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 transits daily, has experienced significant traffic disruption since mid-2024 owing to Houthi attacks on commercial shipping and subsequent coalition military operations. The market asks whether a 7-day moving average of arriving vessels will recover to 60 daily calls—a threshold representing near-normal pre-disruption volumes—by mid-June 2026. Current crowd pricing at 9% implied probability on Polymarket reflects deep scepticism about such a recovery within the settlement window, though comparable books diverge notably: Kalshi's decimal odds format and stricter US regulatory framework have historically priced geopolitical risk differently than Polymarket's broader international user base, whilst Betfair and Smarkets' commission structures (typically 2–5% versus Polymarket's variable fees) can shift marginal trader participation on longer-dated events.

Historical precedent offers mixed signals. The 2019 tanker attacks and 2020 Soleimani assassination saw Hormuz traffic decline sharply but recover within 4–8 weeks once insurance and routing protocols stabilised. However, the current Houthi campaign has proven more sustained and operationally complex, with attacks continuing into 2025 despite US and UK naval presence. IMF Portwatch data, the settlement source, lags real-time reporting by 1–2 weeks, creating timing risk for traders.

Key catalysts include any ceasefire agreement involving Yemen's Houthis, escalation or de-escalation of US–Iran tensions, and insurance premium adjustments that determine shipping route economics. Recent reporting from Lloyd's List and Splash247 indicates some rerouting via the Cape of Good Hope remains economically viable even at current oil prices, potentially suppressing Hormuz recovery below the 60-call threshold through June 2026.
