Margin Call Threshold
A margin call threshold is the specific price level or collateral ratio at which a borrower is required to add more funds to their account to maintain their position. If the value of the collateral falls below this threshold, the protocol triggers a liquidation event, where the borrower's assets are sold off to repay the debt.
This mechanism is designed to protect the lender from loss, but it also creates significant stress for the borrower, especially in high-volatility environments. The threshold is typically determined by the loan-to-value ratio, which is set based on the volatility and liquidity of the collateral asset.
Understanding the margin call threshold is crucial for risk management, as it defines the safety buffer that a trader has before their position is forcibly closed. In a market downturn, many participants may hit their thresholds simultaneously, leading to a cascade of liquidations that can further depress prices.
