CME is pleased to announce an enhancement to CME CORE, CME’s interactive margin calculator tool. The enhancement supports CME Securities Clearing contracts for margin processing, allowing users to replicate or estimate margin results for all contracts traded on CME’s securities clearing house. This feature does not currently support CME futures versus CME SC cross-margin workflows. This new feature is available in CORE’s Margin Calculator → Securities Clearing page for entitled users. This enhancement is currently available in CORE’s test environment and is expected in the production environment in November 2026. A subsequent advisory will be issued following the successful production launch.
