Open Banking in Nigeria: What to Expect as the Framework Moves Toward Reality

Nigeria is on the verge of a structural change in how its financial system shares and uses data. For most Nigerians, banking has long meant navigating institutions that do not talk to each other, where your transaction history stays locked inside whichever bank holds your account, invisible to anyone else unless you print a statement and hand it over manually. Open banking is designed to end that arrangement.

The Central Bank of Nigeria formally approved the open banking rollout in April 2025, making Nigeria the first African country to commit to a regulated implementation of the framework. An August 2025 go-live date was set, though the deadline passed without a full launch. As of early 2026, industry implementation documents are with the CBN for final review, with a phased go-live now expected in the months ahead. The delay reflects caution, not abandonment.

How It Works, and Why It Took This Long

The concept is not new in Nigeria. The CBN began laying groundwork in February 2021 with a regulatory framework that defined API standards, consent rules, and tiered access roles. Operational guidelines followed in March 2023, reinforcing security requirements and introducing a public Open Banking Registry where all regulated participants — banks, fintechs, and licensed third-party providers — would be listed and verified.

At the center of the infrastructure is the Nigeria Inter-Bank Settlement System (NIBSS), which will manage two critical components: the Open Banking Registry itself, and a Consent Management System tied to customers’ Bank Verification Numbers. The BVN linkage is significant. It means that when a customer grants a third party access to their financial data, that permission is tracked, auditable, and revocable through a central system, not buried in a terms-and-conditions agreement nobody reads.

The framework uses a tiered model for data access, meaning not every participant gets access to everything. Account information, transaction history, and payment initiation each fall under different tiers with corresponding security requirements. This layered approach is intended to balance innovation with consumer protection.

One notable governance decision: rather than centralizing technical control under the CBN directly, Nigeria established Open Banking Nigeria, an independent industry body that coordinates API standards among banks, fintechs, and the regulator. The CBN also formed independent oversight committees staffed by financial sector professionals, following pushback from the banking industry against a more centralized structure.

What Changes for Consumers

The most immediate change will be in how financial service providers can see and use customer data, with explicit consent. Today, a fintech lender assessing whether to extend credit to a small business owner typically works with fragmented information: mobile transaction records, alternative data signals, or whatever the borrower can produce. Open banking would allow that same lender, with the customer’s permission, to access verified account balances, salary inflow patterns, and spending history directly from the customer’s bank.

As much as 70% of Nigerian bank account holders have historically been excluded from accessible bank-led credit. That is a structural problem rooted partly in data scarcity; banks and lenders cannot build accurate risk profiles for customers whose financial lives are fragmented across multiple institutions or conducted largely in cash. Open banking does not solve cash usage, but it removes one significant barrier: the inability to verify financial behavior across institutions.

The potential for better credit scoring is among the most consequential use cases. Nigeria’s digital lending sector has grown substantially — platforms disbursed $865 million in loans in 2025 alone, according to CBN data — but much of that growth has happened despite limited data access, sometimes resulting in subprime products and aggressive recovery practices. With richer, permissioned data available through standardized APIs, lenders can make more informed decisions, and borrowers stand to benefit from terms that actually reflect their financial reality.

Beyond lending, open banking creates the infrastructure for personal finance tools that pull account data from multiple banks into a single view, for automated savings products, and for payment initiation directly from bank accounts without routing through card networks.

The Fintech Angle

For Nigeria’s fintech sector, home to over 250 startups and the recipient of 70% of all startup funding on the continent, open banking represents both an opportunity and a compliance threshold. The CBN has restricted direct API access strictly to licensed and supervised entities, which means unlicensed startups building financial products will need to partner with licensed institutions to participate in the ecosystem. That requirement creates barriers for early-stage companies but also establishes a clearer structure for the market overall.

Companies like Mono and OnePipe have been building data aggregation infrastructure for years, positioning themselves precisely for a regulated open banking environment. Established neobanks and commercial banks that move quickly to publish functional APIs will gain early advantages in acquiring third-party integrations.

The UK, which has had open banking since 2018, offers a reference point: over 15 million users and roughly 30 million open banking payments per month by mid-2025. Nigeria’s market is structurally different — younger, more mobile-first, with higher informality — but the scale of adoption potential is arguably larger given the size of the unserved population.

The Risks Worth Watching

Data privacy is the clearest concern. Nigeria’s Data Protection Act provides a legal foundation, but enforcement capacity remains limited. Once financial data begins flowing across multiple institutions and third parties through standardized interfaces, the surface area for potential misuse expands. Consent management through the NIBSS system addresses part of this, but consumer awareness will matter as much as technical controls. If people do not understand what they are agreeing to, the consent mechanism becomes procedural rather than protective.

Interoperability is a technical challenge that will take time to resolve. Not all banks will implement APIs to the same standard or on the same timeline, and the practical value of the ecosystem depends on broad participation. A well-designed open banking registry helps, but it does not guarantee uniform execution.

Digital literacy and infrastructure coverage remain real constraints outside urban centers. For open banking to reach the populations most in need of expanded financial access — rural communities, informal sector workers, small traders — the mobile and connectivity infrastructure must be reliable enough to support data-driven financial services.

Where Things Stand

Nigeria has done the regulatory work. The frameworks exist, the governance bodies are in place, and the implementation documents are in front of the regulator. The remaining question is not whether open banking will launch, but how effectively it will function when it does.

For consumers, the practical shift will arrive gradually, through better loan products, more accurate account verification, and financial tools that reflect how people actually manage their money. For the financial industry, it marks a renegotiation of how data is owned, shared, and monetized. The CBN’s decision to proceed carefully, even at the cost of missing its own deadline, suggests an awareness that getting the infrastructure right matters more than the announcement.

The framework is built. What follows will depend on how consistently banks, fintechs, and regulators hold up their end of it.
