Strait of Hormuz traffic returns to normal by end of June?
I assess a 30% probability that IMF Portwatch will publish a 7-day moving average of Strait of Hormuz transit calls at or above 60 on any date through June 30, 2026, reflecting a modest chance of rapid recovery but substantial downside risk from persistent security and commercial friction.
Analysis
The market price (Yes ~17.5%) signals low confidence that a sustained recovery to a 7-day moving average of 60 will occur before June 30, and my independent view is somewhat higher but still cautious at 30%. Reaching a 7-day moving average of 60 requires not just a single busy day but a cluster of elevated daily arrivals within the remaining two-plus weeks, which compresses the time available for operational recovery measures to take effect.
Security and geopolitical factors are the dominant determinants of short-term traffic through Hormuz: successful de-escalation, effective international naval escorts, or clear reduction in attack activity can rapidly restore commercial willingness to transit, whereas any uptick in attacks, mines, or near-miss incidents will prolong rerouting and insurance-driven avoidance. Commercial dynamics matter too—insurers, charterers, and operators respond quickly to perceived risk, and changes in war-risk premiums or reflagging/escort arrangements can either accelerate or retard a return to normal volumes.
Data and measurement considerations create an asymmetric pathway to a Yes outcome: a bona fide surge in arrivals sustained over a week is one route, but so is an anomalous reporting spike or a revision to published daily counts that lifts the 7-day average above 60; IMF Portwatch revisions within the market window count toward resolution. Given the short window, I judge the combination of operational inertia, remaining risk aversion in the market, and the need for a sustained multi-day rise makes the chance of hitting the 60 threshold modest but non-negligible.
Arguments
For
- Major GCC exporters have strong economic incentives to resume and schedule tanker transits, which can quickly push arrivals higher if security stabilizes.
- International naval escorts and coordinated convoy schemes can materially reduce perceived risk and encourage owners to transit the Strait again.
- Commercial actors have historically resumed normal routing quickly after risk mitigation measures are visible, enabling a short-term rebound.
- A concentrated surge in ship movements or a favorable sequence of daily counts during the remaining window could lift the 7-day average above 60.
- IMF Portwatch allows revisions during the market window, so retroactive upward adjustments to reported counts could produce a qualifying 7-day average.
Against
- Ongoing or renewed security incidents will keep many owners preferring longer, safer routes or delaying sailings, suppressing arrivals.
- High war-risk insurance costs and charterer reluctance can create a multi-week lag before vessels return to pre-crisis routing.
- Operational inertia and vessel repositioning constraints mean even willing shippers may be unable to generate enough transits in the short window.
- Exporters may prioritize strategic inventory or pipeline routing over immediate increases in tanker transits, reducing throughput.
- If IMF Portwatch underreports certain categories or has reporting delays, published numbers may remain below the threshold despite increased activity.
- Weather, maintenance, or scheduled dry-docking across a cluster of vessels could coincidentally depress arrivals during the critical measurement period.
Key drivers
- Level and visibility of international naval escorts and allied maritime security patrols in and near the Strait.
- Frequency and effectiveness of hostile incidents (missile, drone, mine, or small-boat attacks) targeting commercial shipping in the Gulf or adjacent waters.
- Commercial insurance conditions, specifically war-risk premiums and hull cover availability for transits through the Strait.
- Production and export scheduling decisions by major Gulf producers that increase or decrease tanker traffic volume.
- Operational readiness and redeployment speed of tankers and commercial vessels currently routed away from the Strait.
- IMF Portwatch reporting cadence, revisions, and any data integrity or coverage changes that could alter published daily transit counts.
Risk factors
- A new or intensified wave of attacks on vessels or port infrastructure that sustains elevated risk perceptions and rerouting.
- Persistently elevated war-risk premiums that keep many shipowners from accepting Strait transits for weeks.
- Delays in implementing or scaling up convoy/escort systems that leave operators unwilling to resume normal routes.
- Commercial backlog or port congestion elsewhere that prevents ships from returning to pre-disruption schedules quickly.
- IMF Portwatch reporting gaps or conservative coverage that undercounts actual transits and keeps the published average low.
- Strategic production cuts or maintenance cycles among exporters that reduce tanker movements regardless of security trends.
Scenarios
Best case
Rapid de-escalation combined with a visible increase in allied naval escorts and lowered insurance premiums triggers a concentrated rise in transits that sustains a 7-day moving average at or above 60 before June 30, possibly aided by favorable data revisions.
Most likely
Security concerns remain elevated but contained, producing sporadic increases in transit calls that fall short of a sustained 7-day average of 60 before June 30, leading to a No resolution while leaving open the possibility of normalization later in Q3.
Worst case
Hostile incidents or credible threats escalate or continue unabated, prompting extended rerouting and avoidance by commercial shipping and keeping IMF Portwatch 7-day averages well below 60 through the end of June.
