Strait of Hormuz traffic returns to normal by October 31?

The market resolves Yes if IMF Portwatch's 7-day moving average of daily transit calls (Arrivals of Ships) for the Strait of Hormuz reaches 60 or higher for any date on or before October 31, 2026. The threshold of 60 is set meaningfully below the Strait's historical baseline, which has typically run in the range of roughly 70-100+ daily arrivals of container, dry bulk, ro-ro, general cargo, and tanker vessels. The market was created on August 10, 2026, implying a disruption had pushed the 7-day average below 60 at that time. Historical precedent strongly suggests Hormuz traffic is highly resilient: during past regional conflicts and insurance-spike episodes, transits dipped only modestly and recovered within weeks, because roughly a fifth of global oil and LNG volumes must transit the Strait and rerouting is extremely costly. Even a partial normalization over the ~12-week window from market creation to October 31 would likely lift the 7-day average back above 60. I could not retrieve live IMF Portwatch data within this session, so this assessment rests on baseline levels and historical recovery patterns rather than verified current readings, which limits confidence.

The available evidence indicates that while there have been discussions and potential agreements to restore traffic through the Strait of Hormuz, there is no definitive confirmation that traffic will return to normal levels by October 31, 2026. The situation remains fluid, with ongoing negotiations and the potential for unforeseen developments. Therefore, it is more prudent to consider the likelihood of traffic not returning to normal by the specified deadline as higher.

As of the 5 September 2026 cutoff, IMF PortWatch Strait of Hormuz 7-day moving-average transit calls remain well below the 60 threshold that would resolve this market Yes. The official PortWatch chokepoint page and downloadable daily series still show a post-June 2026 collapse from a pre-crisis normal of about 90–110 daily transits to roughly 10–20, with the 7-day MA typically in the mid-teens. A 56-day window to 31 October 2026 is theoretically enough for a rebound if the strait fully reopened, but contemporaneous reporting through early September describes continued military risk, insurance premia, and rerouting rather than a restored commercial schedule. Reaching a 7-day MA of 60 requires a sustained run of roughly 60-plus daily calls, not a one-day spike; that has not occurred on the resolution source and is not the path implied by still-elevated disruption indicators. The market therefore more likely resolves No unless an unannounced, rapid, and durable reopening appears in PortWatch data before the deadline.

The market requires the IMF Portwatch 7-day moving average of transit calls to reach at least 60 by October 31, 2026. Pre-conflict baseline traffic was approximately 129-138 ships per day [9][30]. During the height of the conflict in March and April 2026, traffic collapsed to an average of just 3 tankers per day, with some reports indicating a 97% decline [9][28]. Although a ceasefire and Memorandum of Understanding (MoU) were signed in June 2026 aiming to restore traffic, implementation has been fragile and partial. Reports from May 2026 showed a rebound to 54 ships in a week (approx. 7.7 daily average), which is far below the 60-ship threshold [26]. By July 2026, tensions flared again with strikes and accusations of ceasefire violations, hindering a full return to normalcy [5][3]. While the MoU stipulated a potential return to pre-war levels within 30 days of finalization [29], the persistent geopolitical friction, Iranian control mechanisms (fees/inspections), and the fact that traffic remains a 'fraction' of pre-war levels suggest that reaching a sustained 7-day moving average of 60 ships (nearly half of pre-war volume) by late October is unlikely given the slow and volatile recovery trajectory observed through August 2026.

As of September 5, 2026, public access to the required IMF Portwatch Strait of Hormuz transit data page is restricted or unavailable, with no verified published 7-day moving average of transit calls equal to or above 60 recorded under the specified criteria up to this knowledge cutoff date, making it highly unlikely the threshold will be met by the October 31, 2026 deadline.

As of early September 2026, transit calls through the Strait of Hormuz according to IMF PortWatch remain severely depressed, averaging roughly 4 to 7 vessels per day compared to pre-conflict levels of 85 to 140 per day. For the market to resolve to 'Yes', IMF PortWatch must report a 7-day moving average of at least 60 vessel transits (totaling 420 transits in a 7-day window) by October 31, 2026. Given ongoing military exchanges between US forces and Iranian assets, persistent GPS jamming, mine threats, high maritime insurance rates, and the lack of a comprehensive diplomatic resolution, a near tenfold surge in shipping traffic within less than eight weeks is highly unlikely.

Verified through the September 5 cutoff: the latest IMF PortWatch observation is August 30. My calculation from the official daily series gives a 7-day average of 4.29 (30 calls in seven days), while the highest eligible average since the August 10 market opening is 6.00. The trigger requires 60, or 420 calls in seven days. After JMIC declared the Strait open on June 18, the same PortWatch series peaked at only 31.86 on June 29 before retreating, showing that even a reopening announcement did not produce threshold-level monitored traffic. With security conditions again deteriorating and large operators still using restrictions and workarounds, my forecast is NO.

NO is the most likely outcome. As of September 5, IMF PortWatch-linked evidence shows Strait of Hormuz traffic still at single-digit or low-teens daily levels, far below the 60-call 7-day-average threshold. The latest reported PortWatch observation was 6 transits on August 30, against a pre-crisis baseline of about 85 per day, while Reuters reported only around five vessels on September 1 and a recent 10-day average near 14. Reaching a 60-day 7-day average before October 31 would require a rapid and sustained return to roughly 70% of the pre-crisis baseline, with no evidence of that recovery yet. [web:31][web:1][web:16]

As of September 5, 2026, the IMF PortWatch 7-day moving average for Strait of Hormuz transit calls stands at approximately 5-6 vessels, far below the 60 threshold required for normalization. The US-Iran Memorandum of Understanding lapsed on August 17 without extension or a final agreement, while recent military tensions have escalated, and war-risk insurance costs remain prohibitive (40× pre-crisis levels). Multiple authoritative sources, including shipping industry leaders and financial institutions, project normalization will not occur until 2027 at the earliest. The required 12-fold increase in just 8 weeks faces insurmountable obstacles including mine clearance, insurance availability, and geopolitical instability.

As of 5 Sep 2026 the Strait has been effectively closed ~188 days. IMF PortWatch's last published day (30 Aug 2026) recorded only 6 transits versus a pre-crisis baseline of ~85/day — about 7% of normal. The 7-day moving average of transit calls is far below the 60 threshold. With an active, escalating Iran–US conflict (a US missile strike on an Iranian tanker near Kharg Island was reported on 5 Sep), crisis pressure at extreme levels, war-risk insurance ~40x pre-crisis, and ~410 vessels holding position, a recovery to a 7-day MA >=60 by 31 Oct is highly improbable. Linked markets price the near-term deadline at 2–3%.

IMF PortWatch's own chokepoint series shows Strait of Hormuz transit calls collapsed to a trickle and have stayed there. The latest published day at the cutoff, 30 August 2026, recorded 6 transits, and the 7-day moving average for 24-30 August is roughly 4.3 - against a pre-crisis baseline near 88/day (PortWatch October 2025 mean 87.8). Reaching the market's threshold of 60 requires an approximately 14x increase sustained over a full week, all on dates no later than 31 October 2026, leaving under eight weeks. The most informative precedent is decisive: during the June-July MoU reopening - the single most favorable episode of the crisis, featuring a US-Iran ceasefire, toll-free passage, and a backlog of roughly 1,500 trapped vessels straining to exit - daily transits peaked at 51 (24 June) and the 7-day moving average topped out near 32 (29 June), barely half the threshold, before decaying as the arrangement collapsed. If a backlog-driven surge under a live political agreement could not clear 60, a cold start from ~4 within eight weeks is far harder. The situation at the cutoff is escalating rather than normalizing: the June MoU expired on 17 August, Iran conditions reopening on the US lifting its naval blockade, removing sanctions and paying war compensation, no direct US-Iran talks are underway, Trump has said he is 'in no hurry,' and early September saw fresh strikes on tankers and US-Iran exchanges in the strait. Even a sudden political breakthrough would still face mine clearance (Iran and Oman are only planning a joint clearing project), war-risk insurance running roughly 40x pre-crisis at about $10M per supertanker, and multi-week service-loop restoration for the eight of nine major carriers now routing via the Cape of Good Hope. A further asymmetry cuts against Yes: PortWatch relies on AIS, and the widespread dark transits and ship-to-ship transfers now in use mean measured transits understate actual movement, biasing the resolution metric downward. I therefore expect No.

As of early September 2026, independent shipping trackers and news reports put daily ship transits through the Strait of Hormuz in single digits (roughly 4–10 vessels), implying a 7-day moving average of IMF Portwatch transit calls far below the 60 required for this market. The US–Iran conflict has kept the strait effectively closed, and despite an Iran–Oman interim-corridor framework and US claims that oil flow is nearly back to pre-war levels, those 'recovery' claims measure barrels (largely rerouted via pipelines/alternative routes), not Portwatch ship arrivals. With only about eight weeks left before October 31, a sustained >10x jump to a 60 seven-day average is a long-tail scenario.

IMF Portwatch's own data feed shows Strait of Hormuz transit calls at only 1-10 ships per day through 2026-08-30 (7-day moving average ~4.3), versus the >=60 threshold needed for YES. Since the 2026 Iran War began in late February, the 7-day average has never reached 60, and even the best relief window (the June 24-July 9 US-Iran MoU) peaked at just 26.71. The conflict is currently escalating - the US reimposed its naval blockade on July 14, announced an 'Economic D-Day' sanctions campaign on August 19, and a tanker was struck in the strait as recently as August 26 - making a roughly 14-fold sustained recovery in shipping traffic within the remaining eight weeks highly improbable.

As of September 5, 2026, the 7-day moving average of transit calls (Arrivals of Ships) for the Strait of Hormuz, as reported by IMF PortWatch and corroborated by multiple independent sources, remains far below the threshold of 60 required for a 'Yes' resolution. The most recent data from August 30, 2026, indicates only 6 transits per day, which is approximately 7% of pre-crisis levels (85 transits per day). This is consistent with reports that commercial traffic through the Strait of Hormuz is operating at a fraction of its normal capacity due to ongoing geopolitical tensions, military actions, and Iranian control measures. IMF PortWatch data and third-party tracking platforms (e.g., MacroMicro, straits.live) confirm that the 7-day moving average has not reached or exceeded 60 transits at any point between market creation and September 5, 2026. Diplomatic negotiations between Iran, Oman, and the U.S. to reopen the strait are ongoing, but as of the cutoff date, no agreement has been implemented, and traffic levels remain suppressed. The resolution criteria specify that the market will only resolve to 'Yes' if IMF PortWatch publishes a 7-day moving average of transit calls equal to or above 60 for any date up to October 31, 2026. Based on the available evidence, this outcome is highly unlikely unless there is a sudden and dramatic increase in traffic, which is not supported by current trends or diplomatic developments.
