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

| CL=F | Higher Middle East disruption risk supports US crude futures through a stronger global oil risk premium. | Upintraday | WTI rose 76 cents to $98.58 in the cited market reaction. |
| Z | Higher perceived attacks on Saudi export infrastructure increase expected marine-war and supply-chain risk for tanker exposure. | Down1-5d | A supertanker reportedly struck a sea mine south of Hormuz and Reuters reported at least 18 vessel attacks over two weeks. |
