Marex offers clients ability to post USDC as margin for derivatives

Marex Group Limited said it will allow clients to use USDC as margin for derivatives, expanding the set of collateral options available to trading participants. The announcement, made in New York on July 16, 2026, ties the plan to USDC, described as a regulated, fully reserved dollar-denominated stablecoin issued by Circle. Marex, which trades on NASDAQ under the ticker MRX, positioned the change as part of its diversified financial services platform. The company did not provide additional implementation details in the supplied text, including timelines for roll-out, the specific derivative products covered, or any limits on USDC usage.
