CME ClearPort and CME Globex Risk Limits Aligning with SPAN 2 Margin Framework

Starting Sunday, September 10, 2023 (for trade date Monday, September 11), the Account Management Service for risk limit setting for CME ClearPort and CME Globex will be updated to align with the roll out of the SPAN 2 Margin Framework to all clearing firms and clients. Risk limit methodologies will remain the same and will be enhanced to incorporate SPAN 2 risk data for computing portfolio requirements.  

Clearing Members are encouraged to review client limits as CME Clearing moves to the SPAN 2 methodology.

A new SPAN 2 Approximation File will be used for computing SPAN 2 margin requirements for CME Globex Credit Controls and CME ClearPort (RAV Limit calculation). Please review the Client Impact Assessment for full technical details about this file and launch.  

Firms interested in computing SPAN 2 requirements to match the clearing system can use CME CORE, our online web-based calculator which has both a UI and API for integration. CME CORE is not intended for low latency pre-trade use cases. 

In the unlikely event that Traders and Brokers experience an application error, please contact the CME Group Global Command Center. For a risk limit error, contact your Clearing Member.
