News of a potential new deal between the United States and Iran to reopen the Strait of Hormuz is sparking hope for a new ceasefire. Although nothing has been signed, all eyes are on this strategic choke point, which once again has driven a surge in oil and gas prices.
This maritime passage is a vital waterway through which roughly 20% of the world’s crude oil flows. As conflict tensions fluctuate, shipping disruptions have returned, sparking renewed trading volume in the Kalshi market tracking: "When will traffic at the Strait of Hormuz return to normal?"
Contracts that saw their prices spike ahead of June 17—the date of the short-lived preliminary ceasefire—have plummeted as hostilities resumed and subsequently entered a volatile, zigzagging trend amid expectations for a new deal. For forward-looking traders, analyzing the intersection of this market and the current geopolitical reality reveals where the true value lies.
Where is the Opportunity?
Kalshi puts normal Hormuz traffic by September 30 at 28%.
The strait is moving about 12% of its pre-crisis vessel count, and the market gives it 54 days to close the rest of that gap.
The contract resolves on IMF PortWatch, YES if the 7-day moving average of transit calls prints 60 or higher on any date through September 30.
That average sat near seven a day in the first week of August, with 52 ships transiting between July 27 and August 2, up from 28 the week before.
So, the question on the board is whether traffic multiplies by eight within two months. Yes trades at 28% and has $2.19 million of volume behind it.
It's worth knowing what the bar counts: PortWatch transit calls include container, dry bulk, roll-on/roll-off, general cargo, and tankers, so this is a shipping-volume question, not an oil-flow question.
The nearest-dated version of the same contract, normal traffic by August 15, is priced at three-quarters of 1%.
The price already moved on the diplomacy. Yes was 15.5% on July 31, then 29.5% by August 4 as the US, Iran, and Oman closed on an interim agreement. Volume on August 2 alone was $414K against $26K the day before, and posted liquidity roughly doubled to $353K.
And the price still cannot hold above 30%.
The reason is sitting inside the deal's own calendar. The draft sets up a temporary 60-day routing system: inbound ships through Iranian waters to the north, outbound through Omani waters to the south, no tolls or approvals. Clearing mines from the central channel is scheduled to begin within 30 days, and security firms have put the sweep itself at weeks once it starts.
Start that clock at the announcement, and the median lane opens in late September at the earliest. The deadline on this contract is September 30.
A two-lane workaround is also not 60 ships a day. War-risk premiums, crew willingness, and charterer appetite move slower than the headline, which is why the traffic count has been climbing in ones and twos rather than in bulk.
Iran's remaining conditions for a deal mostly sit outside the shipping issue entirely: ending the naval blockade of its ports, relief on the oil sanctions reimposed when the truce collapsed, and its frozen assets.
The rest of the ladder tells the same story. August 31 sits at 12.5%, September 30 at 28%, December 31 at 58%, and the market for traffic not returning to normal in 2026 at 42%. That leaves roughly 30 points of the reopening priced into Q4, after the mine sweep would finish.
Brent near $81 is back around pre-war levels, so the oil market has priced the crisis winding down while the transit count has not yet moved with it.
The Trade
No, at 72 cents is the best side, and the math is why: 54 days, an eightfold traffic increase, and a mine-clearing operation whose start date is scheduled inside the contract's own window. The invalidation is a fast median-lane clearance, which could instill confidence in global shippers that mines and other risks have calmed.
Not financial advice.
