Oil Over $100: Why Brent Is Outpacing U.S. Crude

Brent crude rose 3.9% to $103.08 a barrel in Wednesday trading, while West Texas Intermediate settled up 1.8% at $92.16. The figures were reported by the WSJ on Sept. 24, under a headline framing trade as mixed as traders weighed U.S.-Iran talks and Saudi pipeline progress.

Brent is the benchmark for much of the world's oil. WTI is the U.S. benchmark. Both ended above $90, with Brent above $100. Brent rose by a larger percentage that day than WTI.

Those settlements followed several up-and-down sessions in September. Brent futures settled at $104.87 a barrel on Sept. 18, down 95 cents, or 0.93%, according to Reuters. U.S. West Texas Intermediate futures finished that day at $100.30 a barrel. A day earlier, oil prices had settled about 1% lower but stayed above $100 a barrel, as fears of Middle East supply disruptions eased.

Earlier in the month prices jumped. Brent crude futures settled up $6.42, or 6.34%, at $107.63 a barrel, Reuters reported on Sept. 10. U.S. intermediate crude futures rose $6.43 that session. The report linked the move to tanker attacks deepening supply fear, with Brent holding above $100. The climb started from lower levels. Brent crude futures were up $1.66, or 1.7%, at $97.29 a barrel by 1200 GMT on Sept. 3, as investors weighed uncertainty over U.S.-Iran strikes.

On supply, the International Energy Agency expected world oil supply in 2026 to decline by 5.7 million barrels per day, or about 6%, Reuters reported on Sept. 11. That assessment pointed to a deepening supply gap tied to delayed return of normal Gulf flows. Later signals pointed the other way. Asian markets started the week on a positive note helped by a drop in oil prices and reports of increased supply, according to a Sept. 21 report.

Stocks moved without a clear direction. Asian shares were mixed, with benchmarks in Tokyo and Seoul leading gains on buying of computer chipmakers, in a Sept. 7 report.

Commerzbank raised its year-end Brent crude forecast to $85 a barrel from $75, and increased its diesel forecast to $1,200 a ton from $950. Those forecasts come from an undated report and should be read as background rather than as an update to the September settlement sequence.

The broader context here is a market trading headline by headline rather than on a stable change in stored oil. Brent moved from $97.29 to $107.63 to $104.87 to $103.08 through the month, while WTI took a softer path to $92.16. The gap between spot prices above $100 and a year-end forecast of $85 shows near-term tightness that longer-term views are not carrying forward one for one.

In my view, three frictions deserve attention. First, the Brent-WTI gap in the Sept. 24 settlements keeps Atlantic basin arbitrage, buying in one region to sell in another, freight costs, and U.S. export demand in focus. Second, the distance between prompt Brent above $100 and a year-end $85 forecast means the market is pricing near-term tightness and later normalization at the same time. Whether that shows up as steep backwardation, when oil for immediate delivery costs more than oil for later delivery, episodic spikes, or a slow fall in the price gap over time will shape incentives to store oil and carry it forward. Third, the product side matters. A $1,200 diesel forecast against an $85 Brent forecast leaves implied refining strength in place even if crude falls, with direct effects for refining margins, inventory policy, and hedging tenor.

Looking at what this means for risk, the IEA figure of a 5.7 million barrel per day decline frames the tail risk, not the outcome for every session. Prices have shown they can add or shed several percent in a day on talks, pipeline headlines, tanker risk, or supply reports. That argues for treating how much to hold, protection around near-term delivery dates, and the risk that Brent-linked and WTI-linked positions move differently as first-order, not residual, concerns.
