Market impact:The reported rejection adds a fresh complication to the fragile arrangement governing traffic through the Strait of Hormuz, a waterway carrying roughly a fifth of global oil and LNG trade. If accurate, it suggests the post-conflict framework for administering the strait, agreed under the US-Iran memorandum, remains unresolved even as the safe-passage window created by that deal ticks down. I'm wary of leaning too hard on this one given the sourcing sits on a single unnamed official, but if it holds up, it meaningfully complicates the kind of full-reopening scenario that underpins bearish medium-term forecasts such as Citi's, and keeps a risk premium embedded in prices for longer than that forecast currently assumes. The claim originates from a single unnamed source and has since been picked up by other outlets including TASS, but has not been independently corroborated by Reuters, AP, or an on-record Omani statement, so its market impact should be treated with care.-A single-sourced report, now repeated by TASS, says Oman has quietly walked back an Iran fee plan for Hormuz, muddying an already fragile waterway arrangement.Summary:The New York Post reports, citing an unnamed high-ranking regional official, that Oman has rejected Iran's proposal for the two nations to jointly charge fees on vessels transiting the Strait of Hormuz.The report contradicts a claim made last week by Iran's Islamic Revolutionary Guard Corps that a fee-sharing deal had already been reached.According to the report, fee terms had not even been finalised on Iran's side, suggesting the IRGC's statement got ahead of the actual state of talks.The report has since been repeated by other outlets, including Russian state-run agency TASS, without additional independent sourcing being added.Oman's foreign minister has previously distinguished between mandatory tolls, which Oman opposes, and a voluntary-contribution model similar to arrangements used in the Strait of Malacca.The fee question sits within the broader US-Iran memorandum, under which safe passage through Hormuz was guaranteed for 60 days while Iran, Oman and other Gulf states worked out longer-term administration of the waterway.US President Trump has twice threatened to bomb Oman if it agreed to what he characterised as de facto tolling of the strait.Oman has quietly rejected an Iranian proposal for the two countries to jointly charge fees on commercial vessels transiting the Strait of Hormuz, according to a New York Post report citing an unnamed high-ranking regional official. The report states that Muscat declined to accept fees, even on a voluntary basis for environmental and security services, contradicting a claim made last week by Iran's Islamic Revolutionary Guard Corps that a fee-sharing arrangement had already been agreed.According to the same report, the terms of any proposed revenue-sharing deal had not been finalised even on Iran's side, with a separate source indicating the IRGC's public statement got ahead of where the negotiations actually stood. The fee dispute sits inside a broader and still-unsettled framework for managing the strait. Under a memorandum of understanding signed between the United States and Iran last month, ships were guaranteed safe passage through Hormuz for sixty days, with the longer-term administration of the waterway left to be worked out between Iran, Oman and other Gulf states.Oman's position on fees has shifted in tone rather than substance in recent months. Its foreign minister, Sayyid Badr al-Busaidi, has previously drawn a distinction between mandatory tolls, which Muscat opposes, and a voluntary-contribution model resembling the one used in the Strait of Malacca, where Indonesia, Malaysia and Singapore invite shipping companies to fund navigation, environmental and search-and-rescue services without imposing a compulsory charge. That earlier openness to a voluntary model makes the reported rejection notable, since it suggests Oman has retreated even from the softer version of a fee arrangement.Politically, Oman has reason to distance itself publicly from any Iran-linked toll scheme: President Donald Trump has twice threatened to bomb Oman if it agreed to what he described as de facto tolling of the strait, and Washington has separately signalled that any Iranian toll on Hormuz would be treated as a red line.The report has since circulated further, with Russian state-run agency TASS repeating the claim without adding independent sourcing of its own. Given the reporting chain runs back to a single unnamed official, and that TASS's pickup does not constitute separate corroboration, the story should be treated as reported rather than confirmed. Independent confirmation from Reuters, AP, or an on-record Omani government statement has not yet emerged.Oman sits on the southern side of the contested Strait of Hormuz (I think everyone in the entire world knows this by now ;-) ) This article was written by Eamonn Sheridan at investinglive.com.
