Nigeria: Banks accelerate local data migration ahead of CBN’s 2027 deadline

Nigerian banks and other financial institutions are stepping up efforts to localise critical data infrastructure ahead of the Central Bank of Nigeria’s (CBN) January 1, 2027 deadline for data residency compliance.

The requirement mandates that payment transaction records, customers’ personally identifiable information (PII) and account ledgers be stored in data centres located within Nigeria, prompting financial institutions to review their technology architecture and cloud strategies.

The transition is expected to have significant implications for banks that have traditionally relied on international hyperscale cloud providers for scalability, computing capacity and access to global technology services.

Moving critical workloads, including real-time transaction processing systems, application programming interfaces (APIs) and fraud detection platforms, to domestic infrastructure presents technical, operational and cybersecurity considerations for institutions handling large volumes of financial transactions.

Banks face infrastructure and migration challenges

With Nigeria processing billions of electronic transactions each year, financial institutions face the challenge of meeting the new regulatory compliance requirements without compromising the availability and reliability of banking services.

Chief information officers and technology teams are therefore under pressure to assess local data-centre capacity, establish appropriate migration strategies and test infrastructure before transferring mission-critical workloads.

Industry stakeholders have also raised concerns about the availability of independent and vendor-neutral benchmarks for evaluating domestic cloud infrastructure.

They argue that local data centres must undergo comprehensive stress testing to demonstrate that they can support the performance, resilience and availability requirements of financial institutions.

Poorly planned migrations, they warn, could expose banks to service disruptions, performance issues and operational risks.

Local cloud providers expand capacity

Infrastructure providers are responding to the growing demand for domestic hosting by expanding local cloud capacity and developing services targeted at banks, fintechs and other organisations handling sensitive data.

MTN Nigeria, for instance, said its sovereign cloud infrastructure and engineering capabilities are designed to support financial institutions and fintech companies migrating workloads to locally hosted environments while reducing operational risks.

Lynda Saint-Nwafor, Chief Enterprise Business Officer at MTN Nigeria, said local data hosting could provide both operational and regulatory benefits.

“Hosting locally means lower latency, faster response times, and compliance with Nigeria’s data regulations. More importantly, it gives Nigerian businesses control, keeping sensitive financial, health, and government data within national borders.”

Balancing compliance with service continuity

The push towards domestic data residency is expected to accelerate investment in Nigeria’s data-centre, cloud computing and digital infrastructure ecosystem.

For financial institutions, however, compliance will require more than simply moving data from overseas servers to local facilities. Banks will need to assess infrastructure resilience, cybersecurity controls, disaster recovery arrangements, data governance and system performance throughout the migration process.

As the January 1, 2027 deadline approaches, the success of the transition will ultimately depend on how effectively financial institutions balance regulatory requirements with the need to maintain secure, resilient and uninterrupted banking services.

The shift could also strengthen Nigeria’s digital infrastructure ecosystem by increasing demand for local cloud services and encouraging greater investment in domestic data capacity.
