The Markets in Financial Instruments (Equivalence) (United States of America) (Commodity Futures Trading Commission) Regulations 2024 (SI 2024/638) were made on May 14, 2024 and entered into force on June 4, 2024. In preparation for Brexit, the U.K. onshored the EU's 2017 equivalence decision for the legal and supervisory framework applicable to designated contract markets and swap execution facilities in the U.S. for the purposes of the trading obligation for derivatives under the Markets in Financial Instruments Regulation. MiFIR requires that derivatives declared subject to the derivatives trading obligation must be traded on U.K. trading venues or third-country trading venues following an equivalence decision by HM Treasury. The onshored 2017 equivalence decision covers designated contract markets and swap execution facilities supervised and authorized by the Commodity Futures Trading Commission, and ensured that, when the U.K. left the EU, U.K. counterparties could continue to satisfy the DTO when they trade derivatives instruments on covered DCMs and SEFs.

HM Treasury has committed to reviewing the U.K.'s equivalence decision under the Smarter Regulatory Framework. In addition, HM Treasury considers that the CFTC's regime remains equivalent to U.K. MiFIR. The new Regulations therefore revoke and replace the onshored 2017 equivalence decision, updating the list of trading venues to include all current CFTC-authorized DCMs and SEFs.
