Meaning
Financial collateral payments are transferred daily between counterparties or through a clearing house to cover the changes in the market value of outstanding derivative positions. The variation margin represents this daily cash transfer, which reduces the credit risk of the clearing house by resetting the net exposure of each participant to zero at the end of every trading session. It ensures that a counterparty’s unrealized losses do not accumulate to a level that could trigger a default and destabilize the clearing system.
By making financial obligations immediate rather than deferring them to contract maturity, the payment system prevents default cascades in highly leveraged commodity markets.
Marginal Assessment
Clearing houses calculate the daily profit or loss for each outstanding contract based on the official closing settlement prices of the exchange. If a trader’s position has lost value, their account is debited, and the corresponding amount is credited to the account of the trader with the winning position. This daily cash movement prevents the build-up of massive, uncollateralized exposures during volatile market periods.
Risk Management
Corporate treasury departments must maintain highly liquid cash reserves or pre-arranged credit lines to meet these daily margin demands, especially during periods of high commodity price volatility. Failure to make a required payment by the designated deadline can result in the immediate liquidation of all outstanding positions by the clearing house. This strict enforcement protects the clearing house and its members from the default of a single participant.
Clearing Procedure
Standardized OTC derivative transactions use these transfers to satisfy the requirements of global financial regulations designed to reduce systemic risk. The terms of these payments are governed by credit support annexes that define the acceptable currencies and the timing of the cash transfers. This structure ensures that both parties maintain sufficient collateral to cover their potential losses at all times.
