Regulatory Developments
CONDUSEF continues to modernize its regulatory framework. On October 14, 2022, the “Regulation on Registries before CONDUSEF” was published in the Official Gazette, consolidating various portals (SIPRES, RECA, RECO, REDECO, BURÓ, REUS, SINE, SIGE) into a unified system. Financial institutions must now use the Single Portal Registries (PUR) with CONDUSEF Institutional Identity Keys (CICI) for compliance.
This regulation standardizes electronic submissions, establishes common deadlines, and mandates that all promotions, requests, reports, and responses to requirements be sent with electronic signatures. It also formalizes the public disclosure of sanctions imposed by CONDUSEF.
