Stocks of crude oil in the US SPR fell by about 3.1mln barrels to 286.6mln barrels last week.

A draw in the Strategic Petroleum Reserve differs from a commercial inventory draw in that it reflects policy rather than refinery demand or supply tightness, and the two have historically carried opposite read-throughs: commercial draws tighten the physical balance, while SPR releases add barrels to the market and have tended to be read as mildly bearish for flat price at the point of delivery. Episodes of sustained reserve depletion have mattered less for their weekly prints than for what they signal about the government's stance, both as a supply management tool during price spikes and, once stocks fall far enough, as a future source of demand through refills, a dynamic that has at times put a floor under deferred spreads. The distinction worth drawing is between scheduled sales or exchanges and discretionary policy action; the former is largely priced, the latter is what moves sentiment. At these levels, the market tends to focus on the refill question, since any announced purchase programme effectively adds a government bid to the WTI complex. The follow-ons worth tracking are the weekly commercial inventory data from the same reporting period, any official commentary on replenishment, and whether the release rate is accelerating or winding down.
