ExxonMobil (XOM) — threat to the moat

When the whole industry lowers its cost per barrel, the saving does not reach the shareholder — it reaches the price.

There is a trap in cost leadership in a commodity, and it is that success spreads. If ExxonMobil lowers its cost per barrel and nobody else does, it earns more. If the whole industry lowers its cost per barrel, the marginal producer survives at a lower price, supply rises, and the price falls until the marginal producer is uncomfortable again. The gain is competed away into the price.

Realised Brent, and what it did to a record year202320242025Realised Brent, $ per barrel. 2025 production was a record 4,736 kboed.
Demand set a record in 2025 and the price still fell, because industry supply rose faster.

ExxonMobil's own explanation of the 2025 price fall says this outright: lower crude prices as record demand was more than offset by increased industry supply1. Demand set a record. The price still fell, because supply rose faster — and a large part of that supply came from American shale operators doing exactly what ExxonMobil is doing in the Permian, only faster and with less capital discipline.

The risk factors put the general form of it plainly: increased supply from the development of new or previously inaccessible oil and gas supply sources and technologies to enhance recovery from existing sources tends to reduce commodity prices to the extent such supply increases are not offset by commensurate growth in demand2. That sentence describes the shale revolution, and it describes what ExxonMobil's Permian programme contributes to.

There is a second, sharper version of the problem. ExxonMobil's target is roughly 2.5 million oil-equivalent barrels a day from the Permian by 2030, up from 1.6 million3, and 5.5 million company-wide4. Nine hundred thousand barrels a day of new American supply is a meaningful fraction of the annual growth in world demand. A producer large enough to move the price is, at the margin, competing with itself.

ExxonMobil's protection is being further down the cost curve than the operators who would have to stop first. That is a real defence and it is relative, not absolute: it guarantees survival, not profit.

Industry supply growth against demand growth is what decides it — visible to ExxonMobil only through the realised Brent line, $69.06 in 2025 against $80.76 in 20245. If the company hits its 2030 volume targets and the realised price is lower than today, the cost leadership will have worked exactly as designed and earned nothing.
