US EIA Distillate Stocks Change (Aug/28) 0.796M vs. Exp. -1.3M (Prev. -2.228M)

The swing from a sizeable draw to a modest build across consecutive weeks is a pattern that has tended to reflect either a step-up in refinery runs or softening implied demand, and the accompanying production and run-rate lines in the same report usually settle which side is doing the work. Single-week surprises of this size have a record of being partly revised or reversed in subsequent prints, so the established read is direction first, magnitude second. The distillate complex matters beyond the headline because it feeds directly into the ULSD crack and, through the product slate, into crude runs; a persistent string of builds has historically capped refinery margins and, at the margin, crude intake. Worth noting is where this falls seasonally, since distillate builds ahead of heating season carry a different signal than mid-season builds. The follow-ons are the product-supplied demand proxy within the report and whether the next API and EIA prints confirm the turn.
