# Current state
The Strait of Hormuz has been disrupted since the Feb 28, 2026 outbreak of the Iran-Israel/US war; as of Aug 19-20, 2026, IMF PortWatch-style transit counts remain far below the ~60-140/day pre-war baseline (recent weekly counts ~73-91 vessels/week, i.e., ~10-13/day by some trackers, though methodology varies). No qualifying 7-day MA ≥60 has been reported. Resolution requires PortWatch's own 7-day MA to hit ≥60 on any date before Dec 31, 2026; currently no durable ceasefire, and Iran/Oman "reopening" talks remain unresolved/collapsing.
# Timeline of key events
- 2023-2025: Baseline period — 7DMA averaged ~93.7 in 2025, commonly cited pre-war range 60-140/day (confirmed, RAND/PortWatch).
- 2026-02-24: Pre-crisis peak, 7DMA at 107.3 (confirmed, RAND).
- 2026-02-28: War/crisis begins; US/Israeli strikes on Iran, Iranian retaliation with mines/attacks (confirmed, Wikipedia/CFR).
- 2026-03 (late): Traffic collapses to 7DMA low of 2.7 (confirmed, RAND).
- 2026-04-19: 7DMA at 12.0, still far below normal (confirmed, RAND).
- 2026-06-23: Iranian Parliament Speaker Qalibaf states Strait management "will never return to the way it was before the war"; Iran establishes "Persian Gulf Strait Authority" requiring passage permits (reported, CRS).
- 2026-07-08 to 07-28: Continued low traffic, insurance surges (3-10% of hull value vs 0.25% pre-war), Iran rejects Oman reopening proposal, insists on wartime control (reported, multiple outlets).
- 2026-08-01 to 08-06: Brief uptick (84 transits July 27-Aug 2, up from 45 prior week); NPR reports "partial reopening appears close" via Iran-Oman deal (banning US/Israeli ships, 7% cargo fee) still under Iranian parliamentary review (reported).
- 2026-08-10 to 08-19: Traffic falls back — 73 transits (Aug 10-16) down from 91 prior week; NBC/CNN confirm traffic "nowhere near" pre-war 100+/day; Trump states no talks with Iran, blockade remains "in full force" (confirmed/reported, Lloyd's List, NBC, CNBC, Chicago Tribune).
- 2026-08-19-20: Reports of Iran "losing control" of Strait yet traffic remains subdued/unchanged amid US-Iran stalemate (reported).
# Event
Will the IMF PortWatch 7-day moving average of Strait of Hormuz transit calls fail to reach ≥60 for any month in 2026 (i.e., "no return to normal traffic")?
# Outcomes to forecast
- Yes (no qualifying month in 2026 — traffic does NOT return to normal)
- No (a qualifying month occurs — traffic DOES return to normal at some point in 2026)

# Sub-question answers
1. **Current 7DMA level vs 60**: Precise PortWatch figure not directly retrieved, but proxy trackers show ~73 transits/week (≈10-13/day 7DMA-equivalent) as of Aug 10-16, 2026, and other trackers cite near-total closure (1 vessel on Aug 16 per straits.live). All far below 60. [Lloyd's List, straits.live]
2. **2023-2025 baseline**: 7DMA averaged ~93.7 in 2025, peaked at 107.3 just before the war (Feb 24, 2026); commonly cited normal range 60-140/day — so 60 is near the low end of "normal." [RAND Forecasting Initiative]
3. **Cause/status**: 2026 Iran-Israel/US war (began Feb 28, 2026) with US/Israeli strikes, Iranian mining and attacks on shipping, and Iran's new "Persian Gulf Strait Authority" requiring transit permits. As of Aug 18-19, no active talks between US and Iran; naval blockade remains "in full force" per Trump. [Wikipedia, CRS, Chicago Tribune]
4. **30-60 day trend**: Volatile/oscillating, not steadily recovering — brief uptick late July (45→84 transits/week) reversed by mid-August (91→73 transits/week); described as "whiplash" pattern, not sustained trajectory toward 60+. [NBC, Lloyd's List]
5. **Insurance/shipowner behavior**: War-risk premiums surged to 3-10% of hull value (from 0.25% pre-war) as of July 2026 and IMO states "market pricing is not adjusting as conditions improve" — signals shipowners/insurers do NOT expect fast normalization. [The National, IMO]
6. **Sibling markets**: Polymarket "returns to normal by Aug 31" priced at 0.35% YES; "by Sept 30" at 4.5% YES — both imply near-certainty traffic will NOT normalize by those dates, consistent with sustained disruption through at least Q3 2026. [Polymarket]
# Key facts (high-confidence, factual)
1. [RAND] 2025 baseline 7DMA ~93.7; pre-crisis peak 107.3 (Feb 24, 2026); crisis low 2.7 (late March); 12.0 (Apr 19).
2. [CRS] Iran created "Persian Gulf Strait Authority" requiring passage permits; disruption persisted for ~5 months as of early August 2026.
3. [The National/IMO] War-risk insurance premiums remain 12-40x pre-war levels as of July 2026, not adjusting downward despite periods of calm.
4. [NPR] Iran-Oman reopening deal (banning US/Israeli vessels, 7% cargo fee, 20% fine) still pending Iranian parliamentary approval as of Aug 6, 2026.
5. [Lloyd's List/NBC] Weekly transit counts oscillating between ~45-91 vessels/week (roughly 6-13/day) through mid-August 2026, far below 60/day threshold.
# Cross-market signals
- **Kalshi related**: none found.
- **Polymarket (same-ticker)**: Current YES ("not return to normal") = 71.5%, up sharply from 35% a month ago (+23pp/30d, +14pp/7d) — strong recent momentum toward "Yes."
- **Polymarket sibling markets**: "Returns to normal by Aug 31" = 0.35% YES; "by Sept 30" = 4.5% YES — both imply <5% chance of near-term normalization, reinforcing persistent disruption view.
- **Related Iran markets**: "US ceasefire continues through Aug 31" = 86.5%; "through Sept 15" = 73.5% — ceasefire seen as fragile but currently holding, yet holding ceasefire ≠ traffic normalization (CFR notes recovery lags even with ceasefire due to mines/insurance/distrust).
# Analyst opinions and speculation
- CFR: full recovery will take "years, not months"; even a holding ceasefire leaves mines, infrastructure damage, transit fees, and insurance as multi-year drags.
- CFR: current ceasefire "on the verge of collapse," further threatening any recovery prospect.
- code_execution model (base case, generic hazard-rate assumptions, NOT calibrated to actual current low levels or reconciled with 71.5% Polymarket price) estimates ~12% probability of "No return" — this conflicts sharply with the market price and appears to underweight persistence/serial correlation and use stale market comparison (35% vs actual 71.5%); treat with low confidence.
# Directional lean per outcome
- **Yes (no return to normal)**: Strongly supported — current levels ~10-15% of 60 threshold, no ceasefire/reopening deal finalized, insurance markets pricing sustained risk, Iran's PGSA structurally altering transit regime, Polymarket up to 71.5% and rising, sibling near-term markets near 0-5% YES for normalization.
- **No (returns to normal)**: Weak support — only the abstract code-model (uncalibrated) and the theoretical possibility of rapid diplomatic breakthrough (Iran-Oman deal, ceasefire holding) could push levels up quickly; historical baseline shows 60 is achievable quickly once conflict resolves, but no evidence of imminent full resolution.
# Gaps / unknowns
- No direct Kalshi YES price was retrievable for this exact ticker — Polymarket is the only same-market cross-reference.
- Precise current PortWatch 7DMA figure not confirmed (proxies vary widely: 10-13/day vs near-zero per straits.live).
- Reconciliation needed between Lloyd's List (~10-13/day) and straits.live (~1/day) methodologies.
- Trajectory of Iran-Oman deal/parliamentary approval unresolved — could be a rapid catalyst if passed.
# Calibration anchors
- Polymarket YES (same market) = 71.5%, trending up (+23pp/30d) — primary anchor given no Kalshi data.
- Sibling "return by Aug 31/Sept 30" markets near 0-5% YES — strongly reinforces near-term persistence.
- Precedent: past Hormuz threats/tensions (2019, 2011-12) never produced sustained closure this long; current disruption already ~6 months (Feb-Aug 2026) is unprecedented, raising the bar for "normal recovery" base rates.
