How to Read a Perp Futures Insurance Fund — 60 chars

By Editorial Team · July 2026

Who This Is For

This guide is for intermediate crypto traders who use perpetual futures and want to understand how the insurance fund protects your positions, prevents auto-deleveraging, and impacts your trading risk.

What You’ll Need

• A funded account on a major perpetual futures exchange (Binance, Bybit, dYdX, or Kraken)
• Basic understanding of leverage, margin, and liquidation in perp markets
• Access to the exchange’s insurance fund dashboard or explorer (usually in the “Risk” or “Insurance” section)
• Patience to read through one funding rate cycle and one liquidation event

Step 1: Understand the Bankruptcy Price

Every perpetual futures position has a liquidation price and a bankruptcy price. The liquidation price is where the exchange closes your position. The bankruptcy price is where your entire margin is wiped out. If the market moves fast and the filled liquidation price is worse than the bankruptcy price, the exchange takes a loss. That’s where the insurance fund steps in.

For example, if you’re long BTC at $60,000 with 10x leverage, your bankruptcy price might be around $54,545. If the market crashes to $52,000 and your position is liquidated at $51,800 (worse than bankruptcy), the exchange loses the difference. The insurance fund covers that $1,800 shortfall so other traders don’t get force-closed to cover it.

This mechanism is critical because without it, auto-deleveraging (ADL) would kick in — profitable traders would have their positions closed to compensate the losing party. The insurance fund is the buffer that keeps ADL rare.

Step 2: Find the Insurance Fund Dashboard

Most top exchanges display their insurance fund size publicly. On Binance, go to the “Risk” page under Derivatives. On Bybit, check the “Insurance Fund” tab in the footer. On dYdX, the insurance fund is visible on the stats page. You’re looking for a number — typically in USD or Bitcoin — that shows the current balance of the fund.

As of mid-2026, Binance’s insurance fund has fluctuated between $600M and $800M, Bybit’s is around $400M, and dYdX’s is roughly $50M. These numbers give you a sense of how much cushion the exchange has against extreme market moves. A fund under $20M on a high-volume exchange is a red flag — it means a single large liquidation event could drain the fund and trigger ADL.

You should also check the fund’s transaction history. Look for “top-ups” (when the exchange adds money, usually from liquidation fees or insurance fund premiums) and “drawdowns” (when the fund pays out to cover a loss). Frequent drawdowns suggest the exchange’s liquidation engine isn’t working well.

Step 3: Learn How the Fund Gets Funded

The insurance fund doesn’t come from thin air. Exchanges use a portion of the liquidation fees — typically 0.5% to 2% of the liquidated position value — to grow the fund. When a trader is liquidated, the exchange keeps that fee and adds it to the insurance fund. Over time, with thousands of liquidations, the fund grows.

But here’s the twist: if the liquidation engine is efficient and fills near the bankruptcy price, the fund barely gets touched. If the engine is slow or slippage is high, the fund takes a hit. Exchanges with better matching engines and lower latency tend to have healthier funds.

Some exchanges also use a portion of the funding rate paid by traders to fund the insurance pool. This is less common but happens on platforms like Kraken Futures. The key point is that the fund is a real reserve, not a fictional number — it’s backed by exchange revenue and actual assets.

Step 4: Watch for Auto-Deleveraging (ADL) Risk

Auto-deleveraging is the emergency mechanism that kicks in when the insurance fund is empty or insufficient to cover a loss. Profitable traders are selected — usually those with the highest leverage and longest position holding time — and their positions are partially or fully closed at the bankruptcy price. This is painful because you’re forced to exit a winning trade.

The insurance fund directly reduces ADL risk. When the fund is large, ADL is rare. When the fund is depleted, ADL becomes common. You can check the current ADL indicator on most exchanges — it’s often a tiered system showing how close the fund is to triggering ADL. A green indicator means low risk. Red means high risk.

As a trader, you can mitigate ADL risk by using lower leverage (3x-5x instead of 50x) and by monitoring the insurance fund size before entering large positions. If the fund is shrinking, consider reducing position size or moving to a different exchange.

Step 5: Compare Insurance Funds Across Exchanges

Not all insurance funds are equal. Some exchanges publish their fund size on-chain using smart contracts (like dYdX and GMX), making the data verifiable. Others (like Binance and Bybit) use off-chain databases that you have to trust. For risk-aware traders, on-chain funds are preferable because you can audit the balance yourself.

Here’s a quick comparison table based on mid-2026 data:

The takeaway: size matters, but transparency matters too. A $12M on-chain fund on GMX is riskier than a $700M off-chain fund on Binance, but at least you can verify the GMX fund. If you’re trading large sizes, prioritize exchanges with both large and transparent funds.

Step 6: Integrate the Insurance Fund Into Your Risk Plan

Once you understand the fund, you can use it to make smarter trading decisions. Before opening a position, check the insurance fund size and trend. If the fund is growing or stable, ADL risk is low. If the fund is declining after a series of large liquidations, consider reducing leverage or waiting for the fund to replenish.

You can also set alerts for insurance fund drawdowns. Some exchanges offer API endpoints for fund balance — you can build a simple script to notify you when the fund drops by more than 10% in 24 hours. This is a leading indicator that the exchange is under stress.

And don’t forget: the insurance fund is only one piece of your risk management. You still need stop-losses, position sizing, and diversification. The fund protects the exchange’s system, not your individual trade. Use it as a trust signal, not a safety net.

Common Pitfalls and Risks

⚠️ Risk: Assuming the insurance fund is infinite. Many traders think the fund will always cover losses, but it can be exhausted. During extreme volatility (like a flash crash), the fund can drain in minutes. Mitigation: Always use stop-losses and never rely solely on the insurance fund to protect your account.

⚠️ Risk: Ignoring ADL indicators. Exchanges show ADL tiers, but many traders ignore them. If you’re in the top ADL tier during a volatile period, you’re first in line to be force-closed. Mitigation: Check your ADL ranking regularly and reduce leverage if you’re in the top 10%.

⚠️ Risk: Trading on exchanges with opaque insurance funds. Some smaller exchanges don’t publish fund data at all. This is a huge red flag — if the exchange doesn’t show the fund, it might not exist. Mitigation: Only trade on exchanges that publicly display insurance fund size and transaction history.

What Next?

Now that you understand the insurance fund, check the fund size on your primary exchange and compare it to the table above to assess your current ADL risk exposure.
