeria’s policy rate stands 7.61 percentage points above its 15.39% headline inflation rate. Ghana, by comparison, has a 14% policy rate against inflation of 5%, giving it a wider 9 percentage-point differential. This means that although Ghana’s headline interest rate is significantly lower than Nigeria’s, its lower inflation has created a larger gap between the policy rate and consumer prices. For investors considering carry-trade opportunities, the differential can be an important factor when assessing potential returns.

The change also places Nigeria in a different position compared with other major African markets. South Africa has a 7% policy rate against 4.3% inflation, representing a 2.7 percentage-point gap, while Kenya’s 8.75% policy rate compares with inflation of 6.59%, producing a 2.16 percentage-point differential. Nigeria therefore continues to offer a substantially higher real policy-rate cushion than several peers, even after the CBN’s aggressive rate reduction. However, the latest figures show that a high nominal interest rate alone does not necessarily translate into the widest investment differential.

Financial Derivatives Company (FDC) Chief Executive Officer Bismarck Rewane said Nigeria remains attractive to carry-trade investors despite the reduction in the policy rate. According to Rewane, the real rate of return available to investors has fallen from above 11% to 7.61%, but remains relatively strong compared with several advanced economies. He also noted that the immediate reaction of the naira to the rate cut was limited, with the currency reportedly remaining around N1,387 in the parallel market before briefly moving towards N1,390.

The rate cut could, however, have implications for Nigerian savers and the wider financial market. Nigeria’s MPR has fallen from 27.25% in September 2024 to 23%, while inflation has also declined significantly over the same period. Rewane warned that lower interest rates could reduce returns on savings and encourage some investors to consider alternative assets. At the same time, potential increases in petrol, cooking gas and jet fuel prices could place renewed pressure on inflation. For Nigeria’s market, the next phase will therefore depend not only on the CBN’s interest-rate decisions, but also on whether inflation continues to fall fast enough to preserve the country’s appeal to domestic and foreign investors.
