Nigerian banks are losing approximately N2.5 trillion in potential earnings every year due to the Central Bank of Nigeria’s high Cash Reserve Ratio (CRR), a new report by investment banking firm Chapel Hill Denham has revealed.
The report, titled The Nigerian Banking Paradox: High Returns, Deep Discounts, highlights how the 50% CRR requirement is significantly constraining bank profitability despite the sector posting some of the strongest returns on equity in Africa.
According to the analysts, for every N100 in customer deposits, banks are forced to keep N50 locked up at the CBN with zero interest, while still paying depositors between 5% and 12%. Applying a conservative 15% net interest spread, this policy creates an annual earnings drag of roughly N2.5 trillion equivalent to about 60% of the banking sector’s gross earnings in Q3 2025.
Restrictive Regulations Weigh on Lending
The report argues that the high CRR, originally introduced to manage liquidity and stabilise the naira, is now limiting banks’ ability to create credit and support economic growth.
“Nigerian banks operate under a uniquely restrictive regulatory perimeter, including a 50% cash reserve ratio,” the report stated. This framework, it added, structurally suppresses reported returns even as banks expand regionally.
Chapel Hill Denham noted that Nigeria’s CRR is among the highest globally. For comparison, South Africa operates at 2.5%, Kenya at 4.25%, Ghana at 15%, Egypt at 16%, while Morocco has reduced its ratio to 0%. The global median for inflation-targeting countries is between 5% and 10%.
Potential Relief from CRR Reduction
The analysts suggested that a gradual reduction of the CRR from 50% to between 30% and 40% over the next two to three years would be both economically and politically feasible. Such a move could release around N8 trillion back into the banking system and generate an additional N800 billion in annual pre-tax profits for banks.
This, they believe, would boost lending to the real sector and help narrow the wide valuation discounts at which Nigerian bank stocks currently trade compared to peers in South Africa and Morocco.
CBN Defends Tight Policy
The Central Bank of Nigeria has maintained the high CRR, with the Monetary Policy Committee retaining it at 45% for deposit money banks and 75% for non-TSA public sector deposits as of February 2026. MPC members have consistently defended the policy as necessary to anchor inflation, manage excess liquidity, and support exchange rate stability.
Despite the strong defence, analysts continue to argue that the long-term opportunity cost of the current CRR regime on credit creation and economic growth deserves urgent review as macroeconomic conditions gradually normalise.
The Chapel Hill Denham report underscores a growing debate within Nigeria’s financial sector: balancing macro-prudential stability with the need to unlock greater lending capacity to drive private sector-led growth.
