Liquidation: How an Exchange Wipes Out Your Entire Position in Seconds

"Bitcoin dropped 2.5%, $400M in liquidations" — headlines like this show up in crypto news almost every week, including our own coverage of the recent bitcoin drop on Asian-session liquidations. Here's what's actually happening behind that phrase.

What liquidation actually means

Liquidation is when an exchange force-closes a trader's position — one opened with borrowed funds (leverage) — because the loss on the trade is approaching the size of the collateral put up. The exchange closes it automatically, without asking the trader, to avoid being left with an uncovered debt.

Why one liquidation drags others down with it

The problem is scale: when an exchange force-sells the assets behind a liquidated position, it pushes the price down further — which can trigger liquidations of other, less risky positions sitting just above their own liquidation threshold. That's how a cascade forms: one price move sets off a wave of automatic sales that pushes the price even further in the same direction. That's why even a fairly minor piece of news can knock a few percent off the market in minutes — the effect isn't really from the news itself, but from the chain reaction of liquidations it triggered.

What to watch for

If you trade with leverage, the key number is your position's liquidation price — the level at which the exchange will automatically close it. The higher your leverage, the closer that price sits to the current market price, meaning the market needs to move against you by less before you lose the whole position. If you're just following market news, a sharp spike in liquidation volume (usually tracked on exchange aggregator sites) is a good sign that a price move is largely technical rather than fundamental.
