Iran has dramatically intensified its claims over the strategic Strait of Hormuz, announcing expanded military oversight across a vast section of one of the world’s most critical oil shipping routes — a move already triggering sharp reactions from Gulf nations and the United States.
According to newly released maps published by Iran’s recently established “Persian Gulf Strait Authority,” Tehran now claims military supervision over more than 22,000 square kilometers of waters surrounding the Strait of Hormuz. The disputed area reportedly stretches beyond Iran’s internationally recognized territorial waters and overlaps with maritime zones linked to Oman and the United Arab Emirates.
Iranian authorities declared that all vessels transiting through the Strait must now coordinate with and receive authorization from the new authority, signaling a major escalation in Tehran’s effort to assert control over the narrow but strategically vital waterway.
The Strait of Hormuz is considered one of the world’s most important energy chokepoints. Roughly one-fifth of global oil and gas supplies pass through the corridor connecting the Persian Gulf to international markets. Any disruption or military confrontation in the region could send global energy prices sharply higher and impact international trade routes.
The United States and several Gulf allies immediately rejected Iran’s expanded claims, calling them inconsistent with international maritime law. U.S. officials have reportedly instructed commercial shipping operators not to comply with any Iranian authorization demands, emphasizing that the strait remains an international waterway protected under global navigation rights.
The United Arab Emirates also dismissed Tehran’s announcement, with officials describing Iran’s claims as “nothing but fragments of dreams.” Regional analysts warn the dispute could significantly increase military tensions between Iran, Gulf states, and Western naval forces already operating in the area.
Iran has long argued that its geographic position gives it special security responsibilities in the Persian Gulf, particularly amid ongoing conflicts involving Israel, the United States, and regional proxy groups. However, critics accuse Tehran of attempting to militarize international trade routes and pressure global powers through strategic energy chokepoints.
Security experts say the latest move could increase the risk of confrontations involving oil tankers, commercial vessels, and military patrols operating near the strait. Global shipping companies are also closely monitoring developments as insurance costs and regional security concerns continue rising.
The dispute comes at a time of heightened instability across the Middle East, with ongoing tensions involving Iran’s nuclear program, regional military alliances, and fears of broader conflict involving Israel and the United States.
