Nigeria’s banking industry could be losing trillions of naira each year due to the Central Bank of Nigeria’s (Central Bank of Nigeria) high Cash Reserve Ratio (CRR), according to a new report by investment firm Chapel Hill Denham.
The report, titled “The Nigerian Banking Paradox: High Returns, Deep Discounts,”argues that although Nigerian banks are among the most profitable in Africa, they are still undervalued in the stock market compared to peers in countries like South Africa and Morocco. It says this gap is driven by tight regulations and broader economic uncertainty.
At the center of the issue is Nigeria’s unusually high CRR, currently around 50%. This rule requires banks to keep half of all customer deposits with the central bank without earning any interest. While the policy was introduced to control inflation, manage liquidity, and stabilise the naira, the report suggests it may now be limiting financial sector growth.
According to Chapel Hill Denham, this requirement is significantly weakening banks’ ability to lend and generate income. For every ₦100 deposited, ₦50 is effectively frozen at the central bank, while banks still pay interest to depositors. This creates what analysts describe as a major profitability strain.
The report estimates that if a 15% interest margin is applied, Nigerian banks could be losing about ₦2.5 trillion in potential annual earnings. This figure represents a large share of the sector’s profits and highlights what the report calls a structural “earnings drag” caused by the current policy.
It also argues that the CRR reduces credit availability in the wider economy. With less money available for lending, businesses may struggle to access funding for expansion, which could slow economic growth over time.
When compared globally, Nigeria’s CRR stands out as extremely high. Countries such as South Africa operate around 2.5%, Kenya at about 4.25%, Egypt at 16%, and Ghana at 15%, while Morocco has eliminated the requirement entirely. The global average for inflation-targeting economies is estimated at 5–10%, making Nigeria’s policy an outlier.
The report suggests that if the CRR were reduced from 50% to around 30–40%, it could unlock approximately ₦8 trillion back into the banking system. This, in turn, could generate up to ₦800 billion in additional annual pre-tax profits for banks.
However, despite these projections, investors appear to assume that the current strict policy will remain in place for the long term, contributing to low market valuations of Nigerian banking stocks.
At its February 2026 meeting, the Monetary Policy Committee (MPC) of the CBN retained tight liquidity measures, including CRR levels of 45% for deposit money banks and 75% for non-Treasury Single Account (TSA) public sector funds. Officials said the decision was necessary to control inflation, manage excess liquidity, and support exchange rate stability.
Some MPC members defended the policy, arguing that tight reserve requirements help prevent inflationary pressures and keep liquidity under control. Others noted that maintaining these measures supports overall financial stability even as interest rates adjust slightly.
Despite growing criticism from analysts, the CBN continues to maintain that high reserve requirements remain essential for stabilising the economy, even as debates continue over their long-term impact on lending and banking sector growth.
