# Biodiesel boom drives soybean oil to 4-year high

> Soybean oil prices hit their highest level in over four years in June 2026, driven by surging biodiesel demand tied to the RFS 2026-2027 volume requirements. Soybeans recently topped $11 per bushel for the first time in two years, and a new Gilman, Illinois processing plant was highlighted. Oil refiners and environmental groups are challenging the EPA volume requirements in court.
