In October 2026, the Strait of Hormuz witnessed a surge in attacks on commercial vessels, with at least 12 confirmed incidents reported by the UK Maritime Trade Operations (UKMTO) as of October 16. The attacks are attributed to ongoing tensions between the US and Iran, with Iran reportedly targeting at least 24 vessels in a two-week timeframe. The US military claims to have maintained control over the Strait, facilitating the transit of 400 ships and 100 million barrels of oil despite the attacks. New tactics employed by Iranian forces include the use of small boats and rocket-propelled grenades (RPGs) against tankers. The situation has led to increased oil prices, with Brent crude reaching $110 a barrel. US Central Command (CENTCOM) asserts that the Strait is under US control, while Iranian officials warn of potential retaliation against US and allied targets. The conflict has escalated amid a backdrop of military posturing from both nations, including the presence of US aircraft carriers in the region.
