How Does the Clearing House Manage the Risk of a Major Market Participant Default?
The clearing house manages this risk through a 'default waterfall' of financial resources. First, the defaulting member's margin is used.
Second, the clearing house's own capital (skin-in-the-game) is used. Third, a portion of the non-defaulting members' contributions to the default fund is used.
Finally, the clearing house may have the authority to call for additional contributions or even reduce the settlement obligations (tear-up). This multi-layered defense ensures stability.
