Strait of Hormuz traffic returns to normal by July 7?

Platform comparison

Market context

The Strait of Hormuz remains effectively closed to commercial shipping as Iran reversed its brief reopening following reported attacks, leaving global energy markets in a state of high tension with oil prices volatile and freight indices spiking. This real-world paralysis underpins the current 8% crowd-implied probability that transit calls will return to a 7-day moving average of 60 or above by July 7, 2026.

Historical precedents from the 2020–2021 period show that even during severe geopolitical friction, the strait rarely sustains a complete shutdown for more than a few weeks unless direct military conflict escalates; however, the current suspension since late February 2026 marks an unusually prolonged disruption, with recent data showing only 25 vessels crossing on 18 June after a near-standstill for weeks[3][4]. This extended closure contrasts sharply with typical crisis patterns, suggesting the low probability reflects genuine concern that the 60-ship threshold is unlikely to be met before the settlement window closes.

Traders should monitor announcements from the U.S. Central Command regarding merchant ship transits and any shifts in Iran’s maritime policy, as 55 merchant ships recently crossed with over 17 million barrels of oil despite the broader closure[9]. Additionally, watch for updates on war risk insurance coverage and freight rate adjustments, as Shanghai container futures have hit consecutive limit ups amid carrier-led rate hikes driven by Hormuz fears[1]. On platforms like Polymarket versus Kalshi or Betfair, divergence arises in decimal odds versus implied probability displays, fee structures that can erode thin margins, and KYC requirements that may limit access for international participants researching this specific market.
