Crypto liquidation

Liquidation is the automatic closure or reduction of a leveraged or collateralized crypto position when its margin or health requirements are no longer met. This entry explains mark prices, maintenance margin, health factors, liquidation bonuses, and the risks that remain after a position is liquidated.

Direct answer

Crypto liquidation is the automatic closure or reduction of a leveraged derivatives position or a collateralized borrowing position after the account no longer meets the platform or protocol’s risk requirement. It is a risk-control process, not a prediction that the asset has reached zero.

The trigger differs by product. A centralized derivatives venue generally compares account equity with maintenance margin and may use a mark price. A DeFi lending protocol generally compares collateral value with debt through a health factor and lets an eligible liquidator repay debt in exchange for collateral and a bonus.

Liquidation can crystallize losses, consume collateral, and create execution costs even when a chart’s last traded price does not appear to have reached the displayed liquidation price. The exact trigger, close-out method, insurance arrangements, and possibility of further liability come from the venue or protocol rules.

  • What account or position metric actually triggers the process?

  • Is the position isolated, cross-margined, or backed by shared collateral?

  • Which price source, oracle, fees, and maintenance-margin tier are used?

  • What happens to remaining collateral, bad debt, and the counterparty after execution?

  • What evidence would show that the liquidation rule was applied as documented?

How it works

Centralized derivatives.

A derivatives venue requires initial margin to open a position and maintenance margin to keep it open. When losses and fees reduce equity to the maintenance requirement, the liquidation engine takes control. Many venues use a mark price rather than the last traded price to reduce the effect of an isolated trade or manipulation. The displayed liquidation price is therefore a moving estimate, especially in cross-margin or portfolio-margin mode.

The engine may cancel orders, move the position to a lower risk tier, or partially close it before closing the remainder. If execution is worse than the bankruptcy price, an insurance fund or an auto-deleveraging rule may absorb or redistribute the shortfall, depending on the venue. These are venue-specific safeguards, not universal properties of crypto markets.

DeFi lending.

In an overcollateralized lending protocol such as Aave, the health factor compares collateral value, liquidation thresholds, and outstanding debt. A position becomes eligible for liquidation when its health factor falls below 1. A permissionless liquidator repays an allowed portion of the debt and receives collateral plus a liquidation bonus; protocol parameters determine whether the position is partially or fully cleared.

The health factor changes as oracle prices, debt balances, collateral balances, and governance parameters change. Liquidation transactions also compete for block inclusion and pay network fees, so an eligible position may experience slippage or bad debt before a transaction settles.

What the liquidation price means.

The liquidation price is a rule-dependent threshold, not a guaranteed execution price. It can change after adding or removing margin, changing position size, accruing funding or interest, crossing a risk tier, or moving the reference price. A stop order tied to a different price source may trigger after liquidation, and an isolated position’s loss limit does not imply that every product limits losses to the initial margin.

Worked example

A trader posts 2,000 USDT and opens a 20,000 USDT BTC long with 10x leverage. A 5% adverse move produces an unrealized loss of about 1,000 USDT before fees, funding, and maintenance-margin effects. Because those additional amounts reduce equity, liquidation can occur before a simple 10% loss calculation, and the actual threshold depends on the venue’s rules and mark price.

The same arithmetic does not describe an Aave-style loan: there, the relevant question is whether collateral value divided by debt, after the protocol’s liquidation threshold, leaves a health factor above 1. Comparing a derivatives liquidation price with a DeFi health factor without checking the product type is a category error.

Risks

  • Do I know the precise trigger and price source for this product?

  • Could gaps, thin liquidity, slippage, fees, or network congestion worsen execution?

  • Can the venue use partial liquidation, an insurance fund, or auto-deleveraging?

  • Could protocol, oracle, smart-contract, custody, or counterparty failure leave bad debt?

Crypto assets are highly volatile and blockchain transactions are generally irreversible. Leverage can magnify losses, and the CFTC warns that margin trading can require additional funds or result in losses greater than the initial amount. Read the venue or protocol documentation before treating a displayed liquidation price or health factor as a guarantee.

Common misconceptions

Misconception 1: Liquidation means the asset went to zero

Liquidation usually means a particular account or position failed a risk rule. The underlying asset may still be trading normally.

Misconception 2: The chart’s last price is always the trigger

Many derivatives venues use a mark price, and DeFi protocols use oracle prices. A last traded price or a wallet app’s spot quote may not be the value that triggers liquidation.

Misconception 3: Leverage alone determines the threshold

Entry price, direction, position size, margin mode, maintenance tier, fees, funding, interest, collateral quality, and protocol parameters can all change the result.

Misconception 4: Liquidation ends every liability

A platform may limit losses, but gaps, borrowing terms, insurance rules, or insolvency arrangements can leave a shortfall. Liquidation is an execution event, not a promise that no further loss is possible.
