Goldman Sachs says the diesel market is now the largest threat in oil markets, with global refining throughput down as much as 6.5 million bpd versus July 2025. Global diesel exports have fallen about 35% this month, and inventories are below seasonal averages.
A sharp drop in global diesel exports and low inventories tighten fuel supply and raise prices for transport, drying and freight. The outlook points to further tightening if supply is squeezed again.
