Iran has firmly rejected a United States proposal to establish a parallel shipping corridor within the Strait of Hormuz, stating that no provision in the current memorandum of understanding permits such an arrangement.

The rejection, reported by state-affiliated Press TV, underscores Tehran's insistence on maintaining exclusive control over the critical waterway, dismissing any attempt by Washington to create an alternative transit mechanism under its own auspices.

The development reinforces the geopolitical friction that has kept shipping risk premiums elevated in the region.

With the Strait of Hormuz handling a significant portion of global oil trade, any perceived threat to its stability or sovereignty directly impacts energy market sentiment.

The refusal to accommodate a US-led corridor suggests that diplomatic de-escalation remains distant, leaving traders to price in continued uncertainty regarding tanker routes and insurance costs.

This diplomatic rebuff comes amid a broader escalation in Gulf tensions.
