U.S. stock futures declined on Monday after President Donald Trump announced plans to boost global tariffs, responding to a recent Supreme Court decision invalidating parts of his prior trade strategy.

As of 4:50 P.M. (GMT+7), Dow Jones Industrial Average futures fell by 0.26%, or 126.70 points, to 49,499.30 points, while S&P 500 futures slipped by 0.20%, or 13.60 points, to 6,895.90 points. Nasdaq 100 futures also decreased by 0.31%, or 77.10 points, to 24,935.50 points.

The retreat in futures followed a turbulent end to last week’s trading, when the Supreme Court struck down Trump’s reciprocal tariff framework. That ruling initially lifted market sentiment, with traders anticipating a possible pause in escalating trade tensions.
