Treasury Sanctions 36 Targets, Wiping Out What Remains of Iran's Airline Industry

Since President Trump launched Operation Economic Outcast on August 24 to sever Iran's remaining financial lifelines, Washington has now moved to knock out the one sector it hadn't fully touched: civil aviation. On September 8, the Treasury Department's Office of Foreign Assets Control sanctioned 36 targets, including 27 Iranian airlines, in what officials call the most sweeping aviation crackdown on Tehran yet.

An anonymous Treasury official put it bluntly to reporters, according to the Times of India: "Essentially, we're taking the entire aviation sector of the Iranian economy out of the market." Radio Free Europe/Radio Liberty published the actual roster: Iran Aseman Airlines, Iran Airtour, Kish Airlines, Qeshm Air, Karun Airlines, Sepehran Airlines, Taban Airlines, Varesh Airlines, Zagros Airlines, Chabahar Airlines, Fly Persia, Saha Airlines, Air Shiraz, Ava Airlines, Fly Kish, Mehr Airways, Raimon Airways and Soroush Air. That's every carrier Iran has left running.

Treasury Secretary Scott Bessent didn't mince words either. "Let this be a warning to anyone doing business with Iran's remaining airlines, all of which we sanctioned today: You are at risk of being cut off from the global financial system," he said in a statement carried by the Associated Press and republished across PBS, ABC News, WTOP and News4Jax.

Nine countries, one workaround network

Eight of the newly sanctioned entities are based outside Iran, in Turkey, the UAE, Malaysia, Kazakhstan and the UK, according to the Epoch Times. Treasury says these firms helped Mahan Air, sanctioned since 2011 for ties to the Islamic Revolutionary Guard Corps, keep flying anyway.

RFE/RL reports Treasury's specific allegation: Mahan Air took delivery of at least three Boeing 777s during the summer of 2026, routed through the UAE and Oman using UAE-based ECT Aviation Support and Turkey-based Sky Phoenix as go-betweens. ECT's owner, Egyptian-UAE national Mahran Ibrahim Ali Mohamed Mahran, was personally sanctioned. Malaysia's iCargo, Kazakhstan's Tour Invest, and Turkish firms MES Cargo and S Sistem Logistics round out the foreign target list.

Boeing aircraft don't get to Tehran without a lot of paperwork and a lot of middlemen. Sanctioning the middlemen, not just the airline, is the correct move if the goal is actually cutting off supply rather than just issuing another press release.

The war hasn't stopped

This economic squeeze is running alongside an actual shooting war that started February 28 and passed its six-month mark in August, with no ceasefire. WTOP and News4Jax both report that hours after Tuesday's sanctions, the U.S. military struck multiple Iranian tankers in response to attempted missile attacks on a Navy warship. Al Jazeera adds that Iran launched attacks on U.S. forces in Jordan the same day.

Bessent has called this campaign an "economic D-Day" and the "toughest sanctions in history," per Al Jazeera. Iranian Foreign Minister Abbas Araghchi mocked that framing directly on social media: "After failing to achieve its aims through sanctions or war, Washington's 'novel' solution is…more sanctions. Seriously?" Sanctions have been piling on Iran since the 1979 revolution, per WTOP, and the regime is still flying jets and firing missiles.

The counterargument, and it's a solid one: an aviation ban that blocks weapons and personnel movement is a legitimate military-adjacent tool, not just economic theater. Cutting Mahan Air's supply chain for U.S.-origin aircraft parts is a concrete degrade of Iran's logistics capacity, whatever its immediate effect on the war's outcome.

What's still unresolved

Mohsen Rezaei, head of Iran's Supreme National Security Council, warned this week that Tehran will respond to the economic pressure by declaring a maritime exclusion zone over the Persian Gulf, according to the Epoch Times. Vessels entering without coordinating with Iran would risk being sanctioned by Tehran itself.

Whether Iran actually attempts to enforce that zone, and whether the U.S. Navy treats it as a provocation requiring a response, is the next flashpoint to watch. Iran had not issued a formal public response to the September 8 aviation sanctions as of this writing, according to RFE/RL. Whether the remaining airlines simply keep flying under the radar, as sanctioned Iranian carriers have managed to do for over a decade, remains the open question Treasury's own track record doesn't answer.
