Circle has proposed an emergency overhaul of the interest rate parameters on Aave V3 Ethereum Core's USDC pool, which has been pinned at 99.87% utilization for four days in the wake of the April 18 KelpDAO exploit.
In a governance post published Tuesday, Circle Chief Economist Gordon Liao argued Aave's current interest rate mechanism is failing to clear the market. The pool holds $1.89 billion in supply against $1.89 billion in borrows, with less than $3 million in available liquidity. Borrow rates are flat at the post-kink ceiling of roughly 14%, and the pool has contracted about $60 million in the last 24 hours as repayments are matched dollar-for-dollar by queued withdrawals.
Liao's proposal would raise the pool's Slope 2 parameter for USDC deposits interest rate, from roughly 10% to 40% immediately, via a Risk Steward action. That would be followed by governance ratification of a 50% target within five to seven days.
