The measures target a so-called "shadow fleet" that masks Iranian exports and include bans on associated shipping companies and finance networks, U.S. officials said.

The episode traces back to months of escalating violence across the region that intensified after the Twelve-Day War in June 2025. Widespread anti-regime protests erupted in Iran on December 28, 2025, and coordinated U.S.-Israeli strikes on February 28, 2026, killed Iran's supreme leader and hit military sites. In April 2026 the U.S. launched the "Economic Fury" campaign to choke Iran's oil revenues, and these sanctions are part of that effort.
Shipping and market effects are already visible. A Jones Act waiver extended April 24, 2026, lets foreign-flagged vessels move U.S. oil between ports and has been used to reroute flows amid a near halt of traffic through the Strait of Hormuz. PBS News Social media accounts and traders named specific Chinese refiners and shipping lines as targets and posted figures including dozens of shippers and roughly $344 million in frozen cryptocurrency tied to Iran's networks.
