US naval blockade of Iran threatens global oil supply. President Trump announced the US Navy will blockade Iranian ports starting Monday, preventing roughly two million barrels of Iranian oil daily from reaching world markets. This escalation follows failed peace talks in Islamabad between US and Iran negotiators. Iran's Revolutionary Guards warned that military vessels approaching the Strait of Hormuz would be treated as ceasefire breaches. The blockade applies only to Iranian-bound ships while allowing other vessels through the critical waterway. Iran currently exports approximately 1.84 million barrels per day, with over 180 million barrels floating on ships. Global oil markets face significant tightening as this geopolitical tension restricts a major crude source from international commerce.
