Financial crime and AML

Suspicious transaction report (STR)

A report an institution files with the national financial intelligence unit when it suspects that funds are the proceeds of crime or are linked to terrorist financing.

In plain English

When monitoring, a customer's behavior or other information gives reasonable grounds to suspect money laundering, terrorist financing or related crime, institutions are required to report to the financial intelligence unit (FIU). In some jurisdictions the same report is called a suspicious activity report (SAR). In the UAE, reports go to the UAE Financial Intelligence Unit.

Reports must usually be made promptly, must be of good quality, and must never be disclosed to the customer, because tipping off can be an offense. The FIU uses reports to build intelligence and may share them with law enforcement.

Why it matters to a board

Reporting is the most direct way an institution contributes to the fight against financial crime, and failing to report, or reporting late, can carry serious penalties. Boards should see reporting volumes, timeliness and quality indicators.

Common mistakes

  • Filing late.
  • Defensive reporting of everything, which buries real intelligence.
  • Thin narratives that give the FIU nothing to act on.
  • Tipping off the customer.
