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 and the US maintain a deepening deadlock, with transit counts hovering near zero for weeks despite a brief reopening in mid-April. This real-world stagnation underpins the current 9% crowd-implied probability that traffic will return to normal by 7 July 2026, a threshold requiring a 7-day moving average of at least 60 daily arrivals. Historical precedents from the 2026 Iran war show that even after the 8 April ceasefire, commercial flows remained at a trickle due to persistent routing uncertainty and war-risk insurance gaps, suggesting that a sudden surge to 60 daily transits is highly improbable without a major geopolitical shift[3][8].

Traders must monitor the IMF PortWatch data releases, specifically the 7-day moving average figures, alongside any announcements regarding war-risk insurance coverage or missile-defence corridors that could unlock tanker and container routes. Recent MarineTraffic data indicated a modest recovery with 25 vessels crossing on 18 June, the highest since mid-April, yet this remains far below the 60-target and follows a period where the strait was officially declared closed[2][4]. The divergence between platforms is stark here: Polymarket users trade decimal odds reflecting this 9% probability with minimal KYC, whereas Kalshi or Betfair traders face stricter identity verification and fee structures that may alter the effective payout, while Smarkets offers a different fee model but requires deeper liquidity to match the implied probability[1][7].

The primary catalyst remains the resolution of the US-Iran deadlock, as continued surcharges on shipping to the Persian Gulf and expiring war-risk cover continue to deter owners despite Mediterranean Shipping Company pushing sharp rate hikes[1]. Without a formal agreement to guarantee safe passage or a significant drop in regional tension, the 60-arrival threshold is unlikely to be met before the settlement window closes, reinforcing the market’s lean toward a “No” resolution. The current data suggests that while traffic has shown a marginal recovery, the structural barriers preventing normal operations remain intact, making the July target a distant prospect[5][9].
