RTGS Expansion Across SADC: Capital, Bankability and Where Firms Can Capture Value

September 10, 2023

A payments system that clears in real time still has to be paid for by somebody, and the question of who funded SADC's regional settlement network, and who carries the risk of running it, sits awkwardly alongside the more comfortable story of integration achieved. SADC's own account of its progress treats the Real Time Gross Settlement platform as a completed milestone. For finance teams and capital allocators, the more useful question is what the system's funding and risk structure imply about who can bank on it, and where the next investable gap sits.

As of 10 September 2023, the public record confirms that SADC-RTGS has operated since October 2018, connecting 85 participating banks, central and commercial, across all member states except Comoros, on a multi-currency platform that settles cross-border payments same-day rather than over the several days correspondent banking previously required. What the record does not disclose is the ownership and cost-recovery model behind that infrastructure: who bears settlement risk if a participating bank fails to fund its position, and how participation fees are structured for smaller commercial banks weighing whether to join.

The thesis for capital allocators is that a regional settlement rail of this scale, spanning 15 member states, is itself a piece of financial infrastructure worth pricing, whether as a credit-risk input, a bankability signal for trade finance, or a gap to be filled by private capital where the public system does not yet reach.

Funding a regional utility

Real Time Gross Settlement systems are, by design, central-bank infrastructure: they eliminate the credit and settlement risk that arises when payments net out over time rather than clearing individually and immediately. SADC's account of its integration record credits the platform with enabling member states "to settle payments among themselves in real-time," a description consistent with a central-bank-operated utility rather than a commercially financed one. That matters for how the system should be read financially: it is public infrastructure, not a fintech product competing for market share, and its costs are more likely recovered through participation fees levied on member banks than through a return-seeking capital structure.

For a regional bank treasurer, the practical question is what it costs to join the 85-bank network relative to the correspondent-banking fees, float costs and foreign-exchange spreads the system displaces. The public sources reviewed do not disclose participation fee schedules. [TK: fee structures and cost-recovery mechanics for SADC-RTGS participation were not published in the sources reviewed.] That gap is itself useful: a bank evaluating whether to join should request fee terms directly from its central bank rather than assume the system is cost-neutral.

Risk allocation and who carries currency exposure

A multi-currency settlement platform does not eliminate foreign-exchange risk; it relocates where that risk is managed. Under the previous correspondent-banking model, currency conversion and exposure were typically absorbed, and priced, by the correspondent bank itself, often outside the region. A regional RTGS system that settles directly in participating currencies shifts that exposure closer to the transacting banks, and by extension to their corporate clients, unless a matching regional hedging or liquidity facility exists alongside it.

The record reviewed does not describe such a facility. That absence is the clearest capital-market opportunity in this story: a treasury desk, development finance institution or private liquidity provider offering short-term funding or hedging calibrated to SADC-RTGS settlement cycles would be filling a gap the settlement system itself does not close. Bankability still depends on a layer of regional risk management the public record does not yet show has been built.

Bankability for trade finance

For trade financiers, a documented, real-time settlement rail is a modest but real underwriting input. Faster, more certain settlement reduces the window during which a financed transaction is exposed to counterparty or currency risk, feeding into how a bank prices a letter of credit or invoice-discounting facility within the 85-bank network. Whether banks are yet adjusting trade-finance pricing to reflect that reduced exposure is not disclosed in the sources reviewed, and would require confirmation from lenders active in the corridor.

That gap is itself the commercial signal: a bank or development finance institution able to demonstrate, with actual settlement data, that SADC-RTGS transactions carry lower default and delay risk than correspondent-routed equivalents would have a defensible basis to price trade finance more competitively for firms banked within the network, a modest but real point of differentiation in a crowded regional lending market.

Where private capital can still add value

The public record's silence on participation costs, risk-sharing arrangements and liquidity backstops is not a weakness in the story so much as a map of where private capital, rather than public infrastructure, still has room to operate. Regional payment aggregators, correspondent-replacement fintechs and trade-finance platforms built to interoperate with SADC-RTGS rather than compete with it represent a narrower, better-defined opportunity than trying to build competing settlement rails from scratch.

The near-term decision for an investor or operator is therefore less about entering the settlement layer itself, public infrastructure with 85 incumbent participants, and more about building services around it: liquidity management, hedging and trade-finance products calibrated to a payments environment that now clears same-day across most of the region.

What comes next

The next test of bankability is disclosure: whether SADC or its member-state central banks publish participation fee schedules, settlement volumes or default data for the RTGS network, information that would let banks, insurers and trade financiers price risk against the system rather than around it.

Until that data exists, the safer capital-allocation posture is to treat SADC-RTGS as a credible but under-documented utility, useful as a qualitative signal of reduced settlement risk, but not yet a system with enough public disclosure to underwrite against directly.
