PAPSS vs Stablecoin Rails: Which One Settles African Cross-Border Trade?

When an African business needs to pay a supplier, the rail it picks decides whether the money clears in seconds or in days — and whether it touches a scarce U.S. dollar at all. Two new options now sit alongside the old correspondent-banking route: PAPSS, an African clearing system that settles trade between African countries in local currency in about 12 seconds, and stablecoin rails, which settle in Treasury-backed digital dollars for trade with anyone, anywhere. They are not competitors so much as answers to two different halves of the same dollar problem — and the split is lopsided, because intra-African exports were just 14.9% of the continent's total exports in 2023 (Afreximbank, 2025), so most trade still needs a dollar rail PAPSS cannot provide.

This is the decision-grade comparison: what each rail is, where it fits, and which one your business should use for a given payment. It sits inside our wider explainer on why dollars are scarce across Africa and the rails businesses use to settle anyway. For the mechanism of how a digital dollar settles a deal without touching central-bank reserves, we hand that off to how stablecoins solve dollar shortages in Africa — this page is the comparison.

PAPSS vs stablecoins — what's the difference?

PAPSS settles trade between African countries in local currency through a central clearing system; stablecoin rails settle in digital dollars for trade with anyone, anywhere. They solve different halves of the dollar problem. PAPSS removes the dollar from intra-African payments so two African businesses can transact in their own currencies. A USD stablecoin — a Treasury-backed digital dollar held 1:1 against U.S. Treasuries and cash — does the opposite: it gives a business genuine dollar access to pay a supplier in China, India, or the UAE, without queuing at the central bank for physical dollars.

The distinction matters because most African trade is not intra-African. Intra-African exports were just 14.9% of the continent's total exports in 2023, according to the African Export-Import Bank's 2025 trade report. The other ~85% — the imports that actually drain dollar reserves — flows to suppliers outside the continent, where PAPSS cannot reach and a dollar rail is still required.

PAPSS vs SWIFT vs stablecoins (head-to-head)

All three move cross-border payments, but they differ on speed, currency, cost, reach, and how much they depend on the dollar. SWIFT is a messaging network that routes payments through a chain of correspondent banks, usually settling in dollars over several days. PAPSS adds instant net settlement in local African currencies, but only for trade between participating African states. Stablecoin rails settle directly in digital dollars in minutes, for global trade. Here is the comparison side by side.

Two figures anchor the cost row. Sub-Saharan Africa is the world's costliest region to move money — it cost 8.78% to send $200 as of Q1 2025, against a 6.49% global average, per the World Bank's Remittance Prices Worldwide data. On the slow end, only 24.7% of Sub-Saharan beneficiary-leg payments clear within an hour — the joint-slowest globally — according to the Financial Stability Board's 2024 cross-border payments KPIs.

What is PAPSS, and who owns it?

PAPSS — the Pan-African Payment and Settlement System — is an Afreximbank-backed clearing system that lets African businesses pay across borders in their local currencies instead of routing every transaction through the dollar. It was developed by the African Export-Import Bank (Afreximbank) in collaboration with the AfCFTA Secretariat, and launched for commercial use in January 2022, as the U.S. government's trade office documents — with the launch announced jointly by Afreximbank and the African Union. Afreximbank acts as the main settlement agent, providing settlement guarantees and overdraft facilities to participating central banks.

Mechanically, PAPSS connects the real-time gross settlement (RTGS) systems of individual African central banks and nets out the day's transactions before midnight, so banks settle a single balance rather than thousands of individual cross-currency transfers, per the same trade.gov briefing. The network has scaled quickly: PAPSS reported roughly 18 central banks, 158 commercial banks, and 14 payment switches connected as of late 2025, according to African Business, up from 15 central banks in March 2025, as FXC Intelligence reported. Treat the count as fast-moving — it changes most quarters as new banks go live.

Is PAPSS faster and cheaper than SWIFT?

Yes — PAPSS settles in seconds rather than days, and is designed to cut the cost of moving money across African borders. The system guarantees that a cross-border payment completes within a maximum of 120 seconds, and in practice intra-African payments have averaged about 12 seconds, according to the PAPSS CEO, as reported by Leadership in May 2025. Correspondent-bank SWIFT chains, by contrast, run 3 to 5 (up to 7) business days — the multi-bank routing, not the messaging, is what takes the time.

On cost, Afreximbank projects PAPSS will save African businesses more than US$5 billion in transaction costs each year once fully implemented, by removing the third-currency conversion and the correspondent banks that charge for it, per the U.S. trade office. The savings come from eliminating a structural detour: previously, two African banks settling a payment between two African currencies had to convert through a third currency — usually dollars or euros — via correspondent banks often located outside Africa.

Does PAPSS replace SWIFT?

Not entirely — PAPSS replaces the settlement leg for intra-African trade, but SWIFT messaging and dollar correspondent banking still handle the majority of trade that flows outside the continent. PAPSS only reaches participating AfCFTA member states, so it does nothing for a Nigerian importer paying a factory in Shenzhen or a Kenyan distributor paying a pharmaceutical supplier in Mumbai. Those payments still need a global rail and, almost always, dollars.

The scale of that gap is the whole point. With intra-African exports at just 14.9% of total African exports in 2023 (Afreximbank, 2025), the dollar-denominated inbound corridors — China, the EU, India, the UAE — dwarf the intra-African flows PAPSS is built to net. PAPSS is a genuine fix for one slice of the problem; it is not a replacement for the dollar rail that settles the rest.

Does PAPSS solve the dollar shortage?

Partly — PAPSS removes the dollar from intra-African trade, but it still relies on prefunded liquidity, and it does not give a business the dollars to pay a supplier in China or the UAE. For the trade it does cover, this is a real reduction in dollar demand: two African parties no longer need to find dollars to settle with each other. But participating banks still have to hold currency balances to make net settlement work, so dollars and other hard currencies do not disappear from the system — they move to the edges.

Afreximbank and PAPSS have been explicit about that edge. The reliance on external hard currencies for African foreign exchange "drains an estimated $5 billion annually in fees, delays, and opportunity costs," which is why PAPSS launched a separate African Currency Marketplace in June 2025 to let businesses swap African currencies directly without routing through dollars, according to the Afreximbank/PAPSS announcement. The takeaway for a treasury team: PAPSS lowers your dollar dependence inside Africa, but the moment your supplier sits outside the continent, you are back to sourcing dollars — and back in the queue this whole pillar exists to explain in why USD is scarce in Africa.

Country-pair trade — where each rail fits

The rail you need depends on where your counterparty sits. Intra-African flows are PAPSS territory; the large inbound corridors from outside the continent are dollar territory, where a stablecoin rail competes directly with slow, expensive correspondent banking. The table below shows representative inbound, dollar-denominated corridors — the import bills that generate the dollar demand PAPSS cannot meet — alongside where each rail fits.

China-to-Nigeria two-way trade reached $21.9bn in 2024, and China-to-Egypt $17.4bn, per SAIS-CARI's China-Africa trade data. China-to-Ghana hit a record $11.84bn in 2024 (SAIS-CARI), India-to-Kenya two-way trade was $3.45bn in FY2024-25 (India's Ministry of Commerce, via DD News), and UAE-to-Nigeria non-oil trade set a record $4.3bn in 2024, up 55%, as Punch reported. Every one of those corridors settles in dollars, far from any African clearing system — which is exactly where a digital-dollar rail does its work. (Further reading: how that settlement works in practice for a single market in our Nigeria stablecoin guide.)

PAPSS vs stablecoins — which should your business use?

Use PAPSS for payments to other African countries in local currency; use a USD stablecoin when you need to pay a global supplier in dollars without joining the FX queue. Many businesses use both, because most run a mix of intra-African and inbound-global payments. The decision is not ideological — it is a routing question that turns on where the counterparty sits and what currency the deal is priced in.

A simple way to decide:

• Paying a supplier in another African country, in their currency? PAPSS is the cleaner fit — near-instant, local-currency, and it keeps the dollar out of the transaction entirely.
• Paying a supplier outside Africa, priced in dollars? A USD stablecoin settles in minutes without depleting central-bank reserves, where correspondent banking would take days and cost the most of any region.
• Running both? Use each rail for what it does best. PAPSS for the regional leg, a regulated dollar rail for the global leg.

And for how digital-dollar settlement stacks up against the correspondent-banking route specifically, our live comparison covers stablecoin settlement versus SWIFT. One regulatory note: these are settlement rails, not speculative crypto — regulated stablecoins like USDC and USDT hold a 1:1 dollar peg backed by U.S. Treasuries and cash, and this guide describes why businesses use them, not advice on navigating any country's exchange-control rules.

Common questions

Is PAPSS faster than SWIFT?
Yes. PAPSS settles in seconds — a maximum of 120 seconds by design, averaging about 12 seconds in practice (PAPSS CEO, May 2025) — versus 3 to 5 (up to 7) business days for a correspondent-bank SWIFT chain.

Who owns PAPSS?
PAPSS was developed by Afreximbank in collaboration with the AfCFTA Secretariat — its January 2022 launch was announced jointly with the African Union — and Afreximbank acts as its main settlement agent (trade.gov).

How many countries use PAPSS?
Roughly 18 central banks and 158 commercial banks across the AfCFTA region were connected as of late 2025 (African Business). The count rises most quarters as new banks go live, so check the current figure before relying on it.

Can stablecoins and PAPSS be used together?
Yes, and many businesses do. PAPSS handles the intra-African leg in local currency; a USD stablecoin handles the dollar leg for suppliers outside the continent. They cover different corridors, so they complement rather than compete.

Settle global trade in dollars with Artoh

Where PAPSS reaches — payments between African countries in local currency — it is a genuine upgrade on the old correspondent-banking detour. But the larger share of African trade flows outside the continent, to dollar-priced suppliers in China, India, the UAE, and Europe, where PAPSS cannot help and the FX queue still binds. That is the gap Artoh is built to close: compliant USD settlement through regulated, Treasury-backed stablecoins, so a business can pay a global supplier in minutes without waiting on a central-bank dollar allocation.

If you run a mix of intra-African and global supplier payments — and most importers do — the practical answer is rarely one rail. It is PAPSS for the regional leg and a reliable dollar rail for everything else. If dollar access is what is blocking your payments, let's talk.
