Major U.S. stock indexes closed about 0.6% lower on Tuesday, as investors grew increasingly concerned that a peace agreement between the United States and Iran would not be reached before the current ceasefire expires on Wednesday. Sentiment worsened after Vice President JD Vance’s trip for talks in Tehran was put on hold amid what officials described as Iran’s lack of commitment.
After the closing bell, however, President Trump extended the U.S. ceasefire with Iran, saying the government in Tehran was “seriously fractured.” He added that the truce will remain in place until Iran’s leaders present a “unified proposal” to end the war.
