Strait of Hormuz traffic returns to normal by June 15?

Platform comparison

Market context

The Strait of Hormuz, through which roughly one-fifth of global seaborne oil passes, has experienced significant traffic disruption since late 2023 owing to Houthi attacks on commercial vessels and subsequent coalition naval operations. The market requires a 7-day moving average of 60 daily transit calls—container, tanker, dry bulk, and general cargo vessels combined—as published by IMF Portwatch to resolve affirmatively. Pre-disruption baseline traffic typically ranged between 80–100 daily transits, meaning the 60-call threshold represents a partial recovery rather than full normalisation, yet the 17% implied probability on Polymarket suggests traders assess this as unlikely within the next eighteen months.

Historical precedent offers limited comfort. The 2019 tanker attacks saw traffic recover within weeks once insurance and routing protocols stabilised; however, the current campaign has proven more sustained and geopolitically entrenched. The January 2024 Houthi escalation prompted several major shipping lines to reroute via the Cape of Good Hope, a decision with structural cost implications that discourage rapid reversal. Kalshi's decimal-odds format (currently around 5.88 for YES) and Smarkets' commission structure may appeal differently to traders hedging shipping exposure versus pure speculation, though all three platforms require KYC verification for UK users.

Catalysts include ceasefire announcements in the Yemen conflict, shifts in US or UK naval posture, and insurance premium adjustments that signal confidence restoration. Recent reports from Lloyd's List and Reuters indicate shipping companies remain cautious despite periods of reduced attacks. Any sustained two-week window without major incidents could trigger rapid repricing, though the market's low probability reflects scepticism that such stability materialises by mid-June 2026.
