Marex offers clients ability to post USDC as margin for derivatives

Marex Group Limited announced that clients can now use USDC stablecoin as initial margin collateral in derivatives trading, enabled through partnerships with Circle and Coinbase. The initiative follows a December 2025 CFTC no-action letter permitting digital assets as collateral. This enables 24/7 collateral management at internet speed, with Coinbase providing custody and infrastructure support. Prime Trading LLC executed the first transaction using this capability.
