The Commodity Futures Trading Commission’s Market Participants Division and Division of Enforcement released procedures for CFTC-registered non-US swap dealers and major swap participants relying on substituted compliance, setting out how staff will respond to potential non-compliance with foreign requirements deemed comparable to the Commodity Exchange Act or CFTC regulations. The procedures are framed around international comity and deference to the relevant foreign regulator, including that the foreign regulator interprets and applies the home-country rules. CFTC staff generally will not pursue an inquiry where the foreign regulator has determined the firm is in compliance with the comparable standards, or where the foreign regulator is addressing the issue through its supervisory process. Substituted compliance inquiries will be handled by the Market Participants Division unless it determines a supervision or non-compliance issue is material and refers it to the Division of Enforcement under CFTC Staff Letter 25-13. The procedures were developed following a guidance request jointly submitted by the Institute of International Bankers, the International Swaps and Derivatives Association, and the Securities Industry and Financial Markets Association.
