What is the difference between a liquidation price and a bankruptcy price?

Liquidation Price Definition

1. Liquidation price refers to the asset price at which a leveraged position is automatically closed by the exchange’s risk engine to prevent further losses.

2. This mechanism activates when the position’s margin ratio falls below the maintenance margin requirement.

3. At this point, the exchange triggers a forced sale or buy-back of the position’s underlying asset.

4. The liquidation price is dynamically calculated based on entry price, leverage level, position size, and funding fees accrued.

5. It does not necessarily mean the trader has lost all capital—some equity may remain depending on slippage and execution conditions.

Bankruptcy Price Definition

1. Bankruptcy price is the theoretical price at which a trader’s equity balance reaches exactly zero.

2. It represents the absolute threshold where no margin remains to cover potential losses.

3. Unlike liquidation price, bankruptcy price assumes perfect execution with zero slippage and no fees.

4. Exchanges use this value internally to determine the maximum loss exposure per position before liquidation logic intervenes.

5. In practice, liquidation occurs slightly before reaching the bankruptcy price to preserve platform solvency.

Margin Mechanics in Derivatives Trading

1. Traders deposit initial margin to open a leveraged futures or perpetual swap position.

2. Unrealized PnL fluctuates with market price movement and directly impacts available margin.

3. Maintenance margin is a minimum equity threshold mandated by the exchange to sustain open positions.

4. When unrealized losses erode equity below maintenance margin, the system initiates liquidation procedures.

5. Funding payments, insurance fund offsets, and partial liquidation logic may adjust how close actual execution comes to the theoretical bankruptcy level.

Exchange-Specific Variations

1. Binance calculates liquidation price using a formula that includes entry price, leverage, and position direction—longs and shorts yield different values.

2. Bybit employs an “insurance fund-backed” model where bankrupt positions are absorbed by the fund after liquidation auctions.

3. OKX applies dynamic maintenance margin rates that increase with position size, altering both liquidation and bankruptcy thresholds.

4. Deribit uses a mark price-based liquidation trigger rather than last traded price to reduce manipulation risks.

5. BitMEX historically used a bankruptcy auction process where insolvent positions were settled against the insurance fund at bankruptcy price.

Frequently Asked Questions

Q: Does liquidation always occur at the exact liquidation price shown on the interface?No. The displayed liquidation price is an estimate. Actual execution depends on order book depth, mark price updates, and exchange-specific auction mechanisms.

Q: Can a position be liquidated even if the market hasn’t reached the listed liquidation price?Yes. If the mark price breaches the liquidation threshold due to volatility or index divergence, liquidation can trigger without the last traded price hitting that level.

Q: Is the bankruptcy price visible to users on most trading platforms?Most platforms do not display bankruptcy price directly. It is an internal reference used for risk engine calibration and insurance fund accounting.

Q: What happens to remaining equity after a liquidation event?If slippage during liquidation results in better-than-expected execution, residual equity may be returned to the user’s wallet—subject to exchange policy and fee deductions.
