U.S. Treasury Announces Global Shutdown of Iranian Airlines Effective September 23, 2026
By Drooid · · How we work
Core Event
U.S. Treasury Secretary Scott Bessent warned that, beginning September 23, all Iranian commercial airlines will be forced to cease operations worldwide. The announcement ties the shutdown to secondary sanctions that would cut off any foreign airport, fuel supplier, ticketing firm, or other service provider from the U.S. dollar clearing system if they continue to support Iranian carriers.
Background & Context
The measure follows a series of U.S. sanctions targeting Iran’s aviation sector throughout 2026. Earlier in the month, the Treasury imposed sanctions on “all remaining Iranian airlines” that had not yet been targeted, adding to an existing regime that has long restricted Iran’s ability to acquire aircraft, spare parts, and maintenance services. The sanctions are part of “Operation Economic Fury,” aimed at isolating Tehran’s financial networks amid the Iran-U.S.–Israel conflict that began in February 2026.
Timeline
- September 20 (occurred) – Bessent met Chinese Vice-Premier He Lifeng in New York to discuss enforcement of sanctions.
- September 23 (scheduled) – All Iranian airlines are slated to be shut down worldwide under the new secondary sanctions.
- September 24 (scheduled) – A U.S.–China summit with President Donald Trump and President Xi Jinping is planned, following the Treasury’s announcement.
- September 17 (occurred) – Mahan Air cancelled flights to Oman (effective September 17) and Turkey (effective September 21) after pressure from Omani and Turkish authorities.
Data & Statistics
Official Statements & Responses
Bessent said the United States has identified foreign actors that facilitate Iran’s aviation and is moving to stop them.
Chinese officials, including People’s Bank of China Governor Pan Gongsheng, were described as “very engaged” in behind-the-scenes discussions about enforcement.
Iraqi sources reported that Baghdad would suspend flights by Iranian airlines. Georgia also barred Iranian carriers from its territory.
Iranian authorities have not issued an immediate public response. Mahan Air cited Omani and Turkish aviation decisions as the reason for its cancellations, while Iran Air continued domestic flights to Iraq’s Najaf Airport, according to the semi-official Student News Agency (SNN).
On-the-Ground Reports
- Iraq: Officials indicated a suspension of Iranian airline flights into the country.
- Georgia: The government barred Iranian carriers from landing.
- Mahan Air: Cancelled scheduled services to Oman and Turkey after pressure from those nations’ regulators.
Conflicting Reports & Gaps
Sources differ on the exact composition of the sanction package: some report 27 Iranian airlines sanctioned, while others cite 36 entities that include those airlines. No Iranian government spokesperson has publicly commented on the impending shutdown.
Why It Matters / Impact
If enforced, the sanctions would isolate Iran’s civil aviation network, limiting international travel for Iranian civilians and disrupting cargo routes used by the Revolutionary Guard. Foreign firms that continue to service Iranian carriers risk losing access to U.S. dollar transactions, potentially reshaping global aviation service markets. The move also signals heightened U.S. pressure ahead of the September 24 summit with China.
What’s Next
The Treasury’s sanctions will take effect on September 23. U.S. officials indicated that compliance discussions with Chinese financial authorities will continue, and the upcoming September 24 U.S.–China summit may address further coordination on Iran-related measures.
