Refined-product stress
Updated
What it is
Refined-product stress refers to tightness specifically in gasoline, diesel, and jet-fuel markets, as distinct from stress in crude oil itself. It is commonly measured via inventory levels versus their five-year seasonal average and via "crack spreads" — the price difference between a refined product and the crude oil used to make it — which widen when product markets are tighter than crude markets. The EIA publishes weekly U.S. distillate (diesel/heating oil) and gasoline stock data as part of its Weekly Petroleum Status Report.
Why it matters lately
U.S. distillate (diesel) inventories ran well below seasonal norms through 2026, reaching about 12% below the five-year average on August 7, 2026 (lowest comparable level in at least five years) and widening to roughly 14% below average by August 21, 2026, even as refiners ran near-record utilization rates above 97%. Refined-product cracks widened sharply during 2026's Iran-war escalations: Europe's gasoil crack spread hit its highest level since August 2023 and the U.S. diesel-vs-WTI crack spread rose to roughly $70/barrel, with China's halt of diesel/gasoline exports adding further support to global product cracks.
Asymmetric Analytics view
Inference (AA): It is the product-market-specific stress variable AA tracks separately from crude price, since diesel/jet shortages can bite the real economy even when crude supply looks adequate.
