Circle initiated a proposal on the Aave forum to raise the maximum deposit interest rate for USDC to 48.2%

Circle Chief Economist Gordon Liao initiated a proposal on the Aave governance forum, suggesting an emergency adjustment to the USDC interest rate parameters in the Aave V3 Ethereum main pool to address the situation where the pool's utilization rate has remained at a very high level of 99.87% for four consecutive days following the KelpDAO attack incident.

Liao stated that Aave's current interest rate mechanism has failed to effectively "clear" the market. The current supply of the pool is $1.89 billion, with the borrowing amount also at $1.89 billion, and available liquidity is less than $3 million. The borrowing interest rate remains at the upper limit after the inflection point (around 14%), and over the past 24 hours, the pool size has shrunk by about $60 million—this is due to repayment funds being used one by one to meet the withdrawal demands in the queue.

Therefore, the Slope 2 parameter in the USDC deposit interest rate curve should be immediately increased from about 10% to 40% through the Risk Steward mechanism, and further confirmation to raise the target to 50% should be achieved through governance voting within 5 to 7 days. Meanwhile, the optimal utilization will be adjusted down from 92% to 87% during the transition phase, and after final confirmation, it will be reduced to 85%. According to Liao's proposal, under the new parameter settings, when the utilization rate reaches 100%, the maximum USDC deposit interest rate will increase from about 12.6% to 48.2%.
