Oil prices spiked above $100 per barrel on Thursday as Iran escalated attacks on shipping in the Strait of Hormuz, a critical global oil transport route. The surge in oil prices triggered a selloff on Wall Street, with the Dow Jones Industrial Average falling over 550 points and the S&P 500 and Nasdaq also declining.

Why it matters

The Strait of Hormuz is a vital global oil chokepoint, facilitating the transport of about one-fifth of the world's crude supply. Disruptions to this route can have significant ripple effects on energy markets and the broader economy.

The details

Despite a U.S. effort to calm markets by announcing the second-largest ever release from the nation's petroleum reserve, oil prices continued to surge. Global crude settled slightly below the $100 per barrel benchmark, defying the administration's intervention. The stock market selloff was driven by fears of prolonged economic fallout from elevated oil prices.
