United States–Iran relations deteriorated further over the weekend as the two countries exchanged missile fire, with at least one commercial vessel struck in the Strait of Hormuz. Iran declared the vital waterway closed to shipping after the attacks, disrupting tanker movements and slowing traffic through one of the world’s most important oil transit routes to a trickle. A US official said American forces conducted a fresh round of strikes on Iranian targets on Sunday, the third such action in a week, underscoring the collapse of a previously fragile cease-fire between the two sides and fueling renewed fears over maritime security in the Gulf. Global oil markets reacted nervously to the escalation, with Brent crude prices swinging sharply as investors assessed the risk to supplies. Brent, which had previously retreated to a range of $72 to $75 a barrel after peaking at $188 in April when the conflict intensified, spiked as high as $78.19 before easing back toward $76.01 by Friday. The renewed conflict has disrupted shipping in the Gulf, raised concerns over global energy security, and added to inflationary pressures highlighted by the Federal Reserve, which warned that continued interference with Strait of Hormuz shipping is pushing up gasoline and industrial energy costs and feeding through the broader US industrial chain.
