New anti-money laundering rules from Mexico's finance ministry will require risk-based customer classification, beneficial ownership identification, and automated monitoring for all virtual asset transactions. The regulations classify virtual asset transactions as “vulnerable activities,” a legal designation that triggers a cascade of compliance obligations for anyone facilitating them. Digital asset service providers will also need to update and submit their internal policy manuals by the March 2027 deadline. Non-financial entities engaged in activities like virtual asset exchange and custody are required to register with the SAT (Tax Administration Service) and comply with AML responsibilities. The March 2027 compliance deadline allows market players approximately seven months to adjust their policies and operational systems.
