The CFTC’s Division of Market Oversight on Tuesday amended Brexit-related no-action positions to add UK trading facilities OptAxe Limited and Capitolis UK Limited to Appendix A of Staff Letter 24-11, the regulator announced from Washington.
The update means both firms now sit inside the same no-action framework already covering other UK venues listed in the staff letter. The two platforms can continue to be used by US market participants under the temporary relief the CFTC has maintained since the UK’s withdrawal from the European Union.
The amendment is a staff-level administrative adjustment, not a broader rewrite of US-UK market access rules. The CFTC’s official release confirms only that DMO updated Appendix A and named the two additional eligible UK trading facilities.
Secondary industry coverage framed the move as part of the CFTC’s continuing effort to preserve derivatives trading continuity between US participants and UK venues after Brexit. Under the no-action framework, covered UK platforms can service US counterparties without the immediate need to register as designated contract markets or swap execution facilities under US law.
Post-Brexit pattern continues
The CFTC has issued a series of no-action letters since the UK left the EU, periodically updating its relief list to reflect changes in the UK trading landscape. Tuesday’s addition of OptAxe Limited and Capitolis UK Limited keeps the eligible venues list current rather than introducing new regulatory obligations.
The agency has used Appendix A as a live roster of qualifying venues, and the latest update adds two more names to it.
