Iran warns of ‘devastating’ response to impending US sanction barrage
The U.S. has implemented a naval blockade that has significantly reduced Iran's crude oil exports, trapping millions of barrels in the Persian Gulf. This economic pressure threatens a major source of Iranian government revenue as the Trump administration prepares for further sanctions.
Why it matters
The disruption of Iranian oil exports impacts global energy markets and escalates geopolitical tensions between the U.S. and Iran.

Iran has loaded an average of roughly 287,000 barrels per day of crude so far this month, down from about 2 million barrels per day before the war, according to data from commodities intelligence firm Kpler.
China, Iran's biggest oil customer, has received about 523,000 barrels per day of Iranian crude this month, compared with more than 1.7 million barrels per day at the beginning of the war.
