Petroleum markets responded to disruptions in the Middle East in the second quarter

Petroleum markets in the second quarter of 2026 (2Q26) were characterized by continued disruptions to international crude oil and petroleum product flows through the Strait of Hormuz, contributing to higher and more volatile crude oil prices through most of the quarter. The disruptions also resulted in international buyers seeking alternative supply sources for petroleum products, driving up U.S. refinery margins, production, and exports.
