The Role of Open Banking in Ghana’s Finance Sector: ASJ Intelligence Brief

From regulatory draft to ecosystem movement — how customer-permissioned data sharing is reshaping Ghana’s financial landscape

Executive Introduction

For years, Ghana’s financial sector has operated on a paradox. The country boasts one of Africa’s most advanced payment systems—mobile money processing over 97 percent of all digital transaction volumes and accounting for 72 percent of total value . Yet deeper financial services—credit, savings, insurance, pensions—remain shallow, particularly for small businesses and low-income households . Banks’ digital channels handle less than 1 percent of transaction volumes, even as mobile money has become the default for everyday payments .

The missing link is data.

A customer who has reliably repaid mobile microloans cannot access a bank loan because the bank cannot see that repayment history. A fintech that could offer better credit terms lacks access to banking transaction data that would verify income. A small business that wants to switch to a more competitive provider must start from scratch, re-entering information and rebuilding trust. The data exists, but it sits in silos—owned by individual institutions, inaccessible to competitors, invisible to the customers who generated it.

Open banking is the solution to this fragmentation. It is a regulatory framework that allows customers to grant permission for their financial data to be shared securely with other regulated providers through standardised digital connections (APIs) . It enables new services to be built, better products to be offered, and genuine competition to emerge.

This report examines the role of open banking in Ghana’s finance sector: the regulatory framework being developed by the Bank of Ghana, the Open Data Exchange (OpenDX) platform designed to power it, the stakeholders driving adoption, the benefits for consumers and businesses, and the challenges that could undermine implementation. The evidence suggests that Ghana is positioning itself as a continental leader—but success depends on moving from regulatory project to ecosystem movement.

Part 1: What Open Banking Actually Means

Before examining Ghana’s specific implementation, understand the core concept. Open banking is often misunderstood as “banks giving away data for free” or “fintechs taking over banking.” Both are wrong.

The Definition

Open banking is a framework that enables customer-permissioned data sharing between regulated financial institutions . A customer—whether an individual or a business—can authorise one institution to share their financial data with another. The data is not public; it is not sold; it is shared only with the customer’s explicit consent and only for specific purposes .

The key distinction: In traditional banking, the customer’s data belongs to the bank. In open banking, the customer owns their data and can direct where it flows .

How It Works

What Open Banking Is NOT

Open banking is not a free-for-all. The Bank of Ghana’s draft directive explicitly requires: data sharing only with explicit customer consent; secure, standardised APIs for all transfers; participation restricted to regulated financial institutions; and compliance with data protection and cybersecurity standards .

A Deputy Governor framed it plainly: “Open banking will not succeed only as a regulatory project… It must be a movement, an ecosystem movement” .

Part 2: The Regulatory Framework — Bank of Ghana’s Open Banking Directive

The Bank of Ghana has been developing an open banking framework since 2022, recognising that mobile money’s success created the foundation but not the full financial ecosystem . The milestone event was the publication of the Draft Open Banking Directive in January 2026 .

The Draft Directive

The draft directive establishes clear rules for open banking participants around data protection, security protocols, and operational standards . It applies to all regulated financial institutions (RFIs), including universal banks, development banks, savings and loans companies, microfinance institutions, rural and community banks, and payment service providers .

Key provisions include:

“The central point of this directive lies in the proposition of providing an enabling environment for customers of financial institutions to access a myriad of personalised permissible financial products and services,” the BoG stated. “Influenced by the ongoing developments in financial technology, regulatory reforms and Ghana’s expanding digital infrastructure, this open banking directive is a pioneering initiative set to significantly improve Ghana’s financial services sector” .

The Open Data Exchange (OpenDX)

To make open banking operational, the BoG is establishing Open Data Exchange (OpenDX) — a legal entity that will serve as the public digital infrastructure platform for data sharing .

OpenDX’s responsibilities include: governing API standardisation and regulatory technical standards; providing access for participants to manage consent requests; delivering real-time notifications for consent management; monitoring compliance and suspending non-compliant participants .

The National Payment Systems Strategy (2025–2029)

The open banking directive sits within a broader strategic framework. Speaking at the Public National Payment Systems Workshop in Accra, First Deputy Governor Dr. Zakari Mumuni announced that the new National Payment Systems Strategy (2025–2029) will “prioritise interoperability, open banking and digital infrastructure as key enablers of growth and inclusion” .

The strategy will introduce data-sharing frameworks, electronic Know Your Customer (eKYC) systems, and trusted digital identity solutions to “make participation in the payments ecosystem easier and more cost-effective for both banks and non-bank entities” . “The transition to the new strategy represents not just continuity, but transformation. It is an opportunity to reimagine our payment systems for the next phase of Ghana’s digital economy; one that is more resilient, inclusive and globally competitive,” Dr. Mumuni stated .

Part 3: The Stakeholders — Who Is Driving Open Banking Forward

Open banking cannot succeed through regulation alone. It requires active participation from banks, fintechs, mobile money operators, and regulators working in concert.

The Bank of Ghana: Convener and Enforcer

The central bank plays multiple roles: regulator (setting rules through the directive), infrastructure provider (establishing OpenDX), capacity builder (forming a Technical Working Group on Open Banking Readiness), and cheerleader (urging banks to lead, not follow).

Governor Dr. Johnson P. Asiama was characteristically direct at the GAB Industry Thought Leadership Event: “The future of banking is open, not siloed” . He warned that banks are ceding too much ground to non-bank players, with digital channels handling less than 1 percent of transaction volumes . “Banks must lead, not follow. Open banking is not about giving ground to new entrants; it’s about reclaiming trust, redefining convenience and renewing relevance” .

GhIPSS: Technical Anchor

The Ghana Interbank Payment and Settlement Systems (GhIPSS) is positioned to lead technical implementation. CEO Clara B. Arthur explained that “interoperability already offered a pathway to open banking and API standardisation in Ghana’s payments landscape. Common API standards across the banking and fintech ecosystem would make integration with the national payment infrastructure much easier and more efficient” .

She committed that “GhIPSS will champion work with banks and fintechs to address issues around governance and integration. Once we have national standards, the Bank of Ghana can roll out the right policies” .

Mobile Money Operators: The Incumbent Platforms

Mobile money operators are both competitors and potential collaborators. MTN MobileMoney already operates an open API platform allowing partners to build services on its infrastructure . Chief Product and Services Officer Sylvia Otuo-Acheampong noted that “it took a while for partners to trust MobileMoney’s open API, but once they did, it created new opportunities for innovation and access” .

She urged capacity development: “To grow access through apps, the API must be the central integration point. Open API is the way into the future for aggregation to move the industry forward” .

Banks: The Reluctant Incumbents

Banks are the most critical—and most resistant—stakeholders. Open banking requires them to share customer data they have historically treated as proprietary. Yet Governor Asiama framed it as an existential imperative: without open banking, banks risk becoming “marginal players in a rapidly evolving landscape” .

Early adopters may gain competitive advantage; laggards may find their customers moving to fintechs that offer better products using bank data.

IMANI and Policy Analysts: The Watchdogs

Selorm Branttie, Vice-President of IMANI Center for Policy and Education, has emerged as a key voice arguing that open banking APIs “solve a lot of issues for service providers — ensuring trust and better responsiveness to the market” .

He cautioned, however, that Ghana’s open banking efforts must harmonise with the National Data Harmonization Framework, currently being developed to streamline digital identity, data governance, and access management. “Doing so will consolidate Ghana’s position as Africa’s fintech leader—ahead of Nigeria and on par with Kenya—with the most robust regulatory ecosystem in West Africa” .

Part 4: The Benefits — Why Open Banking Matters

If implemented effectively, open banking could transform Ghana’s financial sector across several dimensions.

Benefit 1: Enhanced Financial Inclusion

Despite high mobile money penetration, deeper financial services remain inaccessible for many Ghanaians. More than 4 million Ghanaians have accessed mobile microloans, but few have migrated to formal banking products .

Open banking enables a graduation pathway: a customer builds a credit history through mobile money repayments, then uses that data to access bank loans, insurance, or savings products . The BoG’s new frameworks explicitly aim to “expand financial access and support SMEs,” which often struggle to secure affordable credit .

Benefit 2: SME Access to Credit

Small and medium enterprises (SMEs) are the backbone of Ghana’s economy but remain underserved by traditional lending. Banks lack visibility into SME cash flows, making risk assessment difficult.

Open banking allows lenders to access real-time transaction data from SME bank accounts and mobile money wallets—with permission—enabling better credit decisions and potentially lower interest rates.

As Dr. Mumuni explained, the frameworks aim to support “improved access to payment services, financing and cross-border trade” .

Benefit 3: Increased Competition and Innovation

Open banking lowers barriers to entry for fintechs. Instead of building their own data infrastructure, fintechs can plug into OpenDX and build innovative products on top of existing data—account aggregation, personal financial management, switching tools, personalised lending, budgeting and forecasting, cross-institution comparisons.

When customers can easily compare products and switch providers, incumbents have strong incentives to improve pricing, service, and innovation.

Benefit 4: Customer Empowerment and Portability

The core principle of open banking is customer ownership of data. Customers can authorise their bank to share transaction history with a budgeting app, allow a fintech to analyse spending patterns and recommend better products, or enable a new lender to assess creditworthiness without manual paperwork.

Switching providers becomes seamless—no more re-entering information, no more lost history. This portability is the ultimate competitive pressure on incumbents.

Benefit 5: A Unified Digital Identity Layer

GhIPSS CEO Clara Arthur argued that “a shared digital ID layer on top of everything would allow us to achieve all that has been mentioned” . By integrating open banking APIs with Ghana’s digital identity infrastructure, citizens could access multiple financial and government services through a single, trusted authentication framework—reducing fraud, lowering onboarding costs, and accelerating digital adoption .

Part 5: The Challenges — What Could Derail Implementation

The potential is significant, but the obstacles are equally real.

Challenge 1: Bank Readiness and Resistance

The most immediate challenge is whether banks will embrace open banking or resist it. Governor Asiama’s warning that banks’ digital channels handle less than 1% of transaction volumes reflects deep structural issues—many banks have underinvested in digital infrastructure and API capabilities.

Without active bank participation, OpenDX will have limited data to share.

Challenge 2: Data Protection and Security

Open banking expands the attack surface for cybercriminals. More data sharing means more potential points of compromise. The BoG’s requirement that participants connect to FICSOC or maintain a licensed Security Operations Centre is essential, but smaller institutions may struggle to meet these standards .

Customer trust depends on robust security. A single high-profile breach could set back adoption by years.

Challenge 3: Consent and Accountability

Future of Finance Dialogues participants spent significant time on “the gap between policy and customer reality, especially on questions like consent and accountability” .

Key open questions: how is consent requested in plain language (not dense legalese)? How is data secured throughout the sharing chain? Who owns responsibility to fix issues when a customer journey crosses multiple organisations? In a connected ecosystem, “not my platform” stops being a useful answer .

Challenge 4: API Standardisation

Common API standards are the technical prerequisite for open banking. Without them, each integration is a custom project—expensive, slow, and error-prone.

GhIPSS has committed to leading standardisation efforts, but coordination across dozens of banks and fintechs is complex . Some fintechs may not be prepared to adopt API-based service delivery, “which remains a key challenge in scaling digital financial products” .

Challenge 5: Regulatory Coordination

Branttie’s warning about harmonisation is critical. Ghana’s open banking initiative does not exist in isolation. It must align with the National Data Harmonization Framework, data protection laws, cybersecurity regulations, and sector-specific rules for banking, telecoms, and payments .

Without coordination, conflicting rules could create compliance nightmares.

Part 6: The Competitive Context — Ghana vs Nigeria vs Kenya

Ghana is positioning itself as a continental leader in open banking—but it faces competition from other markets.

Branttie’s ambition is explicit: harmonisation will “consolidate Ghana’s position as Africa’s fintech leader—ahead of Nigeria and on par with Kenya—with the most robust regulatory ecosystem in West Africa” .

Part 7: The Future — What Happens Next

Immediate (2026)

The Bank of Ghana will finalise the Open Banking Directive following stakeholder consultation . OpenDX will be established as a legal entity with clear governance and technical standards . The Technical Working Group on Open Banking Readiness will chart a roadmap for interoperability, product layering, and consent-driven data sharing .

Short-Term (2027)

Pilot implementations will likely begin with a small set of participating institutions. Open banking-enabled products will emerge—account aggregation, credit scoring, switching tools. The e-Cedi digital currency pilot may integrate with open banking infrastructure .

Long-Term (2028–2030)

If successful, open banking could extend beyond financial data to become open finance—sharing data across insurance, pensions, investments, and utilities. Regional interoperability with ECOWAS partners could enable cross-border open banking, unlocking intra-African trade finance . Ghana’s ecosystem could serve as a model for other West African markets adopting similar frameworks.

Dr. Mumuni’s vision for the National Payment Systems Strategy was clear: “It is an opportunity to reimagine our payment systems for the next phase of Ghana’s digital economy; one that is more resilient, inclusive and globally competitive” .

Conclusion: From Regulatory Project to Ecosystem Movement

Open banking in Ghana is at a pivotal moment. The regulatory framework is being drafted, the infrastructure (OpenDX) is being built, and the stakeholders—central bank, GhIPSS, mobile money operators, banks, fintechs, policy analysts—are engaged. The ambition is continental leadership.

But regulation alone does not change markets. As one Deputy Governor noted, “Open banking will not succeed only as a regulatory project… It must be a movement, an ecosystem movement” .

The movement requires banks to invest in APIs and overcome resistance to data sharing. It requires fintechs to build products that customers actually want. It requires regulators to enforce security and data protection while enabling innovation. It requires customers to trust that their data will be used responsibly—and to exercise their consent rights.

The prize is a financial sector where customers own their data, smaller institutions compete on merit, and deeper services reach underserved populations. Ghana has the payment rails. It has the mobile money foundation. It has a central bank willing to push.

The question is not whether open banking will come to Ghana. The question is whether Ghana’s financial ecosystem will move together to make it work—or fragment into winners and losers, leaving the promise unfulfilled.

The answer depends on what banks, fintechs, and regulators do next. Not on the policy paper. On the execution.
