U.S. stock market has best day since Iran war began

U.S. stock markets surged to their best performance since the Iran war began, driven by a significant drop in oil prices. The rally reflects investor relief as lower energy costs reduce concerns about inflation and economic pressures that typically accompany geopolitical conflicts. Falling oil prices often boost market sentiment because they signal reduced input costs for businesses and lower consumer prices at the pump. The strong trading day suggests markets are interpreting recent developments as potentially easing tensions or supply disruptions that initially drove oil prices higher.
