Aave's Zero Bad Debt Streak: Lenders Pop Champagne, Borrowers Check If They're Still Breathing

A Bank of Canada staff paper dropped a surprisingly wholesome report card for Aave V3: zero non-performing loans throughout 2024. The decentralized lending protocol kept its lenders pristine, thanks to good old-fashioned overcollateralization and robots (read: automated liquidations) doing the dirty work before anyone could say "rug pull."

The research pulled transaction data from Jan. 27, 2023, to May 6, 2025, and found that positions typically got liquidated before collateral values decided to ghost the outstanding debt. Lenders: absolutely thriving. The paper noted the setup was, in technical terms, "clean."

But here's the catch that would make any Econ 101 professor nod knowingly. While the design kept lenders' loss records cleaner than a degens' browser history, it essentially shoved the risk into borrowers' laps and threw capital efficiency out the window. Traditional finance uses underwriting; Aave uses vibes and math. Both approaches have tradeoffs, but only one comes with a Discord server.

Aave V3 operates on what can generously be called "trustless risk management." Borrowers must overcollateralize positions—meaning you gotta put in more than you borrow, because apparently the protocol learned from every movie where someone says "trust me bro." When positions breach risk thresholds, automated liquidations kick in faster than a bear market turns bulls into叫.

Recursive leverage: the gift that keeps on giving (until it doesn't)

Not everyone's Aave experience was a sober liquidity-seeking endeavor. Recursive leverage—which is crypto-speak for "borrowing against your borrowed assets like a financial Inception"—accounted for over 20% of total borrowed volume and 8.2% of borrowing transactions during the sample period.

The strategy involves repeatedly borrowing against collateral, deploying those funds as fresh collateral, and borrowing again. Rinse, repeat, and watch your exposure multiply like rabbits. It's the DeFi equivalent of building a house of cards during an earthquake. Extremely satisfying when markets moon. Significantly less fun when they don't.

Liquidations hit in concentrated waves, because apparently protocols enjoy dramatic timing. Four assets represented 90% of total liquidated value: Wrapped Ether (WETH), Wrapped Staked Ether (wstETH), Wrapped Bitcoin (WBTC), and Wrapped eETH (weETH). If you were holding any of these in a leveraged position during volatility, congratulations—you were part of the 90%.

Borrower losses during these liquidation events could generously be described as "substantial." Liquidation fees typically ran 5% to 10% of liquidated value—think of it as a convenience fee for having your position force-closed. Add in the missed gains from price recoveries (because of course the asset bounced back right after you got rekt), and total losses hit roughly 10% to 30% in some cases. Nothing a good night's sleep won't fix. (Narrator: it didn't.)
