US EIA Refinery Crude Runs Change (Aug/21) -0.002M (Prev. 0.216M)

Refinery crude runs are one of the steadier lines in the weekly EIA report, and a flat-to-marginally-negative change after a sizeable build in throughput the prior week is typical of the late-summer pattern, when utilisation plateaus ahead of autumn maintenance turnarounds. The runs figure matters less on its own than as the demand-side counterpart to the crude draw or build: a near-unchanged runs print means the crude balance line, not refiner appetite, will do the work in this report. WTI's reaction to the weekly numbers has historically been driven by the surprise in the headline crude and product stocks rather than by runs, with moves on runs-only surprises tending to fade quickly. The points of interest are whether utilisation confirms the seasonal rollover into maintenance season and whether product builds accompany the flat runs, which would argue for softer margins ahead. As a single weekly print, this is noise unless it starts a trend.
