Iran is moving to tighten control over the Strait of Hormuz by requiring ships to follow new transit rules or risk possible attacks, according to documents reviewed by CNN.
The report said Iran’s newly created Persian Gulf Strait Authority now requires vessels to submit detailed information before entering the critical waterway. Tehran says the measures are necessary for safe passage amid ongoing regional tensions.

Since the U.S.-Israeli conflict with Iran began earlier this year, shipping traffic through the strait has collapsed sharply. Analysts told CNN that Iran appears determined to formalize long-term control over one of the world’s most important oil routes.
The Strait of Hormuz handles roughly one-fifth of global oil and liquefied natural gas shipments. Rising tensions have already pushed energy prices higher and disrupted international trade.

According to maritime analysts, shipping firms face growing pressure because complying with Iran’s rules could expose them to potential U.S. sanctions under Trump administration policies.
