WTI hits $100.50 as Iran tanker attacks threaten supply: Oct 20, 2026

WTI rose above $99.00 and posted a fresh monthly high near $100.50 as Iran warned of a wider blockade and continued attacks on oil tankers, with Brent topping $110 and oil hovering near a five-month high on threats to Persian Gulf supply and supply recovery around Hormuz and Houthi attacks. A US-Iran compromise proposal later raised hopes of de-escalation and triggered a sharp pullback, while Brent was also reported down over 3%, and rising oil prices were noted as weighing on risk sentiment.
