U.S. stock markets surged on Monday after President Donald Trump announced a five-day delay in military strikes on Iranian power plants, easing fears of immediate conflict amid tensions over the Strait of Hormuz. The announcement led to a sharp decline in oil prices, though crude remains significantly higher than pre-conflict levels, contributing to rising gasoline costs in the U.S. Despite the temporary de-escalation, Iranian officials rejected dialogue with Washington, maintaining a tense diplomatic standoff.
