A serious escalation has occurred in the Strait of Hormuz, as Iranian military forces have reportedly laid mines in part of the strategically vital waterway. The strait — a critical maritime chokepoint for global oil and liquefied natural gas (LNG) shipments — has become the focal point of mounting tensions, with Iran effectively imposing a naval blockade that has sent shockwaves through global energy markets.
According to Iranian intelligence sources cited by Reuters, Tehran has deployed approximately 12 naval mines in the area. This move is expected to further disrupt freedom of navigation along one of the world’s most important sea lanes — through which about one-fifth of global oil and LNG exports normally pass.
Oil and LNG exports via the Strait of Hormuz, along Iran’s southern coast, have essentially halted since the outbreak of hostilities 12 days ago — contributing to sharp increases in global energy prices. On Wednesday, March 11, 2026, the Iranian military warned that the world should prepare for oil prices potentially reaching $200 per barrel.
An Iranian source confirmed that the locations of most of the mines are known, but declined to disclose how the United States plans to respond or neutralize them. Tehran’s ability to restrict maritime traffic serves as a significant lever of pressure against the U.S. and its allies.
