Washington denies negotiating as Tehran and Muscat carve up the Strait’s revenues

The commodity desk at TradingEconomics, in an entry dated 28 August, reported that “Iran and Oman agreed on a revenue-sharing framework for the strait, although Tehran emphasized that this does not imply an immediate reopening,” following its 27 August note that the two states had “reached an agreement over each country’s share of the Strait of Hormuz’s waters and related revenues.” That is a market-data aggregator relaying an underlying report The Files has not matched to a wire, and it should be read as such. The price moved regardless: Brent fell below $87 on Thursday, a fourth consecutive session of decline, and WTI slipped to around $83 on Friday. The same desk attributed part of the week’s move to non-Iranian factors — Vladimir Putin saying the Ukraine talks had produced no results, and Ukrainian strikes on Russian refineries and ports.

While the framework was being reported, CNN’s rolling Iran page, updated 8:13 AM EDT on Friday 28 August, ran under the headline “US says not talking to Iran as Hormuz diplomacy intensifies,” carrying a White House video segment captioned “White House: No negotiations happening between U.S. and Iran.” The same page recorded that Qatar’s prime minister visited Tehran on Thursday 27 August and met Foreign Minister Abbas Araghchi. President Trump has separately described the position differently: in a phone call reported by ABC News he said “we are only semi-negotiating with them” and “we are low-keying it.” Al Jazeera’s 26 August liveblog was headed “Trump says US ‘not in a hurry' over talks with Tehran.” France 24, the same day, put the state of play flatly: Iran and Oman “have yet to agree on the conditions for the waterway’s reopening as the Middle East war nears the six-month mark.”

The unresolved question is not fees but jurisdiction. The Congressional Research Service, in product R45281, records that Iran established a “Persian Gulf Strait Authority” in May 2026 and claimed that “no vessel is permitted to pass through the Strait of Hormuz without a valid passage permit issued by the PGSA,” and quotes Parliament Speaker Mohammad Baqer Ghalibaf on 23 June saying “management of the Strait will never return to the way it was before the war.” CRS states that “Iranian claims run[] counter to the geographic reality that the Strait comprises both Iranian and Omani territori[al waters].” Al Jazeera reported on 6 August that US officials “would not accept any arrangement on the waterway that would leave Iran in control,” and that Tehran insists it is negotiating only with Oman. Kpler data reported by Al Jazeera counted 236 transits of all cargo types between 1 and 19 August, against a pre-war baseline the outlet gave as roughly 130 ships a day.

Assessment: Every “deal is close” report since Bloomberg’s 5 August story has produced a communiqué and no ships. The tracker straits.live, writing to 28 August, identifies why: Iranian state media claims a temporary corridor has been agreed, while a senior Iranian lawmaker told Mehr News — also state media — that the blockade must be lifted before any agreement is finalised. Read that as either factional split or deliberate ambiguity; either way it is the reason a revenue split can be announced without a reopening. Treat the framework itself as unconfirmed until a wire carries it. And note what the negotiation is actually over: not tariffs, but whether the PGSA survives as the body that issues permits.
