Shell forecasts $42 refining margin per barrel — The Guardian
Shell predicts its oil refinery profit margins will reach $42 per barrel in Q3 2026, up from $24 in Q2 2023 and a previous high of $28. The increase is attributed to higher fuel prices and reduced supply due to refinery shutdowns. Brent crude averaged $85.60 per barrel in Q3, down from Q2 but up from the previous year. Diesel prices surged over $100 per barrel above the global benchmark.
