US Treasury Sanctions 27 Iranian Airlines in Major Economic Action

The US Treasury Department has launched a significant initiative against Iran's airline industry, sanctioning 27 airlines and nine associated entities under a campaign termed "Operation Economic Outcast." This action, announced on September 8, extends sanctions to all remaining active Iranian airlines, citing their involvement in transporting weapons and personnel for the Islamic Revolutionary Guard Corps (IRGC).

The sanctions impact carriers that had retained some international operations, including Qeshm Air and Varesh Airlines, which had limited flights to Gulf states. Additionally, three aviation authorizations have been suspended, affecting overflight permissions and operations involving US-origin aircraft into Iran.

Treasury Secretary Scott Bessent warned that entities engaging with Iran's airline sector risk losing access to the global financial system. The Office of Foreign Assets Control (OFAC) has also alerted financial institutions regarding procurement networks utilized by Iranian airlines to acquire aircraft, identifying at least three Boeing 777s procured for Mahan Air through third-country facilitators primarily located in the UAE, Turkey, and Malaysia.

Mahan Air, Iran's largest private carrier, has been under US sanctions since 2011 due to its connections with the IRGC. The recent sanctions mark a shift in strategy, directly targeting the airlines rather than their support infrastructure, which had been the focus of earlier sanctions imposed in 2026.

The mention of procurement networks operating through the UAE, Turkey, and Malaysia raises concerns for companies in those regions, as they may face secondary sanctions that could cut them off from the US financial system. The involvement of Boeing in procurement alerts highlights the potential for legitimate supply chains to be affected by these sanctions.
