S&P Global warns diesel market faces ‘winter is coming’ crisis

The world is entering fall with fuel stockpiles at their thinnest in years, and the outlook is getting worse. Global gasoline stocks began September at their lowest tracked levels for any month in at least a decade, while diesel prices in both Europe and the United States have surged to record highs, according to a new analysis from S&P Global Energy. The warning arrives as harvest season ramps up in the Northern Hemisphere and winter heating demand approaches — a convergence analysts say leaves almost no room for further disruption.rigzone

A Tightening Vise on Diesel

U.S. distillate inventories, the category that includes diesel and heating oil, fell to 103.4 million barrels for the week ending August 21, the lowest level ever recorded for that time of year, according to the Energy Information Administration. The EIA has forecast that distillate stocks could drop below 100 million barrels and remain near five-year lows through 2027. Gasoline inventories, while less dire, sit roughly 6 percent below their five-year average.post-register+1

S&P Global Energy ↘ 0.65% now expects global diesel crack spreads — a measure of refining profitability — to average about $84 per barrel through the rest of 2026, a $31 per barrel increase from its prior forecast. Ole Hansen, head of commodity research at Saxo Bank, noted that European gasoil and New York ultra-low sulfur diesel recently traded at roughly twice the price of Brent crude, with U.S. retail diesel reaching a record above $6 per gallon.rigzone

The squeeze has been compounded by a collapse in global refining capacity. Refinery runs in August were down more than six million barrels per day compared to the prior year, S&P Global reported, driven largely by disruptions in the Middle East and Russia. Russia's ban on diesel exports has already removed roughly 10 percent of waterborne supply from global markets. U.S. refineries, meanwhile, have been running at about 97 percent of operable capacity — near their practical ceiling.post-register+1

Geopolitical Shocks Add Pressure

The precarious supply picture worsened after drone attacks from Iraqi territory forced Saudi Arabia to shut its East-West pipeline, a conduit capable of moving roughly four million barrels per day. Repairs could take three to five weeks, according to officials briefed on the damage cited by the Associated Press. Brent crude climbed above $107 a barrel in the aftermath, while U.S. crude moved above $102.cnn+3

Costs Ripple Through the Economy

The pain extends well beyond the pump. Reuters reported that fuel surcharges on U.S. grain shipments by rail have climbed 153 percent from a year ago, now accounting for roughly 11 percent of rail transportation costs for corn and soybeans as fall harvest begins. The International Energy Agency has described the broader situation as an "unprecedented disruption to global fuel markets".iea+1

Karim Fawaz, executive director at S&P Global Energy, warned that "policymakers may soon face uncomfortable tradeoffs" between protecting consumers, preserving energy security, and keeping trade flows open. "The longer this disruption lasts," he said, "the harder those choices become."rigzone
