The sharpest weekly gains in United States energy were in natural gas liquids, not crude. Propane rose 0.223 dollars, or 21.0 percent, in the week to Friday on strong United States export demand and inventory draws, according to Morgan Downey’s weekly commodity review. Normal butane rose 0.310 dollars, or 18.0 percent, on domestic gasoline blending demand and tighter supply, and ethane rose 0.034 dollars, or 11.3 percent, on export capacity expansion and new cracker demand. Isobutane rose 0.197 dollars, or 10.6 percent, on tight supply and high downstream dehydrogenation demand.
The moves stand out against the headline barrel. Over the same week Brent settled lower in the current front month series carried in the site tables, and Henry Hub’s near 10 percent weekly gain was itself driven more by positioning than by physical pull. The NGL moves, by the review’s account, are physical: exports and blending demand drawing on inventories.
Propane is the one with a household consequence. The heating season is starting, and a 21 percent weekly rise in the wholesale price ahead of winter is the kind of move that shows up in delivered heating bills in the Northeast and Midwest if it holds. Whether it holds depends on the same export pull continuing against winter domestic demand.
