How this development reaches the affected companies
| Asset | Exposure and channel | Direction | Evidence |
|---|---|---|---|
| BRENT CRUDE | Lower effective flow through the primary Gulf export chokepoint tightens expected prompt supply. | Upintraday | Reuters reported that Hormuz transits reached a two-month low and that crude flows had fallen 27% from the previous week's peak. |
| DUBAI CRUDE | Lower Gulf export throughput directly raises the regional physical crude premium. | Up1-5d | Kpler data cited in reporting showed flows through Hormuz at roughly 74% of pre-war levels. |
| BDTI TANKER FREIGHT | Fewer transits amid more attacks increase risk-adjusted freight and insurance pricing. | Up1-5d | Maritime-security sources cited by Reuters said tanker attacks reached their highest weekly level since the war began. |
| LNG FREIGHT | Security constraints around Hormuz increase vessel scarcity and voyage-risk pricing for LNG movements. | Up1-5d | The reported attacks included vessels carrying oil, liquefied natural gas and liquefied petroleum gas. |
