The Chile Financial Market Commission has issued an amendment to General Rule No. 258, updating minimum credit risk and liquidity management requirements for systems that clear and settle financial instruments by adding instructions on bilateral portfolio compression in central counterparty (CCP) systems. The amendment sets out a process to extinguish previously accepted clearing orders and replace them with new “carryover orders”, enabling a reduction in the number of contracts and notional value while keeping net counterparty portfolio risks and collateral requirements unchanged. It also establishes compression requirements for CCPs and their participants, including traceability of operations before and after compression, and is accompanied by a Regulatory Report published by the Commission.
