US stock futures plunged Sunday evening, setting up Wall Street for another bruising day on Monday as markets braced for more fallout from President Trump's fast-moving tariff policy.

Futures tied to the S&P 500 (ES=F) plummeted over 3%, while those on the tech-heavy Nasdaq (NQ=F) lost 4%. Dow Jones Industrial Average futures (YM=F) sank 2.5%, or around 1,000 points. Oil prices also dropped more than 3%, tumbling below $60 per barrel for the first time since 2021.
