For years, the narrative in Nigerian finance was clear: traditional banks were the slow-moving giants, and fintechs were the nimble challengers winning over the masses with speed and reliability. But by 2025, that script has been flipped.
After a massive investment in core infrastructure, Nigeria’s “Big Four” banks GTCO, First Bank, UBA, and Zenith Bank processed a staggering $208 billion (₦286 trillion) in mobile transactions in 2025, signaling that the reliability gap that once favored fintechs has all but vanished.
The scale of digital adoption within traditional banking has reached unprecedented heights. Total instant payments in Nigeria hit ₦1.07 quadrillion in 2024, and the momentum has only accelerated.
2025 Mobile Transaction Volume by Bank:
• Zenith Bank: ₦104.14 Trillion ($75.74B)
• GTCO: ₦72.40 Trillion ($52.66B)
• First Bank: ₦58.00 Trillion ($42.18B)*
• UBA: ₦51.65 Trillion ($37.57B)
*First Bank figure represents the first nine months of 2025.
A standout metric is GTCO’s “Pay-with-Transfer” feature, which saw an explosive 7,814.8% surge, growing from ₦131.5 billion in 2024 to ₦10.4 trillion in 2025.
The ₦415 Billion Upgrade
This resurgence wasn’t accidental. Between 2024 and 2025, GTCO, UBA, and Zenith collectively funneled ₦415.36 billion ($302M) into core technology overhauls.
Major shifts included:
• GTBank: Migrated to Finacle (Infosys).
• Zenith Bank: Switched to Flexcube (Finastra).
While these migrations initially caused frustrating outages for millions, the long-term payoff has been a drastic reduction in failed transactions and system instability—the very pain points that originally drove users toward fintech apps like OPay, Moniepoint, and PalmPay.
What This Means for the Ecosystem
For Customers: A Battle of Value, Not Just Uptime
Reliability is now the baseline, not a luxury. Users no longer need to “bridge” their money keeping bulk savings in a bank while moving daily spending cash to a fintech. As bank apps become as fast as fintechs, the competition will shift toward pricing, user experience (UX), and tailored credit.
For Fintechs: The End of “Easy” Growth
The “reliability edge” is gone. Fintechs now face a dual threat:
1. Retention over Acquisition: With banks fixing their tech, fintechs must work harder to keep high-frequency users from drifting back to their primary bank accounts.
2. Regulatory Gravity: The CBN is pushing major fintechs toward National Microfinance Bank licenses, saddling them with the same compliance costs, oversight, and physical presence requirements as traditional banks.
For the Banks: A New Revenue Powerhouse
Digital transformation is paying off in cold, hard cash. Since 2024, the Big Four have generated massive e-banking income:
• UBA: ₦461.94 Billion
• Zenith: ₦169.18 Billion
• First Bank: ₦167.92 Billion
• GTCO: ₦121.29 Billion
The Bottom Line
Nigeria has seen the steepest decline in cash usage globally, with a 59% drop over the last decade. As the nation moves toward a truly cashless economy, the war for the consumer’s wallet is entering a second phase.
The first phase was about who could make the transfer work. This next phase will be about who can offer the most value on top of that transfer whether through instant credit, better savings yields, or superior customer support. Traditional banks have proved they can build the pipes; now, they must prove they can keep the users happy.
