Strait of Hormuz traffic returns to normal by end of June?
Given the 7-day moving-average requirement and the short time left, a return to a Portwatch 7-day average >=60 by June 30 is unlikely but not impossible; I assess an 8% probability of a 'Yes' outcome.
Analysis
The primary structural constraint is timing: the market requires a 7-day moving average >=60 on any date up to June 30, and there are only a few days remaining to form such a seven-day window, which means most of the average is already fixed by prior daily counts. If the most recent published 7-day moving average is substantially below 60, a single-day spike cannot by itself produce a qualifying 7-day average unless preceding days are already near the threshold or revisions are applied to earlier days within the allowed window. Conversely, if the existing recent seven-day stretch is close to 60, a modest but sustained increase in daily transits could push the average over the line, but that scenario requires favorable prior data that the market price likely reflects as absent.
Market sentiment, as reflected by the current price (Yes ~2.35%), implies participants collectively think the chances are extremely low; the very low price also indicates either broad confidence that traffic remains depressed or concentration of information among a few large traders. The high event volume suggests significant capital has already been committed to the 'No' outcome, which can depress the implied probability below a rational baseline if traders are asymmetric in access to on-the-ground information or if liquidity-driven selling dominated early. I treat the market price as a strong signal but adjust upward because of two sources of upside risk: permissible data revisions up to publication on June 30 and the possibility of a short window of anomalous traffic (e.g., convoy scheduling or concentrated tanker movements).
External drivers matter a lot in the remaining days: rapid de-escalation of regional tensions, a sudden surge in crude liftings that route ships through the Strait, or coordinated scheduling (e.g., tankers timed to transit through a narrow interval) could cause multiple higher daily counts in a row and lift the 7-day average, but these events are rare on such short notice. On the flip side, continued security concerns, ongoing rerouting of vessels to alternative passages, and continuing operational restrictions at Gulf ports all push expected traffic lower. Given the short horizon, the most realistic route to 'Yes' is either (a) the already published recent daily series is much closer to 60 than market participants believe, (b) several higher-than-normal transit days occur in immediate succession, or (c) upward revisions to previously published daily counts within the allowed timeframe materially raise the 7-day average.
Arguments
For
- A cluster of scheduled tanker or cargo movements in the final days could lift daily counts enough to push a 7-day average above 60.
- IMF Portwatch allows revisions to previously published data within the market timeframe, and upward revisions could retroactively raise a 7-day average to meet the threshold.
- Rapid de-escalation of regional tensions or a sudden resumption of previously curtailed exports could produce multiple high-transit days in short order.
- Seasonal or commercial scheduling quirks can sometimes cause short-lived concentration of transits that create temporary multi-day spikes.
Against
- With only days left, the seven-day averaging window mostly reflects already-published counts that market participants believe are well below 60.
- Ongoing rerouting around the Gulf, port operational limits, or security-related delays can keep transit counts suppressed for the remainder of June.
- Single-day increases cannot create a qualifying 7-day average unless the preceding six days are near the threshold, which appears unlikely given current pricing.
- Data omissions or underreporting in Portwatch reduce the likelihood that reported arrivals will hit the specified numeric threshold even if actual traffic is higher.
Key drivers
- Recent levels of daily transit calls over the past week, which determine how much uplift is needed to reach a 7-day average of 60.
- Geopolitical developments in the Gulf that can rapidly increase or decrease tanker and cargo movements through the Strait.
- Decisions by shippers to reroute or re-concentrate traffic based on insurance, security, and commercial scheduling considerations.
- Changes in oil export or tanker loading schedules that concentrate tanker transits through the Strait over a short period.
- IMF Portwatch reporting practices and any upward revisions to previously published daily transit counts made before the end date.
Risk factors
- The seven-day averaging requirement significantly raises the bar and makes late single-day spikes insufficient unless prior days are near threshold.
- Only a short time window remains to create a qualifying seven-day series, so stochastic shocks have limited time to affect the moving average.
- If IMF Portwatch omits or delays data publication for key days, the effective opportunity to reach the threshold is reduced.
- Persistent regional security incidents or sanctions-driven rerouting can keep underlying traffic depressed throughout the window.
- Market-implied price may be depressed by concentrated selling and not reflect the full range of possible data revisions or last-minute operational changes.
Scenarios
Best case
A conjunction of factors occurs: recent unpublished or close-to-threshold daily counts are higher than market assumes, IMF Portwatch issues modest upward revisions to earlier days within the allowed timeframe, and several consecutive high-transit days in the final window push the 7-day moving average to or above 60, triggering a 'Yes' resolution.
Most likely
Traffic remains below the required level and no combination of immediate surge plus allowable revisions produces a seven-day average >=60, so the market resolves to 'No', but a small chance remains for a last-minute upward revision or clustered transits that flip the average.
Worst case
No meaningful change in ship movements happens and Portwatch data remains below the required level, with no revisions sufficient to raise the seven-day average, resulting in a definitive 'No' resolution by June 30.
