Globex Credit Controls (GC2) - Exposure Limits Update - This Week

On Monday, May 11, CME Group implemented distinct weekend and weekday exposure limits within Globex Credit Controls (GC2) in Risk Management Tools (RMT).

Clients authorized to trade products with weekend trading enabled are required to update their GC2 weekend exposure limits by 16:00 CT on this Friday, May 15.

If limits are not updated, this will result in the disabling of weekend trading capability, as the default limit is set to zero (0).

Firms are reminded that, pursuant to Rule 916, a Base Clearing Member must be approved to clear transactions for Base products (e.g., futures and options) that clear on the next business day during Supplemental Trading Hours (e.g., certain hours during the weekends), as defined in Rule 916. For more information, please refer to this Clearing House Advisory.

Details on setting exposure limits are available in the Globex Credit Controls (GC2) - User Manual.
