Treasury officials claim the move effectively neutralizes the vast majority of Tehran's remaining clandestine shipping network, though analysis by TankerTrackers shows 173 Iran-linked vessels remain unsanctioned, including 54 within a US naval blockade. Washington estimates 20 million barrels of crude oil are currently aboard ships outside that perimeter, while CENTCOM has destroyed 13 commercial vessels over 12 weeks. Global tanker utilization is currently at 100%, which may further strain international shipping capacity as more ships are restricted.
