Strait of Hormuz traffic returns to normal by August 31?

Platform comparison

Market context

Outbound commercial traffic through the Strait of Hormuz remains effectively halted, with zero verified outbound movements recorded over the past 72 hours as of late June 2026[1]. This severe bottleneck stems from the ongoing conflict with Iran, which has closed a route previously handling roughly 20% of global oil supply[3]. The current 17% crowd-implied probability reflects the stark reality that the 7-day moving average of transit calls is currently near zero, far below the 60-call threshold required for a “Yes” resolution, making a return to normal traffic by August 31 a statistically improbable event unless a major geopolitical shift occurs.

Historically, similar chokepoint closures driven by regional conflict, such as the Red Sea disruptions, saw traffic recover only after explicit ceasefire terms or naval de-escalation were confirmed. In this case, President Trump has stipulated the strait’s reopening as a prerequisite for any ceasefire with Tehran, yet peace negotiations show minimal progress and a US naval blockade against Iran has been declared[3]. Programmatic traders should monitor IMF Portwatch’s daily API for the 7-day moving average, setting conditional orders to trigger only if the metric breaches 55, anticipating the final push to 60, while watching for sudden announcements regarding mine removal or toll suspensions.

Key catalysts include any official statement from the US or Iranian governments regarding the blockade or tolls, as well as verified reports of mine-laying activities that could further delay reopening[3]. Traders building bots should cross-reference IMF Portwatch data with live AIS trackers like MarineTraffic to validate transit calls, ensuring the algorithm accounts for ships altering GPS tracking during transit[3]. Without a rapid diplomatic breakthrough or a unilateral lifting of the blockade, the data trajectory suggests the market will resolve to “No” as the settlement window closes.
