Strait of Hormuz traffic returns to normal by October 31?
The market is pricing a very low chance that Strait of Hormuz transit activity gets back to a 7-day average of 60 or more by October 31. I agree with the broad bearish view on the Yes outcome, but I think the market may be somewhat overstating how unlikely a temporary rebound is, so my estimate is modestly above the current price.
Analysis
The key issue is not whether traffic improves at all, but whether the 7-day moving average of reported arrivals reaches the relatively high threshold of 60 on IMF Portwatch before the deadline. That is a demanding bar because it requires sustained, not just brief, normalization across a full week of data. Given the short remaining window and the lack of a visible catalyst in the supplied context, the path to Yes depends on a clear and rapid return of commercial confidence, insurance availability, routing stability, and uninterrupted reporting in the underlying data series.
The current market price implies only a small chance of this happening, and that pricing is directionally sensible if conditions in and around the Strait remain unsettled. For the average to move above 60, the market needs enough shipping activity to offset any lingering diversion of vessels, operational caution by carriers, or episodic disruptions that depress the daily count. Even if traffic begins to recover, the moving-average structure makes it harder to qualify quickly because the series must stay elevated long enough for older low days to roll out of the window.
Arguments for Yes are mostly about the possibility of a fast normalization once the market perceives reduced risk. Shipping patterns can rebound faster than many expect if there is a de-escalation in geopolitical tension, if carriers resume standard routing, or if prior disruptions prove to have been temporary. There is also some chance that reported transit calls rise sharply as backlogged or delayed voyages re-enter the corridor, which could push the 7-day average over the threshold sooner than a simple day-by-day reading would suggest.
Arguments against Yes are stronger because the event requires a specific quantitative recovery by a fixed date, and the threshold is set at a level that likely reflects near-normal operating conditions. Any continued security concerns, military tension, rerouting, or even just cautious behavior by shipping firms could keep the average below 60. With the market already heavily skewed toward No, the base case is that traffic remains below the qualifying level long enough that the 7-day average never fully recovers within the deadline.
Arguments
For
- Arguments for Yes: If regional risk perceptions improve quickly, shipping traffic can rebound faster than expected.
- Arguments for Yes: The moving average could cross 60 if a short burst of higher activity follows a period of suppressed transit.
Against
- Arguments against Yes: The threshold requires a sustained week of strong traffic, not just a one-day improvement.
- Arguments against Yes: With little time left, any gradual recovery is unlikely to fully clear the bar before October 31.
Key drivers
- The 7-day average must reach at least 60, which requires sustained recovery rather than a brief spike.
- Shipping behavior in the Strait can normalize quickly if perceived security risk drops materially.
- The remaining time until October 31 is limited, reducing the chance of a full weekly rebound.
- Any continued rerouting or caution by carriers would keep the average below the threshold.
Risk factors
- A sudden geopolitical de-escalation could trigger a fast rebound in transit calls.
- A backlog of delayed voyages could temporarily lift the moving average above 60.
- Data revisions or reporting quirks could move the published 7-day average in either direction.
- An unanticipated surge in tanker traffic could pull the average over the line even without full normalization.
Scenarios
Best case
Security concerns ease sharply, carriers resume normal routing, and reported arrivals rise enough for the 7-day moving average to hit 60 or more before the deadline.
Most likely
Traffic improves somewhat but remains below the qualifying level for most or all of the remaining window, leaving the market to resolve No.
Worst case
Traffic stays depressed or erratic, the weekly average never approaches 60, and the market resolves No without any close call.

The exclusion of Navier-Stokes from resolution is the key reason the zero-solved outcome still looks likelier than not.
