Angolan kwanza in RTGS across SADC — regional framework to study — and what comes next

SADC's regional integration architecture is full of instruments that exist on paper well before they operate in practice — protocols signed, strategies adopted, roadmaps published, with implementation trailing years behind ratification. The SADC Free Trade Area, launched in 2008, is one example: more than 85 percent of intra-regional trade now carries zero-duty status, a genuine achievement, but one reached over more than a decade of uneven member-state implementation. Payment-system integration has followed a similar arc. SADC-RTGS has operated since the system's earlier years, but for the whole of that period it settled in a single currency, the South African rand, even as SADC's own rhetoric described a bloc of fifteen diversified, sovereign economies.

This week's confirmation that the Angolan kwanza became the system's second settlement currency is the first concrete break from that single-currency design in over a decade of operation. The governance mechanism behind it — the SADC Committee of Central Bank Governors, chaired by Lesetja Kganyago, Governor of the South African Reserve Bank, working jointly with Manuel Tiago Dias, Governor of Banco Nacional de Angola — is worth studying in its own right, because it is the operational body that will determine whether this becomes a genuine multi-currency framework or an isolated bilateral exception dressed up as regional policy.

What kind of instrument this actually is

It matters, analytically, that this change came from a technical committee of central bank governors rather than from a summit-level protocol or a new legal instrument. SADC's integration toolkit includes formal protocols requiring ratification across member states — a slow, often multi-year process — and administrative decisions that a standing committee can implement directly within an existing system's operating rules. The kwanza's addition to SADC-RTGS, as SADC's own announcement of the change describes it, falls into the second category: an operating-rules change within an existing platform, not a new treaty-level commitment binding all fifteen members.

That distinction has real consequences for how quickly the framework can evolve. An operating-rules change can, in principle, add a third or fourth currency without waiting for the slower ratification cycle that governs SADC's treaty instruments. The Committee of Central Bank Governors has already signalled that further currencies, including the Botswana pula, are being prepared for onboarding — a sequencing decision that a standing technical body can execute far faster than a formal protocol amendment could.

Where implementation will diverge

The honest analytical question is whether every member state's banking system is equally ready to operate a multi-currency settlement environment. SADC-RTGS's broader institutional history — a platform designed to give all participating member states real-time cross-border settlement — describes an ambition of universal participation, but readiness to actively use a second or third settlement currency is not evenly distributed across fifteen economies with very different banking-sector depth and correspondent banking relationships. SADC's broader account of its regional integration milestones describes the system's original ambition; it does not, on its own, establish which member states have built the operational capacity to use a multi-currency version of it today.

[TK]: a member-state-by-member-state breakdown of technical readiness to process direct kwanza settlement has not been confirmed by any source reviewed for this piece and should be treated as an open implementation question rather than an assumed fact.

Strategic foresight behind the sequencing

The choice to add the kwanza second — after thirteen years of rand-only operation, and immediately ahead of a signalled pula addition — is itself a piece of strategic sequencing worth reading closely. Angola's trade and interbank transaction volume with the rest of SADC, at roughly US$3.77 billion in 2025, is large enough to justify a dedicated settlement corridor, and Angola's Banco Nacional has a governor sitting on the same regional committee overseeing the system. Choosing the largest non-rand economy with the most direct institutional access as the second currency, rather than starting with a smaller economy, suggests the Committee of Central Bank Governors is sequencing additions by transaction volume and institutional readiness rather than by alphabetical or political convenience.

That is a defensible integration strategy, and one consistent with international standard-setting bodies such as the Bank for International Settlements' Committee on Payments and Market Infrastructures, which has long argued that payment-system reform should follow demonstrated transaction demand rather than symbolic inclusiveness. It is also, on the evidence available, an assumption rather than a confirmed policy stated by SADC itself. [TK]: SADC has not published an explicit stated rationale for the sequencing order of currency additions to SADC-RTGS.

A precedent other regional blocs will watch

SADC is not the only African regional economic community wrestling with the gap between trade-integration ambition and payment-system reality. The Common Market for Eastern and Southern Africa and the East African Community have each pursued their own regional payment and settlement initiatives, with mixed pace of implementation. A SADC precedent showing that a standing technical committee can add settlement currencies incrementally, based on transaction volume, offers a workable template other blocs could study rather than reinventing.

Whether that precedent gets studied, or whether it remains a SADC-specific footnote, will depend on how visibly SADC documents and communicates its own sequencing logic going forward. [TK]: no source reviewed confirms any formal engagement between SADC's Committee of Central Bank Governors and equivalent bodies in other African regional economic communities on this specific mechanism.

What comes next

The framework-level test to watch is whether the Committee of Central Bank Governors publishes, or is asked to publish, an explicit roadmap and criteria for further currency additions — rather than announcing each one individually as it happens. A published sequencing framework would signal a mature, rules-based integration mechanism; continued one-off announcements would suggest the process remains ad hoc, however sound each individual decision.

Analysts and policy researchers tracking SADC's monetary integration trajectory should treat the pula's signalled onboarding as the next concrete data point against which to test whether this is becoming a systematic framework or remaining a series of well-chosen exceptions.
