DeFi liquidation occurs when a borrower's collateral is automatically sold by a decentralized finance (DeFi) protocol to repay a loan after its value falls below the required threshold.
What Is DeFi Liquidation?
DeFi liquidation occurs when a borrower’s collateralized assets are automatically sold to repay a loan due to a drop in collateral value. This process happens in DeFi lending protocols, where users borrow crypto assets by locking up collateral. If the collateral’s value falls below a required threshold, the protocol liquidates the position to protect lenders from losses.
Liquidations help maintain the stability of DeFi lending markets by ensuring that loans remain backed by sufficient collateral. However, they can lead to asset loss for borrowers if their positions are forcibly closed due to market volatility.
How Does DeFi Liquidation Work?
-
Collateralized Borrowing: Users deposit assets (e.g., ETH, BTC, or stablecoins) as collateral to borrow funds.
-
Collateral Value Drops: If the market price of the collateral falls below a set liquidation threshold, the position becomes undercollateralized.
-
Automatic Liquidation: The DeFi protocol sells the collateral to repay the loan, ensuring that the system remains solvent.
Many DeFi platforms, including Aave and Compound, use liquidation mechanisms to protect lenders from exposure to bad debt.
Why Does DeFi Liquidation Matter?
-
Risk Management: Borrowers must monitor collateral ratios to avoid forced liquidation.
-
Market Volatility Impact: Sudden price drops can trigger mass liquidations, affecting crypto prices.
-
Opportunities for Liquidators: Some traders profit by participating in liquidation auctions or earning fees for repaying bad debt.
Understanding DeFi liquidation is crucial for borrowers and investors in DeFi lending platforms, as it directly affects risk exposure and capital efficiency in decentralized finance.
