How this development reaches the affected companies
| Asset | Exposure and channel | Direction | Evidence |
|---|---|---|---|
| BZ=F | Lower effective Gulf exports increase the supply-risk premium in Brent crude. | Upintraday | Kpler data cited in reporting showed only 2.9 million barrels transited the waterway on October 11, the month's lowest level, while Brent reached $110 on Friday. |
| CL=F | Disrupted Middle East flows increase the global crude shortage premium for WTI. | Up1-5d | Reporting linked sharply reduced Hormuz traffic to tighter energy markets and higher oil prices. |
| BDRY | Threats to tanker passage raise freight rates and support dry-shipping exposure. | Up1-5d | Attacks and reduced vessel transits increased the cost and risk of passage through the waterway. |
