Strait of Hormuz traffic returns to normal by July 15?
I assess a modest but below-even probability (35%) that IMF Portwatch will publish a 7-day moving average of Strait of Hormuz transit calls at or above 60 on any date through July 15, 2026, because the window is short and geopolitical uncertainty still suppresses routine peak traffic despite occasional rebounds.
Analysis
Geopolitical and operational risks remain the dominant external factors over the next three weeks: any new incidents, sanctions, or insurance-market shocks could quickly lower transits, while a de-escalation, temporary ceasefire in nearby theaters, or a sudden pickup in crude exports could lift daily calls enough to push a week-long average above 60. Finally, reporting and data issues (publication lags, revisions) add non-negligible technical risk—IMF Portwatch revisions within the window can qualify and could retroactively create a qualifying 7-day average, which slightly increases the probability relative to looking only at raw daily counts.
Arguments
For
- A modest de-escalation in regional tensions or a localized ceasefire would quickly restore commercial confidence and increase transit calls.
- Resumption or ramp-up of crude export programs from Gulf producers could add tanker arrivals and push weekly averages upward.
- Seasonal increases in dry-bulk and container activity in early summer could raise non-tanker transit counts and contribute to the average.
- IMF Portwatch revisions within the market window could retroactively create a qualifying 7-day average even if initial releases do not show it.
Against
- Persistent or renewed security incidents would keep shippers avoiding the Strait and prolong below-normal transit levels.
- High insurance costs and war-risk premiums could maintain a financial disincentive for using the Gulf route compared with alternatives.
- If current 7-day averages are materially below 60, the remaining time is likely insufficient for a sustained recovery to reach the threshold.
- Commercial and logistical inertia means operators often delay route changes, so short-notice improvements in conditions may not immediately translate into higher arrivals.
Key drivers
- Current level of the 7-day moving average at the time of assessment, since proximity to 60 determines required incremental change.
- Short-term changes in oil export volumes from Gulf terminals, which directly influence tanker calls through Hormuz.
- Maritime security conditions and incidence of attacks/escorts, which affect ship routing and willingness to transit the Strait.
- Insurance and freight-rate economics that determine whether ships choose the shorter Gulf route or longer alternatives.
- Seasonal commercial shipping patterns and peak demand cycles for dry bulk and container trades that may raise non-tanker transit counts.
- Data publication timing and revisions by IMF Portwatch, which can create or retroactively reveal qualifying 7-day averages.
Risk factors
- A new spike in regional hostilities that causes rerouting or suspension of transits would materially lower the chance of Yes.
- Sustained elevated insurance premiums and war-risk surcharges that keep commercial traffic off Hormuz would suppress arrivals.
- Incomplete or delayed publication of IMF Portwatch data within the window could defer resolution and add uncertainty.
- If the current 7-day average is substantially below 60, the short calendar window makes large enough increases statistically unlikely.
- A dominant share of traffic being tankers means that changes in crude export policy or refinery turnarounds can rapidly affect counts.
- A temporary surge in non-reporting vessels or classification differences could mask real increases in traffic and prevent qualification.
Scenarios
Best case
A rapid and sustained improvement in regional security combined with a clear uptick in Gulf export loadings triggers a run of daily arrivals that lift the 7-day moving average above 60 within the next two weeks, possibly aided by a favorable IMF Portwatch revision.
Most likely
Traffic fluctuates but does not sustain a long-enough increase to push the 7-day average to 60, so occasional high-days occur but the weekly average stays below the threshold and the market resolves to No.
Worst case
A new episode of violence, a major attack on shipping, or a sudden increase in insurance costs causes continued suppression of transits and the 7-day average remains below 60 through July 15, resulting in a No resolution.

Starbucks total global stores in 2026
AI65%MKT9%Edge+56Hidden GemI assess a better-than-even chance that Starbucks will report more than 41,800 global stores in 2026 — the company is already near that threshold and management growth targets make reaching +800 net stores plausible despite closures and remodeling.

Will Trump take back the Panama Canal?
AI3%MKT32%Edge-29HypedIndependent assessment: ~3% probability that Donald Trump will successfully "take back" the Panama Canal during his term (through force, coercive seizure, or formal transfer of sovereignty). Forcible seizure is effectively zero; the small residual probability reflects low‑likelihood diplomatic/coercive scenarios or semantic/contractual reinterpretations of "take back."

Who will Trump pardon?
AI15%MKT44%Edge-29HypedI assess a 15% chance that Barron Trump will receive a presidential pardon before Jan 21, 2029 — low because there is no current legal exposure and pardoning a family member carries heavy political cost, but nonzero because presidents can and sometimes do issue preemptive clemency and Trump has shown a willingness to use pardons broadly.
