How PAPSS Works: Inside African Cross-Border Payments
A Nigerian importer wants to pay a Ghanaian supplier 50,000 Cedis. In 2021, that instruction would bounce through London, convert to dollars twice, and take up to five business days. Today, the Pan-African Payment and Settlement System (PAPSS) can clear that same payment in local currencies within hours. Understanding how PAPSS works for African cross-border payments means looking past the press releases and into the actual plumbing: participating banks, net settlement windows, and Afreximbank’s role as the clearing counterparty. Here is what actually happens between “send” and “received.”
What PAPSS Is and Why It Matters for Intra-African Trade
PAPSS is a cross-border payment infrastructure built by Afreximbank in partnership with the AfCFTA Secretariat, designed to let businesses settle trade payments in African currencies without routing through European or American correspondent banks. It went live commercially in 2022 after a pilot phase that began with the West African Monetary Zone. The system connects participating commercial banks across member states, processes payment instructions in near real time, and settles the net obligations between central banks through Afreximbank accounts.
The reason this matters is structural. Intra-African trade has hovered around 15% of total African trade for years, far below the 60% regional trade share in Europe. Payment friction is not the only reason, but it is a big one. When a Lagos importer can pay Accra only by converting Naira to USD, moving the dollars through a London correspondent, then converting USD to Cedis, the cost stacks: two FX spreads, SWIFT fees, lifting charges, and three to five days of settlement risk. PAPSS removes the hard-currency detour, at least in theory.
The institutions behind the rails
Three layers of institutions sit inside PAPSS. Participating commercial banks in each country connect directly to the PAPSS platform and submit payment instructions on behalf of their customers. Central banks in participating countries hold settlement accounts at Afreximbank, which acts as the clearing house and settlement agent. The AfCFTA Secretariat provides the trade-policy framework that gives PAPSS its regulatory legitimacy, while Afreximbank provides the technical infrastructure and the settlement assurance. Think of PAPSS as the messaging and validation layer, while Afreximbank is the trusted counterparty that makes sure everyone actually gets paid.
The Pre-PAPSS Problem: Why Naira-to-Cedi Payments Used to Take 3 to 5 Days
Before PAPSS, a Naira-to-Cedi payment had no direct clearing rail. The Nigerian importer’s bank would initiate a SWIFT message to a correspondent bank, typically in London or New York. That correspondent would convert the Naira to USD (or EUR), debit the Nigerian bank’s nostro account, and forward the USD to a Ghanaian bank’s correspondent. The Ghanaian bank would then convert the USD to Cedis and credit the supplier’s account. Each hop added time, cost, and risk.
The Verto payment crisis analysis we covered at Dotifi Digital lays out the numbers bluntly: a $10,000 cross-border transfer between African countries through traditional banking can carry $430 to $650 in combined costs, with FX spreads on exotic pairs running 3 to 7%. The settlement timeline regularly extends to five to seven business days. For a supplier in Accra waiting on payment before releasing goods, that is not an inconvenience. It is a working-capital problem that makes trade within Africa more expensive than trade with Europe.
Why the correspondent route is structurally slow
The delays are not just technology lag. They are architectural. SWIFT is a messaging system, not a settlement system. The actual money movement depends on correspondent banks having sufficient nostro liquidity in the right currency, at the right time, across time zones. AML and compliance desks at each correspondent manually review flagged transactions. The Central Bank of Nigeria applies its own FX controls before releasing funds. The Bank of Ghana applies its own checks on the receiving end. Each checkpoint is reasonable in isolation, but the serial nature of the chain means delays compound rather than overlap.
Step-by-Step: How a Naira-to-Cedi Payment Clears on PAPSS
Here is the concrete walkthrough. A Nigerian importer, let us call her Ada, needs to pay 50,000 GHS to her Ghanaian supplier, Kwesi. Both banks, Access Bank Nigeria and Stanbic Ghana, are PAPSS participants. Their respective central banks, the CBN and the Bank of Ghana, hold settlement accounts at Afreximbank. Here is what happens in sequence.
Step 1: Payment initiation (Seconds)
Ada logs into her corporate banking portal at Access Bank Nigeria and enters a payment instruction: beneficiary Kwesi, amount 50,000 GHS, purpose invoice #GH-2026-014. Access Bank validates Ada’s account balance and KYC status, then submits the instruction to PAPSS via the platform’s API. This is a near-instant step, comparable to initiating a domestic transfer.
Step 2: Validation and routing (Minutes)
PAPSS receives the instruction and performs validation checks. It confirms that Access Bank Nigeria is an active participant, that Stanbic Ghana is the receiving bank and is also connected, and that both central banks have live settlement accounts. PAPSS checks AML and sanctions screening at the platform level. If the payment passes, PAPSS routes the instruction to Stanbic Ghana for processing. This routing bypasses SWIFT entirely. The message travels through PAPSS’s own secure messaging infrastructure, not through the SWIFT network.
Step 3: Beneficiary bank processing (Minutes to hours)
Stanbic Ghana receives the instruction, verifies Kwesi’s account, and applies its own compliance checks. If Kwesi’s account details match and there are no flags, Stanbic credits Kwesi’s account in Cedis. The supplier sees the funds arrive. In many cases this happens within minutes of initiation, though beneficiary bank processing times vary depending on internal workflows.
Step 4: Net settlement at the central bank level (End of cycle)
Here is where the plumbing differs from what most people expect. Kwesi may already see the Cedis in his account, but the actual money movement between banks has not happened yet. PAPSS does not settle each payment individually. It accumulates all instructions between participating banks over a settlement cycle, nets the bilateral positions, and then settles the net obligations through the central banks’ accounts at Afreximbank. This is the net settlement model, and it is the core innovation.
The Net Settlement Model Explained (Without Jargon)
Net settlement means PAPSS does not move the full amount of every individual transaction. Instead, it adds up all the payments flowing in each direction between two banks (or two countries) during a settlement window, calculates the net difference, and moves only that difference. Think of it as running a tab at a bar. You do not pay for each drink as it arrives. You settle the total at the end of the night.
In our example, imagine that during the same settlement window, Access Bank Nigeria’s customers sent 50,000 GHS to Ghana, and Stanbic Ghana’s customers sent 20,000 GHS worth of Naira payments back to Nigeria. The gross flow in both directions is 70,000 GHS. But the net obligation is only 30,000 GHS, owed by the Nigerian side to the Ghanaian side. PAPSS calculates that net position and settles it through the CBN and Bank of Ghana accounts at Afreximbank.
Why netting matters for liquidity
Netting reduces the amount of actual currency that needs to move between central banks. If every payment settled gross, the CBN would need to hold enough Cedis (or the equivalent in a settlement currency) to cover every single outgoing payment in real time. With net settlement, the CBN only needs to cover the net outflow at the end of the cycle. This is critical because African central banks often have limited hard-currency reserves. Netting lets the system operate with far less liquidity than gross settlement would require.
The Afreximbank settlement layer
Afreximbank sits at the center as the settlement agent. Each participating central bank maintains a settlement account with Afreximbank. At the end of a settlement cycle, PAPSS sends the net positions to Afreximbank, which debits and credits the central bank accounts accordingly. If the CBN owes the Bank of Ghana a net amount, Afreximbank debits the CBN’s account and credits the Bank of Ghana’s account. Afreximbank effectively guarantees the settlement, which means participating banks can credit their customers before the gross funds have moved, trusting that the net settlement will complete at the end of the cycle.
This is the same trust model that underpins domestic real-time gross settlement systems, but applied across borders and denominated in local currencies rather than a single national currency. The key difference is that Afreximbank absorbs the settlement risk between central banks, which is what makes cross-border local-currency clearing possible in the first place.
PAPSS vs. Correspondent Banking vs. Stablecoin Corridors
PAPSS is not the only alternative to legacy correspondent banking for African cross-border payments. Stablecoin corridors, powered by USDC and USDT on chains like Tron and Solana, have grown aggressively as a parallel settlement layer. The Nigerian founder tackling the UK-to-Nigeria remittance corridor we profiled at Dotifi Digital built SendOva precisely because the existing options were too expensive and too slow. Each approach trades off differently on speed, cost, regulatory certainty, and FX risk.
| Feature | PAPSS | Correspondent Banking (SWIFT) | Stablecoin Corridors |
|---|---|---|---|
| Settlement time | Minutes to hours (credit), end-of-cycle (net settlement) | 3 to 5 business days | Seconds to minutes (onchain confirmation) |
| Currency | Local African currencies (NGN, GHS, KES, etc.) | USD or EUR intermediary | USD-pegged stablecoins (USDC, USDT) |
| FX conversion | Once, at local rate via participating banks | Twice (NGN to USD, USD to GHS) | Once (stablecoin to local currency via exchange or P2P) |
| Typical cost on $10,000 | Estimated 1 to 2.5% (varies by corridor) | 4.3 to 6.5% ($430 to $650) | 0.5 to 2% (chain fees + exchange spread) |
| Regulatory status | Central bank-backed, Afreximbank settlement | Mature, globally regulated | Evolving; varies by jurisdiction |
| Accessibility | Requires PAPSS-participating bank in both countries | Available wherever SWIFT reaches | Requires crypto wallet, internet, on/off-ramp |
| FX risk | borne by participating banks; settled in local currency | Borne by sender and receiver (double conversion) | Borne by whoever holds the stablecoin between send and convert |
| Counterparty risk | Afreximbank (sovereign-backed) | Correspondent bank (commercial) | Stablecoin issuer and smart contract |
The stablecoin column is worth attention. Global stablecoin transaction value reached an estimated $33 trillion in 2025, as we noted in our coverage of Revolut’s stablecoin payment surge. For corridors where PAPSS is not yet live, stablecoins fill the gap with near-instant settlement and low fees. But they introduce their own risks: custody, regulatory uncertainty, and the FX risk of holding a dollar-pegged asset while waiting to convert into local currency. PAPSS trades some speed for regulatory certainty and local-currency settlement, which matters for businesses that need to pay invoices in Cedis, not in synthetic dollars.
Where PAPSS Still Breaks Down in 2026
PAPSS is a meaningful improvement over correspondent banking, but it is not a silver bullet. Several structural constraints limit its real-world impact in 2026, and understanding these is essential for anyone evaluating whether PAPSS will actually move the needle on intra-African trade.
Coverage gaps
PAPSS is only as useful as the number of participating banks and countries live on the system. While Afreximbank has signed up dozens of countries, the number of commercial banks actively routing live payments through PAPSS is smaller. A corridor only works if both the sender’s bank and the receiver’s bank are connected. If a Nigerian importer’s bank is on PAPSS but the Ghanaian supplier’s bank is not, the payment falls back to the old correspondent route. Coverage is uneven across the continent, with West Africa better represented than East or Central Africa.
Central bank liquidity and FX controls
The net settlement model assumes that central banks can and will honor their net obligations at the end of each settlement cycle. If the CBN restricts FX access or delays settlement due to reserve constraints, the entire corridor backs up. As Verto’s CEO Ola Oyetayo observed in our payment crisis analysis, if central banks backing PAPSS do not have the reserves to guarantee settlement at the back end, PAPSS risks shifting friction from the commercial bank level to central bank settlement gridlock. The system is only as fast as its slowest central bank.
FX rate determination
PAPSS settles in local currencies, but someone still has to determine the exchange rate between Naira and Cedis. If the rate is set administratively rather than by market demand, the effective cost of the payment may be higher than the headline fee suggests. A distorted official rate can mean the receiver gets fewer Cedis than they would on the parallel market, even if the transaction clears faster. This is the same problem that plagues traditional correspondent banking, just in a different form.
Onboarding friction for businesses
For a business to use PAPSS, its bank must be a participant and the business must be set up for cross-border payment origination through that bank’s PAPSS integration. Not all banks have exposed PAPSS functionality in their corporate banking portals. Some require manual instruction submission. For SMEs used to sending a quick mobile money transfer, the PAPSS onboarding process can feel bureaucratic, even if the settlement itself is fast once initiated.
What to Watch Next
PAPSS is at the stage where the architecture is sound but the coverage, liquidity, and operational maturity are still catching up. The next 12 to 18 months will tell whether it becomes the default intra-African settlement rail or remains a useful but partial solution alongside stablecoin corridors and fintech platforms like Verto.
Watch for three signals. First, how many additional commercial banks go live on PAPSS in corridors beyond West Africa, particularly in East Africa where M-Pesa’s cross-border rails already dominate low-value transfers. Second, whether Afreximbank introduces intraday liquidity facilities to reduce settlement cycle delays for central banks with tight reserves. Third, whether PAPSS integrates with domestic instant payment systems like Nigeria’s NIBSS and Ghana’s GhIPSS to create a true end-to-end experience from mobile initiation to cross-border settlement.

Frequently Asked Questions
How does PAPSS settle payments between African countries?
PAPSS uses a net settlement model. Participating banks submit payment instructions through the PAPSS platform, and the system accumulates all bilateral flows during a settlement cycle. At the end of the cycle, PAPSS calculates the net obligation between each pair of central banks and settles through their accounts at Afreximbank, which acts as the clearing counterparty and settlement agent.
How long does a PAPSS payment take to clear?
The beneficiary can see funds credited within minutes to hours of the payment being initiated, but the actual interbank settlement happens at the end of the settlement cycle when net positions are calculated and moved through Afreximbank. This is faster than the 3 to 5 day correspondent banking route, though end-to-end speed depends on beneficiary bank processing and central bank liquidity.
What is the difference between PAPSS and correspondent banking?
Correspondent banking routes African cross-border payments through European or US banks, converting local currencies to USD or EUR twice, which adds FX spreads, SWIFT fees, and 3 to 5 days of delay. PAPSS settles directly in local African currencies between participating banks, with Afreximbank as the settlement agent, removing the hard-currency detour and reducing both cost and time.
Can any African business use PAPSS to make payments?
Only if the business banks with a commercial bank that is a PAPSS participant, and the receiving bank in the destination country is also connected. Coverage is still uneven across the continent, with West Africa better represented than other regions. If either bank is not on PAPSS, the payment falls back to the traditional correspondent banking route.
Does PAPSS eliminate foreign exchange risk?
PAPSS eliminates the double-conversion cost of routing through USD or EUR, but it does not eliminate FX risk entirely. The exchange rate between the two local currencies still applies, and if that rate is set administratively rather than by market demand, the effective cost may be higher than the headline fee suggests. The participating banks determine the rate at the point of payment.
