Key Takeaways

U.S. stocks tumbled on Monday as oil prices surged above $100 a barrel due to the ongoing war in Iran, which has disrupted global oil supply through the Strait of Hormuz.

  • U.S. stock markets experienced significant declines with the S&P 500 sliding by 88 points and the Dow Jones dropping over 600 points.
  • Oil prices surged past $100 a barrel for the first time since 2022, with Brent crude reaching $102 and West Texas Intermediate hitting $99.49.
  • The national average gas price in the U.S. rose to $3.48 per gallon, up from about $3 a week ago.
  • Experts warn of potential stagflation and economic impacts similar to the 1970s energy crisis due to disruptions in oil supply through the Strait of Hormuz.

U.S. stocks tumbled on Monday as oil prices surged above $100 a barrel, driven by the ongoing war in Iran and its impact on global oil supplies.

The S&P 500 slid 88 points, or 1.3%, to 6,652 in early trading, while the Dow Jones Industrial Average plunged 632 points, or 1.3%, to 46,870. The Nasdaq Composite also fell by 1.3%. Financial markets have been volatile since the war in the Middle East started last week.

The surge in oil prices was triggered by disruptions in shipping through the Strait of Hormuz, a vital waterway for oil tankers, which is at a near standstill due to the conflict. About 20% of the world's oil supply flows through this strait.

The national average gas price in the U.S. rose to $3.48 per gallon, up from about $3 a week ago and $2.90 a month ago, according to AAA. Higher energy prices are leading Americans to pay more at the pump and renewing fears of inflation.

Experts warn that this oil shock could lead to a 1970s-style stagflation scenario if shipping through the Strait of Hormuz does not resume. The disruption is also affecting various industries, from agriculture to petrochemicals.
