Iran’s Islamic Revolutionary Guard Corps (IRGC) Navy has reportedly warned vessels over VHF radio that they are not permitted to transit the Strait of Hormuz, according to a Reuters report. An official linked to the European Union’s naval mission described the critical maritime corridor as “closed,” though Iranian authorities have not officially confirmed issuing a formal shutdown order.
The development comes amid escalating hostilities involving Iran, the United States, and Israel, raising concerns over global energy security and trade stability.
Why the Strait of Hormuz Is Critical
The Strait of Hormuz is the primary maritime route for oil exports from the Gulf region. It connects major energy producers — including Saudi Arabia, Iran, Iraq, and the United Arab Emirates — to the Gulf of Oman and the Arabian Sea.
Any disruption to this narrow waterway can immediately impact global markets.
The strait is approximately 50 kilometers wide at its narrowest point and contains several shallow areas, making it strategically vulnerable during times of conflict.
According to the US Energy Information Administration (EIA), nearly one-fifth of the world’s oil supply passed through the Strait of Hormuz in 2024. A similar share of global liquefied natural gas (LNG) shipments — largely from Qatar — also relied on this route. More than 80 percent of those energy exports are destined for Asian markets.
Strategic Geography and Military Presence
The strait lies between Iran and Oman’s Musandam Peninsula and serves as a critical gateway from the Gulf to the Indian Ocean.
Iran controls several key islands near major shipping lanes, including Hormuz, Qeshm, and Larak. It also holds Greater Tunb, Lesser Tunb, and Abu Musa — territories disputed by the United Arab Emirates. These geographic positions provide Tehran with significant strategic leverage over maritime traffic in the region.
The IRGC Navy oversees operations in the Gulf and around the strait. Over the years, it has confronted foreign vessels during periods of heightened tension.
Energy and Trade Implications
While countries such as Saudi Arabia and the UAE operate alternative pipeline routes, these can only handle a limited portion of total exports. A prolonged disruption of the strait would therefore have immediate consequences for oil prices, LNG supply chains, shipping costs, and broader global trade.
Iran has previously threatened to block the Strait of Hormuz during times of conflict, particularly when facing sanctions or military pressure. Revolutionary Guard commanders have reiterated this warning on multiple occasions, including earlier this year.
With tensions rising, global markets and governments are closely monitoring developments in one of the world’s most strategically vital waterways.
