What Is a Crypto Liquidation? How Leverage, Margin and Forced Selling Work

A crypto liquidation is a forced closing of a leveraged position. When you trade with borrowed money — through perpetual futures, margin trading or a collateralized loan — the exchange or protocol requires you to keep enough of your own funds posted as a cushion. If losses eat through that cushion past a set threshold, the platform closes your position automatically, often at a loss to you, to protect itself and the other side of the trade. That's the whole concept; the rest of this guide is the mechanics, the vocabulary, and how to read the headline numbers that appear every time the market lurches. It's the hub for our coverage of liquidation waves, and it builds on our Ultimate Guide to Perpetual Futures Markets.

How a liquidation works, step by step

Say you put $1,000 of your own money (your margin) behind a $10,000 long position on bitcoin. That's 10× leverage: the position is ten times the cash you posted. If bitcoin rises 5%, the position gains $500 — a 50% return on your margin. If it falls 5%, you lose $500, half your margin. If it falls about 10%, the loss approaches your entire $1,000. Before that happens, the exchange steps in. Every venue sets a maintenance margin, a minimum cushion below which a position is no longer considered safe, and the price at which you hit it is your liquidation price. Cross it, and the platform's liquidation engine closes the position.

The same logic runs in reverse for a short: a trader betting on a fall posts margin, and a price rise eats it. Longs are liquidated when price falls; shorts when price rises. That asymmetry is why you'll see headlines describing a "long flush" or a "short squeeze" — they're describing which side was forced out.

What the chart is telling you

The chart above is deliberately simple: the adverse move that erases your starting margin is roughly 100 divided by your leverage. At 2×, the price has to move about 50% against you; at 10×, about 10%; at 100×, about 1% — a move bitcoin makes on a quiet day. In practice the threshold is tighter, because exchanges liquidate you before your margin hits zero, and fees and funding payments eat into the cushion as well. The takeaway isn't that leverage is good or bad; it's that the distance between "normal volatility" and "forced exit" shrinks fast as leverage rises.

Isolated vs. cross margin

Most platforms let a trader choose how margin is assigned. With isolated margin, only the margin you allocated to a single position is at risk, and the position is liquidated when that amount is used up. With cross margin, your whole account balance backs your positions, which delays liquidation but means a bad position can draw down funds you weren't thinking about. Some exchanges also run portfolio-margin systems that net offsetting positions and accept a wider range of assets as collateral. The terms differ by venue, so the same price move can liquidate one account and not another.

What the exchange does when it liquidates you

The details vary, but the general sequence is similar. First, platforms usually trigger liquidations off a mark price — a reference price derived from an index across several markets — rather than the last traded price, so a single thin trade can't set off a wave. Second, the engine closes the position, often with a market order or by passing it to a dedicated liquidation mechanism. Third, if the position is closed at a worse price than the level where your margin would have run out, the shortfall has to be covered; many exchanges maintain an insurance fund for this. If the fund can't cover it, some venues use auto-deleveraging (ADL), closing profitable opposing positions to balance the book. Whether you receive any leftover margin back after a liquidation, and what fee applies, depends on the exchange.

Why liquidations cascade

A liquidation isn't just an outcome of a price move; it's also an input. Closing a leveraged long means selling into the market, which pushes the price down, which can trigger the next group of liquidations, which means more forced selling. Traders call that chain reaction a liquidation cascade. It runs in the other direction in a short squeeze: forced buying by liquidated shorts pushes price up and liquidates more shorts. Crypto trades around the clock on venues that allow high leverage, which is why cascades can be sharp. We trace two recent examples in Inside the $648 Million Short Squeeze and the $86K–$87K squeeze, and the dynamics of momentum and forced flows in The Anatomy of a Pump.

Reading a liquidation headline without getting fooled

Liquidation totals are among the most quoted — and least standardized — numbers in crypto. This week's coverage shows why. CoinDesk reported about $550 million liquidated on one day, per CoinGlass, in its Oct. 8 report on bitcoin breaking below $83,000. A day later, it reported a $1.19 billion 24-hour total from an unnamed source, and the per-asset figures listed in the same article added up to about $903 million, not $1.19 billion (see Ether Traders Were Liquidated at Six Times Bitcoin's Rate). Without implying any of those are wrong, here's what commonly drives gaps like that:

• Time window. "Yesterday," "24 hours," "four hours" and "since midnight UTC" produce different totals for the same market move.
• Venue coverage. A tracker may include some centralized exchanges and decentralized venues like Hyperliquid and exclude others.
• Data feeds. Some exchanges publish liquidation data as sampled snapshots rather than a complete record, so a tracker built on them may understate the true total.
• Counting method. Totals can be reported in notional position size or in some other measure, and may or may not include partial liquidations.

The practical rule: compare numbers from the same provider and the same window, and treat a total with no named source as a rough indicator.

Normalizing: why "six times" can beat a bigger raw number

Raw dollars favor big assets, so analysts sometimes scale liquidations by market value or open interest. In its Oct. 9 report, CoinDesk calculated that ether was liquidated at about $1.2 million per $1 billion of market value versus about $180,000 for bitcoin — roughly six times the rate — even though bitcoin's raw dollar figure ($298 million) was close to ether's ($356 million). The source didn't give an ETH-specific cause for the gap, and neither do we. The point is that a smaller asset with a similar amount of leverage in it gets hit proportionally harder.

Open interest, funding rates and "crowded" trades

Open interest (OI) is the total value of outstanding derivative contracts that haven't been closed. Rising OI during a price move means new positions are being added, not just old ones closed. Funding rate is a periodic payment between longs and shorts in perpetual futures that nudges the contract's price toward the spot price: when the rate is positive, longs pay shorts, which often signals that more traders are positioned long. Long/short ratios are another gauge. None of these predicts a liquidation event on its own, and each is calculated differently by different providers. They're best read together, as clues to how much leverage is in the system rather than as signals of direction. (CoinDesk's Oct. 9 report didn't publish OI or funding data; it noted only that traders had built up leverage while bitcoin ranged between about $83,000 and $87,000.)

Liquidation heatmaps: models, not data

You'll often see a "liquidation heatmap" showing price levels where lots of positions might be forced out. These are modeled estimates: the vendor combines open interest with assumptions about typical leverage and entry prices to guess where liquidations cluster. They can be useful for thinking about where forced flows might appear, but they aren't a record of actual positions, vendors' models disagree, and a price level reported in a social post is only as good as the model behind it. That's why PumpReport doesn't print a specific "next cluster" level unless a named source publishes one we can attribute.

Liquidations outside perpetual futures

The same logic applies wherever borrowed money or posted collateral is involved. In DeFi lending protocols, a loan is liquidated when the value of the collateral falls below a set ratio, usually with a penalty paid to whoever carries out the liquidation. On centralized exchanges, collateral can include assets beyond crypto: this week, Binance began accepting tokenized stocks as margin collateral in permitted jurisdictions, though CoinScoop reports borrowing against them is not available at launch (see our report). Whenever the thing backing a position can fall in value, a liquidation mechanism exists to cover it.

The record that frames every liquidation conversation

CoinDesk notes that on Oct. 10, 2025, a record $19 billion was liquidated in a single day — about 16 times the $1.19 billion it reported for this week's 24-hour flush. A year later, that day remains the reference point for what a full-scale deleveraging looks like, and the reason liquidation data gets so much attention.

Risk concepts traders commonly use

For context, not as advice: traders who use leverage commonly rely on a few concepts. Lower leverage widens the distance to the liquidation price. Isolated margin limits how much a single position can lose. Position size relative to account size limits damage from any one trade. Stop orders attempt to exit before a liquidation price, though they can slip in fast markets. And understanding a venue's own rules — how it calculates mark price, what its liquidation fee is, and whether it uses ADL — matters as much as any strategy. None of this guarantees any result; leveraged trading can lose more than a trader expects, and many participants lose money.

Fast answers

What is a crypto liquidation?

A crypto liquidation is the forced closing of a leveraged position by an exchange or protocol when the trader's margin falls below the required maintenance level. It is triggered automatically, usually at a loss to the trader, to protect the platform and the other side of the trade.

What is a liquidation price?

The liquidation price is the price at which a leveraged position's remaining margin falls to the exchange's maintenance requirement, triggering a forced close. It depends on leverage, entry price, margin mode (isolated or cross), fees and the exchange's rules, so it differs by venue.

Why do crypto liquidation totals differ between reports?

Reports can use different time windows, cover different exchanges and decentralized venues, rely on sampled data feeds, or count in different ways. For example, CoinDesk reported about $550 million per CoinGlass for one day and $1.19 billion over 24 hours from an unnamed source a day later, and its per-asset figures summed to about $903 million.

What is the difference between a long squeeze and a short squeeze?

In a long squeeze or long flush, falling prices force leveraged longs to be liquidated, and their forced selling can push prices lower. In a short squeeze, rising prices force shorts to be liquidated, and their forced buying can push prices higher.

Do you lose everything when you are liquidated?

Usually you lose the margin allocated to the position, and possibly more of your account under cross margin, plus fees. Outcomes differ by venue, and if a position is closed at a worse price than expected the exchange's insurance fund or auto-deleveraging may be involved. Read the venue's rules.
