Strait of Hormuz
critical · deterioratingAttacks reached a record in October while flow estimates diverge: Kpler puts October crude through Hormuz at 16.7m b/d against about 19m pre-war, and ANZ put flows near 60% of normal. PortWatch shows 3.3 visible transits a day to 25 October, a floor, not total throughput.
- Washington Institute: 30 ship attacks in October to 28 October, a record month.
- UKMTO, 29 October: tanker on fire nine miles north of Khasab; vessel not named.
- IRGC claims three tankers hit mines on 29 October; CENTCOM rejects the claim.
UK relevance: Continued disruption sustains British freight, fuel and inflation pressure; the Saudi shuttle keeps some Gulf crude moving, but to Asian buyers, not the Atlantic-basin cargoes UK refiners compete for.
Watch next: Whether Iran's threatened action against 'unauthorised' transits from 1 November stops ships, whether owners confirm any IRGC claim, and whether talks or strikes after the 3 November midterms change flows.

Red Sea & Bab el-Mandeb
critical · deterioratingHouthi strikes now target Saudi export plant, but none has been shown to cut supply: a 27 October attack started a fire at the Ras Tanura terminal that a source told Bloomberg was contained. Claimed hits on Yanbu, Rabigh and the East–West pipeline remain unconfirmed, and no change at Bab el-Mandeb has been reported.
- 27 October: fire at Ras Tanura terminal after Houthi attack; contained, a source told Bloomberg.
- 24–29 October: Houthis claim Yanbu, Rabigh, pipeline and Abqaiq strikes; no damage confirmed.
- 29 October: Saudi air defences intercept a missile aimed at the Eastern Province.
UK relevance: With Yanbu loading at about a third of its pre-attack rate, European refiners are still competing for the same alternative cargoes British refiners source.
Watch next: Whether any strike is shown to cut loadings at Ras Tanura, Yanbu or Rabigh, whether East–West pipeline throughput can be confirmed, and whether Egypt deploys to defend Saudi Arabia.

Black Sea logistics
elevated · deterioratingNo recovery in Black Sea product exports has been reported since diesel and gasoil loadings fell to zero in the week to 24 September, a first in S&P Global records. War-risk cover has risen sharply; no new port strike or Sheskharis halt was confirmed between 5 and 22 October.
- No October Black Sea diesel or gasoil export figure found; the last S&P reading was zero.
- Broker Sobol: war-risk premiums up from 0.1% to 0.5%, confirmed by insurers 6 October.
- Russia partially lifted its diesel export ban on 10 October, permitting 500,000 tonnes.
UK relevance: Black Sea disruption tightens the European product and grain balances that set prices the UK imports.
Watch next: Whether Black Sea product loadings restart under the 500,000-tonne allowance or if the producer ban lapses on 31 October.

European rivers
criticalThe Rhine at Kaub dipped below gauge zero again on 6–8 October and read 17cm at midday on 22 October, still far too low for normal barge loading. Both Cernavodă reactors remain in safe shutdown; Nuclearelectrica's planning assumes grid reconnection from 1 November, not a confirmed restart.
- Kaub raw gauge: −2cm on 7–8 October, a 22cm high on 12 October, 17cm on 22 October.
- Nuclearelectrica, 11 October: Cernavodă units 1 and 2 held in safe shutdown.
- Platts, 7 October: Lobith and Cologne near record lows; ARA–Karlsruhe barges about €200 a tonne.
UK relevance: European power and freight strain raises the imported energy and goods costs that reach UK consumers.
Watch next: Whether autumn rain lifts Kaub above about 30cm, where most barges can load again, and whether Cernavodă reconnects from 1 November as planned.

Oil products
criticalUS retail diesel was $6.352 a gallon in the week of 26 October (EIA), and AAA's average was $6.32 on 30 October, against $6.41 a month earlier. US distillate stocks are 99.3 million barrels, about 13% below the five-year average for the week to 30 October.
- EIA: retail diesel $6.352 a gallon, week of 26 October, up from $6.276.
- AAA: diesel $6.32 on 30 October, against $6.41 a month earlier.
- EIA: distillate stocks fell 1.5m barrels in the week to 23 October, 10% below average.
UK relevance: Product tightness, not crude, is the channel that reaches UK pump, freight and heating costs fastest.
Watch next: The 3 November EIA retail diesel reading, whether the first Russian cargo reaching New York around 7 November moves US prices, and whether distillate stocks fall towards 100 million barrels.

Russian refining
criticalCorrectionStrikes resumed after a three-day pause: Ukraine hit the Ryazan refinery on 15 October, and Volgograd, about 5% of Russian capacity, stopped all processing after a 2 October attack. Moscow eased its diesel export ban on 10 October only to permit 500,000 tonnes; the producer ban still runs to 31 October.
- Ryazan refinery struck 15 October after the energy pause ended; debris started a fire (AP).
- Volgograd stopped all crude processing after the 2 October drone attack (Reuters).
- Interfax, 20 October: producer diesel ban in force to 31 October, no extension announced.
UK relevance: Lost Russian refining removes diesel from the global pool a net-diesel-importing UK buys from.
Watch next: Whether the producer ban is extended past 31 October, and whether Ryazan and Volgograd restart or join the plants already offline.

Global diesel
criticalUS distillate stocks are 99.3 million barrels, about 13% below the five-year average for the week to 30 October. Europe will release about 42m barrels of emergency stocks, roughly half diesel, Russia's first US-bound diesel cargo sailed on 23 October, and Reuters reports Moscow will extend its diesel export ban to year-end.
- France, 29 October: Europe to release about 42m barrels over three months, roughly half diesel.
- Kremlin, 23 October: first 40,000-tonne diesel cargo sailed for the US; due about 7 November.
- Reuters, 29 October: Russian diesel export ban to be extended to year-end; no decree yet.
UK relevance: Diesel is the fast transmission channel into UK trucking, farming and food distribution — fuel the UK imports rather than refines.
Watch next: Whether Moscow issues the export-ban decree and November quotas, whether the US-bound cargo discharges in New York, and how quickly Europe's release reaches distributors.

Middle East conflict
critical · deterioratingNo deal: Saudi, Pakistani, Turkish and Iranian officials meeting in Tehran on 26–27 October agreed only to keep talking, and an Iranian official called Qatar's draft 'unacceptable ideas and not an offer'. Mediators aim to restart US–Iran talks after the 3 November midterms, while the US blockade of Iranian ports continues.
- 26–27 October, Tehran: Saudi, Pakistani, Turkish and Iranian officials agree only to keep talking.
- 28 October: Iranian official calls Qatar's draft 'unacceptable ideas and not an offer'.
- WSJ, 29 October: Gulf states told to prepare for a short US campaign after 3 November.
UK relevance: Strikes on Saudi export infrastructure now feed directly into the crude and product prices UK importers pay.
Watch next: Whether talks restart after the 3 November midterms or reported US strike planning becomes action, and whether Egypt deploys under its new parliamentary authorisation.

Arctic / Northern Sea Route
elevatedRussia shipped about 20m barrels of oil to Asia through the Northern Sea Route from July to mid-October, about 50% more than in the whole 2025 season, and Rosatom expects a record 7m tonnes of transit cargo. The route is normally open from July to October, so the season is now closing.
- Reuters/LSEG: about 20m barrels to Asia via the route by mid-October, against 13m in 2025.
- CHNL: 104 transits to 30 September, already above the 2025 total of 103.
- Rosatom, 27 October: transit cargo expected to double to a record 7m tonnes.
UK relevance: The route’s seasonal limits cap one of the few detours easing pressure on the corridors that set the prices the UK imports at.
Watch next: Whether late-season tankers clear the eastern sector before ice closes it, and whether a final season crude total is published.

US strategic buffer
elevatedThe Strategic Petroleum Reserve is 282.2 million barrels, down 0.4 on the week, while commercial crude ex-SPR drew 0.9 million to 409.8 million. Distillate at 99.3 million is about 13% below its five-year average.
- SPR fell 0.4 million to 282.2 million in the week to 30 October.
- Commercial crude ex-SPR drew 0.9 million to 409.8 million (EIA, week to 30 October).
- Distillate drew 3.6 million to 99.3 million, about 13% below the five-year average for the week.
UK relevance: A thinner US emergency buffer weakens the system’s insurance against the next disruption, leaving the prices the UK imports at more exposed.
Watch next: Whether distillate stops drawing before the heating season, and whether SPR releases continue at this pace.

CPC / Kazakhstan
elevatedNo disruption to CPC loadings has been reported since a brief halt on 8 September, and no October drone incident at the terminal or its pump stations was found. No breach of Ukraine's August pledge not to target CPC has been reported, so the exposure is reduced, not removed.
- No CPC loading halt or terminal incident found between 5 and 22 October.
- Last incident: two moorings briefly halted after an 8 September drone incident.
- Kazakh output 1.92 million b/d in September, down 7% on Karachaganak maintenance.
UK relevance: Lost CPC barrels tighten the European refining system that supplies the products the UK imports.
Watch next: Whether Ukraine's pledge holds as strikes on Russian energy resume, and whether October export data show CPC back near 1.6 million b/d.

LNG
criticalQatari LNG is leaving Hormuz only in small numbers, every count a floor because of dark transits, and two damaged Ras Laffan trains, about 17% of capacity, need about three years of repairs. EU storage was 74.6% full on 21 October, and Kpler puts Europe's October LNG imports at 9.11 Mt, below a year earlier.
- Baird Maritime: four laden Qatari carriers reappeared outside Hormuz around 2–3 October.
- Kpler via Clyde Russell: Europe's October LNG imports 9.11 Mt, against 10.59 Mt a year earlier.
- Edison: QatarEnergy force majeure on its cargoes extended until early December.
UK relevance: Qatar’s replacement buying removes Atlantic cargoes that would otherwise supply the European market the UK draws gas from.
Watch next: Whether Qatari exits keep rising and EU storage can reach the 80% flexed floor before 1 December as German stocks begin to draw.

Financial transmission
elevated · deterioratingThe first marker peaked and pulled back: the 30-year Treasury yield closed at 5.67% on 7 October, its highest since 2002, then 5.37% on 28 October as the Fed held rates. The second marker has not fired: the yen stayed between about ¥156.9 and ¥158.8 to the dollar in October, without intervention.
- FRED: 30-year yield 5.67% on 7 October, highest since 2002; 5.37% on 28 October.
- Fed, 28 October: rates held at 3.75–4.00%; two dissents favoured a hike.
- BoJ, 30 October: rate held at 1.25%; FY2027 inflation forecast raised to 2.6%.
UK relevance: Energy-driven rate repricing raises borrowing costs in the gilt market alongside Treasuries while equities weaken.
Watch next: Whether the yen breaks back through ¥160 into renewed intervention, or a disorderly yen rally forces carry positions into repayment.

Sulphur & phosphate fertiliser
criticalSulphur scarcity is still cutting phosphate output: Mosaic's US and Brazil curtailments stand and no restart has been reported. Chinese sulphur prices fell nearly 16% in the month to 22 September, but supply stays tight, and DAP averaged $800.6 a tonne in September, its highest this year.
- DAP averaged $800.6/t in September (World Bank), up from $793.5 in August.
- Chinese ex-works sulphur down nearly 16% month-on-month to 22 September (SMM via Global Agriculture).
- Uberaba hibernation was scheduled for September; no confirmation it began, nor any restart reported.
UK relevance: Fertiliser supply risk feeds the food-price exposure of a country importing close to half its food with almost no domestic fertiliser production left.
Watch next: Mosaic's third-quarter volumes and fourth-quarter sulphur settlement — the first hard read on whether curtailments deepened or eased.

Chinese fertiliser controls
elevatedChina is still withholding phosphate: the DAP and MAP suspension's August end date passed with no resumption or successor policy reported. Urea moved the other way — Bloomberg reports the 2026 allowance raised to about 5–5.5 million tonnes, with at least 1.2 million tonnes sold to India — and sulphuric acid exports remain halted.
- Urea allowance raised to about 5–5.5 million tonnes, from 3.3 million (Bloomberg, people familiar).
- At least 1.2 million tonnes to India's tender, loading by 24 September.
- No resumption of DAP/MAP exports reported after the suspension's August end date.
UK relevance: Retained Chinese supply tightens the world fertiliser market a food-importing UK depends on.
Watch next: Whether Beijing formally extends the phosphate suspension into winter stockpiling or reopens DAP and MAP under quota.

Brazil fertiliser exposure
elevatedBrazil is entering soybean planting on sharply fewer imported inputs: fertiliser arrivals in the first 13 business days of September ran about 30% below a year earlier, after January–August imports fell to 25.4 million tonnes. Planting itself is on pace and USDA has not cut its 186 million-tonne soybean forecast, so input loss has not yet become production loss.
- September fertiliser arrivals averaged 137,300 tonnes a day over 13 business days, down 29.9%.
- January–August fertiliser imports 25.37 million tonnes, lowest for the period since 2023; urea 2.82 million.
- Soybean planting reached 3.4% by 24 September, against 3.2% a year earlier (AgRural).
UK relevance: A weaker Brazilian harvest would tighten the global food balances behind UK import prices.
Watch next: October planting pace and whether reduced phosphate and nitrogen use starts to appear in yield forecasts.

Mexico
elevatedNo state changeUSDA holds Mexico's 2026/27 corn production at 24.6 million tonnes and still projects imports of 27.2 — more than the country grows — so the structural exposure stands. The US price channel has cooled: fruit and vegetable prices were 3.2% above a year earlier in August, down from 5.1% in July.
- September WASDE: Mexico corn imports cut 0.5 to 27.2 million tonnes; feed use cut 0.7.
- Mexico corn production unchanged at 24.6 million tonnes for a second month.
- US fruit and vegetable CPI up 3.2% year-on-year in August, down 0.4% on the month.

Global grain balance
elevatedUSDA's September report still puts both wheat and corn below consumption in 2026/27, and the split between them has widened: world corn stocks were cut 2.6 to 272.1 million tonnes while wheat stocks were raised 3.0 to 276.3. Less room on corn, more on wheat.
- September WASDE: world corn stocks 272.1 million tonnes, down 2.6; production 1,291 against use 1,320.
- World wheat stocks raised 3.0 to 276.3 million tonnes, mainly Russia, Australia and Ukraine.
- Russian and Ukrainian wheat exports cut again on weak August Black Sea shipments.
UK relevance: A thinner global grain margin leaves UK food import prices more exposed to the next shock.

- Coceral cut the EU-plus-UK maize crop to 48.6 million tonnes from 52.7; France 7.6.
- MARS: EU grain maize yield 6.50 t/ha, down 2% on the month, 8% below average.
- USDA nudged EU corn up 0.4 to 50.6 million tonnes — the one forecast to rise.
