The Financial Crimes Enforcement Network (FinCEN) announced a multi-tiered, data-driven operation focused on more than 100 US money services businesses (MSBs) operating along the southwest border, examining them for potential non-compliance with regulations designed to detect money laundering and combat illicit finance. The operation has resulted in six notices of investigation, dozens of examination referrals to the Internal Revenue Service (IRS), and more than 50 compliance outreach letters. FinCEN positioned the initiative as enabled by technology modernisation efforts pushed by Treasury Secretary Bessent.
