Insurance Funds: Covering Futures Liquidation Shortfalls | NOONOO TRADING
If a 10x long is liquidated and the loss ends with the margin rather than a negative account balance, an insurance fund may have absorbed the remaining shortfall. Its role is usually invisible, but a depleted fund can lead to forced closure of profitable positions on the other side.
What does an insurance fund do?
An insurance fund is an exchange's buffer for shortfalls that forced liquidation fails to recover. Despite the name, it is not a policy that traders separately purchase. The source describes it as accumulating and spending through the futures liquidation process.
Its purpose follows from how forced liquidation works. An exchange takes over a position and closes it in the market. The execution price is not predetermined. A deep order book may allow an expected fill, while an empty book during a crash can produce a much worse one. Someone must cover the unrecovered amount; the fund fills that role.
The guide describes this mechanism as allowing losses at most exchanges to stop at the committed margin. In its isolated-margin example, depositing $800 means losing that $800 at worst rather than receiving a demand to cover a negative balance. This protection is a feature of the described system, not a universal assumption.
Liquidation and bankruptcy prices: where contributions arise
The key is that liquidation price and bankruptcy price are different.
Bankruptcy price is where position equity reaches zero. Liquidation price starts the exchange's liquidation process and is somewhat higher for a long. The maintenance margin rate, MMR, creates this gap. Acting before equity is exhausted provides a buffer against adverse movement during execution.
Entry $68,000; quantity 0.1 BTC.
Notional $6,800; margin $680.
MMR 0.5% → maintenance margin $34.
Bankruptcy price = 68,000 × (1 − 1/10) = $61,200.
At this price the $680 margin is exhausted.
Liquidation price = 68,000 − (680 − 34) ÷ 0.1
= 68,000 − 6,460 = $61,540.
Gap: $340, the recovery buffer in this model.
Suppose liquidation triggers at $61,540 and sufficient orders allow a fill at $61,450. The original narrative describes a $90 difference at this point; the accompanying calculation below uses the stated fill and bankruptcy prices, whose difference is $250.
Fill: $61,450, which is $250 above bankruptcy at $61,200.
Excess recovery = 0.1 × 250 = +$25.
Under the source's assumed mechanism, the $25 is not returned to the trader.
→ It is contributed to the insurance fund.
Trader's loss: the entire $680 margin.
This can cause confusion: why not return the amount recovered above bankruptcy? The source says that most exchange terms allocate the residual to the fund. This is why it regards being liquidated as an especially adverse outcome: money that might remain after a voluntary stop is lost. The liquidation calculator can estimate the level in advance.
When the fund pays: execution beyond bankruptcy
The reverse situation reduces the fund. During a crash, missing orders can push liquidation execution below the bankruptcy price.
Same position, but the order book is sparse during a crash.
Trigger $61,540 → actual fill $60,900.
The fill is $300 below bankruptcy at $61,200.
Shortfall = 0.1 × 300 = −$30.
The insurance fund covers $30.
→ The trader still loses only the $680 margin in this example,
with no negative account balance.
The source describes ordinary contributions as usually exceeding withdrawals, gradually increasing the balance. A liquidation cascade changes this: forced selling pushes prices down, triggers more liquidation and further empties the book. Many fills can occur beyond bankruptcy, consuming months of contributions within hours.
Starting fund: $40 million.
Ordinary net growth: +$200,000 per day.
Crash shortfalls: −$9 million per hour.
Three hours → −$27 million.
Remaining balance: 40 − 27 = $13 million.
The original guide describes this as 45 days of ordinary contributions disappearing in three hours.
These are hypothetical structural examples, not measured fund activity.
What happens when the fund is insufficient? ADL
Uncovered losses do not vanish; they can affect profitable positions on the opposite side through auto-deleveraging, ADL. The exchange selects and forcibly reduces or closes opposing profitable positions.
The selection is not random. The source describes a ranking based on profitability multiplied by leverage, placing highly profitable, highly leveraged positions first. A trader who correctly anticipated a crash with a short can be closed before the target is reached—because the position is profitable, rather than because its direction was wrong.
Many exchanges display ADL priority with illuminated indicators on the position screen. The source interprets a full indicator as high priority on the profitable side of an imbalanced market. It suggests considering partial profit-taking instead of insisting on the final target when gains are large.
Where to find balances and how to read them
Major exchanges publish insurance-fund balances, often with historical charts. The guide proposes three checks.
1. Trend rather than absolute size. Even a large fund declining for weeks may indicate liquidation losses exceeding contributions. A gradual upward trend suggests ordinary operation in this framework.
2. Balance relative to open interest. A $100 million fund against $1 billion in open interest is ten times the relative buffer of the same fund against $10 billion. A constant fund becomes relatively thinner as the market grows.
3. Separate versus pooled funds. Some venues separate funds by contract or asset; others pool them. In a shared pool, an incident in a small altcoin can increase ADL exposure for BTC positions. Check this when trading illiquid altcoin futures.
Practical implications
The source identifies high leverage as both a driver and a victim of fund depletion. It argues that higher leverage leaves less room between liquidation and bankruptcy and makes gaps easier to jump during volatility. In this explanation, 100x leverage is dangerous not only because liquidation is frequent, but because orderly execution has little room.
The guide favors stops over liquidation. A voluntary stop seeks execution near the chosen level and leaves remaining margin in the account. Its described liquidation mechanism transfers residuals to the fund and may add liquidation fees. The same directional mistake can therefore have different financial consequences.
Account for liquidation when sizing. Calculating position size from the intended stop distance is presented as reducing the likelihood of reaching liquidation and the relevance of fund or ADL exposure. Check whether margin is cross or isolated. Cross margin uses the broader account as collateral, delaying liquidation in the source's comparison but exposing that account balance when it happens.
Three key points
1. An insurance fund covers liquidation shortfalls beyond bankruptcy, allowing losses to stop at margin in the described mechanism.
2. Favorable liquidation recoveries contribute to the fund, while crashes with empty books can deplete it quickly.
3. An insufficient fund can trigger ADL against profitable opposing positions, with high profitability and leverage raising priority in the source's ranking model.
Caution
All liquidation prices, bankruptcy prices and fund balances above are hypothetical calculations, not measured exchange data. MMR, liquidation fees, residual handling, separate or pooled funds and ADL rankings differ by exchange. Check the venue's own documentation before trading. An insurance fund does not reimburse your trading losses, and extreme conditions can exhaust it and force profitable positions to close. Leveraged trading can lose all principal; investment decisions and responsibility remain your own.
