AML & Travel Rule
Suspicious Activity Report (SAR)
US terminology for the mandatory AML report — equivalent to the EU STR.
Definition
SAR is the US terminology for the AML report; STR is the EU equivalent. Both are mandatory filings to the relevant FIU when transactions raise AML concerns. US SARs go to FinCEN; UK SARs go to NCA; EU STRs go to the home-state FIU.
