Open Banking in Nigeria: The Gap Between Regulation and Reality
Nigeria became the first country in Africa to launch a clearly stipulated open banking regulation. The CBN published its framework in 2021, issued detailed operational guidelines in 2023, and banks began implementation on the August 2025 go-live date. By most measures, the regulatory work is done.
And yet the gap between what the framework envisions and what Nigerian consumers actually experience is wide. A well-designed set of rules and a well-functioning market are not the same thing, and in open banking, the distance between the two is where the real challenge sits.
Understanding that distance matters for compliance teams, but also for any institution that wants to build financial products people will actually use. The regulation is not the problem. The distance between the regulation and the ground is.
What the CBN’s Framework Actually Requires
The CBN’s open banking framework operates on a layered model. At the top is the regulatory framework itself, which establishes the principles: consumer consent, data portability, and controlled third-party access. Beneath that are the 2023 operational guidelines, which translate those principles into technical and operational requirements.
Under the guidelines, all API interactions must use OAuth 2.0 for authentication and Transport Layer Security (TLS) for data in transit. These are globally recognised standards, and any institution participating in open banking is expected to meet them without exception.
The Open Banking Registry (OBR) adds another layer of accountability. Only accredited API providers and consumers can operate within the framework, meaning institutions must be vetted before they can access or share customer data through open banking channels. The CBN also requires regular risk assessments and alignment with internationally recognised information security standards such as ISO 27001.
What the guidelines establish is a credible baseline. The question is what happens between that baseline and the consumer’s actual experience.
What Reality Looks Like on the Ground
Nigeria’s fintech sector did not arrive at open banking with a clean slate. The lending app crisis of the late 2010s and early 2020s left a specific, well-documented pattern of harm: apps harvesting contact lists without clear consent, aggressive debt-shaming tactics, and unauthorised access to personal data well beyond what users had agreed to share.
The Nigeria Data Protection Commission has since sanctioned a number of these operators, and the CBN has tightened its licensing requirements. But the damage to consumer confidence was real and lasting.
For open banking, this history creates a concrete problem. Most Nigerian consumers cannot meaningfully distinguish between a regulated open banking integration and the kind of app that caused those abuses. Both involve granting a third party access to financial data. The consent screens look similar. The technical process feels the same. The regulatory distance between them is substantial; the experiential distance is almost nothing.
This is the most important dimension of the gap. The regulation assumes a consumer who understands what they are consenting to and trusts the institutional infrastructure enough to act on that understanding. The market reality is a consumer base with legitimate, earned reasons to be cautious, and that caution does not dissolve because the CBN issued guidelines.
There is also a financial literacy dimension worth acknowledging. Open banking works as designed when users can make active, informed choices about data sharing. That requires understanding what an API is, what access a third-party app actually receives, and what the practical difference is between sharing account balance data and sharing full transaction history.
For a large portion of the Nigerian adult population that open banking is supposed to serve, particularly those who are newly banked or digitally underserved, that baseline understanding does not yet exist. The framework is built for an informed user. Reaching the users who matter most requires building for an uninformed one.
The Regulatory Stack Has Its Own Gaps
The challenge is not only between institutions and consumers. There are genuine ambiguities within the regulatory framework itself, and they create operational uncertainty for anyone building on open banking infrastructure. At a high level, the issue is this: technical rules and legal rules do not always align.
The CBN’s operational guidelines and the Nigeria Data Protection Act 2023 are both in force, and both apply to any institution participating in open banking. Alongside the NDPA 2023, the General Application and Implementation Directive sets out how data protection obligations are applied in practice across sectors. The CBN framework sets the technical and operational standards. The NDPA 2023 and GAID together set the legal standards for data handling. Meeting the CBN’s requirements does not mean you have met theirs.
Data Retention
The CBN guidelines do not define how long a third-party provider may retain customer data once a user revokes consent. The NDPA 2023 requires data to be kept only as long as necessary for its stated purpose, but does not specify what “necessary” means in the context of an active API relationship.
A provider that received six months of transaction history for a credit assessment has no clear, consistent instruction on when that data must be deleted. Institutions are resolving this through their own policies, which means the answer varies depending on who you ask.
Consent Revocation
The NDPA 2023 gives data subjects the right to withdraw consent, and that right must be honoured promptly. But the operational sequence is unresolved. If a user revokes consent mid-transaction during an active loan disbursement initiated based on shared account data, does the transaction complete before data access ends? Does it halt immediately? Who is responsible for communicating the outcome to the user? These are not edge cases. Any institution offering credit products through open banking channels will encounter them.
Third-Party Liability
This is arguably the most commercially significant gap. If a breach occurs at the level of an API consumer rather than the originating bank, the NDPA 2023 assigns accountability to any entity that processes personal data. That could implicate both the bank that shared the data and the third party that failed to protect it.
The CBN guidelines place obligations on registered participants but do not resolve how liability is apportioned when multiple participants are involved in the same data chain. Until enforcement action, regulatory guidance, or case law settles this, institutions are effectively writing their own rules through the indemnity clauses in their API agreements. That is not a stable foundation.

Where Compliant Institutions Are Still Getting It Wrong
Meeting the CBN’s technical requirements is necessary but not sufficient. There are failure patterns that persist even among registered, technically compliant participants. They matter because they are the layer that consumers actually encounter.
Consent UX
The CBN requires that consent be informed and specific. In practice, many consent flows bury the relevant permissions in lengthy terms, use language that assumes financial and technical literacy, or structure the process so that “agree to everything” is the path of least resistance.
A user who technically consented but did not meaningfully understand what they agreed to is a regulatory and reputational liability. When things go wrong, the consent log protects the institution. It does not protect the relationship.
Third-Party Data Chains
When a bank shares customer data with an API consumer, the consumer may depend on other service providers, such as cloud infrastructure, analytics platforms, and credit bureaus. The end user has no visibility into this chain. They consented to sharing their data with a single entity. They may not know how many others that data passes through. In a market where confidence in institutional data handling is already fragile, this opacity compounds the trust problem rather than resolving it.
Token Lifecycle Management
OAuth 2.0 tokens have defined expiry periods, and the security model depends on those windows being enforced rigorously. In practice, token management is a known and exploited attack surface.
An institution may be fully compliant at the point of token issuance, logging the grant, recording the consent, but have weak processes for monitoring active tokens, rotating credentials, and revoking access when a user ends their relationship with a third-party provider.
Tokens that remain technically valid after consent is withdrawn are an open door. This is how an app can continue accessing a user’s financial data after they believe they have disconnected it. The user had no warning it was there and no practical way to close it.
None of these failures require non-compliance to occur. They are the gaps within compliance, and they erode user trust in ways that audits and certification frameworks are not designed to catch.
What Closing the Gap Looks Like
The organisations that get this right share a common characteristic: they treat privacy as product design rather than a compliance layer applied after the product is built.
The practical difference shows up in specifics. Consent flows are written in plain language and tested with actual users, not drafted by legal teams and shipped unchanged. Revocation is easy to find and works immediately, without being buried in settings or requiring a customer service call.
Data access dashboards, which the CBN guidelines encourage but do not uniformly mandate, show users exactly which third parties have access to their data and when that access was granted. These are design decisions, not compliance requirements. The institutions that make them deliberately are building something the regulation cannot mandate on its own.
It also shows up in how institutions handle incidents. A breach or unauthorised access event is inevitable for any sufficiently complex system. The question is whether the institution has a clear, tested response protocol, notifies affected users promptly, and communicates honestly about what happened. That response behaviour, not the breach itself, is what shapes long-term consumer confidence.
Building systems this way costs more upfront. It requires UX designers, compliance officers, and security engineers working at the same stage of product development, rather than sequentially. Institutions that skip that integration tend to follow a familiar pattern, the same one behind most technology project failures in Nigeria. But those that invest in this approach end up with something no framework can mandate: genuine trust.

The Business Case for Closing the Gap
Some institutions treat regulatory compliance as the ceiling. In Nigeria’s open banking environment, it is the floor.
Regulatory Exposure
The NDPA 2023 carries financial penalties of up to 2% of gross annual revenue for data protection violations. For any institution of meaningful scale, that exposure is material. But the reputational cost of a public data incident in a market where consumer trust is already fragile is harder to quantify and potentially more damaging. Nigeria’s fintech sector has seen how quickly a breach can hollow out a brand that took years to build.
Commercial Gatekeeping
International financial partners, payment processors, and institutional investors are applying data governance assessments as a standard part of due diligence. A Nigerian fintech seeking a commercial partnership with a European payments network, or investment from a fund with its own ESG obligations, will be assessed on data governance maturity before commercial terms are discussed.
What that assessment looks at is straightforward: documented consent management processes, evidence of regular risk assessments, a tested incident response framework, and clarity on how third-party data access is controlled. An institution that cannot produce those will not close those conversations, regardless of how strong its product is.
Competitive Positioning
Organisations that understand the gap between regulatory compliance and genuine consumer trust and deliberately work to close it are building a position that rules alone cannot create. As Nigeria’s open banking market matures, the technical baseline will become table stakes. What will separate the players that thrive from those that merely survive is whether consumers actually choose to use what they have built.
Frequently Asked Questions
Conclusion
Nigeria’s open banking framework is more than a policy document. It represents a serious attempt to build financial infrastructure that extends access, enables competition, and puts consumers in control of their own data.
But a well-designed framework and a well-functioning market are not the same thing. The gap between them, in consumer trust, in regulatory alignment, in institutional execution, is where open banking in Nigeria will succeed or stall.
Closing that gap is not primarily a compliance challenge. It is a product design challenge, a trust-building challenge, and an execution challenge. The institutions that treat it as all three will be the ones that define what open banking actually becomes in Nigeria. Those who treat it only as a compliance exercise will eventually find out that their users chose someone else.
