Aave raises USDT borrowing costs earlier to safeguard liquidity
Aave changed borrowing parameters for USDT on its Ethereum V3 Core market, making rates rise sooner once 92% of available liquidity is borrowed, down from 94%. At 94% utilization, the theoretical annual borrowing rate increases from 4.5% to 7%, creating an additional liquidity buffer of about 57.8 million USDT. The DeFi protocol aims to keep more funds available for withdrawals.
Aave’s adjustment took effect on Oct. 21 at Ethereum block 26,241,799. The protocol left the rest of the USDT rate curve unchanged: a zero base, a 4.5% first slope, and a 10% second slope. Borrowing above 92% is not barred; it simply becomes more expensive.
LlamaRisk recommended the change after reviewing roughly $2.89 billion in USDT deposits against $2.48 billion borrowed, a utilization rate near 85.6%. The projected extra $57.8 million cushion is not new funds added by Aave; it would require repayments or fresh deposits to appear.
This change may mainly affect DeFi users who borrow or supply USDT on Aave, as higher rates could discourage heavy borrowing and make withdrawals easier during stress. Stablecoin holders and integrated protocols relying on Aave liquidity could see more predictable access, though borrowers may face higher costs. Broader crypto markets may read such parameter tweaks as risk-management signals, but the direct societal effect is likely limited to participants in decentralized finance.
