Why has WTI crude climbed 5.1% in a month to 99.42?
WTI crude is 99.42, up 5.1% over the past month, and a buyer looking at that print wants to know whether it's a reason to lock in now or a number set to come back down. I pulled the full board of benchmarks to see what is actually pushing it.
Brent is up 12.8% over the same 30 days, more than double WTI's move. Brent is 111.98 right now, which is also its 30-day high, so it is at the top of its range. WTI is 99.42, below its own 30-day high of 105.83. Both are up, but the international grade is leading and WTI has already come off its peak. That gap is the first clue, because it says the pressure is not landing evenly on the two grades.
The wire explains why. Brent held above $111 after Houthi attacks on Saudi targets, with the U.S. government ordering non-emergency personnel to leave the kingdom. Separately, Kpler data cited by the Wall Street Journal has Iranian oil in floating storage drained to near nothing under a U.S. naval blockade that began in April, when Iran held close to 150 million barrels. The supply leaving the market is Middle Eastern, routed through the Strait of Hormuz, which is Brent's neighborhood more than WTI's. A seaborne shock lands on the waterborne benchmark first, and WTI, priced inland at Cushing, feels a softer version of it.
Demand is pulling the same direction. India's crude imports from the Middle East jumped to 2.8 million barrels per day in September, up 32% from August and the highest since February. Buyers are drawing barrels through Hormuz at the same moment the security headlines say that route is contested. Tight supply plus firm pull is a clean reason for crude to rise, and it mostly rises on the grade closest to the trouble.
Then the products, where the obvious read breaks. If crude is up, you would expect gasoline and diesel to follow. They went the other way. RBOB gasoline is 3.104, down 11.0% over 30 days. ULSD diesel is 4.721, down 4.5%. Crude firmed and fuel fell.
The crack spread carries the same message. The 3:2:1 is 53.58 now, down 18.67 over the month. A refiner buying WTI and selling gasoline and diesel saw that margin compress hard as the crude side rose and the product side eased. The month rewarded the barrel in the ground, not the barrel turned into fuel.
Part of the product softness is the calendar. Gasoline demand eases past summer, and RBOB's 30-day low of 2.839 shows how far it has already traveled off the top. Rosneft refinery attacks and sanctions are a supply problem for Russian product, but the U.S. product picture in this data is looser, not tighter. Crude scarcity overseas and ample product at home can sit side by side, and this month they did.
For a fuel operator the useful part falls out of that split. Your wholesale cost for gasoline and diesel came down this month even as the crude headline went up. The diesel retail-wholesale spread is 1.356, down 0.283 over 30 days, so the gap between what retailers pay and what they charge for diesel narrowed. Wholesale did not fall as fast as the pump, or the pump came down to meet it. Either way, the retail diesel margin is thinner than it was a month ago, and the gasoline buyer is paying meaningfully less at the rack than in early autumn.
Natural gas is not part of this story, and it is worth confirming that rather than assuming it. Henry Hub is 2.753, down 7.2%, and storage is 3567, up 8.2% and at its own 30-day high. Plenty of gas in the ground and a soft price. No crude signal reaches over from that market.
So the honest answer. WTI's 5.1% is real, and it is the smaller half of a Middle East supply scare that is hitting Brent far harder, with WTI already slipped below its 30-day high. I am sure the driver is supply-side and offshore, Houthi strikes and the Iran blockade and firm Asian buying, not a surge in U.S. demand. I am not sure it holds, because the thing moving it is a security situation that could ease or worsen on short notice, and a benchmark pushed up by headlines can give the gain back the same way.
What I would act on is the part the data settles. Crude up and product down is the month that happened, and the two did not move together. If you buy product, your costs eased this month and the crack tells you the refiner absorbed the squeeze between the two. If you refine, the margin thinned and the reason is the crude you feed got dearer while the fuel you sell did not. The number to watch from here is Brent and the Hormuz traffic, because that is what is actually setting the direction, and WTI is following it at a distance. Locking in product cost off a scary crude headline would mean buying a rise that, so far, has not shown up in the fuel.
And that was just the data. See you tomorrow.
