Why did Henry Hub natural gas climb 11.7% to $2.996/MMBtu this past month?

Henry Hub natural gas is $2.996/MMBtu, up 11.7% over the past thirty days. Operators who buy gas for process heat or run gas-fired equipment want to know whether that is the front edge of a bigger move or the tail of one. So I pulled the rest of the energy stack to see where gas fits.

The first number cut against the easy read. WTI crude is $92.46/bbl, up 22.0% over the same thirty days. Brent is $96.77/bbl, up 21.9%. ULSD diesel futures are $4.484/gal, up 18.9%. Gas rose about half as much as crude. If this were one broad energy rally lifting everything together, gas would move closer to oil. It moved the least of the four.

The gap matters because it tells me the gas climb is probably not just crude dragging the whole complex up. Crude and gas trade on different supply and demand. When they diverge this far in a month, the gas story is at least partly its own.

I looked next at where gas stands inside its own range. Henry Hub's thirty-day high is $3.343/MMBtu and its low is $2.64/MMBtu. At $2.996 it is closer to the top of that band than the bottom, and it is already off the high. The climb is real and it has started to ease.

The wire gave me thin material on Henry Hub itself. The natural gas coverage that surfaced is propane, which trades in the gas-liquids complex rather than at Henry Hub, so I treat it as a neighbor. RBN Energy reported a counterseasonal draw that trimmed U.S. propane stocks as exports and product supplied increased, with stocks still well above historical levels. Exports pulling product out of storage is a demand story. If the same export pull is reaching the broader gas complex, it could be part of what lifted Henry Hub. I cannot prove that link from this data. The one piece of gas-side reporting I have points to demand leaving the country through exports.

Then I checked what the crude move is doing downstream, because that is where most operators actually feel price. The 3:2:1 crack spread is $52.51/bbl, down 4.37 over thirty days. Refiner margin on turning crude into products narrowed this month even as everything got more expensive. Crude rose faster than the diesel and gasoline that come out of it. Refiners are earning a solid margin at $52.51/bbl, just less than they were a month ago.

Wholesale diesel has climbed far faster than retail. ULSD diesel futures are up 18.9%. U.S. diesel at the pump is $5.599/gal, up 4.7%, roughly a quarter of the wholesale move. The diesel retail-wholesale spread is $1.104/gal, down 0.367 over thirty days. Marketers who buy wholesale and sell retail saw that cushion shrink. When the pump price catches up to the board, some of that spread could come back, but right now the people between the rack and the customer are carrying the fast part of the move.

Inventories give me one more read. U.S. petroleum inventories are 424.46 million barrels, up 4.3% over thirty days, off a high of 465.729 and above a low of 404.508. Stock built while crude prices rose, which is not the picture of a market short of barrels. A price rally on rising inventory usually points to something other than domestic scarcity doing the pushing.

So what does the 11.7% gas move mean for fuel operators. Gas rose, but it rose the least of the major benchmarks, so an operator watching input costs is absorbing a bigger hit from crude and diesel than from gas. The climb has already come off its thirty-day high, so at $2.996/MMBtu the front edge of the move appears to be behind rather than ahead, though I would not call direction with confidence. The one gas-complex data point I have, the propane draw, points to export demand rather than a domestic supply problem, which is a demand I can watch but not one that forces a hard local shortage.

What I am not sure of is the cause of the Henry Hub move itself. The data desk gives me the size, 11.7%, and the range, but the wire did not hand me a Henry Hub supply or weather story to hang it on. I am not going to invent one. Gas rose along with the rest of the energy complex, led by crude. Some of the move may be its own, and export pull is one thing that could account for that. It also stopped short of its recent high. An operator hedging gas cost for the next quarter has room to treat this as a moderate climb off a low base rather than a signal of scarcity.

For the operator between wholesale and retail, the crack spread down 4.37 and the retail-wholesale diesel cushion down 0.367 are where this month changed who earns what. Refiners kept a good margin, and marketers gave some of theirs back.

What to watch: exports and storage. If the export pull that drew down propane is reaching the broader gas complex, that is what would keep Henry Hub firm. If it eases, a gas price already off its high has more room to slip than to run.

And that was just the data. See you tomorrow.
