Midwest diesel spot prices rose in June as refiners running at about 76% of capacity bought fuel on the open market to meet contracts. Regional cash differentials to heating oil futures rose about 50% since early June, even though Midwest diesel stocks are near record levels.
Refining margins have fallen to the lowest seasonal level since at least 2010.
Higher regional diesel differentials raise Midwest fuel costs for grain and feed logistics, even with ample inventories and weak refinery economics.
