Brent Recovers to $88.35 After Dipping Below $86.25, as Trump Claims Strait Is Open and Diesel Stocks Hit Record Seasonal Low

Thursday, August 27, 2026 | 6:00 AM ET

Brent (Oct) $88.35 | WTI (Oct) $82.41 Brent +0.51, WTI +0.18, after touching session lows of $86.22 and $80.65 respectively before rallying more than a dollar in the past 90 minutes. The overnight tone was weaker, but the reversal is tracking a mix of headlines: Iran's Revolutionary Guards claim a revenue-sharing deal with Oman on the strait has been reached, Trump insists the strait is already open and mine-free, and Qatar's prime minister heads to Tehran today to relaunch mediation. Another tanker was struck by a projectile in Hormuz Tuesday, per UKMTO, though it reached Fujairah safely. Martin Kelly of EOS Risk Group is now reporting that a Kuwaiti oil tanker has been struck, likely by Iranian fires, in the Strait of Hormuz. No corresponding report from the United Kingdom Maritime Trade Operations (UKMTO) Centre at the time of writing.

Bottom Line

The rally in the last hour and a half looks like it's being driven by the IRGC's claim, which goes further than anything the two governments have said officially. Spokesman Hossein Mohebbi said Iran and Oman have agreed on each country's share of the strait's waters and its revenues, and specifically blamed the U.S. for obstructing progress. That's a materially stronger claim than Tuesday's joint foreign ministry statement, which only described an "interim framework" being discussed and didn't mention fees or revenue-sharing at all. Neither foreign ministry has confirmed the IRGC's version. Phillip Nova's Priyanka Sachdeva's framing is worth keeping in view here: the core dispute remains Iran's nuclear program, which isn't getting resolved on any of these near-term timelines, and Iran understands exactly how much leverage its geography gives it, so prolonged uncertainty stays the base case even amid genuine-sounding progress on the shipping mechanics specifically.

Trump's claim that "the mines are gone," that the strait is open, and that some 10 million barrels transited yesterday sits directly at odds with both Iran's position and the IMO's. Iran says only its own officials know where the explosives actually are, and the IMO said last week it has no confirmation mines have been removed at all. That's now three parties, the U.S., Iran, and the IMO, giving three different answers about the physical state of the same waterway, which is about as clear a sign as you'll get that nobody outside Tehran and Washington actually knows what's true here. KCM's Tim Waterer's framing fits the moment: if Hormuz does reopen more fully, a further leg lower in crude is plausible, but the market won't price a full return to pre-conflict levels overnight, and the bigger risk right now is that today's optimism proves premature and talks stall again, which would snap the risk premium right back.

Actual traffic data continues to undercut the more bullish claims. Five vessels transited Tuesday, matching Monday's tally but still well below the 10-day average of 15, and Windward's more granular count shows just six tanker crossings as of Wednesday, three in and three out. About 65% of Hormuz-origin crude is bound for China specifically, per Windward, which is a useful number for sizing exactly whose supply chain is most exposed to however this resolves. Wednesday's uptick in overall traffic that Reuters flagged is real but modest, and it's happening against a backdrop of continued attacks, Tuesday's UKMTO-reported strike on a Liberian-flagged Aframax carrying 704,000 barrels of jet fuel followed Monday's separate attack off Oman, both in the same corridor Iran and Oman are now negotiating over.

The diesel inventory story deserves attention on its own, separate from the Hormuz theater. U.S. distillate stocks fell to 103.4 million barrels for the week ended August 21, the lowest for this time of year in EIA records going back to the early 1980s. That's landing right before global diesel demand typically peaks in October, when Northern Hemisphere heating season and harvests overlap with Southern Hemisphere planting. UBS's Giovanni Staunovo flagged the mechanism that's kept this from being worse so far: SPR releases have been compensating for the disruption, but those sales are ending soon, which means inventory draws accelerate from here without some improvement in either Hormuz refined product flows or Russian diesel availability. Russia's own export ban, still under consideration for a further one-month extension, is compounding the same shortage. Retail diesel in the U.S. is already above $5.60 a gallon, within 20 cents of the 2022 record, even as crude itself trades well below its own recent highs, a genuine divergence between the crude and product markets worth keeping in mind when reading today's headline price alone.
