Tensions between Israel and Iran have reignited the threat that Iran might take the drastic step of closing the Strait of Hormuz—a move that could rattle global energy markets and draw direct U.S. and Western intervention.
On June 13, Iran's official news agency IRNA warned that if Israeli attacks on its military and nuclear facilities continue, Tehran will consider “painful steps”—including closing the strait and targeting U.S. interests in the Gulf.
Roughly 20% of global oil and one-third of liquefied natural gas pass through the strait, making it a vital energy artery. Israeli defense officials warn that even a temporary closure could damage Gulf economies and spike energy prices, inflation, and global trade imbalances.
The threats follow Israeli strikes since June 13 that killed top Iranian commanders, including Chief of Staff Mohammad Bagheri and IRGC head Hossein Salami, and hit nuclear facilities at Natanz and Parchin. Iran retaliated by launching barrages at Israeli cities, causing casualties and damage.
