Oil prices jumped more than 6% and stock futures pointed to a 1% decline on Monday as renewed conflict between the U.S. and Iran in the Strait of Hormuz dampened hopes of a peace deal. The U.S. Navy seized an Iranian cargo ship, and Iran reasserted control over the vital oil shipping route, leading to concerns about further supply disruptions.

Why it matters

The Strait of Hormuz is a critical global chokepoint for oil and natural gas shipments, with around one-fifth of the world's oil supply passing through the narrow waterway. Any disruption to shipping in the region can have significant ripple effects on energy prices and the broader economy.

The details

On Sunday, a U.S. Navy destroyer attacked and seized an Iranian-flagged cargo ship that the U.S. said had tried to evade the blockade on ships traveling to and from Iranian ports. Additionally, Iran reversed course on Saturday, reasserting 'strict control' over the Strait of Hormuz and attacking two Indian-flagged vessels. These developments came after markets closed on Friday, leaving traders to digest the renewed tensions.
