The weekly prints are noisy: what has mattered in past episodes is whether the surprise aligns with the inventory trajectory over consecutive weeks and with the demand line, since implied demand revisions have often reversed one-off moves. A draw during the transition into autumn, when runs typically ease for turnaround season, is less informative than the same print in driving season, so the seasonal position shapes how much weight the number carries. The follow-ons are the crude and distillate lines from the same release for consistency, the refinery utilisation figure, and whether subsequent weeks confirm the draw rather than reverse it. As a weekly flow indicator rather than a structural signal, the established pattern is an initial crack and flat-price reaction that retraces if the next prints do not corroborate.
