Circle’s Gordon Liao proposed deeper Aave V3 USDC parameter changes, including a higher borrow cap target and lower optimal utilization, as elevated rsETH-linked demand continued to strain Ethereum Core pool liquidity.

Fact Check
The claim is strongly supported by the primary source, [ARFC] Improve Liquidity Buffer for USDC on Aave v3 Ethereum Core – Raise Slope 2, Lower Optimal Utilization. That post explicitly says USDC utilization on Aave v3 Ethereum Core was about 99.87% for four days, pool supply contracted by about $60M in 24 hours, and recommends interim Risk Steward action followed by full governance ratification within a week. The secondary reports from Odaily, PANews, and CoinPost consistently describe the same proposal and timeline. One nuance: the primary source is on Aave's governance forum rather than Circle's own website or X account, but the reporting consistently attributes it to Circle chief economist Gordon Liao.

Summary
Circle chief economist Gordon Liao filed a new Aave V3 governance proposal seeking sharper changes to the Ethereum Core USDC market as a liquidity crunch persisted. The proposal calls for pushing the USDC borrow cap toward 50% and lowering optimal utilization, with the aim of driving borrowing costs higher and attracting fresh supply to ease congestion tied to rsETH-driven demand. This builds on Circle’s earlier emergency push after USDC utilization stayed near 100% and supply dropped by about $60 million in 24 hours.
