Liquidation Cascade
A liquidation cascade is a chain reaction in which the forced closing of leveraged positions moves the price, which triggers more liquidations, which move the price further. It turns an ordinary move into a sharp spike or crash.
How a cascade starts
Every leveraged position has a liquidation price. When the market reaches it, the exchange or protocol closes the position by selling (for a long) or buying (for a short) at market. If many traders used high leverage and their liquidation prices sit close together, a modest move can hit the first group.
Their forced market orders push the price further in the same direction, reaching the next group's liquidation levels. Those closures push it further again. Thin order books, for example on weekends or at night, make each step larger.
Long and short cascades
A long cascade happens in a falling market: forced selling from liquidated longs drives the price down, often called a long squeeze. A short cascade happens in a rising market: forced buying from liquidated shorts drives the price up, a short squeeze. Both leave long wicks on price charts and a sudden drop in open interest, the total value of open derivative positions.
A real example
On 12 March 2020, known as Black Thursday, Bitcoin fell roughly half its value within about a day as global markets panicked over Covid-19. Waves of liquidations on derivatives exchanges and in DeFi lending protocols amplified the drop, and congestion on Ethereum made it hard for some users to add collateral in time.
Why it matters to you
Cascades explain why crypto prices can overshoot far beyond what news alone would justify. If you trade with leverage, you can be swept out by a move that reverses minutes later. Lower leverage, wider margins and sizing positions to a planned maximum loss reduce the chance that someone else's liquidation becomes yours. Liquidation heatmaps try to estimate where clusters sit, but they are estimates, not maps of real orders.

Frequently asked questions
How does a liquidation cascade end?
It ends when the leveraged positions near the price are cleared and enough buyers or sellers step in to absorb the forced orders.
Can a cascade happen in DeFi too?
Yes. When collateral prices fall, lending protocols liquidate loans, and the sold collateral can push prices lower and trigger more liquidations.
Can I predict a liquidation cascade?
Not reliably. High open interest and crowded positioning raise the risk, but the trigger and timing are uncertain.
