Strait of Hormuz traffic returns to normal by July 31?
I assess a 43% 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 on or before July 31, 2026, reflecting a modest chance of recovery given remaining time but significant geopolitical and demand-side downside risks.
Analysis
There are 39 days left in the window through July 31, 2026, which is a relatively short but nontrivial period for the 7‑day moving average to climb above 60 if daily transit counts increase sharply and persistently; however, because the metric is a 7‑day average, any single spike in one or two days will be diluted and a sustained week of higher-than-normal traffic will be required to produce a qualifying published value. We do not have the current 7‑day average value from IMF Portwatch in the supplied context, so I treat the current market price as a market-implied view and adjust based on plausible pathways for increased or suppressed traffic over the coming weeks.
Historically, Strait of Hormuz daily transit calls are sensitive to oil tanker flows and regional commercial shipping patterns, so returning to a threshold of 60 7‑day average implies a near-normal mix of tankers, bulk, container, and ro-ro traffic sustained across at least a week; if recent weeks show meaningful suppression due to security worries, reaching the threshold will require several consecutive high-volume days to overcome the deficit. Market sentiment (Yes at ~40%) suggests traders see recovery as possible but not probable; I lean slightly higher than the market because the calendar window still allows for rebounds from logistics normalization, scheduled loadings, or temporary policy changes that restore transits quickly.
The dominant external uncertainties are geopolitical: an episodic escalation (attacks on merchant shipping, naval incidents, or sudden sanctions affecting one or more Gulf exporters) would likely depress transits and make the threshold unreachable, while de‑escalation, resumption of previously curtailed exports, or rerouting decisions that favor short Gulf passages could lift daily transits into the qualifying range. Other relevant external factors include seasonal operational schedules at Persian Gulf ports, changes in crude export volumes from major Gulf producers, and any reported methodological changes or revisions from IMF Portwatch; data revisions within the market window can retroactively create qualifying 7‑day averages, so published corrections are a nontrivial pathway to a Yes outcome.
Arguments
For
- There is still over five weeks remaining, enough time for a sustained week of elevated daily transits to push the 7‑day moving average above 60 if commercial activity rebounds.
- If recent low counts were driven by short-lived security incidents or temporary port disruptions, normal scheduling and insurance adjustments can restore traffic quickly.
- Tankers constitute a large share of Strait traffic so even modest increases in crude export loadings or release of previously blocked cargoes can materially raise daily counts.
- IMF Portwatch allows revisions within the market window, so corrected or revised upward daily counts could create a qualifying 7‑day average even if initially missed.
Against
- The 7‑day moving average requirement demands a sustained week of higher-than-normal activity, so isolated high-count days are insufficient to produce a qualifying published value.
- Ongoing regional geopolitical friction or fresh incidents could keep commercial operators and insurers risk-averse, depressing transits below the threshold.
- If non-tanker cargo flows (containers, bulk, ro-ro) remain weak due to global demand softness or rerouting choices, total transit calls may struggle to reach the 60 average even if tanker counts improve.
- A major export policy change or sanction that reduces shipments from a Gulf exporter would lower daily calls and likely prevent the average from reaching the threshold within the remaining window.
Key drivers
- Immediate trajectory of crude oil export loadings from Saudi Arabia, UAE, Iraq and Iran over the next five weeks, which directly affects tanker transit counts.
- Frequency and severity of any security incidents (e.g., vessel attacks, seizures, or naval confrontations) that deter commercial transits through the Strait.
- Commercial decisions by major carriers and charterers on routing, including whether vessels reroute around alternatives or return to the shorter Hormuz passage.
- Operational uptime and scheduling at major Gulf load ports and transshipment hubs that determine the cadence of arrivals through the Strait.
- Insurance and war-risk premium levels which influence commercial willingness to transit the Strait versus longer alternative routes.
- IMF Portwatch data publication timing and any intra-window revisions which can create or remove qualifying 7‑day averages.
Risk factors
- A sudden high-profile attack or escalation in the Persian Gulf that triggers prolonged avoidance of the Strait by commercial shippers.
- A coordinated export cut or production disruption from one or more Gulf producers that reduces tanker calls below historically normal levels.
- Extended operational problems at major Gulf terminals, such as strikes, port maintenance or local weather-related closures that suppress transit counts.
- Persistent rerouting of traffic to alternative corridors for commercial or insurance reasons, keeping daily counts depressed.
- Delayed or inconsistent reporting by IMF Portwatch or discoverable data integrity issues that complicate timely qualification of a 7‑day average.
- Global demand shock (e.g., sudden downturn in industrial activity or cargo demand) that reduces non-tanker transits through the Strait.
Scenarios
Best case
A rapid but plausible best case is that scheduled crude shipments and bulk movements from multiple Gulf exporters rise in late June/early July while no new security incidents occur, producing seven consecutive days of daily transit counts well above 60 and yielding an IMF Portwatch 7‑day average at or above the threshold; an intra-window data revision could further improve the chance of a published qualifying value.
Most likely
The most likely scenario is modest variability in weekly transit counts with occasional spikes but insufficient sustained elevation to push the 7‑day average above 60, resulting in no qualifying IMF Portwatch publication before July 31, although a surprise operational uptick or favorable revision leaves a meaningful minority chance of a Yes outcome.
Worst case
A worst case is that one or more significant security events or an export curtailment occur, causing carriers to avoid the Strait for several weeks and keeping daily calls depressed so that the 7‑day moving average never reaches 60 before July 31, and potential data publication or revision timing does not produce a qualifying value.
