Strait of Hormuz traffic returns to normal by end of June?
I assess a 30% probability that IMF Portwatch will show a 7-day moving average of Strait of Hormuz transit calls at or above 60 on at least one date by June 30, 2026, reflecting limited time left and a balance between economic pressure to resume normal transits and ongoing security/insurance risks.
Analysis
The immediate data situation is uncertain because the prompt indicates no recent news was fetched and I do not have the current IMF Portwatch 7-day average for the Strait; the market price (Yes 21.5%) implies traders believe normalization before June 30 is unlikely but possible. The threshold of 60 for the 7-day moving average is plausibly near what many would consider a 'normal' traffic level, so achieving it from a materially lower baseline requires a sustained and measurable uptick in daily calls over at least a week, and potentially larger increases if recent daily counts are well below 60.
From a historical and operational standpoint, shipping through Hormuz has shown the ability to rebound when overt military/security incidents subside, because rerouting around Africa is costly in time and fuel and many commercial operators prefer the shortest economic route if security and insurance permit. Key levers that can restore traffic quickly include de-escalation of regional tensions, clear protective naval operations or convoying, lower war-risk insurance premiums, and assurances from major charterers and oil companies; each of these factors can prompt companies to resume normal transits within days to weeks once the signal changes.
Against those recovery drivers are persistent and unpredictable geopolitical risks: further attacks on merchant shipping, escalatory incidents involving Iran or proxy groups, or sudden sanctions policy shifts can keep traffic depressed and discourage normalization. With less than four weeks left in the window, the time constraint meaningfully lowers the probability that a sustained 7-day window will both occur and be published, though the market can resolve as soon as a qualifying 7-day average is published on any date, so a single concentrated rebound aligned with reporting cadence could still trigger a Yes outcome. On balance I set my independent probability at 30%, higher than the market-implied 21.5% to reflect the real but limited upside from operational fixes, but still well below a coin-flip because of security volatility and the short calendar horizon.
Arguments
For
- Commercial incentives and high costs of rerouting make operators likely to resume Hormuz transits once security signals improve.
- A diplomatic de-escalation or effective multinational escort operation could restore confidence quickly and push daily counts up.
- Seasonal or cyclical increases in oil and bulk shipping demand could lift daily transit counts toward historical norms within weeks.
- Insurance rates can fall quickly if the perceived threat diminishes, removing a financial barrier to returning to the route.
- IMF Portwatch allows revisions during the market timeframe, so late corrections that raise recent counts could still produce a qualifying 7-day average.
Against
- Persistent or renewed security incidents can keep shipping owners from returning even if commercial incentives exist.
- War-risk insurance and S&P/industry advisories may remain elevated or sticky, delaying resumption of normal traffic.
- Significant rerouting to avoid the Strait imposes costs that may become entrenched, reducing the chance of a rapid return.
- With under four weeks remaining, the calendar window is tight and requires a concentrated and sustained increase in daily calls to meet the 7-day threshold.
- Absent clear, verifiable signals of improved security or official guarantees, market participants and shipowners are likely to remain cautious.
Key drivers
- Current baseline 7-day average of transit calls and the size of the gap to 60.
- Near-term regional security environment and the occurrence or absence of attacks on commercial shipping.
- War-risk insurance premiums and the willingness of shipowners to accept transits through Hormuz.
- Presence and visibility of naval escorts or multinational security initiatives in the Strait.
- Commercial demand for oil and dry-bulk shipments from Gulf exporters that typically use Hormuz.
- Economic incentives versus rerouting costs around Africa for different ship types.
- Port congestion or delays elsewhere that could push ships onto or away from the Hormuz route.
- IMF Portwatch reporting cadence, any revisions to published data, and data integrity considerations.
Risk factors
- A fresh attack on tankers or merchant vessels near Hormuz that raises perceived transit risk and reduces calls.
- Escalation between regional states or proxies that prompts insurers to raise premiums or industry advisories to avoid the Strait.
- A sustained policy or operational decision by major charterers to reroute vessels around Africa until further notice.
- Delayed or sparse IMF Portwatch reporting within the market window which could prevent a qualifying publication in time.
- Sudden changes in Gulf export volumes due to outages, sanctions, or OPEC output decisions that reduce ship movements.
- Logistical bottlenecks at Gulf terminals or in adjacent chokepoints that suppress short-term transit counts.
- Negative media coverage that amplifies perceived risk and prompts voluntary avoidance by shipowners.
- Revisions to reported daily calls after the qualifying date that do not help trigger a qualifying 7-day average within the timeframe.
Scenarios
Best case
A rapid sequence of positive events — a de-escalatory diplomatic breakthrough, a publicized multinational escort program, and a prompt fall in war-risk insurance — leads to a sharp, sustained increase in daily transit calls that pushes a 7-day moving average above 60 within two to three weeks, producing a Yes resolution.
Most likely
Security remains uneasy but without a decisive positive turn, transits recover slowly and irregularly so that short-lived upticks do not produce a sustained 7-day average at or above 60 before June 30, resulting in a No outcome, though a single well-timed improvement could still produce a Yes with modest probability.
Worst case
A new attack or escalation occurs, insurers and charterers maintain avoidance of the Strait, daily transit calls stay depressed or fall further, IMF Portwatch publishes no qualifying 7-day average by June 30, and the market resolves No with high confidence.
