Open Banking in Nigeria: What the CBN Framework Means for Consumers
For more than a decade, Nigerian banks have held onto a kind of data nobody else could see: years of transaction histories, spending patterns, and repayment behaviour, locked inside each institution’s own systems. A customer with accounts at three different banks had no simple, secure way to let a lender or savings app see that combined picture, even with their consent. Open banking is the regulatory and technical answer to that problem, and Nigeria has spent the better part of five years trying to build it.
A framework that has taken longer to launch than to write
The Central Bank of Nigeria issued its Regulatory Framework for Open Banking in February 2021, making Nigeria the first country on the continent to put a formal open banking policy on paper. Two years later, in March 2023, the CBN followed with detailed Operational Guidelines spelling out how banks, fintechs, and other licensed players were expected to actually share data once the system went live.
Then came the wait. In April 2025, the CBN signalled that open banking would finally launch commercially, with TechCabal reporting at the time that banks were expected to begin sharing customer data from August that year. August arrived and passed without an official go-live, and the CBN stayed publicly quiet on why. By October, a CBN official confirmed at a Moonshot by TechCabal panel that the system still had not gone live, and that the regulator was still finalising governance structures and a common API template across banks. The CBN’s own fintech policy report from February 2026 has since pointed to a phased rollout stretching across the rest of this year, with implementation now expected to land in stages through mid-2026, and the Nigeria Inter-Bank Settlement System (NIBSS) tapped to run the central registry of approved participants.
How the system is meant to work
Once live, open banking sorts participants into risk tiers, running from low-risk players handling only basic, non-sensitive data up to fully licensed banks and fintechs cleared to handle a customer’s complete financial profile. Institutions operate either as API providers, releasing data, or API consumers, drawing on it, and some will do both. Every exchange is meant to be anchored to a customer’s consent, tied to their Bank Verification Number, so a person can authorize, monitor, and withdraw access to their own account information rather than leaving it buried in blanket terms-and-conditions language. NIBSS, which already runs much of Nigeria’s interbank payment infrastructure, has been positioned to host both the registry of approved participants and the consent management system underpinning all of this.
What it could change for ordinary customers
The most immediate consumer benefit sits with credit. Nigeria’s formal lending market has long struggled with a basic problem: banks underwrite cautiously and turn away people without collateral or a paper trail, leaving a large share of account holders effectively excluded from affordable credit. Open banking gives lenders a way to assess a person’s real transaction history and cash flow instead of relying on collateral alone, which is the logic behind data-driven lending tools that fintechs such as Mono, OnePipe and Lendsqr have been building in anticipation of the framework going live. Savings, budgeting, and insurance products stand to benefit in similar ways, since providers will be able to design offerings around verified spending behaviour rather than guesswork.
The framework also assigns clear liability when something goes wrong. Under the operational guidelines, whichever institution loses or mishandles customer data carries responsibility for the breach, and the CBN has said participants will be expected to report incidents within a short, defined window. That distinction matters for ordinary users because it draws a line between a bank’s negligence and a customer’s own carelessness, something that has often stayed murky in disputes over unauthorised transactions in Nigeria’s banking system.
The trust question that remains
None of this works if customers do not understand what they are consenting to, or if banks treat API access as a compliance exercise rather than a genuine shift in how they handle customer data. The CBN does have a record of forcing reluctant compliance once it sets a hard deadline, as seen with the Bank Verification Number rollout from 2014 and the NUBAN account numbering standard before it. But open banking asks banks to do something more uncomfortable than enrolling customers in a new identifier: it asks them to treat customer data as something the customer, not the bank, ultimately controls. Whether that principle survives contact with an industry that has historically guarded its data closely is the real test still ahead.
For now, Nigerian consumers are not yet experiencing open banking in any practical sense. The framework exists, the institutions are being lined up, and the registry has a home at NIBSS, but the system itself had not gone live nearly a year after its first promised launch date. What it ultimately means for consumers will depend less on the documents the CBN has already published and more on how faithfully banks, fintechs, and the regulator follow through once the system is actually switched on.
