Can Iran enforce a restricted zone in the Strait of Hormuz?

What the report says

Al Jazeera reports that Iran plans to create a new restricted zone around the Strait of Hormuz, a critical shipping passage for global energy trade, after a fresh round of tension with the United States over tanker traffic and naval patrols. The announcement follows the expiration last month of a 60-day memorandum of understanding that had temporarily eased maritime hostility between the two sides.

According to Iranian officials cited by Al Jazeera, the proposed zone would begin near the line of a US naval blockade and extend toward the strait and into parts of the Persian Gulf. Tehran says vessels entering the area could be placed on Iran’s sanctions list, but it has not released precise borders or explained what that designation would practically mean. The report also says Iran and Oman have been discussing a separate managed shipping corridor, while the International Maritime Organization has been involved in efforts to support safer passage.

The article says there has been no immediate public response from Washington specifically to the new zone plan, though the US rejected an Iranian claim that a US vessel entered a restricted area and was attacked. Al Jazeera adds that traffic through the strait is still moving, but at lower levels than before the conflict, with commercial flows and ship counts both reduced. The wider significance is that Iran appears able to disrupt shipping, but it is uncertain whether it can fully enforce a broader exclusion zone, especially against vessels backed by US forces.
