Strait of Hormuz traffic returns to normal by September 15?

Platform comparison

Market context

The Strait of Hormuz, through which roughly one-fifth of global oil passes daily, has experienced significant disruption since late 2024 owing to regional tensions and Houthi attacks on commercial shipping. The market asks whether daily transit calls will recover to a 7-day moving average of 60 or above by mid-September 2026—a threshold representing approximate pre-disruption normality. Current crowd pricing at 8% YES suggests traders view sustained recovery as unlikely within the settlement window, despite the 20-month timeframe.

Historical precedent offers limited comfort for the bullish case. The 2022 Russia-Ukraine war disrupted Black Sea grain corridors for months; the 2011 Libyan conflict reduced Mediterranean transit substantially; and the 2019 tanker attacks near Hormuz took roughly six months to stabilise shipping patterns once diplomatic channels reopened. Each instance required either military de-escalation, insurance-cost normalisation, or rerouting infrastructure to absorb traffic. Current regional actors show no clear off-ramp, and alternative routes (Suez, Cape of Good Hope) remain congested, suggesting any recovery would be gradual rather than sharp.

Traders should monitor three variables through 2026: announcements of US or international naval commitments to corridor protection; any ceasefire or diplomatic breakthrough in Yemen or broader Iran-linked tensions; and published IMF Portwatch data itself, which lags real-world conditions by several days. Reuters and Lloyd's List have reported sporadic upticks in transits during lulls in attacks, but these have not sustained above historical baselines. The 8% probability reflects a market view that geopolitical resolution within 20 months remains a low-probability event relative to continued disruption or slow, partial recovery.
