Why it is a chokepoint
Exports from several major producers must pass through a limited sea lane. When access is uncertain, markets price not only lost volume but also vessel delays.

Why the Strait of Hormuz moves oil and shipping markets
The Strait of Hormuz is the narrow sea exit from the Persian Gulf. Large oil, product and LNG flows use it, so even the risk of restricted passage can quickly affect freight, insurance and prices.
What becomes expensive first
War-risk insurance, tanker rates and prompt cargo prices react first. Retail fuel follows later as the shock passes through crude, refining and inventories.
Can ships bypass it?
Some volumes can move through pipelines to other ports, but spare capacity and geography are limited. The sea route cannot be fully replaced at short notice.
The link to Azerbaijan
Azerbaijani crude does not transit Hormuz, but Azeri Light trades in the global market. Higher global risk can support export prices while also raising shipping, fuel and import costs.
Questions
Short answers
Must the strait close before oil rises?
No. Prices respond to the probability of disruption and extra costs before traffic actually stops.
Why can oil and gas react differently?
Flows, buyers, inventories and alternative infrastructure differ, so the same event does not affect every energy market equally.
What should I verify in a dramatic headline?
Actual vessel movements, insurance rates, official restrictions, rerouted volumes and the likely duration.
