Strait of Hormuz traffic returns to normal by July 31?
I assess a modest but small chance (15%) that IMF Portwatch will publish a 7-day moving average of Strait of Hormuz transit calls ≥60 on at least one date by July 31, 2026, because a short, sustained lull in regional incidents or a temporary spike in scheduled transits could push the seven-day average over the threshold, but ongoing security and economic factors make a sustained rebound unlikely in the next three weeks.
Analysis
Data for IMF Portwatch transit calls was not available to me at the time of this assessment, so this judgment relies on structural understanding of the Strait of Hormuz, typical shipping patterns, and the short calendar window remaining to July 31. A 7-day moving average of 60 requires either roughly seven consecutive daily counts near-or-above 60 or a short cluster of very high daily counts that lift the weekly mean; without knowing the recent baseline level, the size of the gap matters a lot. If the most recent 7-day average is already near the threshold (e.g., mid-50s), a brief lull in incidents or a scheduled wave of tanker and bulk transits could produce a qualifying datapoint; if the baseline is far below (e.g., 30s–40s), it would require an unusually large and sustained uptick in traffic in a short period, which is less plausible.
Market prices overwhelmingly favor No (market-implied Yes ~7.5%), signaling trader consensus that normal traffic levels will not be restored by the end of July; that consensus likely reflects an expectation of continued security risks, higher insurance/war-risk costs, and persistent rerouting of some cargoes. I place somewhat higher probability than the market because transient improvements (temporary ceasefires, rapid diplomatic breakthroughs, or scheduled convoy surges) are historically possible and can manifest quickly, producing one qualifying 7-day average even if the broader pattern remains subdued. However, those tail events are inherently low probability over a ~3 week horizon.
Operational and data considerations also matter: IMF Portwatch’s methodology, reporting lags, and revisions can change whether a given date qualifies, and the market’s resolution criterion accepts revisions made within the market timeframe, which slightly increases the chance that a borderline sequence will ultimately clear the threshold if later corrected upward. Conversely, if Portwatch’s reported coverage misses certain categories of ships or has temporary reporting gaps, that can suppress the observed counts even if traffic in reality rebounds, making the published series a partial reflection of on-the-water reality rather than a full census. Taken together, these technical and geopolitical dynamics produce a low but not negligible chance of seeing a qualifying 7-day average before July 31.
Arguments
For
- A short-lived ceasefire or de-escalation could allow a cluster of vessels to resume the Hormuz route and create a qualifying 7-day average.
- Seasonal increases in oil, LNG, or bulk shipments could temporarily raise daily transit counts above historical lows.
- Temporary reductions in insurance premiums or the use of naval escorts could lower barriers to transit and prompt a surge in calls.
- Reporting revisions within the market window could convert a borderline published sequence into a qualifying 7-day average.
Against
- Persistent security threats and attacks on shipping keep many operators routing around the Strait, sustaining depressed transit levels.
- High war-risk insurance and operational caution make it unlikely for charterers to resume the shortest, riskier passages quickly.
- Economic or logistical shifts that reroute cargo permanently mean transient improvements are unlikely to produce sustained averages above 60.
- Data coverage limitations or unchanged reporting practices at IMF Portwatch could mask real but partial recoveries of traffic.
Key drivers
- A rapid de-escalation or temporary ceasefire in the Gulf that reduces attacks and allows scheduled traffic to resume would quickly increase transit calls.
- Lowering of war-risk insurance premiums and charterers' perceived risk would prompt some rerouted voyages to return to the shorter Hormuz route.
- Scheduled commercial factors such as seasonal bulk, container, or tanker demand increases could raise daily transits independent of security changes.
- Coordinated naval escorts or enhanced security measures around chokepoints could restore operators' confidence and increase calls.
- Revisions or corrections to IMF Portwatch reporting within the market window could retroactively lift a previously borderline 7-day average above the threshold.
- Port congestion or bottlenecks elsewhere could temporarily divert additional traffic through Hormuz, boosting counts for a short window.
Risk factors
- Continued maritime attacks, missile/DRONE activity, or harassment by non-state actors will keep shipowners avoiding the Strait or transiting with delays.
- Sustained elevated war-risk and P&I insurance premiums will keep charterers routing around alternative longer but safer paths.
- Permanent commercial rerouting and longer-term supply-chain adjustments will blunt a rapid rebound in short-term transit counts.
- Geopolitical escalation between regional states would further depress transit calls and could produce prolonged disruption.
- Reporting gaps, undercounting, or conservative Portwatch classification choices could prevent publication of a qualifying 7-day average even if physical transits rise modestly.
- A short-time series effect where a single spike in daily calls is insufficient to raise the 7-day moving average above the threshold.
Scenarios
Best case
A rapid diplomatic breakthrough or effective, widely publicized security measures lead to seven consecutive days with daily transit calls at or above 60 (or a sequence that, with revisions, averages above 60), producing a single qualifying 7-day moving average before July 31 and triggering a Yes resolution.
Most likely
Some days show modest upticks in transits but not enough to sustain a 7-day average at or above 60, or reporting quirks keep the published moving averages below the threshold, resulting in a No resolution while leaving a small chance that a single short-lived improvement could have produced a Yes.
Worst case
Security incidents continue or escalate, insurance and charterer caution persist, and Portwatch reports remain subdued through July 31, leaving all 7-day averages below 60 and the market resolving No with no qualifying datapoint.
