Strait of Hormuz traffic returns to normal by October 31?

Platform comparison

Market context

Traffic through the Strait of Hormuz remains far below normal, so the contract needs a sharp and sustained rebound before the 60-transit threshold is met. Recent reporting put daily transits in the single digits, with Reuters noting just three commodity vessels on 17 July and nine on 20 August, while PortWatch-linked trackers still described the route as operating at roughly 4-7% of pre-crisis levels[3][11][2].

That makes the current 19% implied yes probability look cautious rather than aggressive, though still well above the near-zero pricing such a disrupted route might once have implied. The market sits in a classic lagged-data setup: PortWatch publishes a 7-day moving average, so even a brief improvement in daily flows would have to persist long enough to lift the rolling figure from the teens into the 60s, which is a big move from the latest reported range of about 3 to 18 transits a day[1][4][9]. Comparable escalations in July and August showed how quickly traffic can fall after renewed strikes or maritime risk warnings, and how quickly rerouting decisions by major carriers can keep volumes depressed[3][8].

For traders, the key catalysts are any de-escalation in US-Iran tensions, changes to naval or maritime security advisories, and evidence that large carriers are resuming regular Gulf schedules. Reuters has already linked the slump to renewed attacks and the reimposition of a US naval blockade on Iranian ports, while shipping trackers have noted continued rerouting and very limited tanker movement, which matters because the market resolves only on IMF PortWatch’s published shipping counts, not anecdotal port activity[3][12][6].
