Will Strait of Hormuz traffic not return to normal in 2026?

- [2026-02-28] IMF PortWatch's own disruption-monitor page states the Strait of Hormuz event is "28 February, 2026 — Ongoing," with "Attacks on commercial ships prompted shipping companies to stop sailing through the Strait of Hormuz, a systemically important shipping lane that facilitates about 25 percent of global oil maritime trade volume" — https://portwatch.imf.org/pages/cc317ba850e34c4dadbead6f7b336fb1 - [2026-02-24] Pre-disruption baseline: the Strait of Hormuz 7-day moving average reached 107.3 on 24 February 2026 just before the disruption, fell to a low of 2.7 in late March 2026 (RAND Forecasting Initiative summary of PortWatch data) — https://www.randforecastinginitiative.org/question_queue/questions/1767 - [2026-09-27] Most recent IMF PortWatch-dated data point cited repeatedly through early October: PortWatch recorded only 1 vessel transit on 2026-09-27, against a pre-crisis baseline of 85/day — https://straits.live/briefs/2026-10-06 - [2026-09-27] A compiled monthly series (sourced to IMF PortWatch AIS data) shows September 2026 transit totals of only 100 for the month through Sep 27, versus 5,389 year-to-date transits — "5,389 transits were recorded between January 1 and September 27, 2026, an average of 20.0 per day" , 78% below the same period in 2025 — https://www.globalmilitary.net/conflicts/strait-of-hormuz/transits/ - [2026-10-04] A separate tracker citing PortWatch reports 4 vessels transited on October 4 (5% of the ~85/day typical), still described as effectively closed to commercial shipping — https://straits.live/ - [2026-10-05/06] Attacks on tankers continue: UKMTO logged multiple incidents, including "at least two tankers... struck in the Strait of Hormuz in the past 24 hours" (Hellenic Shipping News, via straits.live), and India reported citizens injured aboard a Panama-flagged tanker hit on Oct 6 — https://straits.live/ - [2026-10-05] Al Jazeera reports crude exports have recovered: "Middle East oil exports have climbed back above levels seen before the US-Israel war on Iran began in February, despite Tehran's attempts to blockade the Strait of Hormuz and attack vessels" , but this is driven by bypass routes and ship-to-ship transfers, not an increase in AIS-tracked vessel transit calls — https://www.aljazeera.com/news/2026/10/5/is-iran-charging-a-toll-to-allow-oil-traffic-through-hormuz - [2026-10-05] Per Kpler data cited by Al Jazeera, "40 percent now bypass Hormuz, and most crude crossing the strait changes tankers offshore" , with flows diverted via Saudi/UAE pipelines and the Red Sea — this explains why barrel volumes can recover even while PortWatch's ship-count metric (the market's actual resolution variable) stays near zero — https://www.aljazeera.com/news/2026/10/5/is-iran-charging-a-toll-to-allow-oil-traffic-through-hormuz - [2026-08-27] Al Jazeera's six-month retrospective: "Traffic through the 33km (21-mile) chokepoint has fallen from more than 100 vessels a day to just five, disrupting the flow of oil, gas and goods worldwide" — https://www.aljazeera.com/news/2026/8/27/how-a-95-percent-drop-in-hormuz-traffic-changed-global-shipping - [2026-10-06] Major container lines (MSC, Maersk, CMA CGM, COSCO, Hapag-Lloyd, ONE, Evergreen, HMM, Yang Ming) remain in "rerouting" or "suspended" posture for Hormuz/Gulf calls per their own advisories, with no carrier reporting resumed normal-volume transits as of this date — https://straits.live/ - [2026-10-06] Sibling market data point (other venue, informational only): Kalshi's "before Jan 1, 2027" above-60 contract and "before Nov 1, 2026" contract were both trading at single-digit-to-low-teens implied probabilities per aggregator data, consistent with markets pricing a low chance of a qualifying ≥60 reading before year-end — https://straits.live/ - [2026-10-06] US officials (Defense Secretary Hegseth, per Times of Israel) continue to describe the naval posture around Iran as a blockade, and Iran continues to condition any reopening on its own terms, per multiple wire reports compiled by the tracker — https://straits.live/briefs/2026-10-06 BOTTOM LINE: As of the most recent IMF PortWatch-dated data (Sept 27 – Oct 4, 2026), daily transit calls are running at roughly 1–4 vessels versus an ~85/day pre-crisis baseline — nowhere near the 60 threshold required to trigger "Yes," despite oil-volume (barrel) flows partially recovering via bypass pipelines and ship-to-ship transfers. The underlying conflict, attacks on vessels, and carrier suspensions remain active and unresolved, making a qualifying ≥60 reading before year-end look currently very unlikely absent a major de-escalation. NOT FOUND: I could not find an IMF PortWatch data point later than 2026-09-27 (the series publishes weekly with roughly a 7-10 day lag), nor any single date since the disruption began on 2026-02-28 where the 7-day moving average has approached 60; I also could not independently verify the exact current Polymarket/Kalshi contract prices from a primary exchange page (only via the straits.live aggregator), consistent with the instruction not to rely on this contract's own stale price.

- [2026-05-04] Historical base-rate framing from Kalshi traders early in the crisis: markets *at that time* thought there's a 59% chance traffic returns to normal by September 1, with odds around 50% by August — these early estimates proved far too optimistic, illustrating the tendency to underestimate disruption duration. (cnbc.com) - [2026-07 forecast] A FutureSearch model synthesis noted the most credible resolution window was seen as late summer into early fall, aligning with maritime-security assessments that comprehensive mine-clearance and confidence-building would require 40–50 days , and that the probability curve plateaued around 80% by January 1, 2027, reflecting a ~20% residual tail risk of non-resolution — again overtaken by events as the conflict reignited repeatedly. (futuresearch.ai) - [undated, ~2026-05] RAND Forecasting Initiative's own base-rate question on recovery time noted the last time a convoy system was used in the middle of the Iran-Iraq war it took more than 18 months to clear the Straits , and forecasters split evenly (25% each) across 6/12/18/24+ month recovery buckets, reflecting deep uncertainty with a historical anchor toward slow, multi-year normalization. (randforecastinginitiative.org) - [Historical analogue] The Suez Canal — the standard comparator chokepoint — was blocked for four months in the 1956–57 crisis with minimal effect on the oil trade , but after the 1967 war was closed for eight years , showing that coercion/war-driven chokepoint closures (as opposed to accidental ones like the 2021 Ever Given) can persist far longer than single-year horizons. - [analytical comparison, ~2026-09] A dedicated Hormuz-vs-Suez analysis argues Hormuz fails through coercion and reopens when the coercion ends, unlike Suez's accident-driven closures, and a Hormuz closure "persists as long as the underlying conflict persists" — i.e., the relevant reference class is protracted political/military closures, not brief mechanical ones. (straits.live) - [2026-08-06/09-01] Prediction-market aggregation (Octagon) shows trajectory of collapsing optimism: confidence in normalization by Dec 31, 2026 was approximately 62% as of August 6, 2026 but by late August 2026 had fallen to approximately 34% , and by September a return to normal before Q4 2026 was widely considered improbable . (octagonai.co) - [2026-10-06] Most recent primary-adjacent data point: the World Bank's Middle East update cites the IMF's PortWatch monitor showing just three tankers moved through the strait in the seven-day moving average ending September 27 , and explicitly works on the assumption that the Strait of Hormuz will gradually reopen beginning on December 31 — i.e., the leading institutional forecast assumes normalization does NOT occur within the 2026 window. (thenationalnews.com) - [2026-09-05] UK Parliament research briefing reports the UAE's state-owned oil company estimates full flows through Hormuz will not resume until 2027, even if a deal is reached quickly — an industry-insider estimate pointing past the 2026 deadline. (commonslibrary.parliament.uk) - [2026-10-06, live tracker] As of the most recent published IMF PortWatch data, the 7-day moving average remains near-zero: on Oct 4, the most recently published day, commercial transit reached 5% of the pre-crisis vessel count — 4 vessels against a typical 85 per day , roughly 56 points below the 60-threshold needed to resolve "normal." (straits.live) - [sibling markets, snapshot 2026-10-06] Kalshi's equivalent threshold contracts price the "return to normal" event at low probabilities across near-term deadlines: 3% by Nov 1, 2026; 7% by Dec 1, 2026; 15% by Jan 1, 2027; and 48% by Jul 1, 2027 — showing the market-implied base rate rises sharply only once the horizon extends well past 2026. (straits.live) - [2026-08-25] A related Hormuz weekly-volume prediction market showed how quickly expectations swing with data: the probability of more than 45 vessels transiting during the week plummeted from 86% to 14% in the session ending August 25, 2026 , underscoring high realized volatility and repeated disappointment relative to earlier forecasts. (octagonai.co) - [no direct precedent] No historical instance was found of the Strait of Hormuz itself ever being fully or near-fully closed before 2026; prior "closures" were threats rather than realized blockages, per a Media Line historical review noting before the current war, the Strait of Hormuz had never been fully closed, even though Iran had threatened to do so many times — meaning this crisis is a true first-of-kind event with no Hormuz-specific base rate, only cross-chokepoint analogues (Suez, Tanker War convoys). BOTTOM LINE: The only close historical analogues (Suez 1956 four months; Suez 1967–75 eight years; Iran-Iraq War convoy clearance 18+ months) and the trajectory of this crisis itself (repeated false dawns, each forecast of near-term normalization proven wrong, current 7DMA near zero vs. the 60 threshold) both point toward slow, multi-quarter-to-multi-year recovery rather than a swift return to normal; institutional forecasters (World Bank, UAE state oil company) now explicitly assume no full normalization within 2026. NOT FOUND: No study quantifying a general "base rate" of how often chokepoint disruptions of this severity resolve within a 10-month window (analogous to the market's May–Dec 2026 period); no official IMF/PortWatch commentary assessing likelihood of 2026 resolution; could not access the RAND question's final/current crowd-updated probability (only an older "initial probability" snapshot was retrievable).

YES means: IMF PortWatch does not publish a 7-day moving average of Strait of Hormuz "Arrivals of Ships" ≥60 for any date in any calendar month of 2026 — i.e., the strait does not register a qualifying return to normal AIS-tracked transit activity before the market's 2026 window closes. - [2026-10-06] Attacks on shipping are *escalating*, not fading: Al Jazeera reports at least seven incidents involving tankers have been reported in the past week, according to shipping intelligence service Marisks , and separately that the security situation in the Strait of Hormuz has continued to deteriorate even as more oil moves out of the region — a mechanism-level reason PortWatch's vessel-count metric (distinct from barrel volumes) has no near-term path to 60. - [2026-10-06] A Panama-flagged Aframax, MT On Peace, was struck by a projectile transiting Hormuz, leaving at least 12 crew injured when the Panama-flagged tanker On Peace was struck by an unknown projectile in the Strait of Hormuz on 6 October ; UKMTO separately logged at least two tankers were struck in a 24-hour window, with a third vessel avoiding a hit after complying with instructions from an unidentified party . - [2026-10-04] A second confirmed hit the same week: on October 4, the Liberian-flagged Aframax tanker Lipsi was struck northeast of Oman's Jazirat Umm al-Fayarin, damaging its engine room, with no casualties reported — showing continuous kinetic risk even after the August mine-clearance. - [2026-10-06] Iran's Persian Gulf Strait Authority is actively blacklisting and punishing vessels that don't comply with its permit regime: the attacked tanker is one of 81 vessels on a blacklist from Persian Gulf Strait Authority's (PGSA) which it says are vessels that have violated Iran's protocols for the Strait of Hormuz and "shall face restrictions on future passages, including fines, detention, or confiscation" — an institutionalized deterrent to normal transit that didn't exist before this crisis and shows no sign of being dismantled. - [2026-08-25] Even after the U.S. announced full mine clearance of the main shipping lane (per Axios/CENTCOM), the structural insurance mechanism remains the binding constraint: as one analysis notes of the broader dynamic, capacity withdrawn at the treaty level cannot be reinstated by political announcement; it must be rebuilt through individual underwriting decisions. This is why a ceasefire does not immediately reopen the insurance market — meaning military de-escalation alone is insufficient for a PortWatch-measured return to 60+/day. - [2026-10-06] Major container lines remain in rerouting/suspended posture with no resumed normal-volume Hormuz calls (per colleagues' report), consistent with carriers independently judging the insurance/security environment unfit for routine transit despite the mine clearance. - [2026-10-05] Even the "recovery" narrative being used to argue against continued disruption is actually a YES-supporting data point once disaggregated: Al Jazeera's own reporting shows the barrel-volume rebound is explained by a senior Kpler analyst last week offered a different explanation for the rise in oil exports at high prices... "a race to get out as much as possible, as quickly as possible before the war restarts" , i.e., market participants expect renewed conflict, not durable normalization of transit counts. - [2026-10-06] Structurally, 40% of crude now permanently bypasses Hormuz via pipelines and ship-to-ship transfers (per colleagues' Oct 5 Al Jazeera citation), meaning even a full oil-flow recovery would not mechanically translate into a PortWatch vessel-count rebound to 60+, since fewer hulls are needed to move the same or more oil. - [2026-05-16 to 2026-10] The PGSA toll/permit regime has now been operating for nearly five months with no sign of removal: Tehran's apparatus requires vessels to disclose ownership, insurance, crew manifests, and cargo before being granted a permit , a bureaucratic friction layer that itself suppresses daily transit counts regardless of kinetic risk. - [2026-10-07, market structure] Sibling Kalshi contracts (per colleagues' snapshot) price Nov 1, Dec 1, and Jan 1, 2027 thresholds all in the single-to-low-teens percent range, reflecting that informed traders see the ≥60 threshold as very unlikely to be hit within the 2026 window given the above dynamics. BOTTOM LINE: The strongest case for YES (no 2026 return to normal) rests on an active, worsening kinetic threat (two attacks in 24 hours, 7 incidents in a week as of Oct 6), an institutionalized Iranian permit/toll/blacklist regime (PGSA) with no removal timeline, and a structural insurance/carrier-posture lag that persists even after the August mine-clearance — combined with evidence that oil-volume "recovery" headlines are decoupled from, and do not predict, the AIS vessel-count metric PortWatch actually measures. NOT FOUND: No evidence of any ceasefire, PGSA dissolution, or carrier announcement of resumed normal-volume Hormuz transit as of October 7, 2026; could not find a World Bank or UAE-oil-company estimate newer than the ones already cited by colleagues (Dec 31, 2026 gradual-reopening assumption; UAE 2027 full-flow estimate).

YES means: IMF PortWatch publishes a 7-day moving average of Strait of Hormuz transit calls ≥60 for some date in a calendar month before the end of 2026 (the qualifying "return to normal traffic" reading). - [2026-10-04] The most recent IMF PortWatch-dated reading (for Sep 27, repeated through Oct 4 briefs) shows transit calls still near zero — on OCT 4, IMF PortWatch's most recent published day, commercial transit through the Strait reached 5% of the pre-crisis vessel count: 4 vessels against a typical 85 per day , a gap of roughly 56 points below the 60 threshold with no upward inflection visible in the published series. - [2026-10-05] Negotiations remain stuck on the precise reopening dispute that PortWatch's ship-count metric would need resolved: a CBS live-update reports "After President Trump rejected Tehran's proposed conditions for reopening the Strait of Hormuz — while leaving the door open to further talks or renewed military operations — Iranian officials said the U.S. response was being reviewed, and it was preparing one of its own." - [2026-10-04] Iran's own leadership continues to publicly condition reopening on unmet US concessions: on October 4, Iran's parliamentary speaker, Mohammad Bagher Ghalibaf, said the strait will not reopen fully until the US meets Iranian demands, including a ceasefire on all fronts and the lifting of the US blockade of Iranian ports — a maximalist precondition unlikely to be resolved before year-end given the current trajectory. - [2026-10-05] Attacks that would deter the vessel traffic PortWatch counts are intensifying, not subsiding: CBS reports "forces have disabled three ships that refused to comply and redirected 130 commercial vessels attempting to pass through the strait, according to CENTCOM" , and separately a tanker "turns back in Strait of Hormuz after Iranian threats, U.K. navy maritime agency says" . - [2026-10-07] The US side (VP Vance) is hardening its negotiating demand rather than softening it, requiring "Iran must make a 'meaningful' reduction in its nuclear enrichment capacity to satisfy US demands and end the countries' seven-month war" — a precondition well beyond anything related to shipping access and a new bottleneck layered atop the existing Hormuz-control dispute. - [2026-10-07] Vance confirmed the military-pressure campaign on shipping continues deliberately: he "dismissed concerns about critical munitions shortages and added that while Iranian troops are periodically able to strike commercial ships in the Strait of Hormuz, they are largely unable to prevent energy exports through the waterway" — i.e., Washington's own framing accepts continued periodic strikes as the status quo, not a closure it expects to urgently end. - [2026-10-01] Trump personally rejected the most recent Iranian offer as insufficient specifically on strait access, telling TIME he had rejected Iran's latest peace proposal partly because they only offered to open "some aspects of" the Strait of Hormuz. "It's just not good enough, nearly," he said — confirming the two sides remain far apart on the exact issue PortWatch's metric would track. - [2026-10-01] Trump simultaneously threatened to escalate rather than de-escalate, saying new strikes after the midterms were "possible," and added: "We have a lot of weapons," renewing a threat he issued over the weekend — raising, not lowering, the odds of further disruption to shipping in Q4 2026. - [2026-10-01] US military posture is still building up in the region rather than winding down, with a U.S. official telling AP that three ships carrying over 7,000 sailors and 2,000 Marines are heading to the Middle East, which could mean three carriers are in the region as early as the end of October — inconsistent with an imminent negotiated reopening. - [2026-10-07] Independent reporting frames the conflict as a "stalemate" with no resolution timeline: "The US-Iran war has reached a stalemate in recent months" , compounded by a widening regional Yemen conflict that adds further instability pressure near the chokepoint network. - [2026-10-07] Compounding uncertainty on the Iranian side itself: Vance noted Washington was unsure how Tehran makes decisions in negotiations , and separately Trump said his "biggest problem" is not knowing who runs Iran — a leadership/command ambiguity that historically slows any formal reopening protocol requiring Iranian naval/IRGC sign-off. - [2026-10-06] Multiple live trackers independently corroborate PortWatch's near-zero reading persisting through the most recent publication window, with war-risk insurance still priced at roughly 40x normal and 220+ vessels holding position rather than transiting — structural deterrents (insurance, convoy/mine-clearance logistics) that would take weeks to unwind even after any political deal, making a sudden jump to a ≥60 7-day average within the remaining 2026 window mechanically difficult even in an optimistic ceasefire scenario. BOTTOM LINE: Every dimension of the dispute — the core Hormuz-control/fee issue, the newly added nuclear-enrichment precondition, continuing vessel attacks, hardening rhetoric from both Trump and Vance, and unresolved questions about who holds authority in Tehran — points to the conflict persisting past year-end, with the published PortWatch series still ~56 points below the 60 threshold as of the most recent data (Oct 4) and no negotiating breakthrough in sight that would both end hostilities and allow insurance/mine-clearance logistics to normalize before December 31, 2026. NOT FOUND: No IMF PortWatch data point newer than Sep 27/Oct 4 (as republished in trackers) could be located; no evidence of any de-escalation agreement, partial reopening protocol, or insurance-market repricing since early October that would suggest an imminent jump toward the 60-threshold within the remaining 2026 window.
