The Central Bank of Mexico has launched a public consultation on draft amendments to its rules on the Legal Entity Identifier (LEI) code for legal entities and trusts and to its rules governing derivatives transactions, focusing on LEI usage and margin requirements. The proposals aim to strengthen identification of participants in Mexico’s financial system and facilitate aggregation of exposures. The draft changes would expand the regulatory application of the LEI in derivatives transactions conducted by entities subject to these requirements. They would also update the reference to State-owned public enterprises in the margin requirements for derivatives that are not centrally cleared. Draft texts and the consultation plan are available via the central bank’s online consultation portal, and comments must be submitted through that portal by 18:00 on 30 October 2025.
