Marex Enables USDC as Collateral for Derivatives Margin
Event summary
- Marex Group Limited now allows clients to post USDC as initial margin collateral for derivatives, enabled by Coinbase's infrastructure.
- The move follows a December 2025 CFTC no-action letter permitting digital assets like USDC, Bitcoin, and Ethereum as customer margin collateral.
- Prime Trading LLC executed the first transaction using USDC as collateral, with Coinbase providing custody, settlement, and reporting support.
The big picture
Marex's move reflects the growing convergence of traditional finance and digital assets, driven by regulatory clarity and technological advancements. The ability to post USDC as collateral addresses inefficiencies in legacy banking rails, enabling near real-time risk management. This shift could accelerate the broader adoption of tokenized collateral across global derivatives markets.
