Aave Loans on Thin Ice as Health Factor Hits Critical Levels

Aave's health factor is a crucial metric that determines whether a loan becomes eligible for liquidation. When it reaches 1.0, the borrower is on shaky ground, and even small price movements can trigger partial liquidation. This is not a warning sign, but rather how Aave's protocol works.

The health factor is essentially a safety ratio that compares the value of collateral to the borrowed amount. It takes into account each asset's risk settings and market parameters. If an asset has high volatility, it will give the borrower less room for error. Conversely, stablecoins in correlated mode can allow for higher effective thresholds.

There are three main reasons why a health factor moves: price changes on collateral or debt, interest accruing on borrowed amounts, and protocol parameter updates. The first two happen frequently, while the third is more rare but can still have significant effects.

A recent analysis of Aave V3 found that several large wallets were running stablecoin strategies with thin buffers, hovering around 1.03 health factor. This is not a sustainable position, as even minor price movements or oracle updates can push the borrower below the liquidation threshold.
