Fintech Interoperability Across African Markets: Africa’s Next Big Bet on Digital Trade

African regulators, banks and fintechs are racing to make money move as seamlessly across borders as it does within a single mobile wallet — and Fintech Interoperability Across African Markets is rapidly becoming a core test of whether the African Continental Free Trade Area (AfCFTA) can deliver on its promise of a truly integrated digital economy. From Lagos to Johannesburg, the push to link payment systems, harmonise rules and standardise data flows is reshaping how businesses and consumers transact, and why it matters for Africa’s growth story.

Why Fintech Interoperability Across African Markets Is Suddenly a Hot Policy Topic

Interoperability used to be a technical footnote; today, it sits at the centre of continental trade and digital policy. The AfCFTA Protocol on Digital Trade, adopted by African Union members and updated through 2024, explicitly requires states to promote interoperability between digital payment and settlement systems and to support real-time, affordable cross-border digital payments using common and open standards.[African Union – AfCFTA Digital Trade Protocol] This is a clear signal that payments infrastructure is now treated as trade infrastructure.

The emerging Fintech Annex to this protocol goes further, calling on governments to collaborate on standards, encourage cross-border partnerships between fintech companies, and align rules for licensing and supervision.[Afronomicslaw – Fintech Annex analysis] For South African fintechs — from payment service providers to digital banks — this creates a more predictable regulatory horizon for scaling into the rest of the continent.

For African businesses, the stakes are both practical and strategic:

  • Cutting the cost and friction of cross-border payments in local currencies.
  • Reducing reliance on offshore correspondent banking routes for intra-African trade.
  • Unlocking regional scale for fintech products instead of siloed, single-market offerings.
  • Supporting formalisation and financial inclusion by making cross-border digital payments usable for SMEs and informal traders.

PAPSS and the Infrastructure Behind Cross-Border Digital Payments

The Pan-African Payment and Settlement System (PAPSS), spearheaded by Afreximbank and supported by the AfCFTA Secretariat, is currently one of the most concrete expressions of Fintech Interoperability Across African Markets.[PAPSS – About Us] PAPSS is a financial market infrastructure designed to allow instant cross-border payments in local currencies, reducing the need for hard currency intermediaries and lowering transaction costs.

According to recent analyses, PAPSS now connects central banks, commercial banks, payment service providers and fintech companies across a growing number of African states, and is integrated with multiple domestic payment switches to route and settle transactions rapidly.[SAIIA – PAPSS policy brief] The system supports three key processes — instant payment, pre-funding and net settlement — to manage liquidity and risk while still delivering near real-time transfers.[PAPSS – How It Works]

Recent developments underscore its scaling ambitions:

  • Central banks, including Egypt’s, have signed agreements to join PAPSS to boost intra-African trade and financial integration.[Ahram Online – PAPSS-Instapay link]
  • PAPSS is being linked to national instant payment schemes to create smoother consumer and SME experiences across borders.
  • The system is positioned as foundational infrastructure that African fintechs can build on, rather than a consumer-facing product itself.

For South African banks exploring deeper regional integration, PAPSS offers an alternative to the traditional, often costly correspondent banking model. For local fintech players, it offers a way to plug into continental flows without having to negotiate bilateral technical and commercial agreements in every market.

Regulation, Standards and the Politics of Digital Interoperability

Interoperability is not only about APIs and settlement rails; it is also about law, supervision and politics. The AfCFTA Digital Trade Protocol’s article on digital payments commits states to make their regulations publicly available, adopt international and regional payment standards, and promote open APIs and fair access for both financial and non-financial institutions.[AfricanLII – Digital Trade Protocol text] This matters for South African fintechs pushing for level playing fields when entering other African markets dominated by incumbent banks or mobile network operators.

Alongside the protocol, regional groupings like SADC are working on financial inclusion and payment interoperability frameworks. Recent SADC guidance highlights cross-border harmonisation of mobile money rules to support frictionless transactions between member states, recognising that unaligned standards can strand users at borders even when handsets and apps are technically capable.[FinMark Trust – SADC Financial Inclusion Forum]

However, several challenges persist:

  • Fragmented regulation: Different licensing regimes for payment service providers, e-money issuers and digital lenders make it hard to scale a single compliance strategy across markets.
  • Data and KYC frictions: Cross-border authentication and electronic KYC requirements are not yet standardised, complicating onboarding and risk management.
  • Competition concerns: Opening access to payment infrastructure may be resisted by incumbents worried about losing market share, even as continental policy pushes for fair competition.
  • Cybersecurity and trust: Harmonising cybersecurity standards and incident reporting across jurisdictions is essential to avoid weakest-link vulnerabilities.

Seen from South Africa, these issues are not abstract. Local regulators and industry bodies are closely watching how continental rules for data flows, digital identities and fintech licensing will interact with domestic frameworks such as the Financial Sector Regulation Act and the Protection of Personal Information Act.

South Africa’s Role in a Continental Interoperability Push

South Africa enters the Fintech Interoperability Across African Markets conversation with relatively advanced payments infrastructure, a strong banking sector and a vibrant fintech ecosystem. Domestic real-time payment rails, card ecosystems, and emerging open finance initiatives give local players technical depth and operational experience.

South African companies are already active across the continent. Banks such as Standard Bank and Absa operate in multiple African markets, while fintechs from payment gateways to remittance players are building cross-border offerings. For these firms, interoperability is not theoretical — it shapes everything from integration costs to customer experience and risk models.

Key areas where South Africa can exert outsized influence include:

  • Technical standards: Contributing to API, messaging and settlement standards adopted under AfCFTA annexes on cross-border digital payments and fintech.
  • Regulatory leadership: Sharing supervisory experience on issues such as prudential requirements for payment institutions, open banking/open finance governance, and consumer protection.
  • Market access: Using South Africa’s role in regional blocs like SADC to advocate for interoperable schemes that benefit SMEs, migrant workers and informal traders.
  • Innovation sandboxes: Leveraging experimental regulatory sandboxes to test cross-border use cases in partnership with other regulators.

At the same time, South African firms face competitive pressure from nimble mobile money operators and platform-based fintechs in East and West Africa. Interoperability could level the playing field, but it could also intensify competition as barriers to entry fall.
