Strait of Hormuz traffic returns to normal by December 31?
I assess a 72% probability that IMF Portwatch will publish a 7-day moving average of Strait of Hormuz transit calls at or above 60 for at least one date by December 31, 2026, driven by the route's centrality to global oil and goods flows but tempered by persistent geopolitical and security risks.
Analysis
Market-implied probability (Yes ~88.5%) shows strong trader conviction that traffic will return to or exceed the 60-call 7-day average threshold before year-end, but public reporting on near-term developments is sparse so that market price likely reflects risk-tolerant positions, professional hedging, and residual optimism about de-escalation rather than a consensus certainty. Historically the Strait of Hormuz is the shortest and most used maritime corridor for Gulf crude and general cargo bound for Europe and Asia, so baseline demand and shipper incentives favor a return to high transit counts as soon as security and insurance costs normalize; even a short multi-day surge in transits can lift the 7-day moving average above the 60 threshold, making the target easier to reach than a sustained long-term recovery would be. The principal countervailing factor is geopolitical and security volatility: episodic attacks on shipping, sanctions-related rerouting, insurance premium spikes, and purposeful denials of passage can depress daily calls for extended periods, and these events are inherently unpredictable; thus the path to 60 will be punctuated by potential sharp down-days that could postpone or prevent a qualifying 7-day average. Finally, the market’s resolution mechanics make qualification relatively binary and sensitive to reporting quirks — the 7-day moving average requirement is forgiving of single-day surges, revisions to previously published data within the market window count in favor of Yes, and the data provider (IMF Portwatch) methodology, reporting lags, or occasional clerical issues could affect whether a qualifying value appears and is accepted before the deadline.
Arguments
For
- The Strait of Hormuz is the shortest, most commercially efficient route for a large share of Gulf exports, creating strong incentive for traffic to resume when security allows.
- Even a transient return of tanker or cargo movements for a week can push the 7-day moving average above 60, so only short-lived normalization is required to resolve Yes.
- Major oil producers have strong economic reasons to restore export volumes quickly, including to meet contracts and avoid price spikes that hurt demand.
- Private security measures, naval escorts, and temporary convoy systems can reduce risk perception enough for shipowners to return to transit progressively.
- Market participants and insurers have adapted to past disruptions with layered risk-mitigation products that facilitate a faster resumption of routine transits.
Against
- A single sustained security incident or spike in attacks could suppress calls for multiple weeks and prevent the 7-day average from reaching 60.
- High war-risk premiums and rerouting costs may keep many commercial operators permanently avoiding the Strait, reducing baseline transit counts.
- Some cargoes and tankers have already reallocated routes or shifted to alternate loading/receiving strategies that lower demand for Hormuz transits.
- IMF Portwatch data publication timing, measurement specifics, or clerical corrections could delay or negate an apparent qualifying average.
- Geopolitical calculations may produce periodic flare-ups that intermittently push traffic down even if overall trend is recovery.
Key drivers
- Magnitude of Gulf crude and refined product exports through the Strait of Hormuz over the next six months.
- Level of geopolitical de-escalation or escalation between Iran, US forces, and regional proxies that directly affects shipping security.
- Insurance and freight-rate dynamics that determine ship operators’ willingness to transit the narrow waterway versus rerouting around Africa.
- Frequency and intensity of maritime security incidents (attacks, mines, seizures) in the Gulf of Oman and adjacent approaches.
- Commercial shipping schedules and seasonal demand cycles for oil, dry bulk and container trades that drive daily call volumes.
- IMF Portwatch reporting cadence, revisions policy, and any clerical data integrity events that could create or remove qualifying 7-day averages.
Risk factors
- A renewed period of major military escalation involving Iran or a regional state that deters traffic for multiple consecutive days.
- Sustained high war-risk and hull insurance premiums that keep commercial operators permanently rerouting via the Cape of Good Hope.
- Persistent or expanding Houthi or other proxy attacks on vessels in nearby corridors that raise systemic transit risk.
- Economic slowdown or major shifts in crude production patterns that reduce tanker transits independent of security conditions.
- IMF Portwatch reporting gaps, delayed publication, or post-period revisions that complicate or invalidate an apparent qualifying spike.
- Long-term modal shifts (e.g., new pipelines or substantially increased overland capacity) that permanently lower transit counts.
Scenarios
Best case
A clear de-escalation of regional tensions combined with reduced insurance costs and improved convoying leads to a concentrated weeklong surge in transits during Q3–Q4 2026, producing one or more 7-day averages at or above 60 and an early Yes resolution.
Most likely
Traffic gradually recovers with intermittent dips driven by episodic security incidents; the path is volatile but likely produces at least one qualifying 7-day average before December 31, 2026, resulting in Yes with higher probability than No but well short of certainty.
Worst case
A major military incident or a sustained campaign of attacks on merchant shipping forces prolonged rerouting and keeps daily calls depressed below the threshold for the remainder of 2026, producing a No resolution.
