Strait of Hormuz traffic returns to normal by July 7?
I assess a low but meaningfully higher-than-market chance that IMF Portwatch will report a 7-day moving average of arrivals in the Strait of Hormuz of at least 60 on some date by July 7, 2026, driven by the short time window and operational constraints; my probability is 15%.
Analysis
The market-implied probability is very low (Yes: 5.5%), reflecting trader judgment that a sustained spike in reported arrivals sufficient to push a 7-day moving average to 60 inside a very short remaining window is unlikely. The instrument’s resolution rule requires the 7-day moving average to reach or exceed 60 for any reported date up to July 7, which means even if daily counts briefly rise, they must be sustained long enough to lift the week-long average — a demanding condition with limited days left in the event window.
Historically, traffic through the Strait of Hormuz has been subject to significant volatility from geopolitical events, insurance and routing decisions, and seasonal trade flows; normal (pre-disruption) volumes frequently produced multi-week stretches of high daily arrivals, but disruptions can and have reduced those numbers materially. Without up-to-date Portwatch figures in front of us, the key empirical question is how far the current 7-day average sits below 60: if it is only a handful of arrivals short, a rapid operational normalization, convoying, or data revision could push it over the threshold, whereas a large deficit would make recovery before July 7 effectively impossible.
Market structure and time pressure favor low odds: only a short window remains for seven consecutive days (or otherwise sustained days) to lift a moving average; however, the market price at 5.5% likely discounts scenarios such as immediate diplomatic de-escalation, rapid insurance-market responses, or concentrated shipments scheduled in the coming week. Given the balance of plausible rapid-recovery paths and the strict averaging requirement, I place a modestly higher independent probability (15%) than the market to allow for tail events (fast normalization or reporting revisions) while acknowledging the high barriers to success in the next 9–10 days.
Arguments
For
- If the current 7-day average is only marginally below 60, a concentrated increase in scheduled transits over the next week could push the average above the threshold.
- A rapid diplomatic de-escalation or a temporary ceasefire could prompt immediate resumption of previously deferred voyages through the Strait.
- Improved insurance terms or naval escort arrangements announced at short notice could incentivize a quick return of commercial traffic.
- Portwatch data revisions or the inclusion/correction of previously unreported arrivals could raise the reported 7-day average retrospectively to meet the threshold.
Against
- The 7-day moving average requirement is structurally demanding, needing sustained higher daily arrivals rather than a single-day spike.
- If the current average is substantially below 60, there simply isn't enough time left to bring a week-long average up to that level by July 7.
- Persistent or renewed security threats will keep operators routing around the Strait or delaying voyages, suppressing arrivals.
- Even with temporary risk reductions, many operators prefer route certainty and may not immediately revert from alternative routings or pipeline use.
Key drivers
- Current level of the 7-day moving average: the closer it already is to 60, the easier it is to cross the threshold within the remaining window.
- Short-term scheduling and routing decisions by tanker and cargo operators that could concentrate additional transits through Hormuz quickly.
- Geopolitical developments, especially any rapid de-escalation between Iran and regional or Western powers that would reduce perceived transit risk.
- Insurance market responses and availability of acceptable war-risk premiums, which directly influence operators’ willingness to use the route.
- Naval escort operations and coalition security measures that can restore commercial confidence and encourage returns to the route.
- Data publication and revision practices at IMF Portwatch, since upward revisions or late corrections could create qualifying dates.
Risk factors
- A new or renewed security incident (attacks on ships, seizures, or strikes) that suppresses transits or deters operators.
- Sustained high war-risk insurance premiums that keep owners and charterers routing around alternatives rather than through the Strait.
- Prolonged diplomatic stalemate that maintains the elevated risk environment and prevents quick normalization of commercial traffic.
- Major shipping companies or charterers deciding to keep vessels on alternative routes for operational certainty even if short-term risk eases.
- Adverse weather or navigational restrictions in the region that temporarily reduce reported arrivals.
- Delays, gaps, or conservative reporting practices at IMF Portwatch that postpone publication or keep reported counts lower.
Scenarios
Best case
A rapid de-escalation occurs, large numbers of ships scheduled for the region are routed back through Hormuz, and/or Portwatch revises upward prior days’ counts, producing a 7-day moving average at or above 60 for at least one published date before July 7.
Most likely
Traffic rises modestly but not enough to lift the 7-day average to 60 within the remaining short window, so the market resolves to No, though there remains a small chance of a late surge or a data revision creating a qualifying date.
Worst case
Security incidents, persistent high insurance costs, or operator conservatism keep transit counts depressed and published Portwatch data never reaches a 7-day moving average of 60 during the event window, resolving the market to No.
