Strait of Hormuz traffic returns to normal by July 15?
I estimate a 30% probability that IMF Portwatch will publish a 7-day moving average of transit calls for the Strait of Hormuz at or above 60 on any date up to July 15, 2026, reflecting some chance of rapid traffic rebound but significant ongoing downside risks from security and rerouting.
Analysis
The market currently prices the Yes outcome at roughly 23.5%, which implies market participants see a low probability of a return-to-normal level by July 15; given there are about three weeks left, this is a short time horizon in which a few high-volume days can materially affect a 7-day moving average if the baseline is already near the threshold. The contract’s resolution rule (single qualifying date and inclusion of revisions within the timeframe) means that even a temporary spike or subsequent upward revision can produce a Yes outcome, so statistical tail events matter more than in longer horizons.
I do not have fresh IMF Portwatch numbers in front of me, so I treat the current baseline as uncertain; if recent daily call counts are materially below 60 on a 7-day average, the probability of recovery in three weeks declines sharply, whereas a baseline near 55–59 would make a one-week rebound quite plausible. Shipping volumes through the Strait are driven by a mix of tanker and non-tanker traffic, and merchant flows can re-concentrate quickly if perceived security risks diminish, but they can also remain depressed for extended periods if carriers and insurers view the corridor as unstable.
Geopolitical and security conditions are the chief external drivers: any de-escalation, visible removal of threats, or credible international naval presence could prompt insurers and charterers to resume transits and close alternative routes, producing a rapid bounce. Conversely, a new incident or escalation would sustain or deepen rerouting away from the Strait and keep the 7-day average depressed; these events are hard to predict but have outsized impact on near-term probabilities.
Data and reporting mechanics add an important second-order effect: IMF Portwatch’s published series and allowance for revisions within the market timeframe mean that retroactive upward corrections could convert an otherwise losing window into a winning one, and intermittent reporting or clerical corrections can change the picture late in the period; however, the market will not consider revisions after data for July 15 is published, limiting post-period salvage options.
Arguments
For
- A short-term de-escalation or diplomatic breakthrough could quickly restore commercial confidence and prompt a surge of transits.
- Operational backlogs and waiting vessels can clear in a concentrated burst, producing several high-count days that lift a 7-day average.
- Insurance premiums could fall quickly if military risk subsides, removing a major barrier to ships resuming the Strait route.
- IMF Portwatch revisions published within the market window could retroactively raise the moving average above the threshold.
- Non-tanker traffic (container, dry bulk, general cargo) can return independently of tanker flows and help reach the aggregate threshold.
Against
- Ongoing or renewed maritime attacks, interceptions, or military encounters would sustain avoidance and keep counts depressed.
- Charterers and insurers may prefer the predictability of long detours even after a short lull in hostilities, slowing the return to prior volumes.
- A multi-week lag in commercial decision-making and repositioning means traffic often recovers more slowly than headlines suggest.
- If the current 7-day average is well below 60, the remaining time window may be insufficient for a sustained rebound to lift the moving average.
- Data coverage and reporting idiosyncrasies could undercount certain vessel types in IMF Portwatch and thus prevent a qualifying publication even if regional activity increases.
Key drivers
- Current baseline 7-day moving average level relative to the 60 threshold determines how large a rebound is needed and how likely it is within three weeks.
- Short-term geopolitical developments and any new maritime security incidents in or near the Strait will rapidly alter routing and insurer behavior.
- Insurance premiums and war-risk assessments that determine whether commercial operators resume normal transits through the Strait.
- Global tanker demand and commodity flows that influence how many vessels have economic incentive to take the shorter Hormuz route versus longer detours.
- IMF Portwatch reporting cadence and the possibility of data revisions during the market’s timeframe that can retroactively qualify a date.
Risk factors
- A new security incident or escalation involving Iran or regional actors that sustains or increases avoidance of the Strait.
- Persistent high insurance premiums or client directives that keep tonnage rerouted via longer paths like the Cape of Good Hope.
- Structural shifts in shipping patterns that reduce non-tanker commercial transit through the corridor over the medium term.
- Data reporting gaps or delays that compress the window for corrective revisions and reduce the chance of a qualifying published value before July 15.
- Insufficient recovery in demand for crude and other commodities that would otherwise generate more transits through the Strait.
Scenarios
Best case
A clear de-escalation (diplomatic or operational) coupled with falling insurance premiums and a few consecutive high-transit days pushes the IMF Portwatch 7-day moving average above 60, with possible supporting revisions during the window that reinforce the Yes outcome.
Most likely
Modest improvement in some vessel classes but not enough aggregate increase to cross the 60 threshold, so temporary gains fall short of producing a qualifying 7-day moving average and the market resolves No.
Worst case
A new maritime security incident or prolonged geopolitical escalation leads to sustained rerouting and depressed traffic, keeping the 7-day moving average below 60 through July 15 and resulting in a No resolution.
