For the better part of a decade, the story of Nigerian banking technology has been written on smartphone screens. Account opening went from paper forms to a few taps. Transfers stopped being a waiting game. And financial services slipped neatly into the palm of every customer’s hand. But by 2027, that story is set to take a sharp turn. The next big battle will not be fought on the customer interface. It will be waged deep inside the engine room of the financial system.
The early wave of digital banking was, in many ways, a clever disguise. Banks and fintechs draped sleek new front ends over aging core systems. It worked. Customers got a better experience, and institutions avoided the painful surgery of replacing critical infrastructure. But beneath the surface, a tangle of integrations, middleware, and manual workarounds has been quietly accumulating. Every new product, every new payment route, every new external partner adds another layer of strain to systems never designed for a real-time, API-driven world.
That strain is about to become impossible to ignore. The Central Bank of Nigeria’s Payments System Vision 2028, launched in June 2026, has set the stage for a more interconnected and secure financial landscape. Meanwhile, the Nigeria Inter-Bank Settlement System is rolling out the National Payment Stack, a platform built on ISO 20022 messaging. This isn’t just a technical upgrade. It brings richer transaction data, end-to-end traceability, real-time settlement visibility, and support for open banking, multi-currency flows, and cross-border dealings.
All of this means the old model of a fixed core surrounded by isolated digital projects is reaching its limits. As Pavel Shumsky, chief marketing officer at banking technology firm Velmie, puts it: “By 2027, the market will be less concerned with whether an institution has a mobile application and more concerned with what sits behind it.” The institutions that pull ahead, he argues, will be those that can plug into new payment infrastructure, launch products without a major redevelopment effort, and keep a consistent financial record across every channel and provider.
The shift is fundamentally about architecture. The next cycle favours platforms that separate customer journeys from the systems of record beneath them. Banks can keep core infrastructure where it still works, while adding a modern layer for product configuration, integrations, and digital delivery. This staged approach avoids the high-risk gamble of replacing the entire banking estate in one go. The old binary choice between keeping a legacy core and ripping it out is fading. A smarter path preserves what’s reliable and moves product logic and customer services into a more adaptable platform.
The arrival of ISO 20022 is often framed as a messaging upgrade, but its real value is in the depth of information it carries. Older formats offered little context. Operations teams were left with a transaction value and a basic reference, then had to chase down the purpose, the beneficiary, or the invoice behind it. ISO 20022 changes that with structured data that supports automation, better reconciliation, and sharper fraud detection. But that value only materialises if the internal platform can actually hold and use the information. If the core system reduces rich data to a bare ledger entry, the opportunity is lost.
Shumsky stresses this point: “Structured payment data gives institutions the opportunity to automate work that is still handled manually. It can improve reconciliation, shorten investigations and give risk teams a clearer view of the transaction. Those gains depend on whether the banking platform can preserve the data and make it available throughout the operating process.” The goal is a seamless thread connecting the original payment instruction to the ledger entry, settlement status, and operational history, so staff don’t have to stitch together fragments from half a dozen systems.
Open banking is another force reshaping the market. The Central Bank has laid down operational guidelines covering participation, consent, security, and responsibilities. But the commercial payoff depends on how seriously banks take it. A narrow, box-ticking approach will just expose the bare minimum interfaces. A strategic one puts APIs at the heart of the architecture, letting the same services power digital channels, fintech partnerships, and embedded finance. As Shumsky notes, “Open banking will create value only when banks move beyond publishing APIs and redesign the operating model around them.” The real prize is distributing banking capabilities more widely while keeping firm control over consent, data ownership, and service delivery.
That kind of flexibility demands disciplined governance. Institutions have to know where information came from, which platform is the source of truth, and how a failed external request will be handled. This is driving demand for orchestration technology that sits between the core system, customer channels, and third-party providers. It manages routing, data exchange, and exceptions, giving banks a consistent way to add new connections without rebuilding everything each time.
Nigeria has no shortage of banking software, payment providers, or digital apps. The hard part is making them work as one coherent service. That’s why technology selection is increasingly about delivery capability. Who owns the architecture? How are integrations tested? Who keeps the platform running after launch? Velmie’s model, for instance, involves a dedicated team that stays on through implementation and beyond, covering configuration, integration engineering, digital channels, and production operations.
Shumsky sees the market moving away from isolated software purchases. “Banks need technology partners that understand the full operating environment and remain accountable when a change affects several systems. The quality of the platform matters, but so does the ability to keep it working as the institution develops.”
The road to 2027 is clear. The National Payment Stack is bringing more advanced capabilities and richer data. Open banking is multiplying the connections between institutions and outside businesses. Artificial intelligence is making reliable operational information more valuable than ever. Against that backdrop, the old fixed-core-plus-digital-side-projects model is becoming a liability.
The institutions that lead will not be defined by how many services they cram into an app. Their edge will come from an architecture that lets them launch quickly, operate reliably, and expand without straining the systems underneath. The mobile app was just the opening act. The real show is now happening behind the scenes.
