The Chile Financial Market Commission issued an amending regulation to General Rule No. 532 (Information Systems Manual for Funds, ISMF), delaying the start of ISMF-based reporting for fund managers and their funds until 1 June 2026. The changes adjust and clarify the information requirements used to supervise general fund managers and funds regulated under Law No. 20,712. The amendments add new fields and instructions for submitting regulatory files, revise the Funds 02 file by replacing mandatory submission of registries 01–04 with an obligation to report managed funds’ derivative transactions to the Central Bank of Chile through SIID-TR, and modify the calculation structure for funds’ cost rates in the Funds 03 file. They also remove the requirement to submit an XML file containing main variables of internal fund regulations and introduce a set of general tables for use in submissions. The amendments take effect upon issuance of the regulation, while ISMF submissions begin in June 2026. Reporting entities must continue submitting information under current regulations until November 2026.
