SEC Approves Exemptive Order and Proposed Rule Change to Permit Customer Cross-Margining in the U.S. Treasury Market

Impact. This rule enables Treasury market participants to cross-margin customer cash and derivatives positions for the first time, reducing customer margin requirements and freeing up capital for Treasury trading activities. Dually-registered broker-dealers with joint FICC and CME clearing membership must now build operational infrastructure to calculate and manage cross-margined positions across both cash Treasury securities and Treasury futures.

Risk. Operations teams face the highest exposure as they must coordinate clearing processes between previously siloed cash and derivatives systems without established playbooks. Risk management functions are equally vulnerable since cross-margining calculations introduce model complexity that could mask concentration risk or produce inaccurate margin requirements during periods of Treasury market stress.

Recommended Action. Treasury Trading and Clearing Operations leadership should immediately assess current system capabilities against the new cross-margining requirements and identify integration gaps between FICC and CME clearing platforms. Engage technology vendors now to scope system modifications needed for real-time cross-margining calculations and establish project timelines for operational readiness.

Watch. Monitor FICC and CME for published technical specifications and operational guidance on cross-margining mechanics, as clearing organizations typically release detailed implementation standards within 60-90 days of rule effectiveness.
