Strait of Hormuz traffic returns to normal by December 31?
I assess a 78% probability that the Strait of Hormuz will see a 7-day moving average of transit calls at or above 60 at least once by December 31, 2026, because baseline traffic levels and commercial incentives favor a return to pre-disruption volumes absent sustained major escalation, while geopolitical flare-ups and insurance/routing shifts remain the primary downside risks.
Analysis
Market-implied odds (Yes ~82%) and substantial trading volume indicate strong market conviction that traffic will reach the 60 threshold before year-end, and absent contrary real-time data I treat the market price as informative but not determinative. The resolution condition — a 7-day moving average at or above 60 for any date through December 31, 2026 — is easier to meet than a requirement for sustained months of recovery because it only requires a short multi-day uptick rather than permanent normalization.
From a structural-economic perspective, incentives favor vessels using the Strait when it is safe: shorter routes, lower voyage time and fuel cost compared with long detours around Africa, and demand for oil and bulk commodities that transit Gulf exporters are likely to sustain or increase through 2026 if global growth remains around trend; these factors make occasional 7-day windows above the 60 threshold likely. Protective measures taken by navies, convoying, and higher war-risk premiums historically have shortened and contained disruptions rather than permanently diverting most traffic, which supports a relatively high probability that normal transit rates will recur at times during the year.
Geopolitical and security risk is the principal offsetting force: renewed, sustained attacks on commercial shipping, a significant regional escalation involving state-on-state naval action, or lengthy, widespread insurance blacklisting could push shippers to avoid the Strait for extended periods and suppress transit counts below the threshold. Such scenarios remain possible through December 2026 given the region’s volatility, and market participants appear to be implicitly pricing a moderate probability of continued calm.
Data and measurement considerations further shape my view: the 7-day moving average requirement smooths single-day spikes and requires multi-day elevated flows, so short anomalies are less likely to qualify unless there is a genuine surge or recovery; conversely, revisions to IMF Portwatch data within the period can retroactively validate qualifying dates, which slightly increases the chance of a Yes resolution. Balancing structural drivers, security tail risks, and the smoothing/validation features of the contract, a probability modestly below the current market price best reflects my independent assessment.
Arguments
For
- Argument for Yes: Short-route commercial economics and time savings make returning to normal Strait transits likely whenever security conditions are judged acceptable by shippers.
- Argument for Yes: International naval escorts, improved maritime security measures, and ad hoc convoying historically reduce effective risk and support resumed traffic.
- Argument for Yes: Global energy and commodity demand in 2026 is likely to sustain or increase tanker and bulk movements from Gulf producers, boosting transit counts.
- Argument for Yes: The contract requires only a 7-day moving average above 60, so transient but genuine recoveries or export spikes can satisfy the threshold.
- Argument for Yes: Market participants appear confident (Yes ~82%), suggesting informed traders expect no long-term closure or mass rerouting through year-end.
- Argument for Yes: Data revision rules allow qualifying values to persist even if later adjustments are made within the market window, modestly raising the chance of a Yes outcome.
Against
- Argument against Yes: A renewed, sustained campaign of attacks on commercial shipping or direct state-to-state naval conflict could keep traffic suppressed below 60 for months.
- Argument against Yes: Elevated war-risk insurance and sanctions effects could make rerouting economically preferable for many shippers, reducing Strait calls.
- Argument against Yes: If Gulf producers curtail exports due to production decisions or sanctions, tanker volumes — a large component of transit calls — could fall materially.
- Argument against Yes: Structural shifts in routing or longer-term changes in trading patterns could lower baseline transit counts so that occasional peaks no longer reach 60.
- Argument against Yes: The 7-day moving average requirement filters out single-day spikes, so brief isolated increases in traffic may not suffice to meet the contract condition.
- Argument against Yes: Uncertainty in data publishing or unforeseen changes in IMF Portwatch reporting cadence could create measurement risk and complicate realization of a qualifying value.
Key drivers
- Commercial incentives for shortest routes favor resumption of Strait transits when perceived security risk is moderate or mitigated.
- Global oil and commodity demand trends that increase Gulf export volumes would raise routine transit counts through the Strait.
- Continued international naval presence and convoy systems lower the practical risk for commercial shippers and encourage transit resumption.
- Insurance premiums and war-risk surcharges can materially raise costs and induce rerouting, reducing daily calls through the Strait.
- A single short-lived uptick in exports or fleet movements can produce a 7-day moving average above 60 because the contract requires only a brief sustained rise.
- IMF Portwatch data revisions within the contract window can retroactively validate a qualifying 7-day average and thus affect resolution probabilities.
Risk factors
- A major regional military escalation or a campaign of attacks on commercial shipping could depress transit counts for an extended period.
- Prolonged or widespread war-risk exclusion from insurers could force re-routing around Africa and permanently lower Strait transits during the market window.
- Sustained reductions in Gulf oil exports due to production cuts or sanctions would reduce tanker traffic and overall daily arrivals.
- Significant disruptions to port operations or regional logistics chains (e.g., major port strikes or regional infrastructure damage) could suppress calls.
- Long-term shifts in supply chains that reduce reliance on Gulf exports would lower baseline transit levels independent of short-term security dynamics.
- Delayed or incomplete IMF Portwatch data publication or atypical revisions could create ambiguity and change the effective chance of a qualifying 7-day average being recorded.
Scenarios
Best case
A best-case scenario sees a stable security environment, continued naval protection, and a pickup in Gulf exports that produce multiple multi-day upticks in arrivals, easily pushing the IMF Portwatch 7-day moving average above 60 well before year-end and validating a Yes outcome.
Most likely
The most likely scenario is intermittent security incidents contained by international responses combined with steady commercial demand that produces occasional brief 7-day windows of elevated transit activity, yielding at least one qualifying 7-day moving average above 60 and a Yes resolution, though not without intermittent volatility and downside spikes in risk sentiment.
Worst case
A worst-case scenario involves a sustained regional escalation with repeated attacks on commercial shipping and broad insurer exodus that forces long-term rerouting around Africa, keeping the 7-day moving average below 60 through December 31, 2026 and resulting in a No outcome.
