According to @lookonchain, address 0x540C withdrew 114.9M USDT from Aave, pushing USDT utilization on the core market to 92.83%, above the 92% optimal utilization threshold (source: @lookonchain; source: Etherscan tx 0x8427fc1c91a133c02f10999c089806ebff0296bae4c875f07ed379b649ba8549). According to Aave documentation, when utilization exceeds the optimal level, the kinked interest rate model increases variable borrow APRs sharply and lifts supply APYs due to the higher post-kink slope (source: Aave Docs – Interest Rate Strategy). Based on @lookonchain’s reported 92.83% utilization, USDT borrowing costs on Aave should rise while USDT suppliers see higher yields under the model mechanics (source: @lookonchain; source: Aave Docs – Interest Rate Strategy). For traders, monitoring Aave’s USDT variable borrow APR, supply APY, and available liquidity can inform decisions to repay variable USDT debt or supply USDT to capture elevated yields in line with the documented rate model (source: Aave Docs – Interest Rate Strategy; source: @lookonchain).

According to @EmberCN, HTX withdrew a large amount of USDT from Aave and then redeposited it, causing a sharp, temporary spike in Aave's USDT borrowing rates to around 30% APY before rates normalized to 3.73% for deposits and 5.06% for borrowing. This liquidity fluctuation highlights how major exchange actions can impact DeFi lending rates and arbitrage opportunities for traders. Crypto market participants should monitor on-chain USDT flows on Aave, as such events can create short-term trading opportunities and affect stablecoin yields (Source: @EmberCN, Twitter, June 5, 2025).
