Why has Henry Hub natural gas fallen 5.2% to 2.773 this month?
Henry Hub natural gas is 2.773, down 5.2% over the past thirty days, off a high of 3.343. A fuel operator watching that number wants two things from it: why it fell, and whether it changes anything they pay for. I went at both.
The first place to look for a falling gas price is how much gas is sitting in the ground. Working gas in storage is 3169, up 3.7% over the month, climbing toward its 30-day high of 3364. A second storage series our desk tracks tells the same story, up 7.3% to 107.013. When the volume in storage builds week after week, it means gas is going into the caverns faster than it is being pulled out, and a market with more supply than it can burn prices that gas cheaper. The storage build and the price fall line up. On the simplest reading, that is the whole answer: injection season is doing what injection season does, and Henry Hub softened because the country is well supplied.
The more useful question for an operator is whether a cheaper gas price drags the rest of their fuel bill down with it. So I checked the products they actually move. ULSD diesel futures are 4.495, up 8.3% on the month, and that 4.495 is the 30-day high. Retail diesel is 5.454, up 6.2%. Both went up while gas went down. Whatever pulled Henry Hub lower did not reach the diesel market. The two moved in opposite directions this month, and by a wide gap in words, gas off about a twentieth while diesel gained close to a tenth.
If diesel is climbing, the next thing to check is who is earning that climb. The 3:2:1 crack spread is 69.61, up 2.75 over the month. A wider crack means refiners are getting more for turning a barrel of crude into gasoline and diesel than they were thirty days ago, and that is a good stretch for the plants still running at full rate. The retail-wholesale diesel spread barely moved, 1.017 now, up 0.002. The money in diesel this month showed up upstream at the refinery gate, not in the margin between the rack and the pump. A retailer is paying more for product and passing most of it through, earning about what they were before on each gallon.
That split told me the diesel move and the gas move are two separate stories, so I went to the wire to find the diesel one. It is on the refining side, and a lot of it is physical. Ukrainian drones hit the Novokuibyshevsk oil refinery in Russia's Samara region overnight on August 22, sparking a fire; the plant is a Rosneft facility with capacity of roughly 8.8 million metric tonnes of crude a year, turning out more than 20 products including diesel and aviation fuel. Rigzone reports US refiners facing an import crunch from a top crude seller. Take barrels of refining capacity offline in one place and squeeze crude supply in another, and product tightens and the crack widens, which is what the diesel and crack numbers show. None of that has anything to do with how much natural gas is in a US storage cavern.
One number complicated the tidy version. U.S. petroleum inventories are 428.815, up 4.2% over the month, which sounds like plenty. But that figure is well below its 30-day high of 465.729, so total petroleum stocks have come off their peak even as the month-over-month change reads positive. Stocks drawing down from a high while the crack widens fits a market where product demand and refinery outages are pulling harder than supply is refilling. It points the same way the diesel price does. The gas market and the oil-and-products market are not on the same cycle right now.
So the honest answer to the headline. I am fairly confident on the why: Henry Hub fell because storage is building, gas is going in faster than it is coming out, and a well-supplied market prices lower. The storage series back that up, and it is the ordinary reason gas softens in this part of the year. I am more cautious calling where it goes next, because a hot stretch or an early cold snap can pull the same storage back down and take the price with it, and I will not call a direction on weather I cannot see.
On what it means for a fuel operator, the plain finding is that for most of them, this month, it means very little. If the business is hauling and selling diesel, Henry Hub at 2.773 did nothing to help; diesel got more expensive at the same time, and the reason sits in refinery outages and crude supply, not in the gas market. The cheaper gas matters to a narrower group: fleets running compressed natural gas, and refiners and terminals whose own process heat and power run on gas, since their input just got a little cheaper while their product sells for more. For anyone moving liquid fuel, the number to watch this month is the crack at 69.61 and the diesel futures at 4.495, not Henry Hub. The gas drop is real, and it is mostly a different market's story.
And that was just the data. See you tomorrow.
