Oil prices surged to a five-week high on July 21, 2026, as the conflict between the United States and Iran intensified, with U.S. forces bombing targets in southern and western Iran, and Iran retaliating by targeting U.S. sites in Bahrain, Kuwait, and Jordan, and hitting at least one tanker in the Strait of Hormuz.
