Unusual Activity

Overview

Unusual activity refers to customer behavior or transactions that deviate from established patterns and may indicate money laundering or fraud. Examples include sudden large transfers, transactions inconsistent with a customer’s profile, or dealings with high-risk jurisdictions.Regulators require institutions to detect, document, and investigate unusual activity as part of AML/CFT compliance.
Transaction monitoring systems use rules, TRIs, and machine learning to flag such activity in real time.While unusual activity does not always mean wrongdoing, it triggers further investigation and may lead to filing a Suspicious Activity Report (SAR). Proactive detection protects institutions against financial crime risks and regulatory penalties.
