Brent Has Held $110 for Three Weeks. The Floor Is OPEC+ Spare Capacity

Three weeks above $110 is not a coincidence, and it is not demand. Brent settled near $113.40 a barrel on Friday, off 0.8% on the day but up about 1.1% on the week, with WTI near $100.50 and the transatlantic spread at $12.90. Front-month spreads remain in backwardation. What has held the floor is a supply curve that has stopped responding to price — OPEC+ output is running roughly 1.2 million barrels a day below its own announced ceiling, according to tanker-tracker estimates, and there is no visible mechanism to close that gap quickly.

The compliance story is more complicated than the headline. Several members are producing below quota for reasons that have nothing to do with discipline — field decline, investment shortfalls, sanctions-adjacent logistics — which means the group's spare capacity is concentrated in fewer hands than the quotas imply. That concentration is what makes the floor credible: the producers who could add barrels have little incentive to do so into a market already pricing geopolitical risk, and the ones who would like to are unable to.

Inventories confirm the tightness rather than cause it. US crude stocks fell 8.6 million barrels in the latest weekly report, a surprise draw that kept the front end bid straight through the employment data. Distillate is the tighter market: heating-oil stocks sit about 8% below the five-year average with winter demand still ahead, and cracks widened through October even as crude flatlined. Product supplied over the past four weeks is running slightly above its five-year seasonal average — consumption is not collapsing, it is rotating from goods to services and from gasoline to middle distillates.

The week ahead offers two tests. The OPEC+ technical committee meets midweek with no policy change expected, but the compliance table it publishes will be read closely for any sign that the shortfall is narrowing. The EIA report on Wednesday lands the same morning as ISM services, which means the demand signal and the supply signal arrive together — the one configuration that has historically broken this kind of range.

The range is $110 to $116 and it has held since mid-October. A break higher needs supply disappointment and a prices-paid print above 58 in the same week; a break lower needs a demand shock large enough to overwhelm a 1.2 million barrel a day shortfall, which is not what a 125,000 payroll print describes. The base case is more of the same: a geopolitical premium that decays slowly, a floor defended by incapacity rather than strategy, and a market that will not price a recession until it sees one in the inventories.
