Strait of Hormuz traffic returns to normal by July 7?

Platform comparison

Market context

The Strait of Hormuz remains effectively closed, with commercial shipping suspended after a brief reopening in April 2026 that collapsed within a day. Tensions are at their peak following US strikes on Iranian military sites and Tehran’s retaliatory targeting of a US base, leaving transit calls near zero against a normal baseline of roughly 60 ships daily[1][2]. This ongoing crisis has already cost the global economy over $4 billion per day, with 21% of world oil and 25% of LNG trade at risk[2].

Historically, similar closures in the region have persisted for months without rapid resolution, framing the current 8% market probability as a realistic assessment rather than an outlier. The last surge in traffic occurred only after a deal to halt the US-Iran war, a condition not yet met[4]. Traders note that even when the strait briefly reopened, actual transit figures remained low, with real counts likely between 10–15 ships daily rather than the claimed higher ranges[7]. IMF PortWatch data from late June 2026 shows a 7-day moving average of just 13.14, far below the 60-ship threshold required for this market to resolve as “Yes”[8].

Key catalysts to monitor include President Trump’s explicit stipulation that strait reopening is a prerequisite for any ceasefire with Tehran, a condition with minimal progress so far[3]. The US has declared a naval blockade against Iran, while Tehran has implied it may have laid mines in the strait, further complicating any near-term reopening[3]. Traders should watch for announcements on peace negotiations, naval blockade adjustments, or Iranian de-escalation moves, as these dependencies directly influence whether transit calls can reach the required level before the 7 July 2026 settlement window closes[3]. On Polymarket, this contract trades on USDC via Polygon using conditional tokens, pricing the 8% chance that IMF PortWatch will publish the necessary data within the timeframe.
