What Happened
The US Treasury Department removed sanctions designations from an Iranian Revolutionary Guards Corps (IRGC) linked company as negotiations advance toward a broader US-Iran accord. Treasury officials publicly denied this signals a policy shift toward Iran or the IRGC, but the action contradicts official US position that IRGC entities remain under sanctions. The removal suggests the Trump administration is willing to trade IRGC-affiliated company sanctions relief as part of a comprehensive deal package. This is the first concrete sanctions relief action by the administration toward Iran-connected entities since conflict escalation in July 2026. The removal occurred in parallel with public statements that Hormuz reopening talks are progressing.
