Iran’s Revolutionary Guard Corps Navy claims attacks on three oil tankers and three US‑linked vessels on unauthorised Strait of Hormuz routes in response to US strikes

How this development reaches the affected companies
| Asset | Exposure and channel | Direction | Evidence |
|---|---|---|---|
| DHT | Claims of IRGC attacks on oil tankers and warnings about unauthorised routes raise operational risk, potential downtime, and insurance costs for crude tanker operators with exposure to Gulf routes. | Down1-5d | IRGC statements report targeting three oil tankers in Hormuz and cautioning vessels against using certain corridors, while broader coverage notes at least 23 vessels have been struck in the strait over recent months. |
| BALTIC_DRY | Elevated security risk and possible route diversions through Hormuz can lift regional freight rates for some segments while reducing throughput and fleet utilisation elsewhere. | Mixed1-4w | Reporting underscores a months‑long pattern of attacks on vessels in Hormuz and deadlock over transit volumes, implying uneven impacts on shipping trades depending on exposure. |
| BRENT | Reported Iranian attacks on additional tankers and threats against unauthorised routes magnify fears of supply disruption through a chokepoint that carries a large share of global seaborne oil. | Up1-5d | Coverage describes continuing disruption in the Strait of Hormuz and links conflict and attacks on Gulf shipping to elevated oil prices near or above $90–96 per barrel. |
