War-risk insurance at forty times normal levels and single-digit daily transits keep commercial traffic through the Strait of Hormuz effectively shut down
Question
War-risk insurance at forty times normal levels and single-digit daily transits keep commercial traffic through the Strait of Hormuz effectively shut down
Direct answer
An effectively shut‑down Hormuz with extremely expensive war‑risk cover entrenches higher transport costs and supply‑chain frictions for oil and LNG, supports a persistent price premium on Gulf crudes, and raises freight and insurance costs globally.

How this development reaches the affected companies
| Asset | Exposure and channel | Direction | Evidence |
|---|---|---|---|
| BRN00 | Near‑cessation of commercial traffic through Hormuz severely constrains Gulf export capacity, embedding a structural risk premium in Brent that is unlikely to disappear quickly. | Up1-3m | Analyses state that traffic through Hormuz has dropped to about five ships a day, a 95% reduction from earlier norms, and that war‑risk insurance has reached around 40× normal levels, with Brent still about 20–22% higher than before the war |
| LNG_ASIA | Disruption at Hormuz constrains LNG shipments from Qatar and other regional exporters, supporting Asian LNG prices via reduced flexible supply. | Up1-3m | Commentary emphasises that roughly one‑fifth of the world’s natural gas flowed through Hormuz before the war and that commercial traffic is now largely closed, implying constrained LNG export flows. |
| HUMR | War‑risk premiums 40× normal dramatically increase revenue per insured voyage for marine insurers covering Gulf traffic. | Up1-3m | Shipping risk coverage on August 30 explicitly notes war‑risk insurance around Hormuz at roughly forty times typical pricing and large operators ceasing use of the strait, indicating a highly priced residual market. |
