Global equity markets opened higher on Thursday, buoyed by sharp gains in U.S. futures after a landmark federal court ruling blocked former President Donald Trump’s authority to impose trade tariffs. The move was viewed as a significant de-escalation of trade-related risks, further supported by strong quarterly results from artificial intelligence major Nvidia.

A U.S. federal court ruled that Donald Trump did not have the authority to set tariffs unilaterally, effectively blocking the so-called “Liberation Day” tariffs introduced during his presidency. The Trump administration has already appealed the decision. The White House issued a sharp response, stating, “It’s not for unelected judges to decide how to properly address a national emergency.”

This legal development was interpreted by markets as a rollback of protectionist trade policies, leading to a relief rally in equities. U.S. stock index futures surged in response:

  • Dow Futures jumped 500 points (+1.19%) to 42,599

  • Nasdaq Futures gained 400 points (+1.88%) to 21,718

  • Russell 2000 Futures rose 41 points (+1.98%) to 2,109

The positive momentum spilled over into global markets:

  • Germany’s DAX Futures were up 190 points (+0.79%)

  • UK’s FTSE Futures added 62 points (+0.70%)

  • Japan’s Nikkei Index gained 529 points (+1.40%) to 38,252

  • South Korea’s KOSPI rose 30 points (+1.14%)

  • Taiwan’s Taiex Futures climbed 141 points (+0.67%)

India’s GIFT Nifty was up 57 points (+0.23%) at 24,820 (adjusted). However, Hang Seng Futures in Hong Kong edged slightly lower by 24 points (-0.10%).

This rebound comes after a slightly negative close on Wall Street on the previous day:

  • Dow Jones closed at 42,099, down 245 points (-0.58%)

  • Nasdaq ended at 19,101, lower by 98 points (-0.51%)

Analysts noted that the combination of strong AI earnings and legal checks on unilateral tariff powers has infused fresh optimism across equity markets globally.
