Forced Liquidation in Crypto: A Risk Amplifier for Leveraged Traders

On May 19, 2021, Bitcoin's price plummeted from $43,000 to $30,000 in just one day. This decline was not solely caused by sellers who wanted out of their positions, but also accelerated due to traders who had no choice but to liquidate their leveraged long positions.

Approximately $8.6 billion in leveraged long positions were forced closed across crypto exchanges within 24 hours, with each liquidation creating more selling pressure that further pushed the price lower. This created a self-reinforcing cycle of downward pressure on Bitcoin's price.

Leverage is borrowed exposure, where a trader deposits $1,000 and controls $10,000 in Bitcoin at a 10x leverage ratio. However, if the trade moves against the trader by just 10%, the entire $1,000 margin is gone, leaving the exchange holding the extended credit with no means to recover it.

Forced liquidation is the mechanism that prevents this outcome by setting a maintenance margin threshold and triggering an automatic closure when the account equity falls below it. This preserves a small buffer for the exchange to close the position at market before the margin reaches zero.
