On July 14, 2026, the National Banking and Securities Commission (Comisión Nacional Bancaria y de Valores) published a resolution modifying the general provisions applicable to credit institutions in Mexico's Official Journal (Diario Oficial de la Federación). The resolution harmonises the regulatory framework following amendments issued by Mexico's central bank, Banco de México, and the Ministry of Finance and Public Credit (Secretaría de Hacienda y Crédito Público). On June 17, 2026, Banco de México introduced a new operational tier called "Level 2 Bis" in the classification of sight deposit accounts through Circular 11/2026, which modified Circular 3/2012. The resolution updates general provisions to accommodate this new account classification alongside existing Levels 1, 2, 3, and 4. Key amendments include: revised customer identification requirements for presential and non-presential account opening across all account levels; updated provisions for electronic banking contracting; introduction of "Proof of Life" requirements—technical tests using algorithms to verify biometric characteristics and confirm a living subject is present during account opening procedures; establishment of biometric information databases for customer identity verification; and modified requirements for remote account opening for Level 2 Bis and Level 4 accounts, as well as consumer and commercial credit contracts. The resolution also repeals Article 316 Bis 9 and Annex 63 from the existing general provisions. Credit institutions must notify the Commission within 20 business days of implementing biometric verification systems. The resolution entered into force on July 15, 2026, the day following publication. These amendments strengthen regulatory coherence and provide legal certainty to credit institutions and their customers.
