The inclusion decade: how mobile money rewired African central banking

When M-Pesa launched in Kenya in 2007, the Central Bank of Kenya faced a choice that would echo across the continent: block a telecoms company from taking deposits, or write new rules for something that was not quite banking. It chose the latter, and African financial inclusion has never looked back.

Sub-Saharan Africa now accounts for the majority of global mobile money transaction value on industry association figures, and mobile money accounts outnumber bank accounts in many markets. Financial inclusion rates across the region have risen dramatically in fifteen years. Central banks have moved from reluctant permission to active dependence: government payments and emergency cash transfers routinely ride on mobile rails.

The regulatory architecture matured in three waves. First came e-money licensing, ring-fencing customer float in trust accounts at commercial banks. Second, interoperability initiatives connected wallets to each other and to banks. The third wave, under way now, is prudential: as mobile money balances reach macro-relevant scale, regulators are imposing capital, governance and consumer-protection requirements that look increasingly bank-like.

The tension of the next decade is concentration. In several markets a single operator processes a share of retail payments that would attract systemic-risk designation in any G20 economy — simultaneously the region's greatest inclusion success and its largest single point of failure.

What comes next is being layered on top: instant payment systems linking banks and wallets, open-finance frameworks giving customers rights over their data, and credit markets built on transaction histories. The lesson African regulators exported to the world stands: inclusion is not only a product of banking infrastructure — it is a product of regulatory imagination.
