The Aviation Sanctions Straitjacket: What’s Behind the US Move Against Iranian Airlines?

The latest salvo in the ongoing standoff between Washington and Tehran has been fired, with US Treasury Secretary Scott Bessent threatening to effectively shut down Iranian airlines from Wednesday. This move is not a new chapter in the long-running saga of US sanctions against Iran but rather another page turned in an already well-worn book.

The aviation industry has been caught in the crosshairs for years, with US sanctions limiting Iranian carriers’ ability to acquire new aircraft and access spare parts and maintenance services. The Trump administration’s “maximum pressure” campaign against Iran aims to restrict its access to international financial and commercial networks, making this limitation a predictable consequence.

Tensions between the US and Iran are at an all-time high following the assassination of Qasem Soleimani in January. Given these heightened tensions, one might expect a ramping up of sanctions rather than new threats. However, Bessent’s statements suggest that the US is seeking to tighten the noose further still.

The practical implications of this move are stark: Iranian airlines will be forced to operate at a fraction of their former capacity, with fuel suppliers, airport operators, and ticket vendors caught in the crossfire. Bessent has warned that providing services to Iranian airlines risks being “knocked out of the dollar system.” This is not an idle threat; the US has a long history of using its financial muscle to wield influence over international businesses.

European airlines have been hesitant to take on Iranian routes, citing concerns about passenger and crew safety. The EU’s efforts to salvage the nuclear deal with Iran have not gone unnoticed in Washington, and it seems likely that these actions will be seen as a challenge to US authority. Other countries caught in the middle may find themselves similarly affected.

The move against Iranian aviation raises questions about the long-term efficacy of sanctions as a tool for foreign policy. The history of US-Iran relations is marked by cycles of escalation and de-escalation, with each new round of sanctions seeming to harden Iranian resolve rather than weaken it. Is this latest move simply another iteration in an endless loop?

The coming weeks will be crucial in determining the impact of these measures. Will foreign companies comply with the US demands or find creative ways to circumvent the restrictions? How will Iran respond to what it sees as yet another attempt to strangle its economy? One thing is certain: this latest move will only serve to further entrench the divisions between Washington and Tehran.

As the world watches, one thing becomes clear: the aviation sanctions regime has become a self-perpetuating cycle of tit-for-tat. The question now is whether this will be a temporary blip on the radar or another step down the road towards all-out confrontation.
