US-Iran fighting keeps pushing oil prices higher — and they don't fall back

Oil prices jumped in the week ending September 7, 2026: Brent up 7.8%, WTI up nearly 10%. The US and Iran resumed attacks on ships near the Strait of Hormuz, a narrow channel that carries major oil supply. Each clash since mid-August pushed prices up, and they never fully dropped back. Brent went from the high $80s to over $100.
