West Africa’s Mobile Money Giants Lose Cash Cow To Strict Fee Cap They Can’t Fight

Banks, fintechs and mobile money operators across West Africa will be forced to route all interoperable electronic money transfers through a single central bank platform from November 2, and they will be allowed to charge no more than 0.8% for transfers above a daily threshold of CFA francs 8 K (~USD 13.70).

The rules, published by the Central Bank of West African States (BCEAO) on October 2, mark the most aggressive intervention yet in a mobile money market that processed USD 498 B in transactions across West Africa in 2025, according to GSMA data. They represent a direct challenge to the business models of dominant operators such as Orange Money and Wave, which built their franchises on closed networks and transfer fees of around 1% or more.

The BCEAO, which oversees monetary policy for the eight-nation West African Economic and Monetary Union (WAEMU), had initially launched the platform, known as PI-SPI, on September 30, 2025, with free person-to-person transfers as its flagship selling point. One year later, that promise has been revised. Transfers of CFA francs 8 K or less, cumulated per day per user per participant, remain free. Above that, providers may charge up to 0.8% before tax. Receiving money is free without limit.

The central bank says the threshold keeps about 75% of electronic money transactions in the union free of charge. The cumulative nature of the cap is significant. Users cannot split a CFA franc 20 K transfer into three smaller ones to avoid fees. The daily total is tracked across all operations with the same institution.

“The logic of the reform is to protect small users while allowing providers to sustain the infrastructure,” said Tossouve Renaude Martinie, a payments specialist working across banking and mobile money in the region. “PI-SPI is not just a means of moving money. It is a public rail that the private sector must now build on.”

The pricing shift is accompanied by a regulatory mandate. From November 2, all interoperable electronic money transactions within WAEMU must transit through PI-SPI. Cross-border transfers within the union will follow the same pricing rules from June 1, 2027. The platform currently connects 175 institutions and reaches more than 38 million people, according to the BCEAO.

Wave, one of the region’s largest mobile money operators with more than 23 million monthly active users, joined PI-SPI on the September 30 regulatory deadline after a year of absence. The company built its success on a flat 1% transfer fee, and its delayed participation underscored the tension between its low-cost model and a free interoperability rail that could cannibalise its revenue.

Industry analysts expect operators to shift their monetisation strategies toward merchant payments, QR code services and business payment APIs. Ecobank, Standard Chartered, Orange, MTN and TouchPoint have already positioned themselves on the 24 certified business APIs that PI-SPI now offers.

“The real challenge is not connection. It is turning this infrastructure into daily usage,” said Aïssatou Ami Touré, managing director of TouchPoint Financial Services Senegal.

The rules leave several operational questions unanswered, including how providers must calculate fees on the transaction that takes a customer above the daily threshold.

The BCEAO has not specified whether the fee applies to the entire amount or only the portion exceeding CFA francs 8 K. For now, the central bank has drawn a clear line.
