Learn what’s changing for RDFIs, ODFIs, TPSs, and TPSPs—and how Unit21 empowers you to detect, monitor, and act on ACH fraud with confidence.
The NACHA 2026 Fraud Monitoring Rule expands compliance expectations across the ACH ecosystem—making proactive fraud monitoring mandatory for a wider group of institutions. Here’s what’s changing.
No. NACHA encourages risk-based monitoring, not individual screening. You must assess transaction patterns, velocity, and anomalies based on customer risk.
A Third-Party Sender submits ACH entries on behalf of an originator without a direct relationship with the ODFI. If your volume exceeds 6M annually, you must comply by March 2026.
Most customers deploy relevant NACHA-compliant detection rules in under one week, using pre-built templates and our no-code rule engine.
Not with Unit21. Our platform allows you to monitor both sending and receiving activities at the entity level in one unified system. You can even flag when a customer is both originator and receiver — a common indicator of money mule behavior
Our Customer Risk Rating (CRR) allows you to segment originators based on ACH volume, behavior patterns, industry, and historical fraud risk. You can then plug those scores directly into your monitoring rules to scale compliance without over-alerting.
Institutions that fail to implement proper monitoring may face regulatory scrutiny, increased fraud losses, and potential removal from the ACH network. Proactive compliance not only protects your customers — it protects your institution’s reputation and operational resilience.
NACHA specifically highlights threats like payroll redirection, vendor impersonation, account takeovers (ATO), and synthetic identity fraud. Your monitoring should focus on behavioral anomalies, first-time ACH activity, name mismatches, and changes in transaction frequency or counterparties.
