The closure of the Strait of Hormuz threatens to disrupt approximately one-fifth of global oil and LNG trade, likely causing sharp rises in oil prices and increased shipping costs. Renewed US-Iran hostilities cast doubt on the durability of the ceasefire and could lead to sustained energy market volatility.
Iran's Islamic Revolutionary Guard Corps (IRGC) announced on Sunday the indefinite closure of the Strait of Hormuz after firing warning shots at a commercial vessel it accused of using an unauthorized route. The move escalates tensions with the United States, which had reportedly given Iran a deadline to stop firing on commercial ships. The US military launched a new round of strikes against Iran in response to an attack on a container ship. The Strait of Hormuz is a critical chokepoint for global oil and LNG trade, and its closure threatens to disrupt energy markets and revive concerns over freedom of navigation. Iran insists on its right to regulate passage, while the US demands unrestricted navigation. The dispute complicates ongoing diplomatic efforts, including a fragile ceasefire and a 14-point memorandum that calls for talks between Iran and Oman.
