Washington DC, July 16 -- Disruptions to international crude oil and petroleum product flows through the Strait of Hormuz during the second quarter of 2026 boosted U.S. refinery margins, production and petroleum exports, according to the U.S. Energy Information Administration (EIA).

The EIA said petroleum markets in the second quarter of 2026 were marked by continued disruptions to international crude oil and petroleum product flows through the Strait of Hormuz, which contributed 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," the EIA said....
