Margin Clearing
Margin clearing is the process by which a central counterparty or exchange ensures that all parties to a financial contract fulfill their obligations. When a trader opens a leveraged position, they must deposit collateral, known as margin, to cover potential losses.
The clearing house monitors these positions in real-time, marking them to market to reflect current price changes. If a trader's account equity falls below a specific maintenance threshold, the clearing system initiates a margin call or automatic liquidation.
This mechanism prevents the buildup of counterparty risk by ensuring that winners get paid and losers have sufficient capital to cover their deficits. It acts as the fundamental risk management layer in derivatives and cryptocurrency futures markets.
By centralizing this process, the clearing house acts as the buyer to every seller and the seller to every buyer, stabilizing the financial ecosystem. Without efficient margin clearing, a single default could trigger a cascade of failures throughout the market.
It is essentially the plumbing that keeps leveraged trading safe and orderly.
