Nigeria’s banking sector is facing an estimated annual earnings loss of N2.5 trillion due to the Central Bank of Nigeria’s (CBN) elevated Cash Reserve Ratio (CRR), according to a report by Chapel Hill Denham. The investment banking firm highlighted that this policy, while intended to manage liquidity and curb inflation, significantly constrains bank profitability and lending capacity.
The report, titled “The Nigerian Banking Paradox: High Returns, Deep Discounts,” indicates that for every N100 deposited, banks must set aside up to N50 in non-interest-bearing reserves. This creates a substantial earnings drag, estimated at 60 percent of Q3 2025 gross earnings, assuming a 15 percent net interest spread.
Chapel Hill Denham argues that the long-term costs of the high CRR may now outweigh its benefits, especially when compared to other African economies. For instance, South Africa’s CRR is 2.5 percent, Kenya’s is 4.25 percent, Ghana’s is 15 percent, Egypt’s is 16 percent, and Morocco has reduced its ratio to zero. Nigeria’s CRR remains significantly higher, fundamentally reshaping bank balance sheets and earnings.
The firm projected that lowering the CRR from 50 percent to 30 percent could inject approximately N8 trillion into the banking system and increase annual pre-tax profits by about N800 billion. Investors, however, appear to be pricing Nigerian bank stocks based on the assumption that the restrictive reserve regime will persist, contributing to discounted market valuations.
Despite these concerns, the CBN has maintained that elevated reserve requirements are crucial for macroeconomic stability. At its February 2026 Monetary Policy Committee meeting, the CRR was retained at 45 percent for Deposit Money Banks, 16 percent for Merchant Banks, and 75 percent for non-TSA public sector deposits, to maintain tight monetary conditions and manage inflationary and exchange rate pressures.
In a separate development, Access Holdings Plc achieved a significant milestone by crossing the N1 trillion profit-before-tax threshold for the first time. However, the group's dividend payments were withheld by regulators. This decision stemmed from concerns that Access Holdings' foreign banking investments had reached 19.4 percent of its shareholders’ funds, exceeding the CBN’s regulatory threshold of 10 percent. This highlights a shift in regulatory focus from pure profitability to capital resilience and systemic stability.
Meanwhile, Tatum Bank reported a Profit Before Tax of N1.7 billion in its first eight months of operation for the 2025 financial year. The bank also established a deposit base of over N117 billion and confirmed it met the CBN’s recapitalisation requirements, underscoring its financial strength and commitment to compliance.
The banking sector's increasing investment in technology is also notable. Eight of the top 10 companies with the highest technology expenditure in 2025 were financial institutions, collectively spending approximately N628.1 billion. This reflects a strong commitment to digital infrastructure, cybersecurity, and platform modernization as banks compete for transaction volumes.
