A regional first
On 30 September 2025, the Banque Centrale des États de l'Afrique de l'Ouest (BCEAO) switched on PI-SPI — its Pan-African Instant Payment System. The launch made individual mobile money and bank transfers free and effectively instantaneous between all eight WAEMU member states.
This is the first time a major African central bank has mandated zero-fee cross-border individual transfers across an entire monetary union. Compare with the EAC corridors (see EAC page), where M-Pesa Global and MTN MoMo still apply domestic-tier fees, and with the Nigeria → Africa corridor (see Nigeria-Africa) which carries a roughly 3% fee.
Why WAEMU built PI-SPI
Before PI-SPI, sending money across the WAEMU zone was paradoxically more expensive than sending within a single country, despite the shared CFA franc and shared central bank. The eight national mobile money ecosystems operated as interoperability silos: a Wave Senegal user wanting to pay a Moov Money Burkina Faso recipient typically had to route through Western Union or a costly cross-border MoneyGram corridor at 3%-7% of the transfer amount.
BCEAO began designing PI-SPI in 2022 as a regional payment switch that would let licensed banks and PSPs (payment service providers) plug into a common ISO 20022-based rail. By the September 2025 launch, all eight national central banks had signed onto the technical and legal framework, and the major operators (Wave, Orange Money, MTN MoMo, Moov, Celtiis) had completed certification.
The technical architecture
PI-SPI is not a wallet — it is a payment switch operated by BCEAO that routes individual transactions in near real time between participating institutions. A Wave Senegal user initiating a transfer to a Moov Money Côte d'Ivoire recipient does not see PI-SPI directly; from their app, the experience is identical to a domestic Wave transfer. Under the hood, the message is routed through the BCEAO switch, validated against AML and limit rules, and credited to the destination wallet within seconds.
What is free, exactly
PI-SPI free transfers apply to:
- Individual (P2P) transfers between mobile money wallets in any of the 8 WAEMU countries
- Bank account ↔ wallet transfers within the same regional rail
- Most transfers up to roughly XOF 2,000,000 per transaction
What is not free:
- Merchant payments may still carry an interchange fee
- Business-to-business transfers above the regulatory threshold
- Withdrawals at agents (these stay on each country's national tariff)
The 8 WAEMU countries
Senegal, Côte d'Ivoire, Mali, Burkina Faso, Benin, Togo, Niger and Guinea-Bissau. All eight share the XOF (West African CFA franc) and the BCEAO as their central bank.
What it changes for users
A small business owner in Lomé can now receive a payment from a customer in Dakar without paying the 1-3% fee that previously applied to inter-state mobile money corridors. For diaspora flows that route through a WAEMU country first, PI-SPI removes the second hop fee.
What other African unions are watching
PI-SPI is being studied closely by the East African Community (EAC) and the Common Market for Eastern and Southern Africa (COMESA). The EAC has its own regional payment-system project under development, and observers from Kenya, Tanzania and Uganda attended BCEAO's launch sessions. A similar zero-fee mandate across the EAC would be more complex politically because the EAC currencies float independently — there is no shared monetary union equivalent — but the technical blueprint is portable.
