What Is the Difference between Initial Margin and Variation Margin as Used by a CCP?
Initial margin (IM) is the collateral required upfront to open a derivatives position. It is intended to cover the potential loss on the position until it can be liquidated following a default.
Variation margin (VM) is the daily cash flow paid or received to reflect the mark-to-market change in the position's value. IM covers potential future losses, while VM settles current daily gains or losses.
