Ethereum (ETH) has returned above $1,600, with AI concept tokens leading the rise by over 15%. This rebound is mainly driven by favorable policy news, enhanced liquidity expectations, and the linkage effect of tech stocks. The Trump administration announced a suspension of tariff increases, easing market concerns over trade conflicts and improving risk appetite. At the same time, the market expects global central banks to maintain loose policies, with the Federal Reserve potentially restarting 'money printing' to support the economy and inject liquidity into the crypto market. Additionally, the recovery of the US tech sector boosts market sentiment, leading to a simultaneous rise in crypto-related stocks, reinforcing confidence in capital inflows.
