Strait of Hormuz traffic returns to normal by July 31?
I assess a low but non-negligible chance (12%) that IMF Portwatch will publish a 7-day moving average of transit calls for the Strait of Hormuz at or above 60 on or before July 31, 2026; the short remaining window and persistent security, insurance, and routing frictions make recovery to 'normal' within three weeks unlikely but not impossible if a rapid de-escalation or data revision occurs.
Analysis
Market prices (Yes ~4.5%) imply that traders believe a return to the historical traffic threshold is very unlikely, and that impression is consistent with a recent multi-week period of below-threshold counts that would require a sustained surge in arrivals to produce a 7-day moving average >=60 before July 31. With only about three weeks remaining in the market window, achieving the 7-day moving average requires both a rapid, sustained rise in daily transits and timely publication of that rise by IMF Portwatch; data revisions up through the period can also retroactively produce a qualifying 7-day average, which slightly increases the feasible pathways to resolution in favor of Yes. Geopolitical and security dynamics remain the principal determinant: a sudden diplomatic breakthrough, coordinated naval escort operations, or a precipitous decline in regional incidents could allow shipowners to resume normal routings quickly, while any ongoing attacks, detentions, or insurance hikes would sustain rerouting and suppressed counts. Operational and commercial incentives also matter—short-term spikes in oil demand or chartering that force tankers back through the Strait could push counts upward, whereas structural rerouting habits, elevated war-risk premiums, and port congestion elsewhere make a full, sustained return to the pre-disruption baseline within weeks an uphill task.
Arguments
For
- A rapid diplomatic de-escalation could lead to immediate resumption of routings through the Strait and a quick rise in transit counts.
- Coordinated naval escort programs or guarantees of safe passage could lower perceived risk and draw ships back into the corridor.
- A sudden surge in tanker demand driven by supply shocks could force rerouting back to the Strait to meet schedules.
- IMF Portwatch data revisions published within the eligible window could retroactively create a 7-day average at or above 60.
- Commercial pressure from shippers and energy companies to shorten voyages could incentivize a quick return to the shorter Hormuz route.
Against
- Ongoing regional hostilities or repeated attacks will keep commercial operators away and suppress daily transit counts.
- Sustained high war-risk insurance premiums make alternate longer routes economically preferable and slow any return to normal.
- Behavioral inertia among shipowners and charterers means routing practices changed months ago may not reverse within weeks.
- Portwatch reporting lags, incomplete vessel reporting, or conservative counting practices could delay or undercount actual transits.
- Even if single-day arrivals spike, the 7-day moving average requirement raises the bar and short-lived rallies are unlikely to qualify.
- Logistical constraints such as port congestion or lack of pilots could prevent rapid throughput increases even with improved security.
Key drivers
- Immediate security situation in and around the Strait, including any attacks, seizures, or naval incidents that would deter transits.
- Diplomatic developments between regional actors (Iran, Gulf states) and external navies that could de-escalate tensions quickly.
- Insurance and war-risk premium levels that determine whether shipowners accept routes through the Strait or choose longer alternates.
- Near-term fluctuations in crude and refined product demand that influence tanker routing decisions and frequency of voyages.
- Timing and content of IMF Portwatch publications and any within-period data revisions that could produce a qualifying 7-day average.
- Operational constraints such as port congestion, pilotage availability, or logistical bottlenecks that affect the ability to increase daily transits rapidly.
Risk factors
- A sustained series of hostile incidents or credible threats that keep commercial traffic routed away from the Strait.
- High insurance premiums and charterer reluctance that prevent rapid redeployment of ships to the Strait.
- Persistent operational disruptions at nearby ports or pilotage services that limit throughput even if security improves.
- Delayed IMF Portwatch publication schedules or incomplete reporting that prevent a qualifying 7-day average from being recorded in time.
- Data integrity issues or later revisions that could remove or alter a candidate qualifying value outside the permitted revision window.
- A mismatch between temporary spike days and the requirement for a 7-day average, meaning short rallies may not suffice to reach the threshold.
Scenarios
Best case
A swift, clear de-escalation—backed by diplomatic announcements, visible multinational naval escorts, and a rapid drop in insurance costs—produces a sustained daily arrival surge that is published by IMF Portwatch and yields a 7-day moving average >=60 before July 31, resolving the market to Yes.
Most likely
Security conditions remain mixed with episodic improvements but no sustained normalization, resulting in occasional daily upticks but not a long enough or large enough run of arrivals to lift the 7-day moving average to 60 before July 31, leading to a No resolution while leaving a small chance of late-period qualifying data or revisions.
Worst case
Hostilities or targeted actions continue or intensify, insurance remains prohibitively expensive, and IMF Portwatch data continue to show sub-60 7-day averages (or reporting issues prevent a qualifying publication), resulting in a No resolution with no qualifying value recorded by the deadline.
