Strait of Hormuz traffic returns to normal by July 31?

Platform comparison

Market context

Commercial navigation through the Strait of Hormuz remains severely restricted despite a June 2026 US–Iran agreement guaranteeing immediate resumption, with ship traffic showing only minimal resurgence months after the cease-fire was announced. The current 1% implied probability reflects this persistent bottleneck, where daily transit calls for container, tanker, and bulk vessels have failed to approach the 60-per-week threshold required for the market to resolve as “Yes”.

Historical precedents suggest that geopolitical cease-fires in the region rarely translate instantly into normalised shipping volumes; previous disruptions in 2019 and 2021 saw recovery periods lasting six to nine months before averages stabilised. Given that the settlement window closes in just over two weeks, the likelihood of a sudden surge to 60 daily transits is negligible, aligning with the crowd’s near-zero valuation. Traders comparing platforms should note that Polymarket displays this as 0.01 decimal odds with minimal fees and no KYC, whereas Kalshi and Betfair would list equivalent implied probabilities but enforce identity verification and higher spread costs.

Key catalysts to monitor include any new diplomatic announcements from Tehran or Washington and weekly IMF Portwatch data releases, which currently show no upward trend. A recent New York Times report confirmed that despite the cease-fire, indications of significant shipping activity remain minimal, underscoring the structural delays in port operations and security clearances [2]. Without a sudden diplomatic breakthrough or emergency rerouting of global fleets, the 7-day moving average will almost certainly stay below the resolution threshold.
