Executive summary

The Strait of Hormuz remains effectively closed as military hostilities escalate between the U.S. and Iran. Recent ship tracking data indicates a drastic reduction in maritime traffic, with oil and gas shipments severely impacted. Iran's stance suggests that any potential reopening of the strait hinges on U.S. concessions regarding sanctions.

The Strait of Hormuz has reverted to a de facto closure amid renewed military strikes between the U.S. and Iran. The U.S. has reinstated its naval blockade at one end of the strait, effectively resetting the ceasefire agreement established last month. Current ship tracking data reveals that verified crossings have plummeted to fewer than 10 vessels per day since July 18, marking a significant decline in traffic. Even when accounting for shadow fleet crossings, the numbers remain low, with only 13-19 vessels reported over the weekend.

Oil and gas shipments have largely stalled, with any passing tankers primarily linked to Iran or China. Since July 18, only one Very Large Crude Carrier (VLCC) has successfully crossed the strait, while liquefied natural gas (LNG) tankers have not transited since July 16, presenting a notable setback for Qatar.

Iran has indicated that the responsibility for reopening the strait lies with the U.S., which must offer concessions to facilitate a new agreement. This dynamic mirrors previous negotiations, with Iran previously allowing limited vessel passage before reinstating restrictions. Current reports suggest that former President Trump is contemplating either a renewed ceasefire or escalating military action against Iran, although the latter appears unlikely given the political ramifications ahead of the midterm elections.

Any potential new ceasefire is expected to mirror the previous agreement, with Iran likely to leverage the situation for further concessions regarding oil sanctions and frozen assets.
