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 transit counts near zero against a normal baseline of roughly 60 vessels per day. This blockade has suspended the flow of container, dry bulk, and tanker ships, creating extreme war-risk premiums and stranding multiple vessels. The closure follows a brief reopening on 21 April 2026 that lasted only until the next day, highlighting the fragility of any temporary access [1][4].

Historical data shows daily averages plummeting to six ships between March and May 2026, down from 100, yet a single reopening event saw 25 commercial vessels cross in one day, more than triple the recent average [4][5]. For a power-user evaluating conditional order tools, this market demands a programmatic approach: set automated alerts on the IMF PortWatch 7-day moving average to trigger buys only when the metric exceeds 32.57, the last recorded average, while monitoring for sustained spikes above 60 [7]. The current 21% implied probability reflects the difficulty of achieving seven consecutive days of normal traffic given the current blockade [1].

Traders must watch for official peace-talk announcements and scheduled diplomatic meetings that could force a reopening, as the market resolves only if the 7-day average hits 60 before August 31, 2026 [1]. Recent reports confirm the strait remains closed with commercial traffic suspended, meaning any catalyst must deliver immediate, sustained throughput rather than a fleeting surge [1]. The dependency on IMF PortWatch reporting excludes unreported ships, so traders should verify data sources against MarineTraffic to ensure the metric captures the full volume required for settlement [3][9].
