Global shares slide as tech stocks sink, Nasdaq futures drop over 2.5%

Global markets fell on Tuesday as technology stocks led declines, with Nasdaq futures down more than 2.5% and SpaceX extending premarket losses. Meta, Alphabet and Microsoft also slid, while major European and Asian indexes weakened and South Korea’s KOSPI posted a 10% one-day plunge. U.S. Treasury yields rose to elevated levels as markets nearly fully priced a September rate hike, pushing the dollar index to a one-year high. Brent crude stayed below $80 a barrel, but the policy impact of energy prices continued to weigh on risk assets.
