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, has experienced significant disruption since mid-2024 owing to Houthi attacks on commercial shipping and subsequent regional tensions. The market asks whether daily transit calls will recover to a 7-day moving average of 60 or higher by mid-June 2026—a threshold representing approximate pre-disruption traffic levels. IMF Portwatch data, the sole arbiter here, tracks container, bulk, tanker, and general cargo arrivals; the resolution hinges on a single publication meeting the criterion, not sustained recovery.

Historical precedent suggests recovery timelines vary sharply depending on catalyst type. The 2011 Suez Canal closure lasted eleven days; the 2022 Ever Given blockage saw normalisation within weeks once the vessel cleared. However, the Hormuz situation differs fundamentally: it involves non-state actors with demonstrated persistence and no clear negotiated endpoint. Comparable cases—the 1980s tanker war and 2019 tensions—show that regional instability can suppress traffic for months. The 9% implied probability across major platforms reflects this uncertainty, though Polymarket's decimal-odds display (approximately 1.10) and Kalshi's percentage format may obscure how tight the margin is; Betfair and Smarkets show similar probabilities but diverge on fee structures, with Kalshi charging 2% on net winnings versus Betfair's variable commission.

Traders should monitor three dependencies: Houthi operational capacity and any ceasefire negotiations (Reuters and maritime security bulletins remain primary sources), insurance and re-routing costs that may sustain alternative pathways even if attacks cease, and IMF Portwatch publication schedules. A sudden diplomatic breakthrough or sustained US-led naval deterrence could compress the timeline; conversely, escalation would extend it well past June 2026.
