US Private Inventory Data (bbls): Crude +2.7mln (exp. -2.0mln), Distillates -1.2mln (exp. -0.1mln), Gasoline +0.2mln (exp. -1.3mln), Cushing +2.4mln

This is the private industry survey, the advance signal for the official government release that follows it the next morning, and the established pattern is that the crude line only carries lasting weight if the official data confirm it; divergences between the two prints are common enough that desks treat this as a positioning input rather than a trading verdict. The surprise here is broad: a crude build against an expected draw, and the same direction in Cushing, which matters separately because it is the delivery point for the WTI contract and its tank levels feed directly into the front spread and the shape of the curve. A build at the hub against expectations is the combination that has historically pressured prompt timespreads toward contango more reliably than the headline crude number alone moves the flat price. The products split against the crude signal, with distillates drawing harder than forecast while gasoline built against an expected draw, so the refined market is giving a mixed read on demand rather than a clean bearish one. The follow-ons are the official print, refinery utilisation within it, and whether the crude build is an artefact of imports or exports shifting week to week, which is the usual explanation when these surprise builds partially reverse.
