Global diesel crisis turns oil refineries into profit machines
A global diesel shortage is driving record profits for oil refiners. TotalEnergies reported a $1.8B increase in refining income, while US refiners like Marathon Petroleum, Valero Energy, and Phillips 66 saw valuation gains. Shell expects refining margins to reach $42 per barrel. The International Energy Agency warns of persistent shortages and potential economic impacts.
