Understanding the Insurance Fund in Bybit Contracts

The insurance fund on Bybit plays a crucial role in maintaining the stability and fairness of its perpetual and futures contract markets. When traders open leveraged positions, especially on the perpetual contract platform, there's always a risk of liquidation if the market moves sharply against them. In cases where a trader's position is liquidated, the system attempts to close the position at the best available price. However, during periods of high volatility, the liquidation price may differ significantly from the bankruptcy price, leading to a loss for the exchange known as a "clawback."

To prevent such losses from affecting other traders or the platform's solvency, Bybit maintains an insurance fund funded by surplus from liquidated positions. When a position is liquidated and closed at a price better than the bankruptcy price, the remaining equity is added to the insurance fund. This surplus acts as a financial buffer to cover any shortfall if a position is closed at a worse price than expected.

How the Insurance Fund Prevents Socialized Losses

One of the major concerns in derivatives trading is the possibility of socialized losses, where remaining profitable traders are forced to absorb the losses of others when a position cannot be liquidated in time. This typically occurs during flash crashes or extreme market movements when the order book lacks sufficient depth.

Bybit’s insurance fund ensures that such scenarios do not lead to unfair distribution of losses. If a liquidated position results in a deficit—meaning the system incurs a loss during forced closure—the insurance fund covers the deficit. This means that no other traders are charged or diluted in their profits due to another trader’s liquidation. The fund serves as a protective layer between isolated trader failures and the broader trading ecosystem.

This mechanism is especially important in high-leverage environments, where small price movements can trigger large liquidations. Without the insurance fund, cascading liquidations could destabilize the entire market and erode trader confidence.

Source of Funds: How the Insurance Fund is Built

The insurance fund is not funded by Bybit’s own capital or by charging users directly. Instead, it is self-sustaining and derived entirely from trader activity. Specifically, the fund grows when:

• A trader is liquidated and their position is closed at a price better than the bankruptcy price
• The difference between the liquidation price and the bankruptcy price results in positive surplus
• This surplus is automatically transferred into the insurance fund

For example, if a long position has a bankruptcy price of $10,000 but is liquidated at $10,100 due to favorable market conditions during closure, the $100 per contract surplus is added to the fund. Over time, consistent liquidations with positive outcomes contribute to a robust fund balance.

Bybit provides a transparent, real-time display of the insurance fund balance for each contract pair on its website. Traders can monitor the fund’s health, which adds a layer of trust and visibility to the platform’s risk management infrastructure.

Role During Extreme Market Volatility

During highly volatile market events, such as major news releases, exchange hacks, or macroeconomic shocks, cryptocurrency prices can gap significantly. This leads to rapid liquidations and potential slippage in the liquidation engine.

In such scenarios, the insurance fund acts as a shock absorber. If the mark price of a contract moves so quickly that the liquidation engine cannot close positions fast enough—or if the auction price falls below the bankruptcy price—the resulting loss is covered by the fund. This prevents the platform from defaulting on obligations and maintains orderly settlement.

For instance, during a sudden 10% drop in Bitcoin within minutes, hundreds of long positions may be triggered for liquidation. If the system closes these positions at prices below their bankruptcy levels due to thin order books, the accumulated deficit is paid from the insurance fund. This ensures that the exchange remains solvent and traders are not penalized unfairly.

Transparency and Real-Time Monitoring

Bybit emphasizes transparency in how the insurance fund operates. On the official Bybit website, under the derivatives section, users can view the current balance of the insurance fund for each contract, including BTCUSD, ETHUSD, and other major pairs. The fund is denominated in USD and updated in real time.

Traders can use this information to assess the resilience of the market during turbulent times. A larger fund balance indicates a greater capacity to absorb unexpected liquidation losses. Conversely, a low or rapidly depleting fund may signal increased systemic risk, especially during prolonged volatility.

Additionally, Bybit does not allow withdrawals from the insurance fund for any purpose other than covering liquidation shortfalls. This strict policy ensures the fund remains dedicated solely to protecting the integrity of the contract market.

Frequently Asked Questions

Can the insurance fund go negative?

No, the insurance fund cannot go negative. Bybit’s risk engine is designed to ensure that the fund always maintains a non-negative balance. If a large-scale liquidation event threatens to deplete the fund, Bybit may employ auto-deleververaging (ADL) as a secondary mechanism, though the insurance fund is the first line of defense.

Is the insurance fund shared across different contracts?

No, the insurance fund is segregated by contract pair. For example, the BTCUSD perpetual contract has its own dedicated insurance fund, separate from ETHUSD or other altcoin contracts. This isolation ensures that risks in one market do not directly impact another.

Does Bybit contribute its own money to the insurance fund?

Bybit does not routinely add its own capital to the insurance fund. The fund is entirely built from liquidation surpluses generated by traders. However, in extreme and unprecedented circumstances, Bybit reserves the right to support market stability, though such actions are rare and not part of standard operations.

What happens if the insurance fund is exhausted during a crash?

If the fund is insufficient to cover all liquidation deficits, Bybit activates the auto-deleververaging system (ADL). Under ADL, opposing profitable positions are reduced in reverse order of leverage to compensate for the shortfall. However, the insurance fund significantly reduces the frequency and severity of ADL events.
