Iran’s top security official insists Strait of Hormuz remains closed to US‑linked shipping despite selective passage for Iraqi oil tankers
Question
Iran’s top security official insists Strait of Hormuz remains closed to US‑linked shipping despite selective passage for Iraqi oil tankers
Direct answer
Iran’s insistence on keeping Hormuz closed to most traffic, combined with only narrow exemptions, sustains extreme supply‑disruption risk and reinforces higher risk premia for crude, LNG and regional shipping assets.

How this development reaches the affected companies
| Asset | Exposure and channel | Direction | Evidence |
|---|---|---|---|
| BRN00 | A contested closure of Hormuz and minimal commodity transits support elevated Brent prices via expectations of sustained export constraints from key Gulf producers. | Up1-3m | Maritime briefs reported near‑zero commodity transits and hundreds of vessels holding, while Iranian officials declared the strait closed and only a handful of Iraqi oil tankers were permitted passage. |
| LNGJKM | Disruption of Gulf LNG routes through Hormuz tightens Asian spot LNG balances and lifts benchmark prices. | Up1-4w | Regional coverage linked sharply reduced Hormuz traffic and fading hopes of reopening the strait to a five‑month high in Asian spot LNG prices. |
| INSUR | War‑risk and hull insurance premia for vessels transiting or rerouting around Hormuz rise with contested closure and attack threats, supporting insurer pricing power and margins. | Up1-3m | Maritime risk commentary highlighted extreme crisis indices, vessel holds and threats against unauthorised tankers, conditions historically associated with rising war‑risk premia. |
