DeFi's 48-Hour Repricing: A Market Correction

Until April 17, lending stablecoins on Aave yielded 2.32% APY, lower than the Federal Reserve's overnight rate of 3.64%. This mispricing was corrected within 48 hours after an attacker exploited Kelp DAO's cross-chain bridge, minting unbacked tokens and borrowing against them on Aave. The incident led to instant contagion, with $6-10 billion in net outflows from Aave and a significant increase in stablecoin deposit APYs. The event highlighted the lack of bankruptcy laws and recourse in DeFi protocols, making risk sizing challenging. DeFi is not risk-free and carries a premium over regulated equivalents. The market correction serves as a reminder for institutional allocators to reassess their DeFi exposure.
