Margin Requirement Adjustments
Margin requirement adjustments are the dynamic changes made by an exchange to the amount of collateral required to maintain a leveraged position. These adjustments are typically triggered by changes in market volatility or the liquidity profile of the underlying asset.
By increasing margin requirements during volatile periods, exchanges protect themselves and the broader system from the risk of cascade liquidations. Conversely, lowering requirements can stimulate trading activity during periods of stability.
This risk management tool is critical for maintaining the solvency of the exchange and ensuring that all positions can be settled according to the protocol's rules. It is a fundamental aspect of systemic risk management in derivative markets.
