OPEC's monthly report shows July refining margins at the three major hubs (US
Gulf, Rotterdam, Singapore) rose sharply to multi-year highs. Rotterdam margins
surged $17.88/bbl MoM to $42.13/bbl, the largest monthly rise; US Gulf margins
reached $45.70/bbl, the highest since Oct 2022. The report attributes the margin
expansion to a rebound in middle-distillate (diesel) cracks after East European
refinery outages, Russia's diesel export ban and Middle East geopolitical
tensions tightened global diesel supply.
