Strait of Hormuz traffic returns to normal by end of June?

Platform comparison

Market context

The Strait of Hormuz remains one of the world's most strategically volatile chokepoints, with roughly 21% of global petroleum transit passing through its waters annually. The 18% YES probability on Polymarket reflects genuine uncertainty about whether daily ship transits will recover to a 7-day moving average of 60 arrivals by June 2026—a threshold that represents near-normal operations. Currently, the conditional token pair trades on Polygon with USDC collateral, pricing the market's assessment that sustained normalcy remains unlikely within the settlement window.

Historical precedent suggests recovery timelines from major Hormuz disruptions extend well beyond initial expectations. The 2019 tanker attacks saw transit volumes suppress for months despite no formal blockade, whilst the 2022 Houthi drone campaign created persistent uncertainty that depressed traffic for extended periods. Even when direct military incidents cease, shipping insurers and operators maintain elevated risk premiums, delaying full normalisation. The current geopolitical configuration—with Iranian-aligned forces maintaining asymmetric capabilities and regional tensions unresolved—differs from previous episodes where clear diplomatic off-ramps existed.

Traders monitoring this contract should track announcements from Iran's nuclear negotiations, US sanctions policy shifts, and Houthi operational tempo, particularly any escalation in attacks on commercial vessels. Recent reporting from Reuters in January 2025 documented continued drone and missile threats despite international naval presence. The IMF Portwatch data itself lags by several days, meaning traders cannot react in real-time to disruptions. Any major regional conflict expansion or conversely, a comprehensive sanctions relief agreement, would likely shift probabilities sharply.
