Strait of Hormuz traffic returns to normal by August 31?

Platform comparison

Market context

The Strait of Hormuz is currently closed to commercial shipping, with a brief reopening on 21 April 2026 reversed the following day after a vessel was struck. This abrupt suspension mirrors the volatility seen in 2022 when transit calls dropped sharply following a commercial ship hit, yet normal traffic has historically resumed within weeks once diplomatic pressure eases. The crowd-implied 20% probability reflects scepticism about a sustained return to the 60-ship threshold by August 31, given that the strait remains shut and throughput data is hourly from multiple sources[1]. Programmatically, a trader would monitor the IMF PortWatch AIS feed for a 7-day moving average breach, setting conditional orders to trigger only when the metric exceeds 60 for any date, rather than betting on a single-day spike[4].

Key catalysts include the US-Iran deal to reopen the waterway, which previously drove a sharp rise in commercial traffic as vessels sailed through under the agreement[5]. Traders must watch for announcements on war risk insurance premiums and stranded vessel counts, as these dependencies directly influence throughput data and global trade impact analysis[1]. Recent MarineTraffic data showed at least 50 vessels transiting in 24 hours, suggesting capacity exists if the closure lifts, yet traffic dropped sharply after a ship was hit, highlighting the fragility of current conditions[7][9]. A power-user would script a bot to scrape the Strait of Hormuz Live Tracker dashboard hourly, flagging any 7-day average breach above 60 to execute conditional orders before the market resolves[1].

Over 30,000 vessels pass annually, with daily oil transport exceeding 20 million barrels, meaning a return to normal traffic carries massive economic weight[8]. The settlement window ends 31 August 2026, leaving just 115 days for the strait to reopen and sustain the required volume. Historical precedents show that while closures are brief, the 60-ship threshold demands consistent throughput, not just a temporary surge. Traders should track peace talk status and crisis timeline updates, as these factors determine whether the strait remains closed or reopens for sustained transit[1]. The market resolves as soon as the metric is published, so real-time monitoring of the IMF PortWatch feed is essential for capturing the exact moment of resolution[4].
