Aave has lowered the utilization threshold for Tether USDT lending rates on its Ethereum core market, causing borrowing costs to rise sooner when liquidity tightens. This adjustment, executed on October 21 at Ethereum block 26,241,799, reduced the threshold from 94% to 92%. For example, at 94% utilization, the annual borrowing interest rate would increase from 4.5% to 7%. For a 1 million USDT loan, this translates to an additional 25,000 USDT in interest annually.
