DeFi's Credit Risk Repriced in Just 48 Hours

Until April 17, lending stablecoins on Aave yielded 2.32% APY, lower than the Federal Reserve's overnight rate of 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 was corrected within 48 hours. The market's repricing of DeFi credit risk was triggered by an exploit on Kelp DAO's cross-chain bridge, which allowed an attacker to mint unbacked tokens and borrow against them on Aave. The resulting contagion led to $6-10 billion in net outflows from Aave, causing utilization on certain pools to reach 100% and depositors to be unable to withdraw their funds. Rates responded accordingly, with Aave's stablecoin deposit APYs increasing from 3-6% to 13.4% within two days. The incident highlights the lack of bankruptcy law and recourse in DeFi protocols, making it essential for allocators to understand the risks involved. DeFi is not going away, but the market has now adjusted to reflect the underlying risks, and institutional allocators should take this signal seriously when sizing their exposure for the coming year.
