Nigeria’s financial markets are presenting a unique paradox, with banks continuing to secure yields above 17% on government securities, despite the Central Bank of Nigeria (CBN) having reduced its benchmark interest rate by 350 basis points in September 2026.
This sustained high yield environment is challenging the CBN’s efforts to stimulate economic activity through lower borrowing costs and raises questions about the efficacy of monetary policy transmission in the country.
The CBN’s Monetary Policy Committee (MPC) had, in its September meeting, moved to cut the Monetary Policy Rate (MPR) from an undisclosed higher level to help reduce the cost of funds for businesses and consumers, thereby aiming to spur lending and investment. Typically, such a significant reduction in the benchmark rate would lead to a corresponding decline in yields on short-term government instruments and interbank rates, lowering the overall cost of capital.
However, market data indicates that bank investors are still finding opportunities to earn robust returns from instruments like Open Market Operations (OMO) bills and Treasury Bills. This persistence in high yields suggests that underlying market forces are currently outweighing the CBN’s direct policy signals.
Market Dynamics Defy Monetary Policy Objectives
Several factors appear to be contributing to the market’s defiance of the CBN’s rate cut. Persistent inflationary pressures remain a significant concern for investors, who demand higher returns to compensate for the eroding value of money. The National Bureau of Statistics (NBS) had previously reported inflation rates hovering at elevated levels, driving expectations of continued price increases.
Furthermore, the federal government’s ongoing borrowing requirements continue to create demand for funds, maintaining upward pressure on yields. When the government issues new debt instruments, it often has to offer competitive rates to attract sufficient subscription, especially from institutional investors like banks who are significant players in the fixed income market. This dynamic ensures that even with a lower MPR, the demand for government paper can keep yields elevated.
Liquidity conditions in the financial system also play a crucial role. While the CBN may attempt to inject liquidity or signal lower rates, the actual availability and cost of funds can be influenced by other factors, including the CBN’s own OMO auctions, foreign exchange market interventions, and commercial banks’ reserve requirements. If liquidity remains tighter than ideal, banks will maintain higher lending rates to protect their net interest margins.
The current scenario presents a mixed bag for the Nigerian banking sector. On one hand, the sustained high yields allow banks to maintain profitability from their holdings of government securities and from placing surplus cash with the CBN. This could potentially offset some of the initial concerns that the rate cut would immediately compress their net interest margins and overall earnings.
On the other hand, the higher cost of funds in the market could undermine the CBN’s objective of stimulating economic growth through cheaper credit. Businesses and individuals seeking loans may still face high interest rates from commercial banks, as the banks’ own cost of funds remains high, regardless of the MPR. This could hinder investment, expansion, and job creation, which were key targets of the rate reduction.
Analysts suggest that the CBN may need to employ additional tools beyond just the MPR to achieve its desired market outcomes. This could involve more direct interventions in the money market, adjustments to liquidity management frameworks, or closer coordination with fiscal policy to reduce government borrowing pressure. The effectiveness of monetary policy in Nigeria hinges on its ability to influence market rates comprehensively, and the current divergence presents a critical test for the apex bank.
