What Is the Significance of the “Variation Margin” in Daily Collateral Management?

Variation Margin (VM) is the amount of collateral exchanged daily between counterparties to cover the change in the market value (Mark-to-Market or MtM) of a derivatives position. It ensures that the exposure is settled daily, preventing the build-up of large unrealized losses.

This daily settlement process significantly reduces the credit risk exposure over the life of the derivative.
