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 calls near zero against a normal baseline of roughly 60 vessels per day. This abrupt suspension follows a brief reopening that failed to sustain momentum, leaving the waterway effectively blocked for container, tanker, and bulk carriers. The market’s 21% implied probability for traffic returning to normal by August 31 reflects the severe operational friction and the lack of a clear on-ramp for vessels to resume regular flows.

Historically, similar closures in the region have persisted for months, often driven by mine-clearance delays or geopolitical tensions that stall the seven-day moving average required for resolution. Past data shows that even after reopening, traffic frequently remains limited, with outbound movements dominating and daily averages hovering well below the 60-vessel threshold. This pattern suggests that the current low probability is not merely speculative but grounded in the recurring difficulty of restoring full transit capacity.

Traders should monitor announcements regarding mine-clearance operations and the scheduled reopening of the waterway, as these are the primary catalysts for any sustained traffic increase. Recent reports indicate that mine clearance may delay the restart of normal shipping, with the seven-day moving average needing to exceed 60 ships to signal a return to business as usual [3]. Additionally, watch for IMF PortWatch updates on daily transit calls, as the latest data from late June recorded only 27 daily calls and a 32.57 seven-day average, far below the required level [8]. The funding flows driving book depth on this market remain tied to these operational dependencies, with deposit and withdrawal rails like SEPA and USDC reflecting the cautious sentiment among participants.
