The new US aviation sanctions are serious. Bessent had threatened that, beginning September 23, foreign companies that provide Iranian airlines with fuel, landing services, or ticket sales risk being “knocked out of the dollar system.”
It is the latest example of Washington weaponizing its financial dominance to maximize civilian suffering inside Iran, on top of years of sweeping sanctions and now multiple wars and a naval blockade.
For Tehran, this is also the latest test of its new more assertive security strategy. If a new form of US pressure is allowed to take hold without imposing costs in return, it risks becoming the new baseline.
Iran is therefore threatening reciprocal escalation: if regional states help Washington isolate Iranian aviation, Tehran says their airports could be disrupted as well.
The question is whether Iran follows through, and what Washington does if it does. Will the US actually punish countries that continue servicing Iranian aircraft? Or will Iranian counter-escalation raise the costs enough that Washington ultimately backs away from enforcing the threat?
Notably, Washington appears to have backed away from its recently announced “tanker-for-tanker” policy even as daily Iranian attacks on Persian Gulf shipping have continued, after the policy itself produced a sharp cycle of counter-escalation from Iran.
