A Liquidation Cascade is a reinforcing feedback loop between price movements, insufficient collateral and trades forced by a liquidation mechanism. It can amplify either a decline or a rise, but it does not automatically explain every sharp move or signal its end.
A Liquidation Cascade occurs when an adverse price change triggers forced position closures and the price impact of those trades activates further liquidations. Coin Metrics describes this reinforcing mechanism in crypto futures. A fast price move or a high liquidation total alone does not establish that this feedback caused the entire move. The initial impulse must be distinguished from its subsequent amplification. [1]
Closing a simple long futures position requires an opposite sell trade; closing a short requires a buy. Forced sales can therefore amplify declines, and forced purchases can amplify rises. This does not mean every derivative closure directly sells or buys spot bitcoin. Transmission between derivatives and spot depends on the market, hedging and arbitrage. Coin Metrics distinguishes both sides of liquidations and their potential impact on spot. [1]
Liquidation decisions depend on account valuation and the particular platform's margin model. Deribit's documentation explains that it derives account equity from Mark Price, rather than simply the last trade. An extreme candle alone therefore does not determine which accounts must have been closed. Distinguish the price used in the risk calculation, the trigger time and the actual execution prices of liquidation trades. [3]
In a collateralized loan, a collateral shortfall can arise from falling collateral value or rising debt value. IMF describes this distinction for DeFi loans; it is not the same accounting mechanism as every futures contract. If the asset being sold also secures other accounts, its lower price may weaken their buffers too. The currency of debt and collateral and the valuation method therefore belong in the analysis. [4]
A forced trade needs a counterparty. With less depth, the same quantity may consume more price levels; new orders or cancellations of existing orders change the path. A study published by BIS examines collateral liquidations on Compound and Aave and subsequent price impact on decentralized and other markets. It is a specific empirical DeFi sample, not an estimate of impact size for any bitcoin exchange. [2]
Rules differ by platform and account type. Deribit describes incremental position reductions that stop once requirements are sufficiently covered again. In some portfolio accounts, the system may also adjust risk with hedging trades. A single sale of the entire position therefore cannot be assumed. A slowdown in a cascade depends on remaining risk, available liquidity and the specific rules. [5]
Coin Metrics distinguishes market, time, amount and buy or sell side in liquidation data. The type field distinguishes an executed trade (trade) from a submitted order (order), which may not yet have executed; an order record therefore cannot automatically count as a completed liquidation. For an executed trade, the execution price is given. Such trades' notional volume is not itself traders' accounting loss. CoinGlass, by contrast, describes its heatmap as a calculation of potential concentrations using market data and leverage; the indicator is relative and actual volumes may differ. Such a map is neither a list of confirmed future trades nor a guarantee that price will reach a colored area. [6] [7]
In its international derivatives rules, Coinbase warns of worse liquidation prices, fees and possible losses exceeding margin value. These specific rules cannot be presented as a uniform standard across exchanges. When evaluating a scenario, record references, liquidity, account coverage and the closure process. A completed liquidation wave alone is not evidence of a market bottom, top or future reversal. [8]

01Must every series of liquidations create a cascade?+
No. What matters is whether the price impact activates further undercollateralized positions. Available counterparties, added funds or partial closures can weaken this link; the liquidation count alone does not establish the cause.
02Does a heatmap show exact future liquidations?+
No. Estimates of potential zones depend on methodology and inputs. Account conditions, collateral and positions change. A map must be distinguished from records of completed trades and cannot promise that a particular price will be reached.
