What it is

When a leveraged position can no longer meet its maintenance margin, the exchange force-closes it at market. That forced sell (for longs) or buy (for shorts) moves price further in the same direction, which pushes the next cluster of positions past their own liquidation level — and so on. The result is a fast, stair-stepping move.

Why leverage fuels it

Higher aggregate leverage means liquidation levels sit closer together and closer to price, so a small move can chain through many of them. When open interest is high and funding is stretched to one side, the fuel for a cascade is in place — the market is crowded and thinly buffered.

How to read the setup

Cascades are a risk condition, not a prediction. Rising open interest into a stretched funding rate, plus thin resting liquidity where positions cluster, is the classic setup. The cascade itself is visible as a burst of liquidations and a rapid price impulse; the aftermath often flushes leverage and resets funding.
