Thirteen Days Before Washington’s Oil Waiver Lapses, the Only Hormuz Figure on the Table Is a Toll

The commercial architecture of the proposed Iran–Oman arrangement became legible on Friday for the first time. Fortune reported that Iran is demanding between five and seven percent of the value of cargoes transiting the Strait of Hormuz, and that Oman has floated roughly three percent; Iranian officials have said publicly that Tehran would control outbound traffic and bar US and Israeli vessels. Bloomberg, reporting from Tehran that lawmakers spent the day debating the draft’s wording, filed under a slug noting Iran “mulls US ban” — a third-party corroboration of the same clause, as is a line on TradingEconomics' commodity page. None of this is a signed text. What it is, is a price. Three weeks ago, after Trump reinstated the naval blockade and announced a twenty percent fee on Hormuz cargo, Foreign Minister Abbas Araghchi told ABC News: “POTUS is absolutely right. Whoever provides secure and safe passage of commercial vessels through the Strait of Hormuz should be compensated for this service.” The principle was conceded in July by both parties. August is the haggle.

The calendar behind the haggle belongs to Washington. The US Treasury waived existing sanctions on the production, delivery and sale of Iranian-origin crude, petrochemicals and petroleum products through 21 August 2026 — confirmed by a Treasury statement and reported by CBS News in June. That is thirteen days out. On Friday, Treasury’s OFAC also issued press release SB0598, designating two major digital asset exchanges it says the Iranian government relies on to launder billions of dollars and to support the IRGC. Financial escalation and a deal described as close arrived on the same day, from the same government. The mediators supply the third caveat: Qatar’s foreign ministry said on 4 August that drafts are being circulated and efforts are “in very progressive stages” while stressing there are no direct talks between the parties. Every “deal is close” line this week has run through Muscat or Doha. The same discipline applies to the nuclear file: Vice-President JD Vance announced on 23 June that Iran had agreed to readmit IAEA inspectors. There is no public evidence in the record that inspectors returned.

The Mecca signing on Friday tells you what regional states think the outcome will be. Saudi Arabia, Turkey and Pakistan signed a mutual defence agreement with Mohammed bin Salman, Recep Tayyip Erdogan and Shehbaz Sharif present; Iran International reports the document never once names a threat, and Araghchi welcomed it on X: “When Muslims stand together, we can face every challenge by malicious outsiders head-on.” A defence pact signed during a US–Iran war that declines to name Iran, and which Tehran’s foreign minister publicly praises, is not a containment instrument. It is an insurance policy against the aftermath. Shipping is making the same calculation in its own currency. Lloyd’s List Intelligence’s brief for 27 July–2 August records non-Iranian gas carrier transits resuming after a two-week pause and containership transits after a one-week pause — the classes that leave first and return last — while noting the week “ended on a violent note.” Windward’s 6 August daily reported two commonly-managed tankers and a Liberia-flagged tug crossing the southern corridor with AIS off for roughly twelve hours.

Assessment: Two clocks are running and only one is public. The 21 August waiver expiry is a date Washington set for itself, which means it can be extended quietly and probably will be; the value of the toll dispute is that it is the first item in this negotiation with an arithmetic answer, and arithmetic can be split. Watch for the number, not the language. Distrust three things. First, the Fortune analytical frame that the emerging deal concedes Iranian control of the strait — the quotes carrying that thesis are unattributed in the copy we can see, and the five-to-seven-percent spread is the only hard element. Second, any account of the Mecca pact that reads it as anti-Iranian: Tehran’s own foreign minister endorsed it. Third, the return of gas carriers and boxships to Hormuz as evidence of confidence. Vessels transiting with their transponders switched off are not expressing confidence. They are pricing risk privately, which is what shipowners do when no state has published a text.
