Insurance Funds and Auto-Deleveraging: What Happens Behind a Futures Liquidation
When a liquidated futures position cannot be closed at a good price, exchanges rely on insurance funds and, rarely, auto-deleveraging. Learn how these mechanisms work and why they matter to profitable traders too.

In DeFi lending, liquidations are handled by on-chain bots and protocol rules that anyone can inspect. Centralised futures exchanges handle them differently. When a position is liquidated, the exchange tries to close it in the market; if the price obtained is worse than the bankruptcy price, an insurance fund absorbs the shortfall. In extreme conditions, when the fund is not enough, some exchanges use auto-deleveraging, reducing profitable opposing positions. This guide explains these mechanisms on Binance, OKX, Bybit and Bitget in practical terms.
From liquidation to the insurance fund
When margin falls below the maintenance requirement, the exchange's liquidation engine takes over the position and attempts to close it. If it closes at a better price than the level where the trader's margin would be exhausted, the remainder may go to the insurance fund. If it closes at a worse price, the fund covers the gap. Each exchange's help centre describes its process and often publishes insurance fund balances.
What auto-deleveraging means for you
In rare cases of extreme volatility, the insurance fund may be insufficient for a particular contract. Some exchanges then reduce positions on the opposite side, starting with those ranked highest by profit and leverage, to close the bankrupt position. This means even a profitable trader can see part of a position closed involuntarily. Exchanges usually display an indicator of your position's ranking in this queue.
Comparing with DeFi liquidations
In DeFi, liquidation thresholds, penalties and the handling of bad debt are encoded in smart contracts and visible on chain. On centralised exchanges, the rules are described in documentation and applied by the exchange's systems. Neither is free of risk. Understanding both helps you see where losses might come from in each environment, beyond simple price movement.
Practical steps for traders
Read the liquidation and auto-deleveraging sections of your exchange's help centre. Check the indicator showing your position's deleveraging priority if available, especially for large profitable positions in volatile markets. Use moderate leverage, keep stops well inside liquidation and take partial profits when appropriate. Record any involuntary reductions in your trading log so you understand their effect on results.

Scenario checkpoint
- Read how your exchange handles liquidation shortfalls and its insurance fund.
- Check the auto-deleveraging priority indicator on large profitable positions.
- Keep stops well inside the liquidation price to avoid entering the engine.
- Log any involuntary position reductions so their effect on results is visible.
