US stock futures edged lower Monday after President Donald Trump said over the weekend that he plans to raise global tariffs from 10% to 15%, following a Supreme Court decision striking down his “reciprocal” tariff policy. Trump indicated the higher duties would take effect immediately, though it remains unclear whether he has formally signed the necessary order. Concerns also mounted that the administration could consider military action against Iran as nuclear negotiations remain stalled, although talks are scheduled to resume in Geneva on Thursday. On Friday, major indexes finished higher in a volatile session after the Supreme Court of the United States blocked Trump’s emergency tariffs. The Dow rose 0.47%, the S&P 500 gained 0.69%, and the Nasdaq Composite climbed 0.9%. All three benchmarks also posted modest gains for the week. Looking ahead, investors will focus on Nvidia’s earnings this week, providing fresh cues on the strength of the artificial intelligence sector.
