Aave V3’s risk management has been highlighted in a recent Bank of Canada study, showing how the platform successfully avoided bad debt by transferring risk to borrowers. The study revealed that Aave V3 reported zero non-performing loans in 2024, largely due to its unique overcollateralization model and automated liquidations that protect lenders from losses in Ethereum’s lending market.
Understanding Aave V3’s Risk Management Model
The research, using transaction data from January 27, 2023, to May 6, 2025, found that Aave’s system efficiently liquidated positions before collateral values fell below the outstanding debt. This strategy effectively minimized lender losses across the board. However, the approach involves a trade-off, as it shifts risk onto borrowers and limits capital efficiency compared to traditional lending systems.
Aave V3’s design relies on automated risk controls, requiring borrowers to provide more collateral than they borrow. These positions are liquidated when they breach predetermined risk thresholds, ensuring that lenders are shielded from unrecovered losses.
Recursive Leverage and Its Impact
The study also identified that Aave V3’s lending activity wasn’t solely driven by liquidity needs. Recursive leverage, a process where borrowers repeatedly use borrowed assets as new collateral to amplify exposure, accounted for over 20% of total borrowed volume and 8.2% of borrowing transactions during the study period.
This leverage strategy made borrowers more vulnerable during market downturns. Liquidations on Aave V3 often occurred in concentrated waves, primarily involving four assets: Wrapped Ether (WETH), Wrapped Staked Ether (wstETH), Wrapped Bitcoin (WBTC), and Wrapped eETH (weETH).
Implications for Borrowers
The paper pointed out that borrower losses during major liquidation events could be significant. Liquidation fees typically ranged from 5% to 10% of the liquidated value, with missed gains from subsequent price recoveries pushing combined losses to 10% to 30% in some cases. While Aave V3’s design helps prevent bad debt, it exposes borrowers to potential abrupt losses when collateral prices fall sharply.
Cointelegraph reached out to Aave for comments but did not receive a response by publication time.
