Question
Iran’s Revolutionary Guard Corps Navy declares the Strait of Hormuz closed to ships without Iranian approval and denounces US claims of reopening as lies
Direct answer

How this development reaches the affected companies
| Asset | Exposure and channel | Direction | Evidence |
|---|---|---|---|
| BRN00 | Iran’s insistence that Hormuz remains closed without its approval preserves significant tail‑risk to global oil supply through the chokepoint | Up1-5d | IRGC Navy stated the Strait of Hormuz remains closed to ships seeking passage without Iran’s approval and called US claims of reopening a lie, while analysis highlights shipping volumes still far below pre‑war levels. |
| VLCC-SPOT | ongoing IRGC‑enforced restrictions and projectile incidents keep war‑risk insurance and spot freight rates elevated for Gulf routes | Up1-4w | IRGC declared decisive control and closure conditions for ships without approval; supertanker earnings on the Saudi–China route are reported at record US$647,000 per day due to Gulf war risk and partial Hormuz blockages. |
| GLD | persistent uncertainty over Hormuz access and US‑Iran confrontation supports demand for gold as a geopolitical hedge | Up1-5d | Multiple reports frame Hormuz passage as the “core switch” for global oil and note war‑driven disruption, with markets still pricing unresolved geopolitical risk despite some easing in crude. |
