Mexico’s Ministry of Finance and Public Credit (SHCP) has amended anti-money laundering rules to require full identity verification for every Bitcoin and crypto transfer in the country from March 1, 2027, marking the biggest expansion of Mexico’s digital-asset compliance regime since the 2018 Fintech Law. The updated General Rules to the Federal Anti-Money Laundering Law, released in early August 2026, treat virtual asset transactions as vulnerable activities, triggering mandatory customer risk classification, enhanced due diligence (extra checks for higher-risk clients), and identification of ultimate beneficial owners, or UBOs (people who ultimately own or control an entity), when they hold 25% or more of a transacting party. The framework also requires providers to file internal policy manuals by the March 2027 deadline, bring automated suspicious-transaction monitoring online by June 1, 2027, and prepare for full regulatory audits expected in 2028. It adds stricter rules on registration, traceability and custody, while removing the practical effect of the previous roughly $3,500 reporting threshold by requiring identification data on all transfers regardless of size. Non-financial entities involved in virtual asset exchange and custody must register with the SAT (Tax Administration Service) and meet AML obligations, leaving market participants about seven months to adjust their systems and policies.
