What is liquidation in crypto trading? It is the forced closing of a leveraged position by an exchange or protocol when your losses eat through most of the collateral (margin) backing it. Liquidation happens automatically at a calculated liquidation price, before your losses can exceed what you deposited, and you usually lose most or all of the margin on that position. It applies to futures, perpetuals and margin trades, and to DeFi loans. The higher your leverage, the closer the liquidation price sits to your entry, which is why small price moves can wipe out heavily leveraged traders.
Key takeaways
- Liquidation is the automatic closure of a leveraged position when margin falls below the maintenance requirement.
- For an isolated long, liquidation price ≈ entry × (1 − 1/leverage + maintenance margin rate).
- At 10x leverage, roughly a 9–10% move against you is enough to be liquidated; at 50x, about 1.5%.
- On 10–11 October 2025, more than $19 billion of leveraged positions were liquidated in about a day, according to CoinGlass data.
- Lower leverage, isolated margin, stop-losses and active monitoring are the main defences.

What is liquidation in crypto trading?
When you trade with leverage, you put up a fraction of a position’s value as collateral and effectively borrow the rest. A $1,000 deposit at 10x controls a $10,000 position. The exchange is now exposed: if the price moves far enough against you, your losses could exceed your $1,000 and the exchange would be left covering the gap. Liquidation is how it prevents that. For a fuller primer on how borrowed exposure works, see our guide to leverage trading in crypto.
Four terms explain the mechanics:
- Initial margin — the collateral needed to open the position (1 ÷ leverage of its value; 10% at 10x).
- Maintenance margin — the minimum collateral needed to keep it open, typically a small percentage of position size that rises in tiers for larger positions. Exchanges publish these tiers.
- Mark price — a fair-value price, usually built from several spot exchanges, that most venues use to trigger liquidations so a single spike on one order book does not wipe people out.
- Liquidation price — the mark price at which your margin balance hits the maintenance level and the engine takes over.
Crypto rarely gives a traditional margin call with time to top up. Exchanges may send warnings as your margin ratio climbs, but once the liquidation price is reached, the system closes the position immediately, often charging a liquidation fee on top.
What happens after a liquidation triggers?
The engine sells (for a long) or buys back (for a short) your position in the market. If it gets a better price than your bankruptcy price (where your margin would be exactly zero), the surplus typically goes to the exchange’s insurance fund. If the market is moving so fast that the position closes at a worse price, the insurance fund absorbs the shortfall. If even that is not enough, many venues use auto-deleveraging (ADL): they forcibly reduce the positions of profitable traders on the other side to balance the books.
How a liquidation price is calculated
Each exchange has its own exact formula, which includes fees and tiered maintenance rates, so always use the liquidation price shown in your trading screen. The simplified version for a USDT-margined position in isolated margin mode is:
- Long: Liquidation price ≈ Entry × (1 − 1/L + MMR)
- Short: Liquidation price ≈ Entry × (1 + 1/L − MMR)
where L is leverage and MMR is the maintenance margin rate as a decimal.
Worked example (illustrative numbers)
Suppose bitcoin trades at $100,000 (a round number chosen for the maths, not a current price). You open a long with $1,000 of margin at 10x, controlling $10,000, or 0.1 BTC. Assume a 0.5% maintenance margin rate.
- 1/L = 1/10 = 0.10
- Liquidation price ≈ 100,000 × (1 − 0.10 + 0.005) = 100,000 × 0.905 = $90,500
- At $90,500, your 0.1 BTC position has lost about $950, leaving roughly $50 of margin, close to the maintenance requirement on a position now worth about $9,050.
A 9.5% drop wipes out 95% of your deposit. The same trade as a 10x short would liquidate near 100,000 × 1.095 = $109,500.
Leverage changes the picture dramatically:
| Leverage (long, entry $100,000, 0.5% MMR) | Approx. liquidation price | Price drop to liquidation |
|---|---|---|
| 2x | $50,500 | about 49.5% |
| 5x | $80,500 | about 19.5% |
| 10x | $90,500 | about 9.5% |
| 20x | $95,500 | about 4.5% |
| 50x | $98,500 | about 1.5% |
| 100x | $99,500 | about 0.5% |
At 100x, an ordinary minute of volatility can close the position. Bitcoin has moved more than 0.5% within a minute many times.
Isolated vs cross margin
Your margin mode decides how much of your account is at risk. Our guide to crypto margin trading covers account setup; here is how each mode behaves at liquidation.
| Feature | Isolated margin | Cross margin |
|---|---|---|
| Collateral at risk | Only the margin assigned to that position | Your whole margin balance (available funds back every position) |
| Liquidation price | Closer to entry; fixed by assigned margin | Further away, because spare balance absorbs losses |
| Worst case | Lose that position’s margin | Lose the entire account balance |
| Can you add margin? | Yes, manually, to move liquidation price away | Automatic: all free balance is already used |
| Best for | Defined risk per trade; beginners | Hedged books and experienced traders managing several positions |
Cross margin can feel safer because liquidation is further away, but if one position goes badly it can drag everything else down with it.
DeFi liquidation: health factor instead of leverage
Lending protocols such as Aave liquidate differently. You deposit collateral and borrow against it, and the protocol tracks a health factor: roughly, collateral value × liquidation threshold ÷ debt. When it falls below 1, anyone (usually automated bots) can repay part of your debt and claim some of your collateral plus a liquidation bonus. There is no exchange or insurance fund in the middle, and prices come from oracles. Our walkthrough of how to borrow on Aave shows the health factor in practice.
Liquidation cascades: October 2025
A liquidation is a forced market order. When many leveraged traders sit near similar prices, one wave of liquidations pushes the price further, triggering the next wave. That chain reaction is a liquidation cascade.
The largest on record came on 10–11 October 2025. After the US president threatened 100% tariffs on Chinese imports late on Friday 10 October, crypto prices fell sharply into thin weekend liquidity. According to CoinGlass, more than $19 billion of leveraged positions were liquidated within roughly 24 hours, the vast majority of them longs, far exceeding any previous day. CoinGlass itself suggested the true total was likely higher, since not every exchange reports liquidations in real time.
Several features of the day are worth learning from:
- Altcoins fell much further than bitcoin. Thin order books meant some tokens briefly dropped far more than the majors, liquidating positions that looked comfortably margined.
- Collateral pricing broke down on one venue. Binance later said it would compensate users, reported at about $283 million, after some collateral assets were mispriced during the crash, causing liquidations that should not have happened.
- ADL hit winners too. On Hyperliquid, a leading on-chain perpetuals venue, cross-margin auto-deleveraging was reported to have activated for the first time, closing profitable positions on the other side when liquidations could not clear normally. If you trade on a perp DEX, read its ADL rules.
The lesson is that a liquidation price is not a guaranteed exit. In a cascade, prices gap, order books empty and even hedged traders can be caught by mechanics they never considered.
How to avoid being liquidated
- Use less leverage. The single most effective step. At 2–3x, it takes a very large move to liquidate you; at 25x or more, normal noise can do it.
- Place a stop-loss above your liquidation price. A stop lets you choose a smaller, planned loss instead of handing the position to the engine and paying a liquidation fee. Our guide on how to set a stop-loss covers order types. In fast markets stops can fill at worse prices (slippage), so leave room.
- Prefer isolated margin while learning, so one bad trade cannot drain your account.
- Size positions from the stop, not from leverage. Decide the maximum you are prepared to lose (for example 1–2% of your account), set the stop, then size the position to match.
- Watch funding, weekends and news. Liquidity thins outside major market hours and around macro announcements, which is when cascades tend to start.
- Keep spare collateral off the exchange and top up isolated margin deliberately rather than relying on cross margin to save a losing trade.
- In DeFi, keep a buffer. Keep the health factor well above 1 and set alerts, remembering that oracle prices and gas spikes can make last-minute repayments difficult.

FAQ
What does liquidation price mean?
The liquidation price is the mark price at which an exchange will automatically close your leveraged position because your remaining margin has fallen to the maintenance requirement. It depends on entry price, leverage, maintenance margin rate, fees and, in cross margin, your free balance. Your trading screen shows it for each open position, and it moves if you add or remove margin.
Do you lose all your money when liquidated?
In isolated margin you usually lose most or all of the margin assigned to that position, plus a liquidation fee, but not the rest of your account. In cross margin, a liquidation can consume your entire margin balance. On most major crypto derivatives venues you do not end up owing more than your deposit, because insurance funds and auto-deleveraging are designed to cover the gap; check your platform’s terms.
Is a margin call the same as liquidation in crypto?
Not quite. A margin call is a warning that your collateral is running low; liquidation is the forced closure that follows if you do not act. Many crypto exchanges send margin-ratio alerts, but there is rarely a grace period: once the liquidation price is hit, closure is automatic and immediate, so you need to add margin or reduce the position before that point.
How is DeFi liquidation different from exchange liquidation?
DeFi liquidation is triggered by a health factor falling below 1 on a lending protocol rather than by a futures margin ratio. Independent liquidators, usually bots, repay part of the loan and take collateral at a discount set by the protocol. Prices come from on-chain oracles, there is no customer-support desk, and transactions compete for block space, which can be costly during market stress.
