Brent fell below $90 a barrel on 10 November, the first time since 31 August, after President Trump said the war on Iran is "effectively over"1. For buying teams, the question is not where crude goes next. It is which cost lines are wired to it, and how long the wire is. Diesel surcharges follow within weeks. Bunker clauses follow at their next reset date. Resin, chemicals, container freight and risk charges do not follow until someone reopens the contract.

Brent fell nearly 3% to $89.66 after a near 6% drop the previous session1. Transport Topics put the fall at 3.1% to $89.672. In evening trade in India, January Brent was $90.22, down 2.54%, and WTI's December contract $85.07, down 2.06%9. Amrita Sen of Energy Aspects said the market has "erased it all" of the war risk premium3. This is a risk-premium unwind, not a supply recovery. Gulf crude exports are put at 80-85% of pre-war levels and refined product shipments at 35-40%10. The latest EIA spot reading was $107.03 on 3 November, still up 74.5% this year11.

Diesel and road fuel reprice first

The fastest line is road diesel. The US Department of Energy/EIA weekly retail average fell 16.5 cents a gallon to $6.127, effective Monday and published Tuesday, the second consecutive weekly decline3. That is the benchmark "used for most fuel surcharges"3. Ultra low sulphur diesel futures settled at $4.4216 a gallon on 1 November, $4.2148 on Monday and traded near $4.1409 on Tuesday morning3.

If your truckload contract carries a diesel index, the table moves on the published weekly number. A mid-November shipping week should already carry a lower surcharge than October. The same EIA series was $6.292 a gallon on 2 November, up 79.8% this year12. A 16.5 cent cut is real money, but small against the year's increase.

Bunker surcharges follow the calendar, not the news

Marine fuel has repriced faster than any other input. Rotterdam's HSFO, VLSFO and LSMGO fell by $28 to $133 a tonne, HSFO the most, and Singapore's grades by $25 to $1814. LNG as bunker fuel flipped from a $94 a tonne premium over LSMGO in Rotterdam to a $78 discount4. The 380-cst HSFO crack against Dubai went from a $5.34 a barrel premium to a $2.29 discount on 5 November, its lowest since mid-September13.

Your BAF will not move that fast unless the clause says so. Swire Shipping is raising its Emergency Bunker Surcharge to $535 per 20-foot and $1,070 per 40-foot container for bills of lading from 15 November. That sits on top of the prevailing first-quarter 2026 Bunker Adjustment Factor5. MSC's November FAK rates already include a Global Fuel Surcharge of $266 per TEU14. Ocean Network Express adds a 12% inland fuel surcharge on Kenyan rail cargo from 18 November, and 4 December for FMC trades15. Maersk cut its Italian intermodal fuel fee from 1 November16.

Direction for December and January resets is down, but November is set. Check the index and assessment date in your clause first.

Freight, air cargo and war risk stay priced for escalation

Container rates are easing, not collapsing. Drewry's World Container Index fell 1% to $4,389 per 40-foot container, and the Freightos Baltic Index fell 2% to $3,452, both a second weekly decline6. Even so, Asia to US West Coast spot rates in October were 343% above their 28 February level7. Average fuel surcharges on long-term contracts across four major Asia trades had risen 42% to $820 per FEU7. Deep sea freight producer prices were up 36.8% on the year in September17.

Air cargo is held up by peak demand more than fuel. Far East to North America rates rose 9% in a week to $7.76 per kg, up 40% on a year earlier18. US Gulf jet fuel spot was $4.198 a gallon on 3 November, still up 119.7% this year19.

Risk charges are stickier. MSC extended its $55 per TEU piracy surcharge and $36 per TEU Suez Canal surcharge to more Mediterranean and Black Sea ports from 15 November14. Iran's Revolutionary Guard claimed on 10 November that two tankers caught fire in the strait, a claim not independently verified20. Xeneta forecasts global spot rates could fall 30% in 2027 from third-quarter 2026 levels, with contract rates down 5%, but that is a forecast, not an invoice7.

Resins, chemicals and packaging lag by months

Polymer costs are the slowest to turn. US producer prices for plastics materials and resins were 327.5 in September, down 1.6% from August and up 5.9% on a year earlier, well below May's 3658. Industrial chemicals producer prices were 338.1, up 0.6% on the month and 13.8% on the year21. A monthly index cannot capture this week's move; producers price from feedstock booked weeks or months earlier.

The feedstock picture is better. The Gulf normally supplies more than half of Asia's naphtha imports, and Western loadings fell to 0.9 million tonnes in October as freight outran the East-West spread22. Cracker economics were thin already: the ethylene-naphtha spread slipped below its 2025 average, and benzene and paraxylene spreads sit near breakeven22. Producers have more room to hold resin prices than to cut them fast while rebuilding margins squeezed all year.

The base is still high. Polypropylene in India was ₹140 a kilogramme in September, up 41% on a year earlier. ABS rose 20% and polycarbonate 16%, and polymer prices across grades were up 16-41%23. Expect the Q1 2027 negotiation to be argued from September and October feedstock costs, not today's Brent.

What the earlier ceasefires showed

De-escalation headlines have not held this year. A ceasefire agreed on 8 April was to include reopening the strait, but it failed after the Islamabad talks24. A memorandum of understanding signed on 17 June was followed by Iran closing the strait again on 20 June, and the truce broke down on 8 July24.

Benchmarks can still reprice in days. The HSFO crack flipped to a discount within a week. Dirty tanker rates from Rotterdam to Singapore eased from a record of about $168 a tonne in mid-October to about $95 in early November13. Maersk cut its Emergency Contingency Surcharge from Middle East ports to West Africa by $500 per container from 1 November25. Traders are not convinced. "The market is still tight towards the year-end, and there should be some rebound. Freight is still expensive, which makes resupply costs expensive," a Singapore-based fuel oil trader said13.

Common questions

Will my diesel fuel surcharge fall in November?

If the clause points to the US DOE/EIA weekly retail average, it should, with a lag of one to two billing cycles. That number fell 16.5 cents to $6.127 a gallon in the week to 9 November3. If it points to a monthly index or a published tariff, the change lands at the next review, and some fuel-linked fees are still rising15.

When will resin and packaging prices come down?

Later than crude, and not automatically. Resin producer prices were still up 5.9% on the year in September and industrial chemicals up 13.8%8, 21. Naphtha supply is improving, but thin cracker margins give processors little reason to lead prices down22. Expect movement at Q1 2027 settlements, not in November.

Should I lock 2027 freight and BAF now?

Split the decision. First-quarter bunker surcharges will be set from December and January assessments, when the recent fall will be visible4, 5. Risk charges are different: piracy and canal surcharges are still being extended14. Fix the capacity you need, but keep the fuel line indexed.
