Mexico's National Commission for the Protection and Defence of Users of Financial Services (CONDUSEF) published the fourth-quarter 2025 results of its User Service Attention Performance Index (IDATU) for credit unions, investment fund management companies and pensions, measuring how institutions handle and resolve user complaints. On a 10-point scale, credit unions scored 8.6 (down 0.04 points), while investment fund management companies scored 9.5 and pensions scored 9.4 (both up 0.02 points). The index assesses timeliness of attention, quality of responses and actions taken to improve complaint-handling processes, with emphasis on equitable treatment including for vulnerable groups such as older adults. Among the highest-scoring institutions were SURA Investment Management México (10.0) and Profuturo Pensiones (10.0), followed by Pensiones Banamex (9.78), Multiopciones Unión de Crédito (9.40), MetLife Pensiones México (9.31), BBVA Pensiones México (9.26), Pensiones Banorte (9.10) and Skandia Operadora de Fondos (9.10); the lowest score was Unión de Crédito Mexicano de Servicios Profesionales (7.90). CONDUSEF positioned IDATU as a transparency tool to help users compare providers, with full results available via the financial services bureau website (buro.gob.mx).
