Strait of Hormuz traffic returns to normal by June 15?
I assess a low probability (10%) that IMF Portwatch will publish a 7-day moving average of Strait of Hormuz transit calls >= 60 on any date through June 15, 2026, because the short time window and need for a sustained surge in daily transits make a rebound unlikely, though a rapid de-escalation or sudden rerouting back through Hormuz could produce an outsized jump.
Analysis
Timing and metric constraints strongly limit upside: as of June 5 there are only ten calendar days before the June 15 cutoff, and the market resolves if any single published 7-day moving average meets or exceeds 60, which requires roughly a week of daily transit counts high enough to push the moving average to that level; if the present 7-day average is substantially below 60, there is little time for recovery. The market's design (first qualifying published point wins, revisions within the window allowed, but not after the final date) slightly raises the theoretical chance that a short spell of heavy traffic or a data revision could trigger resolution, but such outcomes remain contingent and uncommon.
Arguments
For
- A sudden diplomatic de-escalation involving Gulf powers and guarantied safe passage could induce shipowners to route vessels back through Hormuz within days.
- Rapid normalization of insurance and war-risk premiums would lower the cost of transiting the Strait and incentivize immediate rerouting of tankers and commercial ships.
- A short-term surge in tanker movements driven by an unexpected oil supply/distribution shock could temporarily raise daily transit counts above the threshold.
- Coordinated multinational naval escorts announced and deployed quickly could restore commercial confidence and drive a rapid return to normal transit levels.
Against
- Commercial rerouting, contractual obligations, and insurance arrangements typically change on weeks-to-months timescales, making an immediate seven-day rebound unlikely.
- If the present 7-day average is materially below 60, there is insufficient time remaining for natural variation alone to push the average high enough by June 15.
- Persistent or recurrent security threats would keep traffic depressed and deter short-notice redeployment of vessels through the Strait.
- Data publication timing and the requirement for a bona fide 7-day average mean that even a single-day spike in traffic is insufficient without sustained elevated counts over multiple days.
Key drivers
- Current 7-day moving average level relative to 60 (if already near 60, small uptick could push it over).
- Geopolitical tensions in the Gulf, including any rapid de-escalation or flare-ups that immediately affect ship route choices.
- Commercial insurance and war-risk premiums that determine whether shippers will resume routing through the Strait.
- Oil market dynamics and chartering decisions that can cause sudden redeployment of tankers through Hormuz.
- Portwatch data publication cadence and any permitted intra-window revisions that could retroactively qualify data.
- Naval escort availability and multinational security measures that could quickly restore confidence in the corridor.
- Seasonal shipping patterns and scheduled commercial cycles that might produce short-term spikes in transits.
Risk factors
- Persistent security incidents or credible threats that keep commercial traffic routed away from Hormuz.
- Sustained insurance/warrisk cost differentials that continue to make alternative routes economically preferable.
- Regulatory or sanction-related impediments that restrict the flow of certain vessel types through the Strait.
- Data lags or reporting gaps in IMF Portwatch that could delay or obscure qualifying 7-day averages.
- Structural changes in global shipping patterns (e.g., more trade via alternative corridors) that lower baseline throughput.
- Requirement for a consecutive/semi-consecutive week of high daily calls to move the 7-day average, which is hard to achieve in short windows.
- Market consensus and liquidity that can underprice rare sudden normalization events, biasing apparent odds downward or upward unpredictably.
Scenarios
Best case
A rapid and credible de-escalation occurs (e.g., negotiated cessation of attacks, immediate lifting of specific route-based insurance surcharges, and fast redeployment decisions by major charterers), causing daily transit calls to climb above 60 for a sustained week and producing at least one published 7-day average >= 60 before June 15.
Most likely
Traffic remains below the historical-normal threshold through June 15 because rerouting and insurance considerations are slow to reverse, producing no qualifying 7-day average and a No resolution, though there remains a small chance of a rapid political/operational change producing a temporary seven-day recovery.
Worst case
Security conditions and commercial reluctance persist or worsen, daily transit counts remain well below the threshold, no qualifying 7-day average is published by June 15, and the market resolves to No as currently priced.
