Africa’s vast mobile ecosystem is emerging as a critical battleground in the fight against financial crime, with more than 1.1 billion mobile subscriptions across the continent providing criminals with an increasingly accessible channel for moving money and executing fraud.

The scale of mobile connectivity is creating both opportunities and compliance risks for financial institutions, telecommunications operators, mobile money providers and law enforcement agencies.

INTERPOL has highlighted the size of Africa’s mobile market alongside the growing volume of money moving through mobile channels, underscoring the challenge facing authorities as financial crime increasingly shifts towards digital platforms.

The development comes against a broader rise in cyber-enabled financial crime across Africa. INTERPOL’s Africa Cyberthreat Assessment has identified online scams, phishing, business email compromise, ransomware and digital sextortion among the major threats confronting the region. Online fraud accounted for more than 30 per cent of reported crimes in parts of Western and Eastern Africa in the assessment.

The growing use of mobile money and digital financial services has also expanded the number of channels available to criminal networks. Fraud proceeds can be moved rapidly between mobile wallets, bank accounts, digital assets and other payment platforms, creating complex trails that can cross several jurisdictions.

INTERPOL’s enforcement operations have demonstrated the scale of the problem. During Operation Serengeti in 2024, authorities identified more than 35,000 victims linked to cases involving nearly $193 million in financial losses worldwide. In Kenya, investigators uncovered an online credit card fraud case involving losses of about $8.6 million.

For financial institutions and mobile money operators, the expanding digital payment ecosystem increases the importance of customer due diligence, transaction monitoring, suspicious transaction reporting and effective controls against account takeover, identity fraud and money laundering.

The compliance challenge is particularly significant because mobile connections do not necessarily represent unique individuals. A single person can hold multiple SIM cards or subscriptions, while shared devices and accounts can further complicate customer identification and transaction monitoring. Historical GSMA data has similarly distinguished mobile connections from unique subscribers, noting that one subscriber can have multiple connections.

The result is a regulatory environment in which telecommunications, financial crime compliance and cybersecurity are becoming increasingly interconnected.

As mobile money continues to expand across Africa, regulators and enforcement agencies are likely to place greater scrutiny on the movement of funds across mobile wallets, banks, cryptocurrency platforms and informal financial networks.

For compliance teams, the message is clear. Mobile connectivity is no longer simply a telecommunications issue. It has become a central component of the continent’s financial crime risk landscape.
