Brent holds above $100 on two supply threats of unequal size
Brent rose to $101.80 on Wednesday after a Gulf storm curtailed 185,120 barrels a day of US offshore crude and Houthi strikes damaged two Saudi airports. That loss is small beside Middle East shut-ins, so the bigger fourth-quarter cost risk runs through Gulf refineries into diesel.
The Investor · Invest desk
What happened
- The EIA raised its fourth-quarter Brent forecast by $14 to a $105 average, citing constrained Middle East exports, shipping costs and shrinking inventories, The Wall Street Journal reported.
- Middle East crude shut-ins averaged 4.8 million barrels a day in September, down from 5.8 million in August and a May peak of 10.9 million, according to EIA data.
- Six refineries lie within the storm's reach, and refineries in US Gulf states hold about half of the country's 18.2 million barrels a day of capacity.
- European diesel futures traded about $77 a barrel above Brent on Wednesday morning, up 13% on the day.
- The Energy Department sought proposals to release up to 40 million barrels from the Strategic Petroleum Reserve while the IEA met informally on a new release of oil and diesel stocks.
Why it matters
- What it costs cost Diesel buyers pay for a Gulf refinery outage before crude buyers do, and the premium they already pay is about three-quarters of Brent's own price.
- Who has to decide decision Budgets holding crude at Wednesday's price sit $3.20 a barrel below the EIA's $105 quarterly average, a gap driven by inventory draws more than by the storm.
- What it limits constraint Because the 40 million barrels are the last tranche of March's 172-million-barrel drawdown, any further strategic-stock relief this quarter depends on a new IEA agreement.
- What doesn't add up contradiction EIA data show Middle East exports rising in September even as the agency raised its price outlook, so the $105 forecast assumes inventory draws outweigh the regional recovery.

Set against September's Middle East shut-ins, the storm's curtailment is about a twenty-sixth of the size [33]. At 9.2% of Gulf offshore production, it implies an offshore base of roughly 2 million barrels a day [21]. As of Tuesday morning, no personnel had been taken off platforms or rigs [3]. Forecasters expected the storm to become the season's first Atlantic hurricane within 48 hours [2].
The larger exposure is onshore. Gulf state refineries hold roughly 9.1 million barrels a day of capacity [30]. Tim Waterer, chief analyst at KCM Trade, said the storm was an "unwelcome complication for crude, raising the prospect of production and refining disruptions at a time when the market already has enough supply-side headaches" [7]. Fuel markets were already tight. Vitol chief executive Russell Hardy said strikes on Russian energy infrastructure and the loss of Middle East refining runs have tightened them [17], and Ukraine struck two Russian oil facilities on Wednesday [18]. Add the diesel premium to Brent's price at the same hour and European diesel was near $178.80 a barrel [23].
Mukesh Sahdev, chief oil analyst at X Analysts, said attacks and refinery outages are "likely to keep the cracks elevated and scarcity will transmit to crude. Prices will stay elevated near a $100 level without any material de-escalation emerging" [24].
Before its revision the EIA had the quarter averaging $91 [27]. Its own data show global stocks drawing 1.9 million barrels a day in the third quarter and 700,000 a day in this one, about 64.4 million barrels over the quarter's 92 days [22][31]. The Energy Department's offer of up to 40 million reserve barrels equals about 62% of that draw [16][28]. A week of the storm's curtailment is about 1.3 million barrels, or 2% of it [34].
The case against repricing is the pace of the Middle East recovery. Shut-ins have fallen 6.1 million barrels a day since May and 1 million in the latest month [32]. Saudi Energy Minister Prince Abdulaziz bin Salman said the East-West pipeline had reached 5.8 million barrels a day [10]. The head of Vitol said about 12 million barrels a day of crude left the region by tanker over the past 7 to 10 days [11]. "There is a clear tug-of-war at the moment between improving supply from the region and lingering threats to supply," analysts at ING said [9]. PVM's Tamas Varga said investors lack conviction that the recent rise in Middle East supply and exports is sustainable [12].
Beyond the Saudi airports, the Houthis struck Aden's airport on Wednesday, and a missile aimed at an area north of Riyadh was intercepted [4][5]. The attacks came as Saudi-backed Yemeni government forces pressed an offensive to retake territory, with Riyadh stepping up airstrikes [8]. India's foreign ministry said 12 mariners aboard the tanker MT On Peace were wounded on Tuesday, and Quartz reported that shipping risk around the Strait of Hormuz remains elevated [13].
If the storm spares the six refineries and October shut-ins fall below September's, Brent has room to drift back toward the $91 the EIA forecast before its revision [27]. A direct hit on Gulf refining would widen the diesel premium faster than it lifts crude. An escalation that reaches Saudi oil sites or tankers would make the $105 average look low [15].
I think the repricing case is stronger for diesel than for crude. The crude forecast rests on an inventory draw that a short storm barely changes [34], while each refinery the storm closes adds to the diesel premium [6]. The view is wrong if that premium narrows after landfall while Middle East shut-ins keep falling.
What to watch
- Whether IEA members agree a release of diesel stocks large enough to narrow the $77 premium over Brent.
- Bids on the Energy Department's 40-million-barrel reserve tender, the last volume the March drawdown can supply.
- Progress of the Saudi-backed offensive against the Houthis, since this week's airport strikes came as it intensified.
