BREAKING: Dutch central bank fines Modulr Finance over weak customer monitoring - AML Intelligence

Dutch financial regulator De Nederlandsche Bank (DNB) has imposed a fine on payments firm Modulr Finance over shortcomings in its customer monitoring, according to AML Intelligence. The action centres on anti-money-laundering controls — specifically, the systems firms use to keep track of who their customers are and flag unusual activity.

The case is a reminder that payment institutions, not just traditional banks, sit squarely within the AML perimeter in the Netherlands and across the EU. As licensed payment firms scale, onboarding volumes and transaction flows can outpace the compliance frameworks built to police them. Regulators have repeatedly stressed that growth does not dilute monitoring obligations.

For markets, the relevance is twofold. First, it adds to a steady drumbeat of European enforcement against payment and fintech firms, reinforcing expectations of tougher supervisory scrutiny. Second, it highlights compliance costs as a structural factor for the sector — spending that can weigh on margins but also serves as a competitive moat for well-controlled operators. What to watch: whether Modulr appeals, how DNB frames the remediation requirements, and whether other supervisors follow with similar actions.
