In 2025, Africans processed $1.4 trillion through mobile money.
Not banks. Not cards. Phones.
That number makes Sub-Saharan Africa responsible for 70% of all mobile money transaction value on earth — more than Europe, North America, and Asia combined. Africa built the world’s most powerful informal payment system on infrastructure that didn’t exist 20 years ago.
But here’s what the headline hides.
The System Is Bigger Than Its Users
Africa holds more than half of the world’s 2.3 billion registered mobile money accounts.
The majority sit idle.
The GSMA’s 2026 State of the Industry report flags account inactivity as the defining challenge of the moment — a continent with unmatched infrastructure running far below its registered capacity. The rails exist. The trains aren’t full.
Three reasons explain why.
Fees. Governments across the continent introduced mobile money transaction levies that made digital payments more expensive than cash. In Malawi, public pressure eventually forced Airtel Money and TNM Mpamba to scrap some charges — but every new tax on a mobile transaction hands a user a reason to go back to physical notes. The governments most vocal about building cashless economies kept taxing the tool doing it.
Trust. In rural markets, money you can hold still feels safer than money on a screen. Financial literacy hasn’t kept pace with financial access.
Habit. Mobile money onboarding is easy. Sustained use requires a reason. Where merchants don’t accept it, users don’t need it.
Malawi’s Number Is the One That Should Surprise You
In 2015, Malawi had 2 million mobile money subscribers.
By 2023 that figure had reached 12 million — in a country of 21 million people.
A 500% increase in eight years. Two operators: Airtel Money and TNM Mpamba. No major bank expansion. No new branches. Just a SIM card and a USSD code.
That is the leapfrog story in its purest form. A country with one of the lowest banking penetration rates in the region built a functional digital payments layer before it built the infrastructure to support traditional finance.
The problem — and the opportunity — is that 12 million subscribers is not 12 million active users. Malawi mirrors the continental pattern exactly: registered far outpaces active. The infrastructure is there. The behaviour hasn’t caught up.
Kenya Solved This. The Rest of Africa Is Still Figuring It Out.
Kenya now holds 24.7% of Africa’s entire mobile money market — built on a single product from a single operator. M-Pesa commands 89% of Kenya’s domestic mobile money market.
How? It didn’t stay a payment tool. It became an ecosystem. Bill payments. Savings. Credit. Insurance. Business accounts. Once money lived on the phone for everything, using it for anything became default behaviour.
Companies like Tala built entire lending businesses on top of that transaction data — extending credit to millions of Kenyans who had never qualified for a bank loan, underwritten entirely by their M-Pesa history. No collateral. No branch visit. Just a record of how reliably someone moved money on their phone.
That model is replicable across every African market with mobile money infrastructure. Most haven’t done it yet.
The Three Moves That Separate Builders From Bystanders
Cash-only is a market size decision. In Malawi, Airtel Money and TNM Mpamba between them reach more people than every bank branch combined. A business that only takes cash has already chosen a smaller customer base. That choice gets more expensive every year.
Transaction data is the new collateral. Every mobile payment a customer makes is an underwriting signal. The businesses building credit, insurance, and savings products on top of mobile money rails are accessing a customer segment that formal finance has ignored for six decades. The data already exists. Most businesses aren’t using it.
The merchant side unlocks the consumer side. Users go active when they have somewhere to spend. The businesses making it frictionless for small traders — market vendors, salon owners, hardware stores — to accept digital payments are the ones that convert registered accounts into active ones. And they sit on every transaction that follows.
The $1.4 trillion is not the ceiling.
It is what Africa moved with the majority of its registered accounts sitting idle.
Unlock those accounts and you’re not looking at growth. You’re looking at a different continent.
