Strait of Hormuz traffic returns to normal by June 15?

Platform comparison

Market context

The Strait of Hormuz handles roughly one-third of global seaborne oil trade, and this market tracks whether daily vessel transits will recover to a 7-day average of 60 or more ships by mid-June 2026. The threshold represents a return to pre-disruption baseline traffic; current volumes sit materially below that level, reflecting months of Houthi attacks on commercial shipping, regional tensions, and consequent rerouting via the Cape of Good Hope. IMF Portwatch data—the sole authoritative source for settlement—captures container, tanker, bulk, and general cargo arrivals; the 17% implied probability reflects trader scepticism that normalisation occurs within eighteen months.

Historical precedent matters here. The 2019 tanker attacks saw Hormuz traffic dip sharply but recover within weeks once insurance and security protocols stabilised. The current disruption, however, has proven more entrenched: Houthi capability has expanded, regional powers have hardened positions, and shipping lines have restructured routes into their operational planning rather than treating diversions as temporary. Comparable chokepoint disruptions—Suez Canal blockage in 2021, Panama Canal drought in 2023—took three to six months to normalise, though neither faced sustained military pressure. The 17% probability suggests traders view a return to 60 daily transits as unlikely absent either a major geopolitical settlement or a decisive shift in Houthi operational capacity.

Traders should monitor US and Iranian diplomatic signals, which could alter regional stability calculus, and any announcements from shipping insurers regarding Hormuz corridor premiums. Kalshi's fixed-odds format (currently around 5.8 decimal odds for YES) differs from Polymarket's AMM pricing, whilst Betfair and Smarkets offer tighter spreads on binary outcomes; KYC requirements vary across platforms, affecting liquidity depth on niche geopolitical markets. IMF Portwatch publishes weekly, creating discrete settlement windows where a single week of elevated traffic could trigger resolution.
