President Donald Trump is scheduled to address the United Nations General Assembly on September 22, 2026, as the US-Iran conflict enters its seventh month without a clear end. He is expected to present the military campaign as a response to nuclear threats while criticizing the United Nations and portraying US leadership as necessary during a period his administration describes as globally tumultuous. The conflict began with US airstrikes in 2025, including a major round in June that Trump has said destroyed Iran’s nuclear capabilities, and has since expanded into military operations, an oil blockade and broader economic pressure. Disruptions around the Strait of Hormuz have kept oil prices elevated and added to global inflation concerns, while Iran’s involvement in regional proxy conflicts, including Houthi activities in the Red Sea, has increased the risks. US Treasury Secretary Scott Bessent said all Iranian airlines would be shut down beginning September 23, one day after Trump’s speech. At the same time, the United States approved visas for a smaller Iranian delegation to attend the General Assembly under strict travel restrictions. Markets are expected to focus on whether Trump signals escalation, negotiations or changes in military strategy, with oil prices particularly sensitive to developments around the conflict.
