Commenting the Director and Chief Economist at Proshare Nigeria LLC, Teslim Shitta-Bey, has emphasised that net interest income remains the most crucial metric for evaluating Nigerian banks’ operational health, rather than just interest expenses or tax liabilities.
“First and foremost, interest expense by itself does not directly impact a bank’s lending capacity,” Shitta-Bey said. “What matters most to banks is their net interest income, the actual spread between what they earn and what they pay out. Tax is not an operational issue; as long as a bank is profitable, it will pay tax accordingly.”
On concerns about rising interest expenses amid liquidity challenges, Shitta-Bey pointed out that liquidity conditions, rather than just borrowing costs, determine banks’ capacity to lend. “With the current state of private placements and strong capital bases, many Nigerian banks are quite liquid. Some even have higher share capital than the Central Bank of Nigeria’s minimum requirements,” he noted.
Shitta-Bey also highlighted the role of key regulatory tools such as the Monetary Policy Rate and Cash Reserve Ratio.
“The MPR influences borrowing costs in the economy, while the CRR acts as a liquidity control mechanism. Banks maintain elevated share capital to ensure they have adequate shelter against risk, safeguarding financial stability,” he explained.
In his view, the bank’s strong capital positions and regulatory safeguards provide a cushion that supports lending activities despite fluctuations in interest expenses.
