Nigeria's Central Bank dropped a significant rule this week, one that could reshape the country's booming digital payments space. Any licensed financial institution that controls more than 25% of the merchant acquiring market will be capped at 15% market share on the consumer side, and the same logic applies in reverse. The rule takes effect December 31, 2026, giving companies time to adjust, but the message is clear: no single player gets to own both ends of the transaction.
The timing is pointed. Nigeria's digital payments ecosystem processed 1.2 quadrillion naira, roughly $884.78 billion, in 2025 alone, and the institutions moving through that money have been quietly building empires on both sides of the checkout counter. Banks and fintechs have spent years expanding beyond their original lanes, and the CBN's new framework is a direct response to how fast that convergence is happening.
The companies most likely to feel the pressure are the fintechs that built their names on merchant payments and are now making moves into consumer banking. Paystack acquired Ladder Microfinance Bank in January. Flutterwave secured a microfinance bank licence in April after acquiring open banking startup Mono. Both companies have been working to turn payment users into full banking customers, and this new cap puts a ceiling on how far that strategy can go without trade-offs.
Traditional banks are not off the hook either. An institution like United Bank for Africa could find itself caught by the rule if it pushes aggressively into merchant acquiring while holding a dominant position in consumer banking. The question now is which players will choose to double down on one side, and which will try to restructure before the deadline hits.
