How CME’s New Clearing House Will Support Market Efficiency and Cross-Margining
A central component of CME Securities Clearing will be its ability to offer capital efficiencies through enhanced cross-margining with the Fixed Income Clearing Corporation (FICC).

By supporting clearing for both “done-with” executions—where trades are executed and cleared through CME—and “done-away” executions—where trades are executed elsewhere but cleared through CME—firms will have broader discretion in choosing how they route trades while still meeting regulatory obligations. This flexibility is particularly valuable for large asset managers, hedge funds, and primary dealers viewking to optimize execution strategies without sacrificing clearing efficiency.

As firms upgrade workflows, connectivity, and collateral practices to align with new regulatory requirements, CME’s participation adds a diversified infrastructure model designed to better accommodate increases in trading volumes and settlement demands.
