As of early March 2026, Iran has effectively blocked the Strait of Hormuz through a combination of declaring the critical waterway closed, threatening to target ships, and causing a halt in vessel transit following major regional military escalations. The blockage is enforced by the Islamic Revolutionary Guard Corps (IRGC) using threats of attacks on tankers and has caused insurance, and therefore shipping, to stop.
Key Methods of Blockage (March 2026):
Direct Threats & Prohibitions: IRGC officials declared the Strait closed, threatening to set fire to any vessel attempting to pass.
Effective Shutdown: Shipping in the strait has come to a "slow crawl" or total halt, with vessels not broadcasting signal, indicating a stoppage rather than a total physical barrier.
Economic Exclusion: Insurance providers withdrew coverage, making it financially impossible for commercial vessels to operate in the area.
Potential Tactics Involved:
Naval Mines: Deployment of naval mines by fast attack boats and submarines.
Asymmetric Attacks: Use of fast boats, drones, and anti-ship missiles to attack vessels.
GPS Jamming: Disruption of navigation signals in and around the waterway.
The strait, which transports about 20% of global oil and gas, is now considered a high-risk zone, causing significant global economic impact.
