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

| CL1! | A record attack pace increases the probability of delayed or diverted crude shipments and supports a transit-risk premium. | Up1-4w | Maritime data showed October was the most intense month for attacks around Hormuz in the reported period. |
| ZIM | Repeated attacks and higher security costs can reduce Gulf-linked shipping volumes and raise operating expenses for exposed carriers. | Down1-4w | The reported incidents affected commercial shipping across Hormuz and nearby waterways. |
