Collateral
Collateral refers to the assets that a trader deposits with an exchange to back their leveraged positions. This can be in the form of stablecoins, the native asset of the exchange, or the underlying asset being traded.
The collateral serves as a guarantee to the exchange that the trader can cover potential losses. If a trade goes against the trader, the exchange deducts the loss from the collateral.
If the collateral drops below the maintenance margin level, the liquidation process is initiated. The quality and liquidity of the collateral are important factors for the exchange's risk management.
Using highly liquid assets as collateral ensures that the exchange can quickly recover funds in the event of a liquidation. It is the foundation of credit and leverage in the derivatives market.
