Mobile Money Fragmentation: Walled Gardens Are Preventing a Global Financial Inclusion Breakthrough
Problem Definition
Mobile money is one of the most powerful financial inclusion tools ever invented — but its transformative potential is being strangled by fragmentation. The 315 mobile money services operating globally are largely walled gardens: incompatible systems that cannot easily transfer value to each other.
A smallholder farmer in Tanzania can receive payment via M-Pesa but cannot directly pay a supplier in Uganda using Airtel Money or repay a loan from a Rwandan microfinance institution.
This fragmentation forces users to cash out and re-deposit — incurring fees, time costs, and physical security risks — and prevents the development of the cross-border digital economy that would most benefit low-income populations.
Root Causes
Mobile money providers have commercial incentives to maintain walled gardens — interoperability reduces switching costs and competitive advantage
Regulatory frameworks are national while the most transformative use cases (remittances, trade) are cross-border
Technical standards for interoperability are fragmented across ISO 20022, GSMA open API standards, and proprietary protocols
AML/KYC requirements create compliance friction at borders that raises cost of cross-system transactions
Central banks and regulators in developing countries often lack technical capacity to design and enforce interoperability mandates
