Strait of Hormuz traffic returns to normal by end of June?
I assess about a 30% chance that IMF Portwatch will report a 7-day moving average of transit calls for the Strait of Hormuz at or above 60 on at least one day by June 30, 2026, reflecting a modest chance of rapid recovery or a short-lived surge but a greater likelihood that disruptions and time constraints will prevent a sustained rebound.
Analysis
There are fewer than four weeks remaining before the market deadline, so any return to a 7-day moving average ≥60 requires either a sustained increase in daily transit calls beginning almost immediately or a brief but very large spike in arrivals that lifts the 7-day mean. Without recent IMF Portwatch numbers in front of us, the key operational constraint is time: a 7-day moving average is slow to respond to single-day increases and requires multiple consecutive high-count days or a large cluster of arrivals within a short window to cross the threshold.
Market pricing at roughly 15% Yes implies traders expect the combination of ongoing risks and the short time horizon makes normalization unlikely; heavy volume indicates significant attention and some consensus view of low probability. My independent read is somewhat more optimistic than the market because short-term technical fixes (temporary naval convoys, enhanced escorts, or a diplomatic de‑escalation) have historically produced quick upticks in traffic, and a single week of above-normal traffic could produce the qualifying 7-day average if it arrives soon.
Key external drivers include security dynamics (escalation or de‑escalation), shipping industry risk tolerance and insurance pricing, and demand-side factors such as a sudden surge in crude or LNG liftings that route through the Strait; any of these can change volumes quickly. Countervailing structural factors—sustained rerouting through the Cape of Good Hope, higher voyage times and costs, and prolonged market caution—tend to depress transit counts and are more likely to persist unless there is a clear, credible improvement in safety or a decisive diplomatic outcome.
Finally, reporting and data issues matter: IMF Portwatch revisions, late reporting, or short-term anomalies in how arrivals are counted could create or erase qualifying days, so part of the uncertainty is administrative rather than purely physical traffic flow; however, reliance on corrected data is constrained by the market’s rules, which increases the importance of any genuine early-June rebound for meeting the criterion before the cutoff.
Arguments
For
- A rapid de-escalation or explicit security assurances could restore commercial confidence and prompt a clustered rebound in transits within days.
- Coordinated naval escort operations or international convoys have historically enabled fast, concentrated spikes in traffic through risky chokepoints.
- A sudden surge in oil or LNG exports scheduled in June could produce a short-term increase in transits sufficient to lift a 7-day average.
- Operational adjustments by shipowners to concentrate transits into narrow windows could create the necessary short-term peak.
- Data revisions or late reporting to IMF Portwatch could retroactively create a qualifying 7-day average if several high arrival days are recorded together.
Against
- If underlying security threats remain or intensify, many vessels will continue to avoid the Strait, keeping daily arrivals low.
- Higher insurance and voyage costs may permanently re-route a significant share of traffic, making rapid normalization unlikely.
- A 7-day moving average requires multiple consecutive high days, and with less than a month remaining the time buffer is small.
- Even if single-day counts spike, they may be insufficient to push the 7-day average over the 60 threshold before the deadline.
- Administrative and reporting lags or conservative counting could prevent a qualifying average from appearing even if physical traffic improves modestly.
Key drivers
- Near-term security environment in and around the Strait of Hormuz, including attacks on commercial shipping or coastal facilities.
- Diplomatic developments or military arrangements that visibly reduce the risk to commercial vessels and prompt confidence to resume normal transits.
- Insurance premiums and P&I club advisories that materially affect carrier decisions to transit or reroute.
- Seasonal and demand-side shipping patterns, particularly crude/LNG liftings or container flows that could temporarily increase traffic.
- Availability and scheduling of alternative routes and the incremental transit time and cost they impose on operators.
- Timeliness and coverage of IMF Portwatch reporting and any data revisions that could produce or eliminate qualifying 7-day averages.
Risk factors
- Renewed attacks or escalation in the wider region that keep commercial shipping away from the Strait for an extended period.
- Sustained high insurance and security costs that make rerouting via longer passages economically preferable.
- A slow return of shipowners’ confidence even after isolated de-escalation steps, delaying resumed transits.
- Insufficient time left in June for a multi-day consecutive increase to lift a 7-day moving average to 60 or higher.
- Persistent logistical or port-side bottlenecks on either side of the Strait that limit the number of reported arrivals.
- Gaps or delays in IMF Portwatch data publication or conservative counting conventions that understate actual transit activity.
Scenarios
Best case
A clear, rapid de-escalation combined with visible international naval protection and a scheduled surge in crude/LNG loadings leads to a concentrated week of arrivals that pushes the IMF Portwatch 7-day moving average to 60 or above by mid-to-late June, producing a Yes resolution.
Most likely
A patchy recovery produces occasional higher-count days or short spikes, but these are not sustained long enough to lift a 7-day moving average to 60 before June 30, so the market resolves to No while leaving the door open for a late, but insufficient, uptick.
Worst case
Hostilities or persistent attacks continue through June or escalate, shipping remains rerouted around the Cape of Good Hope or otherwise reduced, and IMF Portwatch never records a 7-day moving average reaching 60, resulting in a No resolution.
