Strait of Hormuz traffic returns to normal by end of June?
Given the short time window, ongoing geopolitical risk, and likely depressed transit volumes relative to historical norms, I assess a low but non-negligible chance (20%) that IMF Portwatch's 7-day moving average for the Strait of Hormuz will reach or exceed 60 by June 30, 2026.
Analysis
There is limited publicly available, up-to-date daily transit-count data in the prompt, so I anchor part of this assessment to the market-implied probability (Yes = 9.5%) while forming an independent view based on structural drivers. Reaching a 7-day moving average of 60 requires sustained daily transit counts above that threshold for at least a week or a series of high daily spikes sufficient to lift the moving average; with only ten days remaining, the window for such a sustained rise is narrow and requires an abrupt and sustained reversal of any depressed traffic levels.
Geopolitical dynamics are the dominant determinant: ongoing regional tensions, recent Houthi/Red Sea and Gulf incidents since 2023, and insurance/war-risk premiums have encouraged some rerouting and reduced tanker and commercial transits through Hormuz in prior years, which plausibly keeps the current 7-day average below the historical norm; however, episodic ceasefires, de-escalation, or a temporary lull in attacks could restore confidence quickly and trigger a concentrated rebound in transits. Operational and commercial factors also matter: port congestion elsewhere, seasonal increases in crude/oil product movements, or a transient spike in bulk/container schedules could push weekly counts up if carriers choose the shortest route.
Data and reporting mechanics add non-trivial upside risk: IMF Portwatch revises historical data, and a retrospective upward correction to previously published daily counts could qualify a date within the window even if real-time operations look subdued; conversely, any data integrity issues or delayed publication could either postpone resolution or leave the market effectively locked to the current low probability. Balancing these considerations, I find the market’s sub-10% pricing reasonable but slightly underestimates the non-zero chance of a rapid rebound or a reporting-driven correction before June 30, so I set the probability at 20% to reflect both the short time horizon and possibility of abrupt changes or revisions.
Arguments
For
- A temporary lull or de-escalation in regional hostilities could quickly restore carrier confidence and raise daily transits above 60 for a week.
- Seasonal or cyclical increases in crude exports or bulk shipments could produce a concentrated rise in daily arrivals sufficient to lift a 7-day average.
- IMF Portwatch data revisions or late-added vessel reports could retroactively increase published daily counts and create a qualifying 7-day average.
- Operational shortcuts or schedule bunching by shipping lines seeking to reduce delays elsewhere could transiently spike transit calls through Hormuz.
Against
- Persistent geopolitical risk and the threat of further attacks make carriers reluctant to resume pre-crisis routing through the Strait of Hormuz.
- High war-risk and insurance premiums incentivize continued rerouting around the Cape of Good Hope, lowering baseline transit counts.
- With only ten days remaining, even a modestly depressed current 7-day average is difficult to lift to 60 without an unlikely, sustained surge.
- If IMF Portwatch reporting has gaps, delays, or conservative vessel inclusion compared with other trackers, published counts may understate true traffic and never reach the threshold.
Key drivers
- Current and near-term regional security environment in the Gulf of Oman and Strait of Hormuz, especially the cadence of maritime attacks or escalatory incidents.
- Commercial carrier routing choices driven by insurance/war-risk premiums and bunker costs, which determine whether ships return to the shortest route.
- Global oil and commodity demand fluctuations that could temporarily raise tanker and bulk transits through the strait.
- IMF Portwatch reporting practices and the potential for data revisions or late-added vessel reports that could retroactively raise the 7-day moving average.
Risk factors
- A fresh wave of attacks or a high-profile incident that drives immediate rerouting away from Hormuz and depresses daily counts.
- Sustained high insurance costs and carrier risk aversion keeping traffic diverted for weeks or months.
- Data publication delays or gaps that prevent a qualifying 7-day average from ever appearing within the market window.
- Structural changes in trade routes (e.g., persistent rerouting around Africa) that permanently reduce baseline transit volumes.
Scenarios
Best case
A short, demonstrable de-escalation occurs (for example, a formal pause or local ceasefire), carriers react by returning to transit through Hormuz, daily calls rise rapidly above 60, and IMF Portwatch publishes either real-time counts or upward revisions that produce a 7-day moving average of 60 or greater before June 30.
Most likely
Regional tensions remain elevated with intermittent incidents, carriers largely maintain precautionary rerouting and elevated premiums, daily transit counts remain under the historical norm, occasional small spikes occur but not sustained long enough to lift the 7-day moving average to 60, leading to a No outcome with a low probability of a last-minute qualifying spike or data revision.
Worst case
A fresh round of maritime attacks or heightened state-level tension drives immediate rerouting and suppression of traffic, IMF Portwatch data remain low or delayed, and no 7-day moving average reaches 60, yielding a clear No resolution.
