The Treasury Department on Tuesday sanctioned 27 Iranian airlines and several other entities, a sweeping move that extends the U.S. campaign to choke off Iran’s economy as regional hostilities drag past the six-month mark.
The action falls under what the administration calls “Operation Economic Outcast” and targets every Iranian carrier not already under sanctions, effectively cutting off the country’s remaining commercial aviation network from international finance and trade.
Treasury Secretary Scott Bessent framed the step as a warning to companies and individuals who might still be tempted to do business with Iran’s airlines, all of which now sit on the U.S. blacklist.
“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,” Bessent said in a statement.
The latest sanctions arrive as Tehran and its proxy forces continue to launch attacks in and around the Strait of Hormuz, a chokepoint for roughly a fifth of global oil supply. Those strikes have drawn other countries deeper into a conflict that began more than six months ago and have kept upward pressure on crude prices.
Oil markets react
Oil rose following the announcement, reflecting heightened concern that the expanded sanctions — and the broader escalation around the strait — could further tighten supply in a market already braced for disruption.
The U.S. campaign has steadily widened its economic net around Iran since the start of the war, targeting everything from energy exports to financial institutions. Tuesday’s action extends that effort to aviation, a sector that had remained partially outside the sanctions regime until now.
The Treasury’s move blacklists the named carriers and affiliates, prohibiting U.S. persons from engaging in transactions with them and freezing any U.S.-held assets. Foreign firms that continue to deal with the sanctioned airlines also risk losing access to the U.S. financial system, according to the department.
Analysts said the aviation sanctions are unlikely to cripple Iran’s military capabilities but could further isolate the country commercially and complicate humanitarian and passenger travel routes that had still been operating.
The announcement was made late Tuesday and is breaking news. Additional details on the full list of sanctioned entities and the potential scope of the economic impact are expected to emerge in the coming days.
