Strait of Hormuz traffic returns to normal by July 31?
I assess a 28% probability that IMF Portwatch will report a 7-day moving average of transit calls for the Strait of Hormuz at or above 60 on at least one date by July 31, 2026; the remaining chance is dominated by persistent security and commercial frictions that have kept traffic below pre-crisis norms.
Analysis
We lack direct IMF Portwatch figures in the prompt, but the market-implied probability (Yes ~21.5%) and the proximity of the deadline (less than four weeks remaining) together imply the market thinks recovery to a 7-day MA >=60 is possible but not likely. With only a few weeks left, any recovery must be rapid and sustained for at least a week to register as a qualifying 7-day average, which raises the bar compared with a gradual return over months.
Operationally, traffic through the Strait of Hormuz is sensitive to short-term security incidents, insurance and chartering decisions, and availability of naval escorts or convoys; these levers can cause sudden increases or decreases in transit calls. If regional tensions de-escalate rapidly or if operators judge risk to have fallen enough to reverse rerouting decisions, traffic could rebound quickly, but commercial hesitancy and higher voyage costs typically produce lagged responses.
Market sentiment appears skeptical but not dismissive; the market price around 22% indicates some participants see meaningful upside from a plausible near-term improvement in conditions, while a larger share expects continued suppression or slow recovery. Historical patterns from previous disruptions show that shipping flows often resume gradually as confidence and insurance terms normalize, so a one-week spike to push a 7-day moving average above 60 is relatively unlikely without a clear, sustained catalyst such as a durable ceasefire, a reduction in attacks, or policy moves reducing premiums and deterrence costs.
Arguments
For
- A clear, sustained de-escalation in the Gulf would quickly restore operator confidence and pull traffic back into the Strait.
- Market participants could rapidly reverse prior rerouting decisions if insurance pricing drops significantly, leading to a quick uptick in daily calls.
- International naval protection initiatives or visible convoy operations would be an immediate catalyst for restored transits.
- Seasonal or idiosyncratic demand spikes for oil and refined product shipments in July could force a temporary return to the shortest routing.
- A small number of high-frequency commercial operators resuming normal transits could move the 7-day average above 60 even without broad-based recovery.
- Late data revisions published by IMF Portwatch within the window could create or reveal a qualifying 7-day average.
Against
- Persistent security threats and sporadic attacks continue to make operators cautious about resuming normal routing through the Strait.
- High insurance and bunker costs from rerouting alternatives may remain acceptable compared with perceived risks, keeping volumes depressed.
- Shipping industry behavioral change can be sticky, with firms reluctant to reverse rerouting until they see a sustained multi-week calm.
- Even a partial recovery that is patchy day-to-day may fail to lift the 7-day moving average above the 60 threshold.
- IMF Portwatch data publishing cadence or recording conventions could mean recent increases are not reflected in time to qualify.
- A localized incident in July could rapidly undo any fragile recovery, preventing a qualifying run of seven days.
Key drivers
- Rapid de-escalation of regional hostilities or a formal ceasefire would encourage immediate routing back through the Strait.
- Substantial reductions in war-risk insurance premiums would lower voyage costs and prompt operators to resume normal routes.
- Deployment of effective and visible naval escorts or international convoys would materially reduce perceived transiting risk.
- A surge in chartering demand for crude or refined products around July could push operators to accept remaining risk and restore transit volumes.
- Revisions or late postings to IMF Portwatch data could retroactively create qualifying 7-day averages within the market window.
- Commercial decisions by a few large tanker operators to re-route ships back through the Strait could have outsized impact on daily counts.
Risk factors
- Renewed missile, drone, or asymmetric attacks targeting transiting ships would immediately suppress transit calls.
- Sustained high war-risk or kidnap-and-ransom premiums would keep cargo owners and charterers favoring longer reroutes.
- Continued use of alternative passages and longer voyages as a new operational norm would reduce incentive to return quickly.
- PortWatch reporting gaps, delayed uploads, or data anomalies could prevent a qualifying 7-day average from being published in time.
- Political escalation or sanctions-related disruptions that constrict Gulf trade flows would reduce daily transits.
- A short-lived recovery that fails to last seven consecutive days would not register as a qualifying 7-day moving average.
Scenarios
Best case
A rapid and credible de-escalation occurs, insurance premiums fall, and at least some major operators resume normal routing; daily transit calls rise sharply and sustain levels sufficient for a 7-day moving average >=60 at least once before July 31, producing a Yes resolution.
Most likely
Conditions remain mixed with occasional short-lived upticks in traffic but not a sustained seven-day run above 60; isolated recoveries may occur but are likely too brief or uneven to produce a qualifying 7-day average, yielding a No outcome with moderate probability.
Worst case
Security incidents or geopolitical escalation persist or worsen, insurance and operating costs remain elevated, reporting windows miss any short upticks, and daily transit calls stay depressed so no 7-day moving average reaches 60, resulting in a No resolution.
