How this development reaches the affected companies
| Asset | Exposure and channel | Direction | Evidence |
|---|---|---|---|
| CL=F | Lower effective Gulf transit capacity increases the disruption premium embedded in crude prices. | Up1-5d | The cited maritime report recorded traffic about 75% below pre-conflict levels and 10 attacks in the strait during the week. |
| BDTI | Fewer safe transits and more attacks increase vessel scarcity, war-risk premiums and voyage costs. | Up1-5d | The report recorded 11 vessel attacks and sharply reduced traffic. |
| USO | A sustained Hormuz disruption risk supports the crude exposure held by the oil fund. | Up1-5d | Reported shipping traffic was substantially below pre-conflict levels, with attacks continuing in the strait. |
