Suspicious Transaction Report

Definition

A suspicious transaction report (STR) is a formal document submitted by a financial institution or digital asset service provider to a financial intelligence unit when they suspect a transaction may be related to illicit activities. These activities include money laundering, terrorist financing, or other financial crimes. The report details the nature of the transaction, the parties involved, and the reasons for suspicion. STRs are a vital tool in global efforts to combat financial crime and uphold regulatory compliance.
