Strait of Hormuz traffic returns to normal by July 31?
I assess a roughly 30% probability that IMF Portwatch will show a 7-day moving average of Strait of Hormuz transit calls at or above 60 on at least one date by July 31, 2026, reflecting limited time for sustained recovery but non-negligible upside from rapid de-escalation or demand spikes.
Analysis
The market threshold requires a 7-day moving average of transit calls equal to or above 60 for at least one date by July 31, 2026, which in practice means roughly a sustained run of daily transit counts near or above that level for a week. The market-implied probability (Yes at 26%) already discounts a quick return to 'normal' and reflects both the short remaining time window and historically fast-but-incomplete recoveries after Gulf incidents; I place slightly more weight on a modest chance of recovery (30%) because short-term diplomatic or operational fixes can rapidly restore traffic volumes.
From a security and operational perspective, the primary determinants are the near-term trajectory of regional tensions, the frequency and severity of maritime incidents, and the willingness of operators and insurers to re-route or resume normal passage through the Strait. Historically, shipping flows can bounce back within weeks to months after de-escalation because commercial incentives favor the shortest route, but persistent threats, targeted attacks on merchant ships, or a sustained convoy/escort requirement raise costs and can keep traffic depressed beyond a month.
On the demand and structural side, global tanker and dry-cargo demand, OPEC production decisions, seasonal trade patterns, and the availability/attractiveness of alternative routes (e.g., longer voyages around the Cape of Good Hope or using pipelines) will matter; higher oil flows or a spike in demand could push daily calls up quickly, while sustained high insurance premiums and longer voyage times work in the opposite direction. Finally, the market must resolve to IMF Portwatch data: reporting lags, intra-period revisions that are accepted, or minor data integrity corrections could materially affect whether the 7-day moving average crosses 60 even if operational conditions are only marginally improved, which introduces an additional source of near-term uncertainty.
Arguments
For
- A rapid diplomatic de-escalation or successful security measures could prompt operators to resume normal routes within days, lifting the 7-day average above 60.
- A sudden uptick in oil exports or spot charter demand could increase tanker transits through the Strait on short notice.
- Commercial incentives to minimize voyage distance mean many ships will revert to the Strait as soon as perceived risk and insurance costs fall.
- IMF Portwatch accepts within-period revisions, so late reporting of previously missed transits could retroactively lift the 7-day moving average.
Against
- If attacks or harassment persist or escalate, operators will continue to avoid the Strait or reduce call frequency, keeping the average below 60.
- High insurance premiums and crew risk aversion can make alternative longer routings economically preferable for weeks or months.
- Structural changes such as increased pipeline flows or long-term rerouting established during the disruption could permanently lower transit baselines.
- With only a few weeks remaining, even a partial recovery may be insufficient to generate the sustained seven-day average required for a 'Yes' resolution.
Key drivers
- Short-term trajectory of regional security incidents and whether a clear de-escalation occurs.
- Commercial shipping decisions on whether insurers and charterers accept transit risk versus rerouting costs.
- OPEC and major producers' crude and product output decisions that change tanker volumes through the Strait.
- Seasonal trade flows and spot demand for container and dry-bulk services that influence aggregate transit counts.
- Availability and economics of alternative routes or pipeline bypasses that permanently reduce passage demand.
- Timeliness, completeness, and any within-period revisions to IMF Portwatch reporting that can change moving averages.
Risk factors
- A new or renewed wave of maritime attacks or targeted incidents that keep transits low through July.
- Sustainedly elevated marine insurance premiums that make the Cape route more economical for many operators.
- Permanent commercial rerouting or increased pipeline throughput that reduces baseline transit volumes.
- Delayed or incomplete IMF Portwatch reporting or a corrective data revision outside the allowable window that complicates resolution.
- Rapid increase in shipping congestion or port-side bottlenecks that reduce transits through the Strait despite demand.
- Unforeseen weather or navigational hazards that temporarily depress daily transit counts during the measurement window.
Scenarios
Best case
A rapid and verifiable de-escalation combined with visible naval escorts and sharp declines in insurance costs leads operators to resume normal routing, producing a week-long run of daily transit counts that pushes the 7-day moving average above 60 before July 31.
Most likely
Incremental improvement in security and demand produces occasional spikes in daily transits but not a sustained seven-day run at or above 60 before July 31, so the market resolves to 'No', although late reporting or a short-lived surge keeps the chance of 'Yes' non-negligible.
Worst case
A fresh round of incidents or sustained harassment leads to continued avoidance of the Strait, insurance remains prohibitively expensive, and traffic stays depressed so no 7-day moving average reaches 60, resulting in a clear 'No'.

What will the median home value in Miami be on September 30?
AI85%MKT8%Edge+77Hidden GemI assess an 85% probability that Miami's median home value (Parcl price-per-sqft × 2100) will be less than $1,017,000 on September 30, 2026, because a $1M+ citywide median would require an outsized, broad-based surge above typical per-square-foot medians and would be inconsistent with likely citywide housing composition and macro constraints.
