Strait of Hormuz Closure Disrupts Oil Shipments, Escalates Regional Tensions
Iran has closed the Strait of Hormuz to traffic, a vital waterway for oil and gas shipments, following U.S. And Israeli attacks on Saturday. The move has prompted oil majors and traders to suspend shipments, raising concerns about global energy supplies and escalating regional tensions.
Iran Cites Safety Concerns
The Iranian Revolutionary Guards (IRGC) issued a safety warning to ships in the area, citing “military aggression by the United States and Israel” and Tehran’s responses as the reason for the closure. Tasnim news agency reported that the IRGC stated “it is currently unsafe to pass through the strait.”
Regional Impacts and Interceptions
Iran’s retaliatory attacks have alarmed neighboring countries, including the United Arab Emirates, Kuwait, Qatar, and Bahrain. Missiles have reportedly struck cities such as Doha, and Dubai. Although the UAE Ministry of Defense claims to have successfully intercepted several Iranian missiles, some reportedly bypassed defenses, causing building fires and panic. One civilian was reportedly killed by falling debris. Journalists in Doha and Dubai witnessed missile flights and impacts.
Israeli Response and Palestinian Vulnerability
Israel was the primary target of Iranian counterattacks, resulting in a few dozen injuries. An individual in their 50s was injured by an explosion in Ka’abiyye-Tabbashone, while a 16-year-old and a 17-year-old were hit by shrapnel in an Arab-Israeli city near Tel Aviv. The Palestinian community in Israel has expressed concerns about a lack of shelters and strong rooms, making them more vulnerable during rocket attacks.
The Israeli military stated it had completed a “broad attack” against Iranian defense systems, including a site in western Iran. Prior to this, Israel conducted a bombing campaign on Iran in June 2025, which was subsequently met with Iranian missile attacks.
Oil Market Reaction and Potential Price Increases
The closure of the Strait of Hormuz is expected to significantly impact global oil prices. Approximately 20% of global oil supply, originating from Saudi Arabia, the UAE, Iraq, Kuwait, and Iran, passes through the strait, along with substantial volumes of liquefied natural gas (LNG) from Qatar . Several tanker owners, oil majors, and trading houses have already suspended shipments .
As of March 1, 2026, West Texas Intermediate (WTI) crude oil was pricing as high as $75.33, a 12% increase from Friday’s close . Equirus, a Mumbai-based broking firm, estimates that a disruption of 3.3 million barrels per day (approximately 3% of global supply) could raise crude oil prices to $76–$81 per barrel. Dolat Capital projects a price of $100 per barrel if the Strait of Hormuz remains shut down .
Strait of Hormuz: A Critical Chokepoint
The Strait of Hormuz, located between Iran and Oman, connects the Persian Gulf to the Gulf of Oman and the Arabian Sea. At its narrowest point, it is approximately 33 kilometers (21 miles) wide, with designated shipping lanes only around 3 kilometers (2 miles) wide . Despite its limited width, it is considered an international transit route and a crucial energy chokepoint. Qatar, the world’s largest LNG exporter, relies almost entirely on the Strait for its shipments.
Naval Advisories and Shipping Disruptions
The U.S. Navy has warned against navigation in the Gulf, Gulf of Oman, North Arabian Sea, and the Strait of Hormuz, stating it cannot guarantee the safety of shipping. Greece’s shipping ministry has advised vessels to avoid the Persian Gulf, the Gulf of Oman, and the Strait of Hormuz . The UK Navy has advised vessels to transit with caution, noting that Iran’s orders are not legally binding. Satellite images show vessels piling up near ports like Fujairah in the UAE, with limited movement through the strait . Fourteen LNG tankers have slowed down, changed course, or stopped in or around the Strait, potentially impacting Qatari LNG exports .
