Oil prices spiked and stocks tumbled worldwide in early trading on Thursday as Iran escalated attacks on shipping in a critical tanker route. Global crude prices surged above $100 per barrel, defying a U.S. effort to reassure markets with a major release from the nation's petroleum reserve. A selloff hit Wall Street as traders feared economic fallout from a potentially prolonged period of elevated oil prices.

Why it matters

The Strait of Hormuz is a crucial global oil trading route, facilitating the transport of about one-fifth of the world's crude supply. Disruptions to this chokepoint could have far-reaching economic consequences, impacting energy prices, stock markets, and the broader global economy.

The details

Iran has been accused of carrying out a series of attacks on oil tankers passing through the Strait of Hormuz, a strategic waterway that connects the Persian Gulf to the Gulf of Oman. This has led to a major supply shortage, driving up global crude prices. The U.S. government attempted to ease market concerns by announcing the second-largest ever release from the country's strategic petroleum reserve, but this failed to stem the price surge.

  • On Thursday, March 12, 2026, oil prices surged above $100 per barrel.
  • Earlier on the same day, the U.S. government announced the release of oil from the strategic petroleum reserve.
