Mexico's National Commission for the Protection and Defense of Users of Financial Services has published the results of its 2025 financial transparency supervision of 15 multiple banking institutions in relation to the credit card current account credit product. After the process was completed and identified irregularities were corrected, four institutions achieved a score of 10 and fully complied with the rules, while ten complied partially. The review was carried out in two stages. First, it examined customer files and disclosure material, including standard form contracts, cover sheets, account statements, transaction receipts, websites, brochures and, where applicable, advertising, to check whether information was clear, consistent and not misleading for users. Detected irregularities were notified through compulsory compliance notices, and the second stage assessed whether institutions corrected the findings and demonstrated compliance through supporting documents and arguments. The average score increased from 5.2 in the first stage to 8.3 at the end of the supervision. The exercise did not assess commissions, interest rates, total product cost or the suitability of any particular card.
