Strait of Hormuz traffic returns to normal by end of June?
I assess a low probability that IMF Portwatch will report a 7-day moving average of transit calls for the Strait of Hormuz at or above 60 on any date through June 30, 2026, primarily because the 7-day average requirement and the short time window make a sustained rebound unlikely absent a clear and rapid surge in traffic.
Analysis
Time is the dominant constraint: with only about ten days left until the June 30 cutoff, any qualifying outcome requires a sustained increase in daily transit calls sufficient to lift a 7-day moving average to 60 within a short window, which is a high bar compared with a single-day spike. If the current 7-day moving average is materially below 60, recovering to 60 requires multiple consecutive days of markedly higher than normal calls, and those days must already have occurred or occur immediately to affect the published moving average in time.
Structural factors of shipping flows work against very rapid reversals: ship movements, port scheduling, and commercial routing decisions typically change over weeks rather than overnight, so systemic constraints (port congestion, rerouting around conflict zones, crew changes, chartering lead times) reduce the chance of a one-week surge sufficient to push a 7-day MA past the threshold. Conversely, discrete events (an abrupt de-escalation of regional hostilities, a sudden reopening of chartering corridors, or an operational fix that clears backlog) could cause a fast uptick in transits, but such events are hard to forecast and would need to occur immediately to matter.
Market-implied probabilities are currently very low, which suggests informed traders are valuing either a still-substantially-below-threshold 7-day average or a high likelihood that any upticks will be insufficient or too late; given the absence of fresh confirmatory news in the provided context and the tight deadline, the market signal is a sensible anchor. However, absent direct access to the current Portwatch numbers in this prompt, my assessment allows for limited upside relative to the market-implied price because short-term operational recoveries or reporting revisions could still produce a qualifying 7-day average in a narrow window.
Data and resolution rules slightly raise the chance relative to a single-day measure because revisions to earlier published points during the market timeframe are considered, meaning post-publication corrections could retroactively create a qualifying 7-day average; nevertheless, the rules also limit the period for corrections and exclude revisions after June 30, which constrains how much late adjustments can change the outcome and keeps the overall probability low.
Arguments
For
- If the current 7-day moving average is only slightly below 60, a concentrated surge of arrivals over the next several days could push the average above 60.
- Operational clearances or reopening of previously disrupted ports and anchorages could release a backlog and temporarily spike daily transit calls.
- In-period revisions by IMF Portwatch to previously published counts could retroactively create a qualifying 7-day average if errors are corrected before the deadline.
Against
- The 7-day moving average requirement demands sustained elevated traffic, so isolated single-day increases are insufficient to achieve a qualifying value.
- Only about ten days remain, making it unlikely that commercial and scheduling processes can produce a sustained multi-day rebound in time.
- Market prices already imply low probability, reflecting that traders likely have information or expectations of persistent subdued flows or late timing.
Key drivers
- Current level of the 7-day moving average relative to the 60 threshold, since small gaps are easier to close than large ones.
- Timing and magnitude of any immediate surge in daily transit calls over consecutive days, because a 7-day average requires sustained increases.
- Operational and commercial shipping dynamics like schedule slack, port congestion, and rerouting times, which determine how quickly traffic can rise.
- Geopolitical developments in the Gulf region that could either rapidly restore confidence and reopen traffic or prolong disruptions.
- IMF Portwatch reporting cadence and any in-period data revisions, because corrections could create or remove qualifying 7-day averages.
Risk factors
- Lack of current published Portwatch data in this prompt increases uncertainty about the starting 7-day average level.
- A single strong surge in arrivals that is not sustained over seven days will not lift the 7-day moving average to the threshold.
- Late corrections to published data after June 30 are excluded, limiting the impact of post-period adjustments on resolution.
- Unanticipated large-scale commercial decisions (e.g., mass rerouting or sudden chartering spikes) could push the outcome toward Yes despite low prior odds.
- Geopolitical volatility could reverse quickly and either create a qualifying week or further suppress traffic, adding outcome volatility.
Scenarios
Best case
A rapid and sustained operational recovery or immediate resolution of a regional disruption triggers consecutive days of higher arrivals, lifting the 7-day moving average to or above 60 before June 30, possibly aided by in-period data corrections that favor higher counts.
Most likely
Some increase in traffic occurs as conditions normalize, but either the increases are too small or too late in the window to produce a 7-day moving average of 60 or higher, so the market resolves to No.
Worst case
Traffic remains subdued or only shows brief spikes that do not persist for a full week, no qualifying 7-day average is published by June 30, and the market resolves to No with minimal chance of retroactive changes given the cutoff rules.
