Strait of Hormuz traffic returns to normal by July 31?
I assess a 48% probability that IMF Portwatch will report a 7-day moving average of transit calls for the Strait of Hormuz at or above 60 on or before July 31, 2026, reflecting a roughly even chance with a slight tilt toward stagnation given ongoing regional risks and the moving-average requirement.
Analysis
Market-implied probability (Yes ~42.5%) and substantial event volume indicate active trading and meaningful disagreement about pace of recovery; I start from that market signal but adjust modestly upward because the 60-call threshold is attainable from normal pre-disruption baselines and occasional short-term rebounds can lift a 7-day average into range. The resolution rule requires a 7-day moving average at or above 60, which is a stricter test than a single-day spike and means daily counts need to be sustained at roughly >=60 ships for a week or higher if previous days are lower, making timing and persistence crucial.
Historically, the Strait of Hormuz is one of the world's busiest chokepoints for tankers and general cargo, so absent sustained escalation the channel tends to revert toward pre-crisis traffic levels; if the principal inhibitors (targeted attacks, insurance spikes, or official closures) have abated or been mitigated by naval escorts and insurance-market normalization, returning to a 7-day moving average >=60 by late July is plausible. Conversely, even isolated incidents or renewed targeting of merchant shipping can depress traffic quickly because carriers reroute, slow steam, or delay transits until risk and insurance conditions improve.
Key external drivers that will determine the outcome in the coming five weeks include the security environment (incidents, state-to-state escalations, and visible naval escort operations), commercial responses (P&I and hull war-risk premiums and owners' routing choices), and broader demand-side factors (seasonal crude and LNG flows, and scheduled commercial voyages); data quirks and IMF Portwatch reporting cadence and any late revisions also matter because the market resolves on published moving averages. Given these mixed forces and the limited time window to achieve a sustained 7-day average, I view the probability as nearly coin-flip but slightly favoring No because geopolitical tail risks remain non-negligible and the moving-average requirement raises the bar for a quick, sustained recovery.
Arguments
For
- Pre-crisis baseline traffic through the Strait of Hormuz was comfortably above 60 daily transits, so a return to that level is structurally plausible if disruptions abate.
- Multinational naval escorts and stronger intelligence-sharing have previously lowered perceived transit risk and can prompt a quick resumption of normal movements.
- Commercial pressure to clear backlogs and deliver cargoes can drive concentrated spurts of transits that lift a 7-day average into range.
- Stabilizing oil and LNG production schedules and contract-driven sailings provide a demand floor for tanker transits through the strait.
- IMF Portwatch allows revisions within the market timeframe, which could validate a qualifying 7-day average if earlier days are later adjusted upward.
Against
- Any renewed attacks or provocative acts in the Gulf would quickly depress transits as owners choose avoidance or slow steaming.
- Persistently elevated insurance premiums could keep operators rerouting around Africa or consolidating sailings, suppressing daily counts.
- The 7-day moving average requirement is stricter than a single-day spike and requires sustained recovery over a week, reducing the chance of a late, short-lived rebound qualifying.
- Commercial caution and macroeconomic softness could reduce shipping demand, delaying a full recovery of transit counts.
- Counting and reporting limitations mean some actual transits might not be reflected in IMF Portwatch quickly enough to affect the moving average before July 31.
Key drivers
- Level of regional security incidents and whether any new attacks or seizures occur that deter transits.
- Visible naval escorts or multinational security operations that reduce perceived risk and encourage normal transit patterns.
- Insurance premiums and war-risk surcharges that influence owners' decisions to transit versus reroute or delay.
- Commercial demand for oil and gas exports from Gulf producers which drives tanker transit frequency through Hormuz.
- Portwatch reporting cadence, data completeness, and any in-scope revisions that can affect the 7-day moving average calculation.
Risk factors
- A fresh episode of targeted attacks or a state-level escalation in the Gulf that prompts rerouting or suspension of transits.
- Rapid increases in war-risk insurance costs that cause carriers to avoid the route or consolidate sailings.
- Administrative or port-side restrictions imposed by Gulf littoral states in response to security concerns.
- Significant delays in IMF Portwatch publishing or data integrity issues that compress the effective window for achieving the moving-average threshold.
- Global demand shocks that reduce tanker liftings from Persian Gulf producers and lower transit frequencies.
Scenarios
Best case
Security incidents remain rare, naval escorts and insurance markets stabilize quickly, carriers resume full transit schedules, and IMF Portwatch reports a sustained run of daily counts >=60 such that a 7-day moving average meets or exceeds 60 well before July 31.
Most likely
Traffic gradually recovers with intermittent days at or above 60 but the 7-day moving average only edges close to the threshold and ultimately fails to sustain at or above 60 by July 31, leading to a No resolution while keeping the possibility of a delayed recovery beyond the market window alive.
Worst case
A new round of targeted attacks or a regional escalation occurs, insurance costs spike, carriers avoid the strait or delay sailings, and IMF Portwatch never records a sustained 7-day average at or above 60 through July 31.
