Overview
- Banxico and the CNBV published a revised anteproyecto on Thursday that is now in public consultation and would cap credit‑card interchange at 1.30% per operation with a 1.00% annual issuer cap.
- The proposal adds rules to force point‑of‑sale interoperability, limits non‑credit fees to a final ceiling of 10.80 pesos per transaction, and sets a 36‑month phased path with higher interim caps to ease the transition.
- The Confederación Nacional de Escuelas Particulares said bank‑driven merchant reclassification would strip a pandemic‑era 0% interchange for private schools and impose new debit and credit charges starting in October, a change schools warn could raise costs for families.
- The Asociación de Bancos de México says it does not set interchange rates and that merchants can negotiate commercial commissions with acquirers, leaving the final allocation of costs to regulatory outcomes and market deals.
- The rulemaking follows an earlier, tougher October 2025 draft that was paused after industry pushback and U.S. trade scrutiny, and the consultation will remain open through late September while authorities and stakeholders meet to define the final scope.
