Strait of Hormuz traffic returns to normal by December 31?
I assess a 70% probability that IMF Portwatch will report a 7-day moving average of transit calls through the Strait of Hormuz equal to or above 60 on at least one date before December 31, 2026, given the long time horizon, high market-implied probability, and the chokepoint nature of the waterway.
Analysis
The market-implied probability (Yes ~73.5%) and substantial event volume indicate active, informed trading and a consensus that a return to a level at or above 60 is likely within the remaining months of 2026. Because the market requires only a single date with a 7-day moving average at or above 60, the hurdle is less strict than sustained normalization, and that asymmetry increases the chance of resolution to Yes compared with requiring a long-term sustained rate.
Operational and commercial incentives favor traffic returning to typical levels: the Strait of Hormuz is a vital and constrained bottleneck for Persian Gulf exports with few practical large-scale alternatives, so shipping tends to resume quickly after short disruptions when security conditions permit and exporters resume flows. Global oil and bulk trade cycles, charter rates, and production decisions (including OPEC+ actions) will influence tanker and bulk transits, and modest recoveries or seasonal peaks in demand could push short-term averages above the threshold.
Geopolitical and security risks are the main counterweight; persistent or escalated regional conflict, a major attack on shipping, or a credible threat of closure would depress transits and could prevent any 7-day average from reaching 60 for the remainder of the year. In addition, reporting and measurement considerations matter: IMF Portwatch coverage and any revisions to published data could affect whether a qualifying 7-day moving average appears even if physical traffic is near the threshold.
Balancing these factors, the long time window (roughly seven months from today) and the fact that only a single qualifying date is required push my assessment toward Yes, but nontrivial tail risks from sustained geopolitical disruption or significant, prolonged demand weakness justify discounting some of the market-implied probability.
Arguments
For
- The market only requires a single date with a 7-day average at or above 60, so short-term rebounds or seasonal peaks can produce a qualifying value.
- The Strait of Hormuz is a structural chokepoint with few large-scale alternatives, which tends to restore traffic quickly once immediate threats subside.
- Active market pricing and high event volume suggest that traders have already priced in many adverse scenarios, leaving upside for a normalizing outturn.
- Commercial and state incentives to export hydrocarbons and commodities will push operators to resume or maintain transits when risk is manageable.
Against
- A significant, sustained escalation of regional hostilities could suppress transit counts well below typical levels for an extended period.
- If producers curtail shipments or sanctions materially reduce tanker movements, aggregate transit calls may never reach the threshold.
- Repeated security incidents or insurance-related cost increases could alter routing and frequency enough to prevent any 7-day average from hitting 60.
- Data-reporting anomalies or delayed corrections at the resolution source could prevent a qualifying average from being recorded even if physical traffic trends upward.
Key drivers
- The frequency and severity of regional military incidents or attacks that directly deter or disrupt commercial transits through the Strait of Hormuz.
- Export volumes from Gulf producers and tanker loading activity tied to oil production decisions and sanctions regimes.
- Global shipping demand cycles and charter rates that influence fleet deployment to Gulf-to-world routes.
- IMF Portwatch data coverage, reporting lags, and any post-publication revisions that could create or erase qualifying 7-day averages.
- Shipping companies' routing and risk-management choices, including whether firms resume normal transit patterns after short-term incidents.
Risk factors
- A major or prolonged regional escalation that makes transits unsafe or prompts operators to reroute or idle vessels for extended periods.
- Sustained reductions in Gulf exports due to sanctions, production cuts, or long-term shifts in demand that keep raw transit counts low.
- Repeated minor incidents that, while not closing the waterway, cumulatively depress throughput below the threshold.
- Systemic reporting gaps, outages, or data integrity issues at IMF Portwatch that could delay or obscure qualifying averages.
Scenarios
Best case
Security tensions remain limited and episodic, maritime insurance and company risk tolerance return to normal, and a seasonal or demand-driven surge in tanker and cargo movements produces at least one 7-day moving average at or above 60 well before year-end.
Most likely
Intermittent security incidents continue but are not sustained, exporters and shipping firms gradually resume or maintain flows, and a brief period of elevated activity—driven by demand seasonality or production adjustments—produces a single qualifying 7-day average before December 31, 2026.
Worst case
A major regional military escalation or a series of sustained attacks forces prolonged avoidance or closure of the Strait, Gulf exports remain depressed, and IMF Portwatch never records a 7-day moving average reaching 60 during the market window.
