Overview
- Banxico and the CNBV closed a public consultation in September 2026 and are now reviewing comments before issuing final rules for Mexico’s payment networks.
- The draft disposals propose a three-year phase-down of interchange caps toward roughly 0.30% for debit and 1% for credit to cut costs for merchants and encourage acceptance.
- Regulators plan to clarify that Sofipos can act as acquirers and work with aggregators to onboard small, cash-focused merchants where traditional acquirers have low presence.
- Authorities are pressing Sofipos to match any digital expansion with stronger prudential measures, noting IFRS 9 took effect in January 2026 and a Liquidity Coverage-like CCL will begin phased implementation on January 1, 2028.
- Officials and industry leaders say lower per-transaction revenue will need to be offset by higher volumes and better fraud, governance and operational controls to protect consumers and institutional solvency.
