Bessent Says US Sanctions Will Shut Down All Iranian Airlines Worldwide From Sept. 23

US Treasury Secretary Scott Bessent said new US sanctions taking effect September 23 will force airports, fuel suppliers, and ticketing companies worldwide to cut off Iranian airlines or face expulsion from the dollar system. Bessent said 'if they land, you cannot provide them with fuel, you cannot provide them with landing services, you cannot sell them tickets or you will be knocked out of the dollar system,' targeting remaining Iranian carriers not already sanctioned earlier this month.

Why this matters. The threat effectively grounds Iran's international civil aviation fleet within 48 hours by cutting off fuel, landing rights, and ticketing access at any foreign airport, deepening the isolation of Tehran's economy amid the ongoing war.
