Brent holds above $100 on two supply threats of unequal size

Set against September's Middle East shut-ins, the storm's curtailment is about a twenty-sixth of the size ^[29]. At 9.2% of Gulf offshore production, it implies an offshore base of roughly 2 million barrels a day ^[24]. As of Tuesday morning, no personnel had been taken off platforms or rigs ^[8]. 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" ^[3]. 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 ^[14], and Ukraine struck two Russian oil facilities on Wednesday ^[15]. Add the diesel premium to Brent's price at the same hour and European diesel was near $178.80 a barrel ^[25].

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" ^[20].

Before its revision the EIA had the quarter averaging $91 ^[31]. 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 ^[19][32]. The Energy Department's offer of up to 40 million reserve barrels equals about 62% of that draw ^[13][33]. 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 ^[26]. Saudi Energy Minister Prince Abdulaziz bin Salman said the East-West pipeline had reached 5.8 million barrels a day ^[22]. 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 ^[23]. "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 ^[21]. PVM's Tamas Varga said investors lack conviction that the recent rise in Middle East supply and exports is sustainable ^[11].

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 ^[7]. 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 ^[12].

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 ^[31]. 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 ^[18].

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 ^[10]. The view is wrong if that premium narrows after landfall while Middle East shut-ins keep falling.
