In late July 2026, customers of Mexican banks BBVA and Banamex experienced widespread outages affecting mobile applications and electronic transfer services. The technical failures occurred during a peak payroll day, causing issues with login capabilities and delays in interbank transfers.

Following these service disruptions, regulatory and institutional shifts were introduced to improve the digital banking environment. The Bank of Mexico (Banxico) announced new protocols to simplify electronic transfers by allowing the use of alternative identifiers or aliases instead of traditional long account numbers by December 2026. Concurrently, BBVA implemented new security measures, such as disabling the ability to take screenshots of transfer confirmations within its app to protect sensitive user data.
