What Is Initial Margin and How Does It Protect the Clearing House?

Initial margin is a collateral deposit required from both the buyer and the seller of a derivatives contract when they open a position. It is calculated to cover the potential loss the clearing house might incur if the member defaults and the clearing house has to close out the position.

It is a performance bond that is held until the position is closed.
