Our assessment

Issue of 26 October 2026

On day 241, the war has settled into a costly stalemate at sea. Lloyd's List and UKMTO count 28+ attacks in the first half of October, a record month. War-risk premiums run 6 to 10% of hull value per transit, against 0.25% before the war. The Pentagon reports 21 US service members killed and 865 wounded.

The live feeds show Hormuz still close to shut. PortWatch averaged 3.7 transits a day in the week to 18 October, down from 4.1 the week before and about 4% of the pre-war baseline of 85. JMIC puts escorted traffic near 34 a day, with 492 ships waiting off Fujairah and Khor Fakkan. Brent stood at $115.22 on 20 October, down 8.4% on the week. Our airspace feed returned no reading this week.

November is a cliff, not a resolution. Prediction markets give the US truce 84% odds of holding through the 3 November midterms, but only 29.5% of still holding on 31 December. The Israel and Iran truce stands at 38.5%, and normal Hormuz traffic by year end at 11.5%. We advise planning corridors for continued disruption into 2027.

Probability the truce survives to each date Polymarket, 27 Oct, 00:20 Israel time

"Ceasefire continues" on Polymarket means no US (or Israeli) air or missile strike on Iranian territory by that date. It does not mean a deal, and it does not cover the maritime war. The drop between 3 November and mid-November is the market's price on the decision window.

Maritime and airspace

IMF PortWatch and OpenSky

Strait of Hormuz, vessels a day IMF PortWatch, published to 18 Oct

Latest day: 4 vessels (2 tankers, 0 container, 2 dry bulk). Seven-day average 3.7 against 4.1 the week before, 4% of the pre-crisis 85 a day. PortWatch counts AIS-visible transits with a lag of one to two weeks; escorted and dark transits reported by JMIC run higher. JMIC reported 101 US-facilitated transits over 22-24 Oct and 492 vessels waiting outside the Strait on 25 Oct.

Aircraft airborne by region

No OpenSky samples yet. The first arrives with the next two-hourly run; a same-hour baseline builds over the first week.

Bab el-Mandeb, vessels a day IMF PortWatch, published to 18 Oct

Latest day: 32 vessels (17 tankers, 4 container, 6 dry bulk). Seven-day average 26.4 against 28.3 the week before, 44% of the pre-crisis 60 a day. PortWatch counts AIS-visible transits with a lag of one to two weeks; escorted and dark transits reported by JMIC run higher.

Suez Canal, vessels a day IMF PortWatch, published to 18 Oct

Latest day: 43 vessels (15 tankers, 15 container, 10 dry bulk). Seven-day average 44.3 against 41.7 the week before, 74% of the pre-crisis 60 a day. PortWatch counts AIS-visible transits with a lag of one to two weeks; escorted and dark transits reported by JMIC run higher.

Chokepoints and bypasses

RouteStatusLatest
Strait of HormuzContestedIran declares it closed; US escorts about 34 ships a day; mines, projectiles, GPS interference. JMIC threat level "severe".
Bab el-MandebHigh riskHouthis hold Perim, Hanish and the Yemeni coast; Saudi port blockade declared 20 Jul. No vessel attacks reported in September; Riyadh and Dammam airports struck 10-12 Oct.
Suez CanalRecoveringMaersk and Hapag-Lloyd return AE12 and SE1 services to Suez from 27 Oct. Canal revenue still depressed.
Saudi East-West pipeline (Yanbu)DamagedConverted to full crude capacity 11 Mar; pumping station struck 10 Sep; European refiners told to expect no Saudi crude in October.
UAE Habshan-FujairahOperatingPrimary UAE bypass; Fujairah anchorage congested.
Cape of Good HopeDefault+10-14 days Asia-Europe; container lines only now rotating back to Suez.
Net effect: Gulf crude shipments reached 75-81% of pre-war levels in September (IEA, Kpler) and Middle East exports via all routes exceeded pre-war volumes in the week to 18 Oct. Volume has largely recovered; cost, insurance and reliability have not. The IMF expects normalization through 2027, not a snap-back.

Energy and the cost of a barrel

FRED, EIA, broker quotes

Brent crude, dollars a barrel EIA via FRED, to 20 Oct

$115.22 on 20 Oct: -8.4% in 7 days, -3.7% in 30 days. 52-week high $138.21; 2026 average $95.3. EIA's October outlook has $105 in Q4 2026 and $84 in 2027; the gap to the forward curve is the deal-or-no-deal spread. FRED publishes with about a week's lag.

Hormuz war-risk premium
6-10% hull
Pre-war war-risk premium

~$35/bbl
Of which war-risk
~$7/bbl

A $100M tanker now pays $6-10M in war-risk cover per Hormuz transit, against about $250,000 before the war. Freight benchmarks are quoted before war-risk, so headline tanker rates understate the delivered cost. Container lines charge about $1,000 per box for a Hormuz transit; some discharge at Fujairah and truck to Jebel Ali.

How we got here

Five phases since 28 February
1
Epic Fury / Roaring Lion
28 Feb - 8 Apr
US-Israeli air campaign; Khamenei killed on day one, Mojtaba Khamenei succeeds. About 13,500 targets and 36,000 sorties. Iran closes Hormuz on 2 Mar and hits the Gulf states and Israel.
2
Ceasefire and blockade
8 Apr - 17 Jun
Pakistan-brokered two-week ceasefire, extended indefinitely on 21 Apr. Islamabad talks fail 11-12 Apr; US blockade of Iranian ports from 13 Apr. Epic Fury formally ended 5 May. Iran creates the Persian Gulf Strait Authority (transit permits).
3
Islamabad Memorandum
17 Jun - 8 Jul
MoU signed, blockade lifted, Strait reopens 18-19 Jun. Brent falls to about $72 by 1 Jul. Collapses after Iran strikes three vessels including a Qatari LNG carrier on 7 Jul.
4
Maritime attrition war
8 Jul - today
US strikes 7-31 Jul, blockade resumes 14 Jul. Houthis blockade Saudi ports (20 Jul) and seize Yemen's Red Sea coast (Sep). East-West pipeline struck 10 Sep. October: record attacks on shipping; Riyadh airport hit.
5
Decision window
3 Nov onward
Post-midterm strike plans drafted (NYT, 22 Oct). Iran's seven-day reopening plan still on offer. Either a deal and phased reopening, or "Epic Fury 2" with energy and nuclear targets.

Corridor impact

Our reading, up or down for business on each corridor

IsraelElevated

  • Israel is a planning partner for any post-midterm strike package; Netanyahu ordered strike preparations in early October, blocked by Washington at the last minute (JPost, CFR).
  • Iranian threat to widen targeting to data centers and undersea cables: direct exposure for Israel's tech and cloud sector and for Med-Red Sea connectivity.
  • Houthi control of Bab el-Mandeb keeps Eilat and the Red Sea leg of the Asia-Israel route at risk; Ashdod and Haifa via Suez or the Cape remain the working routes.
  • Lebanon front active since 2 Mar; Qatar funding southern Lebanon reconstruction (16 Oct).
  • Knesset election 27 Oct: the outcome shapes Israel's posture in the November window. See the Israel Election Tracker. Open the tracker

Latin AmericaMixed

  • Net exporters win on terms of trade: Brazil, Guyana, Argentina, Colombia, Venezuela. Petrobras, YPF and Ecopetrol rallied with Brent on 23 Oct. Guyana GDP forecast +16% in 2026.
  • Atlantic-basin barrels are structurally more valuable to Europe and Asia; LATAM was already the main source of non-OPEC supply growth in 2026.
  • Mexico exports crude but imports about half its gasoline; refined-product bills and the trade balance deteriorate even as Pemex export sales rose 31% y/y in Q2.
  • Brazil fertilizer exposure: 41% of urea imports transited Hormuz pre-war, 36% sourced from Gulf producers; yield risk for 2026/27 soy if supply stays tight.
  • Central America and the Caribbean: fuel importers with no commodity offset; currency and food inflation pressure.
  • US "economic D-Day" sanctions (24 Aug) raise secondary-sanctions risk for LATAM banks, shippers and traders touching Iranian cargoes.

Europe and EMEAElevated

  • Saudi crude to Europe interrupted: at least two European refiners told they get no Saudi barrels in October after the East-West pipeline strike.
  • Diesel market extremely tight (EIA): refinery margins squeezed by record freight; the IMF sees core inflation back at 2% only by mid-2028 in the US and Europe.
  • Egypt absorbs four shocks at once: energy import bill, Suez revenue, wheat prices, remittances.
  • Hapag-Lloyd and Maersk Suez returns from 27 Oct are the first sign of Red Sea normalization for Asia-Med trade; watch whether they hold through November.
  • Spain and the Western Med gain relative position as Atlantic LNG and LATAM crude entry points.

Gulf (GCC)Severe

  • IMF: GCC GDP -4.8% in 2026 (cut by 6.8 points since April); non-oil economy -0.8%; MENA plus Pakistan -1.3%.
  • Qatar: state revenues down 42% in H1 after strikes on energy facilities; LNG exports constrained; a Qatari LNG carrier was hit on 7 Jul.
  • Desalination plants struck: water security risk in Kuwait and Qatar (99% of drinking water).
  • Saudi Arabia: Riyadh and Dammam airports hit by Houthi missiles 10-12 Oct (12+ killed); Red Sea port blockade.
  • Rebound of +9.1% in 2027 projected if hostilities end and Hormuz reopens in early 2027; large reconstruction and resilience spend (pipelines, desalination, air defense).

Who gains, what is newGCC, Egypt, AsiaCorridor winners: LATAM oil premium fadesBrazil, Guyana, Atlantic LNGCorridor winners: losers: Mexico refined, Central America, EgyptCables, data centersNew vector: Iranian threat reported 22 Oct
What it looks likeA Pakistan- or Qatar-mediated sequence similar to June. Insurers reprice slowly (the June reopening lasted three weeks), so the first 30-60 days still carry elevated cost. The nuclear file is unresolved; Rubio and Vance insist on a "meaningful" enrichment cut and Tehran says it will never give up enrichment, which is why this scenario is fragile.The October pattern extends: Iran attacks to restore leverage, the US blockade strangles Iranian exports (floating stocks depleting since July), the Houthis keep Saudi Red Sea ports under threat. Volumes hold near 80% of pre-war via bypasses; cost and unreliability become the permanent tax. GCC contraction deepens, reconstruction spend is deferred.A short, intense campaign aimed at cratering Iran's economy to force concessions. Iran's stated response is to broaden targets from ships and energy to data centers and undersea cables, which puts Gulf cloud regions, Red Sea and Med cable landings, and Israel's digital infrastructure in scope. Expect Israeli home-front alerts, Gulf airport closures, a Houthi surge in the Red Sea, and a 10-14 day shipping freeze.
For our clientsLock in Gulf-route freight and cover early in the window; do not unwind Atlantic sourcing (LATAM crude, US LNG) until the memorandum survives 60 days. Israeli firms with Gulf partners: expect re-engagement to lag the political signal by a quarter.This is the scenario to budget for. Price contracts with war-risk pass-through clauses (CONWARTIME-type), diversify fertilizer and petrochemical sourcing for LATAM agriculture, and treat Gulf-dependent supply chains as a 2027 problem, not a Q4 2026 one.Pre-position: cyber and continuity plans for Gulf and Israel operations (we cover this through Cybool), cash and inventory buffers for Central American and Caribbean importers, and a review of any exposure to Gulf-based data hosting. Latin American exporters gain again, but the IMF-modelled $2.2T global hit from a renewed war would hit demand for their non-oil exports in 2027.
