The Central Bank of West African States (BCEAO) has quietly pushed back a critical deadline for fintechs and banks to fully integrate into its flagship interoperable payments system, granting the region’s dominant mobile money operators a few more months of breathing room but holding firm on the end of the year as the final backstop.
In a brief communiqué issued from its Dakar headquarters on 25 June, the central bank for the eight-nation West African Economic and Monetary Union (UEMOA) announced a formal extension to the timeline for connecting to the Interoperable Instant Payment System Platform (PI-SPI).
The original deadline of 30 June 2026, widely viewed as a hard ultimatum for the bloc’s largest fintechs to dismantle their closed-loop networks, has been moved to 30 September 2026 for banks, electronic money institutions (EMEs), and payment establishments. For microfinance institutions supervised by the UMOA Banking Commission, a longer leash has been granted, with a new deadline of 30 June 2027.
The move offers a short reprieve in what has become a high-stakes infrastructure struggle between a determined regulator and an industry whose business models are built on proprietary rails.
The state of play
Launched on 30 September 2025, the PI-SPI was designed as the foundational layer for a unified financial market. It acts as a shared, neutral rail system that allows a user of one financial service to send money instantly — in under ten seconds — to a user of any other service, whether a traditional bank account or a mobile wallet from a competing telecom. The system mandates free person-to-person transfers, a regulatory choice aimed squarely at accelerating financial inclusion.
In its communiqué, the BCEAO stated that as of 24 June 2026, eighty institutions are now connected to the platform, serving several million users. A further 74 institutions are in a phase of real-world testing before a public launch. The central bank said the extension was granted to allow these establishments to complete integration “in the best conditions and to ensure a quality of service in line with the platform’s requirements.”
A market at a crossroads
The PI-SPI project is an intervention in one of the world’s most active mobile payments markets. In 2024, the UEMOA region processed 11 billion mobile money transactions worth roughly $267bn (160,415 billion CFA francs), a figure representing 119% of the union’s combined GDP. More money moves through mobile wallets in this bloc than the entire formal output of its economies.
But that liquidity flows largely within walled gardens. The rapid initial onboarding of 80 participants onto PI-SPI obscures a glaring absence: the two largest transaction processors by value, Wave and Orange Money, have moved cautiously.
For Wave, the US-backed fintech that launched in Senegal in 2018, the reluctance is an existential calculus. Its aggressive growth — capturing a 38.2% share of the union-wide market by transaction value in 2024, up four percentage points in a single year — was built on a flat-fee, closed-loop network designed to be cheaper and faster than incumbent telecom operators. Full interoperability through PI-SPI offers a technical gateway to bank deposits, but it also allows every competing bank, microfinance app, and telecom to replicate Wave’s core proposition: fast, cheap transfers. Joining the central bank’s network cedes control and commoditises the operational moat Wave spent six years building.
Orange Money, the mobile financial services arm of the French telecom group, saw its value share slip to 41.3% in 2024. If current trajectories hold, Wave will surpass it within two years. Orange’s positioning on interoperability has already drawn political scrutiny. When the central bank required PI-SPI transfers to be free, Orange eliminated its standard transfer fees but introduced a 1% charge on cash withdrawals, capped at 5,000 CFA francs. This effectively shifts the cost burden from the sender to the recipient. BCEAO data shows the “net digitalisation ratio” in the region is just 7.52% — meaning for every 100 CFA francs deposited into a mobile wallet, 92.48 francs are eventually cashed out. In a market where users still treat wallets as transit points rather than stores of value, a 1% withdrawal fee functions as a tax on the dominant use case.
The underlying commercial tension
The new 30 September deadline acknowledges the complexity of integrating these behemoths without triggering service disruption. The PI-SPI’s architecture is not merely a technical upgrade; it is a direct challenge to the profitability model of closed-loop mobile money, where margins are derived from controlling the entire chain from cash-in to cash-out.
While the volume of person-to-person transfers remains high, the average value dropped 9% to roughly $30 in 2024, indicating mobile money is increasingly used for routine, small-value transactions where a withdrawal tax is acutely felt. Simultaneously, traditional commercial banks are aggressively entering the space. Their share of total transaction volume in UEMOA rose from 13% to 18% in 2024, aided by a growing number of fintech partnerships. The PI-SPI, by providing neutral infrastructure, accelerates the ability of these banks to reach mobile wallet users directly, bypassing the telecom-operator gatekeepers.
The merchant payments segment is also scaling rapidly, jumping from 3.3% of all payment volume in 2020 to 23.3% in 2024, driven by a doubling of registered merchant points to 3.7 million. An interoperable network makes this growth more fluid and harder for any single player to monopolise.
By shifting the deadline by three months for the major players and extending the timeline for microfinance institutions into mid-2027, the BCEAO has chosen a pragmatic path, avoiding a regulatory cliff that could have fragmented the market in the short term. The central bank’s language remains firm in its strategic intent, framing PI-SPI as a reaffirmation of its commitment to “useful innovation, serving financial inclusion and the modernisation of payment infrastructure.”
The 30 September deadline offers a brief window to defaulting firms to finalise technical integrations and adjust commercial strategies to an environment where the transfer itself is no longer a source of competitive advantage. The clock is no longer counting down to a June ultimatum, but the end of September represents a hard stop on an era of proprietary dominance in the West African payments landscape.
