The lending of stablecoins into Aave, a gold standard in DeFi, previously yielded 2.32% APY, lower than the Federal Reserve's overnight rate of 3.64%. This disparity suggested the market viewed DeFi as a lower credit risk than the US Treasury.
However, this changed dramatically over 48 hours, as the market repriced DeFi credit risk in real-time, a feat no regulator, auditor, or commentator had achieved. The mispricing was evident when comparing yields across different dollar-credit options, with Aave's rate being significantly lower than others, such as Treasury overnight, Ledn's investment-grade Bitcoin-backed ABS, and US credit cards. The market correction was triggered by an exploit on Kelp DAO's cross-chain bridge, which led to a liquidity crisis in Aave, resulting in $6-10 billion in net outflows and a significant increase in stablecoin deposit APYs.
The incident highlighted the lack of bankruptcy law and recourse in DeFi protocols, making risk sizing challenging. The market adjustment serves as a reminder that DeFi is not risk-free and carries a premium over regulated equivalents. Institutional allocators should take this signal seriously when sizing DeFi exposure for the coming year.
