Iran has put a clock on reopening Hormuz. Every earlier clock in this record was an expiry date

Tehran has put a number of days on the strait four times in 278 recorded statements, and every one was a deadline for withdrawing something. Saturday's seven-day plan is the first lead time.

Iran's foreign minister published a schedule for reopening the Strait of Hormuz on Saturday morning: seven days, once Washington accepts Tehran's conditions. A schedule is a new kind of object in this record. For seven months Iran has priced the strait exclusively in demands — five conditions in August, seven last Wednesday — and has never once said how long the reopening itself would take. A number of days has now been named, and nothing about the price has moved.

Tehran has named a number of days before, and every previous instance ran the other way. Across the 278 Iranian statements this site reads, exactly four attach a duration to the strait. On 7 April Araghchi confirmed safe passage "for two weeks" under the ceasefire. On 17 June Pezeshkian signed the Islamabad Memorandum granting toll-free passage "for 60 days only"; the next day the Majlis speaker said Iran would charge for services once that window closed, and the day after that the ports authority's insurance letter reserved the right to introduce fees on the same schedule. All four measured how long something already granted would survive. Saturday's seven days measures how long something not yet granted would take to arrive. It is the same grammar pointed in the opposite direction, and it is the first time this file contains a lead time rather than an expiry.

The natural reading of a timetable is that a concession is coming, and the rest of the weekend's wire refuses to support it. Araghchi spent Sunday across all three state agencies holding the price exactly where it was: Tehran has clearly presented its conditions and will not back down from them, and reopening depends on US fulfillment of them. Three days before the plan appeared, the security council's secretary put the bill at seven conditions — the only time in this record Iran's asking price has gone up rather than down. So what changed on Saturday is the shape of the offer and not its cost. Iran has published a delivery time for goods it is still declining to discount.

No price has had a chance to answer, and on this site's own numbers none should be expected to. The plan went out at 06:26Z on a Saturday, so the first Brent close that could price it is Monday 28 September; the three closes before it, 23 to 25 September, are not in the official series yet, which still ends at 114.89 on 22 September. Iranian words are in any case a null in this data: days carrying them move Brent 0.88 times as much as quiet days, a difference with a permutation p of 0.67, which is to say no difference. A move on Monday would be the exception rather than the pattern, and the absence of one would tell a reader nothing.

The condition count has been the number to watch in this record for months, and it has just stopped being informative — it rose last week, and Tehran says it will not come back down. The clock replaces it. Seven days is the first claim Iran has made about the strait that can be checked against a calendar instead of against a list, and it is checkable in one direction only: until somebody starts it, a seven-day plan to reopen Hormuz is a timetable for an event no party has agreed to trigger. The question worth tracking is no longer what Iran is asking for. It is whether the week ever begins.
