Debtors incur N8.4tn in interest payments to Nigerian banks in 2024

Nigerian banks had a remarkable year in 2024, benefiting from a high-interest rate environment that significantly boosted their earnings from loans to customers.
An analysis of ten publicly traded banks on the Nigerian Exchange revealed that these banks collectively earned a staggering N8.41 trillion in interest from customer loans, more than double the N4.08 trillion from the previous year.
The surge in interest income follows the Central Bank of Nigeria’s (CBN) aggressive monetary policies, which included raising the benchmark interest rate to 27.5% in 2024. This move was aimed at controlling inflation and stabilizing the economy. The sharp rate hikes created a favorable environment for banks, which responded by raising their lending rates and significantly increasing income from loan interest.
Banks see growth in loan portfolios
By the end of 2024, the total loan portfolio of these banks reached N51.36 trillion, reflecting a 37.6% year-on-year increase. This growth was driven by a combination of rising loan demand and higher interest rates, which allowed banks to increase their earnings from loans.
- Banks also saw a boost in earnings from other financial assets such as government securities, corporate bonds, and interbank placements, which generated N6.66 trillion in interest income—up from N2.7 trillion in 2023.
- Overall, interest income accounted for a large portion—72.4%—of the total earnings for these banks. The remainder came from fees, commissions, trading income, and other services.
Despite the overall growth, the banks experienced pressure on funding costs, as the Central Bank’s tight monetary stance drove up the cost of funds. Some banks also faced an increase in non-performing loans (NPLs), with the average NPL ratio climbing from 4.1% in 2023 to 4.5% in 2024.

Implications for the banking sector
The performance of Nigerian banks in 2024 illustrates the significant impact of rising interest rates on their profitability. However, this surge in interest income has not come without challenges. Higher interest rates also led to increased borrowing costs, which in turn affected borrowers’ ability to meet their obligations.
Additionally, the higher interest rate environment contributed to a rise in non-performing loans (NPLs), indicating that the growth in loan income was somewhat offset by a deterioration in loan quality.
As we look to 2025, the outlook for the banking sector remains positive in terms of interest income, although concerns over loan quality and the impact of high borrowing costs may persist.
