Yesterday the deadline expired. Today both governments removed the thing that normally follows an expired deadline, which is an extension.
Brent climbed 89 cents, or 1%, to $91.76 by 0641 GMT, its highest since 30 July. WTI rose $1.05 to $85.55, its highest since 31 July. Both have now risen three sessions running. By mid-morning Eastern Brent had eased to around $91, having traded between $89.30 and $91.84.
Three straight up sessions is worth pausing on. For two weeks the pattern here was an escalation headline lifting the price at the open and being sold into by midday. That pattern broke on Monday. It is now clearly not the pattern at all.
Iran Threatens to Break the Blockade by Force
A senior Iranian official told Reuters on Monday that Tehran will shift to a "fully offensive" military posture, because talks on a permanent end to the war have stalled.
The language is specific about where. Iranian entities "must be prepared to escalate tensions in the Strait of Hormuz and wider region," the official said, "as Iran will be ready to make decisions and take action on difficult decisions." If diplomacy fails, Iran would mount a "timely and precise" military attack to break the American naval blockade.
There is a deadline attached, and this time it is Iran's. The official said Washington must meet the memorandum's provisions in full within a few weeks as a precondition for any further negotiation.
Read that against the calendar. The memorandum Iran is demanding compliance with is the one that expired yesterday, 60 days after it was signed on 18 June. Tehran is asking the United States to honour an agreement that no longer exists, as the price of talking about a new one.
Washington Removed the Other Exit
The United States ruled out extending the temporary ceasefire.
That closes the obvious off-ramp. An expired agreement can be rolled over while something better is negotiated, and that is the ordinary way these things are kept alive. Both governments have now declined to do it within a day of each other.
Neither has described what replaces it.
A Ship Was Hit Again Today
A projectile struck a vessel transiting out of the Strait of Hormuz on Tuesday. It is the latest in the run of attacks that has held crossings in single digits, and it follows the three vessels operated by Abu Dhabi National Oil Company that were hit last week.
In the Red Sea, the Houthis launched missiles at what they described as a Saudi military vessel and four escorting ships.
That second item matters more than it looks. Saudi Arabia's answer to Hormuz has been to route around it, through the Red Sea, which is why it assembled a 15-country maritime coalition covering Bab al-Mandeb. The Houthis are now firing on the escorts of that workaround.
Iran's President Says the Quiet Part
Speaking at the weekend, President Masoud Pezeshkian described the state of the Iranian economy in plain terms.
"Our income has also decreased," he said. "We used to sell oil, now we can't." He added that "our problems have worsened dramatically, while our income has declined," attributing it to lost oil revenue, damaged factories that can no longer be taxed, and imports arriving by longer and dearer routes.
This is the strongest public evidence yet that the pressure campaign is doing what it was designed to do. It is also why today's escalation is worth taking seriously rather than reading as bluster. A government whose president concedes it cannot sell its main export has a motive to settle. Iran is not settling. It is promising to attack the blockade instead.
A Number Going Around Today Is Three and a Half Months Old
While checking those economics, a search returned the figure that the American blockade has cost Iran $4.8 billion, with 31 tankers holding 53 million barrels stranded in the Gulf of Oman.
That reporting is from 1 May. The blockade began on 13 April, so the figure covers roughly its first two and a half weeks. It came back to us today with no date attached, in the same week a 2023 Aramco story and a February IEA report were served to us as current.
We are not repeating it as a current number, and neither should anyone else. The direction it points is almost certainly right, and it is now the third stale figure to reach us in seven days. This is the second item on our reference page on oil data traps: the date of a number is part of the number.
What Else Is Standing
Treasury Secretary Scott Bessent said on 14 August to watch for announcements "next week" of measures unlike any "in the history of economic isolation on a country." That week is this week. Nothing has been published yet.
Analysts are not treating the rally as a breakout. Tim Waterer of KCM said oil "has jumped to start the week as U.S.-Iran relations look increasingly shaky." Suvro Sarkar at DBS Bank expects crude to hold a range "between $80 and $100 a barrel in the near term" until the shape of a deal is known.
Saudi Aramco's September allocations to Asian refiners, which collapsed into case-by-case negotiation rather than a normal monthly round, remain the hardest read on what refiners actually expect.
What to Watch
Whether Iran attaches a date to its few weeks. An unnamed official's threat with a vague horizon is the cheapest form of pressure available. A named official with a date is a different instrument.
Whether Bessent's measures arrive this week as promised, and whether they reach past Iranian entities to the banks, insurers and shippers that move the oil. Anything short of that is another round of sanctions on a country already under a naval blockade.
Whether the Houthis keep firing on the Red Sea escorts. Hormuz is shut and the workaround is now being shot at, which is the condition that would take the price out of the $80 to $100 range the analysts are quoting.
