The Financial Crimes Enforcement Network has issued a notice urging financial institutions in and around cities hosting the 2026 FIFA World Cup to heighten monitoring for sex and labor trafficking. FinCEN said the tournament is expected to draw millions of domestic and foreign visitors, creating conditions that traffickers may exploit, and asked firms to detect and report suspicious activity linked to potential human trafficking. The notice urges institutions to notify law enforcement through the National Human Trafficking Hotline and to file Suspicious Activity Reports as soon as possible regardless of threshold. It also encourages voluntary information sharing, including cross-border sharing where appropriate, to help identify and prevent money laundering or possible terrorist activity tied to human trafficking. FinCEN said customer-facing staff should be alert to transactional and behavioral red flags, including unusually large travel-related transactions, cash deposits followed by transfers to other accounts, payments through peer-to-peer transfers, credit cards, digital assets or prepaid access cards, exploitative labor patterns at seemingly legitimate businesses, withheld wages, transfers from a victim's account to a trafficker's account, and limited spending on essential needs.
