DeFi's 48-Hour Market Correction

Prior to April 17, lending stablecoins on Aave yielded 2.32% APY, despite the Federal Reserve's overnight rate being 3.64%. This implied that the market viewed an unregulated, open-source smart contract as a lower credit risk than the US Treasury. However, this mispricing ended within 48 hours. The market's repricing of DeFi credit risk was triggered by an exploit on Kelp DAO's cross-chain bridge, which led to a $292 million worth of unbacked rsETH tokens being minted and used as collateral on Aave. The resulting contagion led to $6-10 billion in net outflows from Aave, causing utilization on WETH, USDT, and USDC pools to hit 100%. Depositors were unable to withdraw, and borrowers could not source stablecoin liquidity. Aave's stablecoin deposit APYs surged from 3-6% to 13.4% within two days. The incident highlights the lack of bankruptcy law and recourse within DeFi protocols, making it crucial for institutional allocators to reassess their exposure to DeFi. The market's correction serves as a reminder that DeFi is not risk-free and carries a premium over its regulated equivalents.
