Refining Runs Lag; Diesel Leads the Squeeze
Global refining activity for this point in the year is tracking at its lowest since 2020, leaving middle distillates at the center of a tightening product balance. Goldman Sachs characterises diesel as “at the epicenter” of the current fuel supply crunch, citing war-induced refinery outages in the Middle East and Russia that have materially curtailed output. The disruption has narrowed the margin for error heading into the latter part of the northern-hemisphere summer, when industrial and transport demand typically keeps distillate consumption resilient.
Distillates underpin road freight, construction, agriculture and marine bunkering, making availability a key determinant of broader energy costs. With global runs constrained, the shortfall has manifested most acutely in diesel, where lost barrels are not being fully replaced elsewhere in the system. The bank points to a collapse in regional output at affected sites, reducing export availability and tightening regional product flows.
Regional Offsets Fall Short
Increased throughput in parts of the Americas and Africa has helped, but by Goldman’s assessment has only offset about one-third of the lost supply tied to the outages. That leaves a net deficit in diesel production versus typical seasonal patterns. The imbalance is notable given that new refining capacity additions in recent years were expected to loosen product markets; instead, unplanned interruptions have overwhelmed incremental gains in some regions.
With the Atlantic Basin and Mediterranean often relying on interregional trade to balance diesel needs, reduced shipments from disrupted hubs can strain supply chains. Replacement cargoes may need to travel longer routes, elongating resupply times and raising the system’s sensitivity to further shocks. Any delay to restart schedules at affected refineries would prolong the strain.
Market Watchpoints
Market participants are focused on the pace of refinery restarts in the Middle East and Russia, the stability of operations elsewhere, and whether higher utilization rates in the Americas and Africa can be sustained. Export flows, especially of ultra-low sulfur diesel, remain a key gauge of how quickly regional tightness may ease. Seasonal maintenance windows, feedstock quality, and hydrogen availability for hydrotreating all factor into near-term diesel yields.
While gasoline and jet fuel demand also influence refining slates, the current configuration leaves middle distillates as the pivotal product for balancing margins and crude runs. If runs remain constrained for seasonal norms, product inventories could stay under pressure, keeping logistics and industrial users attentive to diesel procurement and timing.
Sustained tightness in energy markets can influence headline inflation, a macro variable closely tracked by holders of allocated physical precious metals.
