Margin Call Risk

Margin call risk is the danger that a trader will be required to deposit additional collateral to maintain a leveraged position because the value of the initial collateral has fallen. In derivatives trading, this occurs when market movements cause the account equity to drop below the required maintenance margin level.

If the trader fails to provide the extra funds, the broker or protocol automatically liquidates the position to cover potential losses. This risk is amplified in the cryptocurrency market due to 24/7 trading and extreme volatility, which can lead to margin calls occurring at any time, including during low liquidity hours.

It is a critical component of systems risk, as mass margin calls can lead to wider market contagion. Managing this risk involves maintaining conservative leverage ratios and keeping sufficient liquidity available.
