Iran’s Islamic Revolutionary Guard Corps Navy confirmed through Fars News that at least 33 ships, including oil tankers, transited the Strait of Hormuz with Iranian permission within a 24-hour period. The announcement came as Tehran and Washington discussed arrangements to ensure safe navigation after weeks of disrupted traffic.
Commercial shippers have faced uncertainty over insurance, routing and clearance procedures while conflict persisted in the Gulf. Iran’s statement suggested a controlled reopening under terms that would preserve Tehran’s leverage over the waterway.
Energy markets reacted cautiously to reports of increased tanker movement, with analysts noting that sustained flows depend on formal agreements rather than ad hoc approvals. Gulf exporters rely on the strait for the majority of their overseas crude shipments.
The IRGC Navy’s tally included oil tankers among vessels granted passage, indicating selective clearance rather than a fully open corridor. Shipping executives said predictable rules remain essential before insurers and charterers normalize routes through the strategic chokepoint.
Fars News, carrying IRGC Navy reporting, said permission was granted for at least 33 vessels within a single 24-hour window. Oil tankers were among the ships listed, indicating that energy cargoes remain central to the controlled transit regime Tehran has described during ceasefire discussions.
