The United States announced a broad set of measures against Iran’s civil aviation sector on Tuesday, targeting dozens of carriers and related service firms and effectively withdrawing a range of licences that previously allowed aviation payments and support, a US Treasury official said.
Sanctions, licences and the aim to choke finances
The actions include sanctions on 27 Iranian airlines and nine service providers and sales agents accused of acting for or providing services to Mahan Air, a private Iranian carrier that has been under US sanctions since 2011. Mahan Air is accused of supporting Iran’s Islamic Revolutionary Guard Corps (IRGC), the official said.
Officials described moves to cut off operators in other countries that have been facilitating services to Iran. The targeted service providers and sales agents are located in Turkey, Malaysia, Kazakhstan and the United Arab Emirates, the Treasury official said.
“These jurisdictions have been on notice for some time, and now we’re moving quite directly to essentially cut off those operators from the Western financial system,” the Treasury official said.
In addition to the new sanctions, the US Treasury said it was "effectively today terminating all licences that related to aviation," including permissions that had covered payments for overflights of Iranian airspace and authorisations previously permitting non‑US carriers to fly US export‑controlled aeroplanes into Iran. Officials also said a general licence that allowed for safety and other emergency aviation support had been pulled back, though they left open the prospect of case‑by‑case exceptions.
What the measures do, and what they don’t
Officials framed the package as an attempt to sever Tehran’s access to funds that could be used to sustain its military and political operations. The Treasury official said the measures were intended to take “the entire aviation sector of the Iranian economy out of the market.”
- Sanctions on carriers: 27 Iran‑registered airlines were listed.
- Service providers targeted: Nine firms and sales agents in four countries identified as supporting Mahan Air.
- Licences revoked: Broad aviation licences, including those covering payments for overflights and emergency safety support, were terminated.
Former US deputy special envoy for Iran Richard Nephew, cited by the reporting, said the airline restrictions could be meaningful chiefly by limiting opportunities for covert procurement and complicating cargo and business transfers. He noted that tourism to Iran had already dropped, meaning the measures would most directly affect commercial and logistic flows.
“Tourism has dried up, not surprisingly, so this mainly hinders business and cargo transfers,” Richard Nephew said.
Context and consequences
The latest steps come amid a broader US effort to squeeze Iran’s financial channels. Administration officials have tied the sanctions to a campaign aimed at limiting Tehran’s ability to fund its military activities, including those connected to the conflict described by US officials as ongoing in the region. Treasury Secretary Scott Bessent, according to the reporting, has even mentioned regime change as a possible end state connected to the policy of pressure.
Practical consequences will include difficulties for Iranian carriers to obtain parts, services and insurance that rely on access to the Western financial system, and constraints on airlines and airports that had provided ancillary services. Officials warned that further measures — for example, against airports providing services to sanctioned carriers — could be considered, which would further reduce transit options.
| Measure | Scope |
|---|---|
| Airlines sanctioned | 27 |
| Service providers and agents | 9 (Turkey, Malaysia, Kazakhstan, UAE) |
| Licences terminated | All aviation‑related licences cited by Treasury |
For governments, carriers and insurers operating in the affected jurisdictions, the announcement increases legal and financial risk when dealing with particular Iranian operators. It also raises the prospect of greater disruption to humanitarian and civilian aviation activity unless narrow exemptions are approved on a case‑by‑case basis.
Whether the measures will substantially alter Iranian strategic behaviour is a separate question. Analysts cited in the reporting suggested the impact may be tactical — complicating clandestine procurement and commerce — rather than a swift means to change political leadership in Tehran.
The move demonstrates how sanctions policy can reach into sectors considered part of everyday commerce to exert pressure on a state, and highlights the secondary effects on firms and countries that have served as intermediaries for air services and aviation payments.
