Traders now expect a US-Iran ceasefire within weeks. They do not expect the blockade or Hormuz to follow.
Trump calls the war "effectively over" and says new strikes are "highly unlikely". The distance between a pause in fighting and a working Gulf is where the risk sits.

Key points
- Traders see a ceasefire by 22 November as more likely than not
- A deal that reopens Hormuz by year end is a one-in-three chance
- The blockade is more likely to outlast November than to end
"Iran, militarily, is effectively over. We're just keeping it the status quo." Donald Trump said that at the White House on Monday, after meeting Qatar's prime minister, and added that US forces remained "locked and loaded" if circumstances changed. A day earlier he had told CNN that renewed attacks were "highly unlikely" if Tehran signs "a very strong agreement".
The market reading of that is specific. Traders put the chance of an effective US-Iran ceasefire, a pause of at least two weeks, beginning by 22 November at 60%, up 11 points in a day (as of 10 November). They see the status quo hardening into something formal. They do not see it becoming peace.
A pause is priced. A settlement is not.
The chance of a ceasefire starting by 15 November is 46.5%. By 22 November it is 60%, by 30 November 65% and by the end of the year 80%. The central expectation therefore sits in the middle of this month, and most of the remaining doubt is about whether it slips into December rather than whether it comes.
Each of these has drawn only about $100,000 of trading, so the shape matters more than any single figure. The shape is consistent: a pause is likely, and soon.
Everything that would turn a pause into a settlement is priced much lower. The chance that the US announces an end to its naval blockade by 30 November is 17.5%, by 31 December 37%, and by 31 March 69%. A US-Iran agreement covering the Strait of Hormuz has a 15% chance by 30 November and 33.5% by year end. A final nuclear deal by 31 December is a 12.5% chance.
A pause at eight in ten by year end sits beside a one-in-three chance of a Hormuz agreement in the same period. In between lies a stretch in which guns are quiet but ports, tankers and sanctions are not.
Why the gap is wide
The Iranian position explains most of it. Tehran sent a proposal through Qatari mediators on Thursday 5 November, but says it will discuss it only after Washington meets seven demands. They include lifting sanctions imposed after the collapse of June's Islamabad memorandum, reinstating oil waivers, releasing frozen funds, reducing the US military presence, and formal recognition of an Iran-Oman shipping route through Hormuz with all other routes closed.
Washington's stance runs the other way. Trump has said the blockade stays, and the White House says the US has "control of the Strait of Hormuz". Secretary of State Marco Rubio said at the weekend that "I wouldn't say we're at the verge of a breakthrough." Qatar's prime minister, Sheikh Mohammed bin Abdulrahman Al Thani, said the US has shown willingness to "take steps towards finding a solution", a long way from a deal.
A ceasefire asks each side to stop. A Hormuz agreement and the end of the blockade ask each to give up leverage. That is why one is priced as likely and the other is not.
The fighting has not stopped
The calm is also less complete than the rhetoric. The US struck Iranian air defences at least twice in the week to 9 November, and on Saturday fired on a commercial ship it said was trying to breach the blockade. Axios reported that US Central Command is preparing to resume major operations and awaiting orders. Trump has said three carriers are in the region and that 38 bridges are identified as targets.
On Monday the Wall Street Journal reported that US aircraft were moved out of RAF Mildenhall in England after an Iran-linked threat, the second British base to be cleared in recent weeks, after B-1 bombers left RAF Fairford following a security incident in September. Britain's defence ministry declined to comment on other nations' activity. The nature of the threat is still being assessed by US officials.
France added a new strand on Monday. Paris attributed last month's cyberattack, which pushed refrigerator temperatures to 50C in about 700 supermarkets, to a unit linked to Iran's Revolutionary Guard. It summoned Iran's ambassador and said it would seek European sanctions. A war that has paused in the Gulf is still being fought elsewhere.
Traders think an American ground war is receding. The chance of a US invasion of Iran before 2027 is 9.5%, down 8 points in a week.
Where the market could be wrong
The strongest case against a quick ceasefire is that Tehran has not accepted Washington's account of progress, and that Trump reportedly told Qatar's prime minister he could reverse course if Tehran does not engage seriously. Another round of strikes would push the near-dated contracts down fast.
The case against the gap is just as plain. A ceasefire could carry its own momentum: with oil down and pressure on Washington to find an exit after the Democratic midterm sweep, the White House may trade the blockade for a Hormuz arrangement sooner than the 37% year-end price implies. Markets are split on timing, and not confident either way.
What it means for markets, business and politics
Markets Oil has priced the pause, not the peace. Brent settled at $92.57 on Monday, down 5.9%, its lowest since August. If a ceasefire arrives but the blockade and Hormuz restrictions remain, the supply that matters is still shut, which limits how far prices can fall.
Stocks and sectors Oil producers such as Exxon Mobil and Occidental carry the most risk from a faster-than-expected settlement; airlines such as Delta and United gain most from it. Defence contractors such as Lockheed Martin are exposed to the opposite outcome, a return to major operations.
XOMOXYDALUALLMTBusiness Shippers and insurers should plan for a long period of partial normality. A ceasefire without a Hormuz agreement leaves war-risk premiums, rerouting and Saudi Arabia's East-West pipeline, itself hit in a recent attack, at the centre of supply planning.
Politics and policy The White House is under pressure to show an exit, but ending the blockade is its main bargaining tool. Expect it to hold that card for as long as Tehran's seven demands stand.
Geopolitics Cyber and basing incidents in Europe show the conflict can widen even as the Gulf quietens.
What to watch
The next test is whether the ceasefire chances for 15 and 22 November are confirmed or fade, and whether Iran answers Washington's examination of its proposal. If the blockade price for 30 November climbs above 25%, the market will be saying that the gap is closing faster than expected.
A silent Gulf is not an open one, and that distance is where the risk sits.
