Morning Highlights: Trump Denies Offering Iran Sanctions Relief; Brent Slips to $104.91 as US Weighs Red-Diesel Tax Relief Over Export Ban

Tuesday, September 29, 2026

Brent (November) $104.91 | WTI (November) $92.27

Brent slipped 37 cents (-0.35%) to $104.91 and WTI eased 33 cents (-0.36%) to $92.27 by 6:15 ET, fading from an overnight rally that had taken Brent to $106.77 late Monday. Trump publicly denied offering Tehran any sanctions relief and Reuters reported the White House is leaning toward broader red-dyed diesel sales as an alternative to an export ban.

Bottom Line

Overnight the diplomatic track took a public hit. Trump wrote on Truth Social Monday that reports he had offered Iran sanctions relief and access to frozen funds are untrue: "I offered them NOTHING." The denial was aimed at Axios and CNN, both of which cited unidentified US officials describing a willingness to trade economic relief for "concrete progress" on the nuclear file. That directly undercuts the de-escalation signal from Monday afternoon's CNN report, the one that helped crude round-trip the morning's rally. At the same time the private channel is still moving. US and Iranian officials spoke separately with mediators Monday, and further talks are expected to center on an amended version of the seven-day proposal Iran tabled at UNGA. Araghchi stayed in New York awaiting the definitive US reply, saying mediators had not officially relayed a rejection, and Iran's president Pezeshkian told CBS's Face the Nation that Tehran is ready for talks but will not accept "bullying or coercion." The sequencing gap is unchanged: Washington wants concrete nuclear steps first, Tehran wants the blockade lifted, funds unfrozen and oil sanctions eased first. Treat any single headline as one data point; a US official told Al Arabiya on Monday the chances of an agreement are "extremely slim."

On the screen, the rally faded into the morning. Brent printed $107.87 and was back at $104.91 by 6:07 AM ET, down 37 cents on the day; WTI sat at $92.27, down 33 cents. The physical picture carries the same tension as yesterday: Kpler's preliminary data put September Middle East exports at 12.8 million bpd, the highest since February, yet KCM Trade's Tim Waterer notes much of that volume still moves through workarounds like ship-to-ship transfers, less efficient and more costly than normal operations, which is why the risk premium is sticking. Waterer also argues the perennial hope of a deal is what keeps Brent from pushing sustainably above $110, while UOB's morning note flags reported Iranian pessimism about a deal before the Hormuz situation escalates further and calls the US-Iran standoff the dominant risk for energy prices and inflation expectations. The front of the curve agrees the market is not pricing relief yet: the Brent Nov/Dec spread held at $7.58 at 6:04 AM ET, roughly in line with yesterday's $7.68.

Diesel is where Washington's thinking showed its hand. Reuters reports the administration is considering regulatory relief that would allow broader sales of red-dyed diesel, letting some buyers avoid the federal fuel tax, and that this has emerged as the leading alternative to an export ban. That matters because it points to domestic price relief without restricting supply, which would deflate the European tightness premium the ban threat has been feeding and remove the refiner run-cut risk that has been pressing on WTI. It is still a proposal described by people familiar with the discussions, not policy, and it sits alongside the other options already on the table: voluntary refiner export cuts, the 90-day ban plan Politico reported last week, and Energy Secretary Wright's "restrictions, not a ban" line. With retail diesel near $6.53 a gallon, the White House is clearly shopping for the option with the least blowback.
