Strategic Implications

The US move may indicate a significant escalation in economic pressure on Iran, which could have far-reaching implications for the global aviation industry.

What Happened

Secondary Sanctions Target Foreign Airports And Suppliers

The US Treasury Secretary has announced that all Iranian airlines will be shut down worldwide from September 23, as part of a broader campaign to sever the remaining economic lifelines of the Iranian government. The move is aimed at foreign airports, fuel suppliers, and other companies that service Iranian airlines, threatening them with secondary sanctions if they continue to provide support. The announcement comes after the US designated 27 Iranian airlines under Executive Order 13902, including Iran Aseman, Qeshm Air, and Mahan Air, which has been accused of supporting the Islamic Revolutionary Guard Corps. The development was first reported by various news outlets, including CNBC and Reuters.
