LCH's robust risk management framework – underpinned by a team of over 50 dedicated risk managers – affords exceptional levels of protection to clearing members.

Initial and variation margin is collected from LCH members; should they fail, this margin is used to fulfil their obligations.

The amount of margin is decided by LCH's risk management teams, who assess a member's positions and market risk on a daily basis.
