Aave USDC Liquidity Crisis Spurs Urgent Interest Rate Proposal from Circle Economist

Circle’s Chief Economist Gordon Liao has introduced a proposal to recalibrate Aave’s USD Coin (USDC) interest rate model, aiming to resolve the ongoing liquidity crunch on Aave v3 Ethereum. The proposal comes after USDC utilization surged to nearly 100%, leaving less than $3 million in available liquidity and triggering concerns across the decentralized finance (DeFi) market.

The liquidity shortage began following the April 18 exploit involving KelpDAO’s rsETH, which led to approximately $300 million in additional borrowing activity. As a result, USDC pools on Aave became heavily utilized, with utilization rates hitting 99.87% for several consecutive days. At the same time, total USDC supply on the platform dropped by about $60 million within 24 hours, intensifying the imbalance.

Liao’s analysis highlights that many users are borrowing stablecoins against their own deposits to exit positions through decentralized exchanges. These borrowers are considered relatively insensitive to interest rates, meaning the current borrowing costs are too low to discourage activity or attract new liquidity providers. Even at a 14% rate, the short-term cost remains minimal, reducing the effectiveness of the existing model.

To address this, Liao proposed a two-step adjustment to Aave’s interest rate parameters. The first phase includes an immediate Risk Steward action to increase Slope 2 to 40% and reduce optimal utilization to 87%. A follow-up governance vote within a week could push Slope 2 further to 50%, potentially raising supply rates to around 48%. This sharp increase is expected to attract capital back into the protocol quickly and restore healthier utilization levels.

Circle CEO Jeremy Allaire publicly supported the proposal, while Aave founder Stani Kulechov confirmed that the team is actively working on multiple solutions. Meanwhile, the recovery of $70 million in ETH by the Arbitrum Security Council may help ease market pressure.

Despite the turbulence, AAVE token price has risen 5% in the past 24 hours, signaling cautious optimism among investors as the DeFi platform moves toward stabilization.
