Aave avoided bad debt by shifting risk to borrowers: Bank of Canada study
A Bank of Canada staff paper found Aave V3 avoided bad debt in 2024, but said the model pushed losses onto borrowers during liquidations.
A Bank of Canada staff paper found that Aave V3 reported zero non-performing loans in 2024, with overcollateralization and automated liquidations helping prevent lender losses in its Ethereum lending market.
Using transaction-level data from Jan. 27, 2023, to May 6, 2025, the study found that positions were typically liquidated before collateral values fell below outstanding debt, helping contain lender losses across the sample.
But the model came with a tradeoff, the paper said. While it protected lenders from unrecovered losses, it also shifted risk onto borrowers and constrained capital efficiency compared with traditional lending systems.
