What Is a Crypto Insurance Fund?
An insurance fund is a reserve pool maintained by the exchange that covers the deficit when a liquidated position closes below its bankruptcy price — protecting profitable traders from having their gains clawed back.
Every major futures exchange — Bybit, Binance, OKX, Deribit — maintains an insurance fund. It's a pool of capital set aside to absorb losses when a liquidated position cannot be closed at a price that fully covers the trader's losses. Without it, the deficit would have to come from somewhere — and historically, that somewhere was other traders' profits.
I've been trading derivatives on Bybit and Deribit since 2020. The insurance fund is one of the most important structural protections in futures trading — but it's also one of the least understood. Most traders don't think about it until they get hit with ADL on a winning position, which is exactly when it becomes very real.

Why It Was Created: The Socialized Loss Problem
Before insurance funds became standard, exchanges used a model called socialized loss (or clawback): at the end of each trading session, if aggregate liquidations resulted in a net deficit, all profitable traders had a proportional amount of their gains confiscated to cover it. BitMEX operated this model until 2019. It was unpredictable, unfair, and deeply unpopular. Insurance funds replaced clawbacks as the industry standard, starting with Bybit and Binance Futures in 2019.
How the Insurance Fund Is Funded
The fund grows when liquidations close above the bankruptcy price — the surplus margin from a liquidated position flows directly into the insurance reserve. The fund shrinks when a liquidation fills below bankruptcy price and needs to be covered.
When a trader gets liquidated, the exchange's liquidation engine takes over the position and attempts to close it in the open market. If it closes at a price better than the bankruptcy price — meaning the trader still had some margin left over after closure — that surplus goes into the insurance fund. This is the primary mechanism by which the fund grows during normal market conditions.
On Deribit, each asset has its own fund: BTC positions feed the BTC pool, ETH feeds the ETH pool, USDC-settled positions feed the USDC pool. Deribit does not cross-subsidise between asset pools. This means a crash in BTC that depletes the BTC insurance fund would not automatically draw from the ETH fund — which is both a limitation and a form of risk isolation.
Fund Flow Mechanics
Liquidation fills above bankruptcy price → Fund gains
Trader's margin: $1,000 at bankruptcy. Liquidation fills at $1,300. $300 surplus goes to the insurance fund. This is the normal case — fund grows steadily.
Liquidation fills below bankruptcy price → Fund pays
Trader's margin: $1,000 at bankruptcy. Market moves fast, liquidation fills at $700. $300 deficit is covered by the insurance fund. This is what the fund exists for.
Multiple simultaneous deficits exceed fund balance → ADL triggers
In a flash crash with many large positions liquidated simultaneously, the fund can be overwhelmed. When fund balance would go negative, ADL activates to close profitable counterparties.

What Is the Bankruptcy Price?
Bankruptcy price is the level at which a trader's entire margin is completely exhausted — any fill below it (for a long) means the exchange takes a loss that must be absorbed by the insurance fund.
When you open a leveraged futures position, three price levels are calculated automatically: your entry price, your liquidation price (where you get force-closed, with some margin still remaining for fees), and your bankruptcy price (where your margin hits exactly zero). The gap between liquidation price and bankruptcy price is the maintenance margin buffer — it's the small amount of margin kept in reserve to cover liquidation costs.
Worked Example: BTC 10x Long at $85,000
| Price Level | Price | What Happens |
|---|---|---|
| Entry Price | $85,000 | Position opened. $8,500 margin posted (10x leverage). |
| Liquidation Price | ~$77,000 | Exchange force-closes your position. Some maintenance margin remains. |
| Bankruptcy Price | ~$76,500 | Your entire $8,500 margin is exhausted. Any fill below this = deficit. |
| Fill at $76,800 | $76,800 | $300 above bankruptcy. $300 surplus goes into insurance fund. ✓ |
| Fill at $76,200 | $76,200 | $300 below bankruptcy. $300 deficit covered by insurance fund. |
Illustrative example. Actual bankruptcy price depends on maintenance margin rate per tier.
The Gap Between Liquidation and Bankruptcy
At typical leverage levels, the gap between liquidation price and bankruptcy price is small — usually 0.5–1% of the position value. This gap represents the maintenance margin buffer. It's designed to give the liquidation engine enough runway to close the position at or above bankruptcy price in normal markets. Fast-moving markets — particularly thin altcoin pairs at high leverage — are where this buffer can be insufficient.
What Happens When the Fund Runs Out — ADL
When the insurance fund cannot cover a deficit, Auto-Deleveraging (ADL) triggers — automatically closing the positions of the most profitable and most leveraged traders on the winning side to absorb the remaining loss.
ADL replaced the old socialized loss model. Instead of spreading losses evenly across all winners, ADL targets specifically: the traders who are both most profitable AND most leveraged. The logic is that high-leverage highly-profitable positions are effectively the counterparty to the excess risk — so they bear the ADL exposure first.
When ADL fires against you, your position is closed at the mark price with zero fee. You receive a notification. You don't lose more than your unrealised profit on that position — ADL cannot force you into a loss. But it does forcibly exit a winning position, which is disruptive, especially in momentum trades.
ADL Priority Ranking
ADL ranking = unrealised profit × effective leverage × position size. The higher this score, the more likely you are to be auto-deleveraged when ADL activates.
Highest ADL risk
5 lit bars on ADL indicator. Large long BTC 100x, deep in profit.
Moderate ADL risk
3 lit bars. Mid-size altcoin perp, 20x leverage, +40% unrealised P&L.
Lowest ADL risk
1 lit bar. Conservative 2x long, minimal unrealised profit.

Insurance Fund vs ADL vs Socialized Loss
The insurance fund is the first line of defence; ADL is the last resort backstop; socialized loss was the old industry model that all major exchanges have abandoned.
Understanding the hierarchy is important: in the vast majority of liquidation events, the insurance fund handles everything and no trader is affected beyond their own margin. ADL is genuinely rare on major exchanges with large, healthy funds. Socialized loss is historical — if you're on a major exchange today, you will not face clawbacks.

Insurance Fund Size — Bybit, Binance, Deribit
A larger, growing insurance fund is a key safety indicator when evaluating a futures exchange. All three major exchanges publish live fund balances — check them before opening large positions.
Fund size matters for two reasons: first, a larger fund can absorb more simultaneous liquidation deficits without triggering ADL. Second, a growing fund over time signals that the exchange's liquidation engine is performing well — surplus liquidations consistently exceed deficit liquidations. A declining fund is a warning sign worth monitoring.

How to Check Your ADL Risk
Bybit and Binance both display a real-time ADL indicator on every open position — five bars ranging from grey (low risk) to fully lit red (highest ADL priority). Five lit bars means you're first in line if ADL activates.
The ADL indicator updates in real-time as your unrealised P&L and leverage change relative to other traders on the same contract. When you're deep in profit on a high-leverage position, your bars light up more. When prices move against you (reducing unrealised profit) or you reduce leverage, your ADL ranking drops.
How to Reduce ADL Risk — 3 Practical Moves
Cut leverage on profitable positions
The ADL formula weights effective leverage heavily. Reducing from 50x to 10x on a deep-profit position dramatically lowers your ADL ranking — often dropping from 5 bars to 2.
Take partial profits
Realizing 50% of your unrealised profit reduces your position's contribution to the ADL ranking score. The fund only gets depleted on large sustained moves — taking profits reduces exposure.
Reduce position size on high-conviction holds
If you're running a large winning position and want to hold, scale down the size. Smaller size = lower ADL rank even at the same leverage and profit percentage.
ADL Executes at Mark Price — Zero Fee
If ADL fires against your position, it closes at the current mark price with no trading fee charged. You receive the full mark price value of your position. The loss relative to your expectations is opportunity cost — not a forced loss below current market price. ADL will never force you into a negative P&L.
Does the Insurance Fund Protect Your Deposits?
No — the insurance fund only covers liquidation shortfalls. It has nothing to do with exchange hacks, insolvency, theft, or technical failures. These are entirely different risk categories.
This is the single most important clarification about insurance funds. When FTX collapsed in November 2022, traders lost billions in deposited funds. FTX had an insurance fund. The insurance fund did nothing — because the losses were from insolvency and fund misappropriation, not liquidation deficits. The insurance fund only addresses one very specific scenario: a liquidation that closes below bankruptcy price.
For broader exchange safety, the relevant checks are: Proof of Reserves audits (do they actually hold your funds?), regulatory licensing (VARA, FCA, CFTC), and platform track record. Bybit publishes monthly Proof of Reserves. Binance publishes real-time PoR via Merkle Tree. These are the tools for assessing deposit safety — not the insurance fund.
What the Insurance Fund Covers vs Doesn't Cover
What It Covers
What It Does NOT Cover
Proof of Reserves is the right tool for verifying deposit safety. Bybit publishes monthly PoR audits. Binance uses a live Merkle Tree PoR system. Checking these — not the insurance fund — is how you verify an exchange actually holds your funds.
Pros and Cons of the Insurance Fund Model
Pros
Protects winners from clawbacks
You keep your full profit even when another trader's liquidation results in a deficit. The fund absorbs it, not you.
Prevents cascade liquidations
By covering shortfalls quickly and fairly, the fund stops small liquidation deficits from spiralling into broader market instability.
Real-time fund sizes published
Bybit, Binance, and Deribit all publish live insurance fund data. A growing fund is a positive safety signal for any futures exchange.
Replaced the old clawback model
Before insurance funds, profitable traders could face clawbacks — losing part of their realised P&L after a session close. Insurance funds ended this on all major exchanges.
Cons
Doesn't protect against insolvency
The insurance fund only covers liquidation shortfalls. If an exchange is hacked, insolvent, or commits fraud (FTX), the insurance fund is irrelevant.
Extreme crashes can deplete it
In a simultaneous mass liquidation event, even a large insurance fund can be exhausted. ADL kicks in as the backstop, but it means your winning positions get closed.
ADL risk remains in worst-case
The insurance fund is the first line of defence, not the last. If it empties, you bear ADL risk proportional to your leverage and unrealised profit.
FAQ
A crypto insurance fund is a reserve pool maintained by futures exchanges that covers the deficit when a liquidated position closes below its bankruptcy price. Without it, the unrecoverable loss would be spread across all profitable traders — known as socialized loss or clawback. The insurance fund is funded by surplus margin from liquidations that close above the bankruptcy price.
Trade futures on exchanges with robust insurance funds
Bybit and Binance both maintain industry-leading insurance funds, publish live fund balances, and display real-time ADL indicators on every open position. Knowing your fund's health and your ADL ranking is basic futures risk management — these two exchanges make it easy.
