Two oil tankers erupted in flames in the Persian Gulf on Wednesday, March 11, 2026, following a suspected Iranian attack, resulting in at least one confirmed fatality and sending crude oil prices briefly above $100 a barrel. The incidents, occurring amid heightened tensions following U.S. And Israeli strikes on Iranian targets in late February, have effectively closed the Strait of Hormuz to commercial shipping, triggering concerns of a major global energy crisis.
The attacks targeted vessels in the critical shipping lane, prompting a swift response from regional naval forces. The U.S. Navy reported destroying more than a dozen mine-laying Iranian vessels on Tuesday, a move Iran vowed to retaliate against by blocking all oil exports to its adversaries. The Islamic Republic stated it would not permit “even a single liter” of oil to reach those it considers enemies, according to reports.
The Strait of Hormuz, a narrow waterway connecting the Persian Gulf to the Gulf of Oman, is a vital chokepoint for global energy supplies. Approximately one-fifth of the world’s oil and liquefied natural gas shipments typically transit the strait, making it a strategically crucial passage. Its closure has already begun to disrupt global oil markets, with gasoline prices rising sharply, according to reports from Texas.
The current situation is rooted in a complex geological history. Iran’s oil reserves are largely contained within a foreland basin created by the collision of the Arabian and Eurasian tectonic plates, a process that similarly formed the Zagros Mountains. This geological formation effectively traps oil within the region and funnels it towards the narrow exit point of the Strait of Hormuz.
The disruption to shipping comes after the U.S. And Israel launched attacks on Iran on February 28, escalating regional tensions. Prior to the recent attacks, ships were observed lining up in front of Ras Al-Khaimah in the United Arab Emirates, anticipating potential disruptions to transit through the Strait. Governments are currently developing plans to reopen the waterway to shipping once hostilities cease, but the logistical challenges are significant.
The infrastructure supporting global oil and gas supplies – pipelines, refineries and shipping terminals – is now directly at risk. An oil storage facility in Tehran was reportedly struck by a U.S.-Israeli attack on March 8, 2026, further exacerbating concerns about the security of energy infrastructure in the region.
The U.S. Navy led a naval convoy in 1987 during the Iran-Iraq war to protect shipping through the Gulf, a precedent that may be considered as the current crisis unfolds. As of Wednesday, March 11, 2026, the United Arab Emirates Navy was patrolling the Strait of Hormuz, attempting to secure the vital waterway.
