US diesel refining margin (diesel crack spread) has surged above $100/bbl, a record level amid tightening global fuel production. The diesel crack hovered around $100/bbl on Tuesday, slightly below a prior peak above $102/bbl; it first closed above $100/bbl on Monday. Before this year the metric had never exceeded $89/bbl; the previous record was set in October 2022 during a diesel shortage ahead of winter. A combination of factors has created a near "perfect storm" pushing diesel prices higher

US diesel refining margin (diesel crack spread) has surged above $100/bbl, a record level amid tightening global fuel production. The diesel crack hovered around $100/bbl on Tuesday, slightly below a prior peak above $102/bbl; it first closed above $100/bbl on Monday. Before this year the metric had never exceeded $89/bbl; the previous record was set in October 2022 during a diesel shortage ahead of winter. A combination of factors has created a near "perfect storm" pushing diesel prices higher and may lift winter heating costs and add renewed inflationary pressure.
