IN SHORT: Zenith Bank and Guaranty Trust Holding Company collectively earned N283 billion ($183 million) from account maintenance charges and digital banking fees in 2025 alone. The figure signals that Nigeria’s biggest banks have decisively shifted their revenue model from lending margins toward transaction fee income as digital volumes compound.
Nigeria’s two largest banks by market capitalisation, Zenith Bank and GTCO, jointly earned N283 billion ($183 million) from account maintenance and digital banking fees in 2025, underlining the structural shift in how Nigeria’s financial sector generates income as mobile transactions replace branch activity.
- The combined fee haul from just two banks marks a sharp departure from the lending-led income model that defined Nigerian banking for decades. As interest rate cuts reduce net interest margins, fee income from digital channels is becoming the primary growth engine.
- Zenith Bank recently completed its acquisition of Paramount Bank Kenya, becoming the fourth Nigerian lender in East Africa and signalling that the fee-income model is now being exported across the continent.
- Nigeria’s CBN introduced new PoS agent banking guidelines on April 1, 2026, restricting agents to a single financial institution and mandating registered devices from approved locations. The reform is expected to consolidate agent banking market share toward platforms with scale, with OPay among the primary beneficiaries given its existing agent network of millions.
- The CBN’s digital banking infrastructure is deepening: Nigeria’s BVN database reached 68.6 million registrations in March 2026, and broad money supply sits at N123.36 trillion, the largest monetary base in sub-Saharan Africa.
- For context, Zenith and GTCO’s combined digital fee income of $183 million in a single year surpasses the total startup funding raised by Nigeria in all of Q1 2026 ($78 million), illustrating the scale gap between established financial institutions and the challenger ecosystem.
The fee income story matters structurally. Nigerian banks were historically valued on their ability to generate spread income from government securities and corporate loans. That model is under pressure from falling interest rates and increased competition for creditworthy borrowers. Banks that built early digital infrastructure, as Zenith and GTCO did, are now harvesting recurring, high-margin fee income from the country’s 100 million-plus mobile banking users at a cost approaching zero per transaction.
The Bigger Picture: Nigeria’s banking sector is generating McKinsey-grade returns from digital infrastructure built over the last decade. With Africa’s banking revenues crossing $107 billion continent-wide in 2025 and return on equity running at nearly double the global average, the continent’s largest financial institutions are no longer emerging market stories. They are delivering developed-market profitability metrics from a growing base of 1.4 billion potential customers. Zenith and GTCO’s fee income is the clearest proof point.
