ReversalIran's price for reopening Hormuz has stopped falling: the security council now bills seven conditions, so the narrowing ask was a floor, not a trend heading for a deal.

Iran's stated price for reopening the Strait of Hormuz went up on Wednesday. At 16:47 UTC the secretary of the Supreme National Security Council, Mohsen Rezaei, said Iran will not negotiate with Washington or reopen the waterway until the United States meets seven conditions. Every earlier count of that bill in this record was smaller than the one before it. The last one was one.

Two items here put a number on the bill, and both came from the same council. On 8 August its then-secretary set out five conditions: a permanent end to American operations against Iran-aligned forces in Lebanon, Palestine, Yemen and Iraq; the naval blockade lifted and US forces withdrawn from around Iran; compensation for two wars; sanctions relief with the frozen assets released; and no threats or insults to Iran's values. He was replaced within days. Forty-six days later the same office, under his successor, says seven. Nothing on the five has been paid.

The low was fifteen days ago and it has not survived. On 8 September the foreign minister said normalising the strait required Washington to return to the Islamabad memorandum - one document, already signed - and this site read it as the ask collapsing to a single line. Tehran's wire then went just under twelve days without naming a price for reopening at all; the only deal news in the gap was Iran telling all three state agencies that the Muscat agreement does not mean reopening the strait. When terms came back on 20 September the speaker of parliament had them relayed to Washington without saying what they were. On Wednesday they were seven.

The count lives in the office that works the valve. The same council announced the temporary Iran-Oman corridor on 28 August and declared the strait completely closed nine days later. Parliament has been working the other lever: on 6 August it was weighing tolls of up to 7 percent of cargo value, and on Tuesday its national security commission approved penalties for vessels breaking Hormuz transit rules, which IRNA describes as legislative steps to consolidate Iranian control of the chokepoint. A fine schedule is not a blockade. It is what a state writes when it expects ships to keep coming and means to charge them.

The tape cannot referee any of this yet: the official closes here end on 15 September at 130.80, eight days behind the wire. On that series Brent is 49 percent above its last close before the five-condition list and 23 percent above the close on the day the ask was one document, so the stretch in which Iran's bill grew is also the stretch in which the thing it is billing for got dearer. Stop reading the narrowing ask as a path to a deal - it was a floor, and it has lifted. What is worth watching next is not Rezaei's number but the Majlis order paper, because a legislated toll prices transit through a closed strait rather than reopening it.
