Societe Generale analysts Michael Haigh and Jeremy Sellem report a significant divergence between physical Brent and futures prices, with Dated Brent trading at a substantial premium. The analysts highlight that diesel market strength implies Brent should be priced above $150 per barrel to restore historical refining economics, underscoring the impact of product tightness on crude markets [1].
The report notes that Brent crude recently climbed to nearly $110 per barrel as geopolitical risks intensified following attacks on Saudi energy infrastructure on September 10. During this period, 10-year Treasury yields breached 5%, and political efforts were made to stabilize oil prices and end ongoing conflict, which contributed to market volatility [1].
A key market development is the surge in the Dated Brent premium, which in September 2026 exceeded $20 per barrel—one of the highest levels in the past decade. This premium, which typically fluctuates around zero except during major supply disruptions, expanded sharply from about $3.5 per barrel in August to over $21 per barrel by mid-September, as Dated Brent rose from roughly $92 to $127 per barrel and front-month Brent increased from approximately $89 to $105 per barrel [1].
Societe Generale emphasizes that the crude price paid by refiners is now materially higher than the headline Brent price, reflecting a growing premium for immediate physical availability—a classic sign of tightening prompt balances. The analysts argue that the restoration of the historical relationship between diesel and Brent prices has been a major driver of the recent catch-up in crude prices relative to refined products. They caution that as long as the conflict persists, crude scarcity is likely to converge with the diesel scarcity already priced into the market [1].
CONCLUSION
Societe Generale's analysis points to a highly tight oil market, with physical Brent commanding a record premium over futures due to diesel strength and supply disruptions. The market is signaling that Brent prices may need to rise further to restore traditional refining economics, especially if current geopolitical tensions and product shortages persist.
