US Treasury Sanctions 27 Iranian Airlines in Total Aviation Blockade
The US Treasury Department has sanctioned all 27 remaining Iranian commercial airlines under Operation Economic Outcast, moving to cut the country’s aviation sector off from international banking, maintenance networks, and global supply chains.
The sweeping designations hit 36 total targets, including cross-border intermediaries and support networks accused of procuring US-origin aircraft, replacement parts, and sensitive technology for Iranian carriers.
Global Aviation Suppliers and Intermediaries Face Financial Severance
The sanctions create immediate secondary-sanctions risk for foreign companies, maintenance providers, and financial institutions operating in the international aviation supply chain. Treasury Secretary Scott Bessent explicitly warned that any firm continuing to handle transactions, supply aircraft parts, or provide technical servicing to the designated carriers risks losing access to the US financial system entirely.
The Treasury designated Mahan Air alongside broader network targets, asserting that third-party companies helped the carrier acquire aircraft and services despite long-standing prohibitions. U.S. officials maintain these commercial aviation channels were regularly used to move military personnel, weapons, and illicit cargo.
Iranian Foreign Minister Abbas Araghchi dismissed the economic campaign as ineffective, stating that decades of American sanctions have failed to alter Tehran’s national policies.
The enforcement action hits an aviation sector already struggling with maintenance backlogs, restricting how Iranian carriers handle routine aircraft maintenance, source structural components, or settle foreign aviation accounts. Foreign executives and aviation services providers dealing with Middle Eastern transport networks will need to verify counterparty exposure immediately to avoid inadvertently facilitating transactions for the 27 blocked carriers or their procurement proxies.
