- Iran closed the Strait of Hormuz, halting Indian ship traffic and inflating global shipping costs.
- U.S. launched the "Economic Fury" sanctions campaign, targeting Iran’s oil exports and banking networks after the ceasefire.
- Trump unilaterally extended the ceasefire on April 21, citing doubts about Iran’s negotiating unity.
- M/V Blue Star III was intercepted on April 28, 2026, suspected of violating the U.S. blockade of Iranian ports.
Why it matters: Oil importers lose billions in extra shipping costs; Iran's blockade buys negotiating leverage but threatens its economy; the U.S. escalates pressure, forcing Tehran to concede on nuclear terms within three weeks.
