The U.S. Treasury Secretary Scott Bessent says all Iranian airlines will be effectively shut down around the world starting September 23. In remarks reported Monday, he warns that if Iranian aircraft land, service providers would face consequences, including restrictions related to U.S. dollar access.
According to multiple outlets, Bessent frames the move as part of intensified economic pressure on Iran, following earlier U.S. sanctions targeting Iran’s aviation sector. Several reports say the U.S. threatens “secondary sanctions” against foreign companies that continue to fuel, provide landing services, sell tickets to, or otherwise support Iranian airlines. Other coverage also describes Bessent’s earlier “economic D-Day” warning and a plan to choke off financial ties.
Outlets largely align on the date—September 23—and the core mechanism: U.S. sanctions are designed to deter third parties by raising the risk of being “knocked out” of the dollar system. Coverage differs mainly in emphasis: some focus on canceled flights and the immediate impact on operations, while others underline the broader sanctions framework and enforcement threat.
