How this development reaches the affected companies
| Asset | Exposure and channel | Direction | Evidence |
|---|---|---|---|

| FRO | Higher attack risk can lift tanker freight and war-risk earnings for vessels able to operate through the route. | Up1-4w | The attacks specifically affected tankers sailing through the Strait of Hormuz. |
| GC=F | A more dangerous strategic chokepoint increases demand for geopolitical hedges. | Up1-5d | Reuters described a sharp increase in tanker attacks and renewed concern about the regional war. |
