Nigeria’s reported decision to require locally generated payment transaction data to be stored and managed within the country is an important development for West Africa’s digital economy. It reflects a growing recognition that the location and control of financial data are no longer purely technical questions. They are becoming matters of regulatory oversight, economic security, operational resilience and national digital strategy.
According to a report by Premium Times, the Central Bank of Nigeria has directed banks, fintech companies and other payment service providers to store and manage payment transaction data generated in Nigeria locally, with full compliance expected from 1 January 2027.[1] Similar reports have also appeared in The Guardian Nigeria and Punch, indicating that the measure is intended to strengthen data security, improve regulatory supervision and give authorities faster access to financial information when conducting monitoring or investigations.
The decision will have immediate implications for Nigerian financial institutions, particularly those that currently depend on overseas cloud regions or foreign infrastructure for parts of their payment operations. However, its significance extends beyond Nigeria. It raises an increasingly important question for Ghana and other African economies: where should critical national data be stored, who should control it, and what infrastructure is required to protect it?
Data sovereignty is about more than server location
Financial transaction records are among the most sensitive forms of data produced by a modern economy. They support payment processing, fraud detection, regulatory supervision, customer protection, taxation and the investigation of financial crime. The location of this information can determine which laws apply, which authorities can obtain access and how quickly an institution can respond to a regulatory request or security incident.
This is why data sovereignty has become such an important part of the digital-policy debate. However, sovereignty should not be reduced to the physical location of a server. Data may be stored within a country while its administration, encryption keys, software dependencies or legal control remain elsewhere. Genuine sovereignty therefore requires clarity about ownership, access, jurisdiction, security, portability and the ability to continue operating when a technology provider fails or a cross-border connection is disrupted.
Local hosting can strengthen regulatory access and reduce dependence on infrastructure outside the country. It can also support investment in domestic data centres, connectivity, cloud services and technical skills. Nevertheless, these benefits will only be realised when localisation is supported by infrastructure capable of meeting the security and availability requirements of financial services.
Local infrastructure must also be resilient
Keeping information within national borders does not automatically make it secure. A local server room with limited backup power, weak cooling, a single network connection or inadequate physical protection may introduce greater risk than a professionally operated facility elsewhere. The relevant question is therefore not simply whether data is local, but whether the environment supporting it is sufficiently resilient.
Banks, fintech companies and payment providers operate services that customers expect to be available continuously. The supporting infrastructure must be designed to withstand failures involving power, cooling, connectivity, equipment and human activity. It must also provide appropriate fire detection and suppression, access control, continuous monitoring, incident management and tested disaster-recovery arrangements.
Migration itself creates another layer of risk. Payment platforms are complex, interconnected systems, and moving them cannot be treated as a routine transfer of archived files. Institutions must understand their application dependencies, network requirements, backup arrangements, encryption controls and recovery objectives before beginning a migration. A rushed localisation programme could cause disruption or create new vulnerabilities if organisations are required to move before suitable capacity, skills and processes are in place.
Nigeria’s reported policy should therefore be understood not only as a data-governance measure, but also as a test of the maturity of the country’s wider digital infrastructure ecosystem.
Ghana’s current position
Ghana has not introduced an equivalent blanket rule requiring all domestic payment transaction data to be stored exclusively within the country. Nevertheless, the regulatory direction is becoming clearer. The Bank of Ghana is placing greater responsibility on financial institutions to understand where their data is held, how external technology providers manage it and whether the underlying infrastructure can support critical financial services.
According to the Bank of Ghana’s Cyber and Information Security Directive 2026, regulated financial institutions must consider data sovereignty when assessing cloud arrangements and must obtain Bank of Ghana approval before transitioning to cloud services. The Directive also requires institutions to conduct due diligence on providers, retain appropriate control over sensitive data and ensure that regulators can access relevant information, audits and facilities when necessary.
The Directive further requires sensitive information stored with cloud providers to be encrypted, while encryption keys should remain with the regulated financial institution rather than the provider. Cross-border transfers are not prohibited outright, but they must be supported by proper safeguards and approved by the Bank of Ghana. This indicates that Ghana’s present approach is based on regulatory control and risk assessment rather than complete data isolation.
Importantly, the Directive does not consider cloud governance separately from physical infrastructure. It establishes requirements for power, cooling, fire protection, connectivity, security, monitoring, disaster recovery and contractual service levels in data centres used by financial institutions. The Bank of Ghana states that uptime commitments should reflect the “high availability expectations for critical financial systems”.
This is a significant development. It demonstrates that Ghana is moving beyond general cybersecurity guidance towards closer examination of the facilities, networks and service providers on which its financial system depends.
Where Ghana is likely to be heading
Ghana’s immediate direction appears to be towards stronger regulatory oversight of data residency, cloud adoption, third-party providers and operational resilience. Financial institutions will increasingly be expected to map their technology dependencies, assess the jurisdictions in which their information is processed and demonstrate that critical systems can be recovered after a serious disruption.
As more financial services move online, the pressure for greater domestic control is also likely to grow. Mobile money, digital banking, payment applications, identity systems and emerging artificial-intelligence services are creating larger quantities of economically valuable and sensitive data. Regulators will need to decide which categories of information may be transferred internationally, which require additional safeguards and which should remain available within Ghana.
This does not necessarily mean that Ghana will or should reproduce Nigeria’s reported policy in exactly the same form. A blanket localisation requirement could increase costs, restrict access to specialist cloud services and create concentration risk if too many institutions depend on a small number of domestic providers. A more effective approach would classify data according to its sensitivity and strategic importance, then apply proportionate requirements to each category.
Where Ghana should head
Ghana should develop a clear national framework for critical-data residency that complements the Bank of Ghana’s existing cybersecurity and cloud requirements. This should define the types of financial, government, health, identity and other sensitive data that require local storage, a locally controlled copy or a domestic disaster-recovery environment. Less sensitive information could continue to move across borders under approved legal, technical and contractual safeguards.
Any future framework should prioritise resilience rather than location alone. Organisations handling critical information should be required to demonstrate access to redundant power and cooling, diverse network connections, strong physical and cyber security, continuous monitoring, tested recovery arrangements and transparent audit rights. Localisation should never become a substitute for these controls.
Ghana should also introduce a phased migration-readiness process for institutions that rely heavily on overseas infrastructure. This would require organisations to identify where their data resides, document which services depend on foreign cloud regions and maintain credible plans for moving or recovering critical workloads. Preparing gradually would be safer and more commercially sustainable than waiting for a sudden regulatory deadline.
At the same time, Ghana should preserve regional and international interoperability. The African Union Data Policy Framework calls for stronger African control over data while also supporting secure cross-border data flows and a shared continental digital market. Ghana’s aim should therefore be to strengthen national control without creating unnecessary barriers to innovation, investment or cross-border services.
Building the infrastructure behind digital trust
The broader opportunity for Ghana is not simply to retain more data within its borders. It is to establish itself as a trusted location for hosting and managing critical African workloads. The country already possesses several of the foundations required to achieve this, including international submarine-cable connections, national fibre infrastructure, internet exchanges, a growing fintech sector and professionally operated data-centre capacity.
At Onix Data Centres, our Tier IV-certified, carrier-neutral facility in Accra is designed to support organisations whose systems require high levels of availability, security and connectivity. The facility provides redundant power and cooling, diverse network routes, layered physical security, continuous monitoring and expected uptime of 99.995%.
Nigeria’s reported policy is therefore relevant to Ghana even if the two countries ultimately take different regulatory approaches. It shows that African governments are beginning to treat financial data as a strategic asset and the infrastructure supporting it as a matter of national importance.
Ghana should use this moment to develop a balanced framework that protects sensitive information, supports secure cross-border activity and encourages further investment in domestic digital infrastructure. Regulation can establish the direction, but data sovereignty will only become meaningful when it is supported by resilient facilities, reliable connectivity, skilled professionals and institutions prepared to manage their data responsibly.
