The US blockade of Iranian ports aims to cut off Tehran's oil exports, which accounted for 40% of the country's export revenue in 2023. American warships and fighter jets are patrolling the Strait of Hormuz to enforce the blockade, targeting Iran's primary source of government income. The strategy seeks to pressure Iran into concessions during ongoing regional tensions.

Despite sanctions, Iran conducted about $110 billion in non-oil trade with over 170 nations last year, importing smartphones, auto parts, and grain. China remains Iran's top customer, purchasing 90% of its oil exports in 2024, worth $31.5 billion. Iran's economy has adapted to decades of sanctions by boosting domestic production in automobiles, steel, electronics, and pharmaceuticals.

Analysts are divided on the blockade's effectiveness. While it will squeeze Iran's already hobbled economy and could prompt further negotiations, it risks disrupting global oil supplies and pushing up prices. Iran has threatened retaliation by choking off other shipping traffic beyond the Strait of Hormuz. The blockade removes roughly 2 million barrels of Iranian oil daily from the market, though experts predict only a moderate impact on global oil prices.
