Five points where the explanation changes.
Choose a case to put its monthly table, comparison chart and historical explanation together. Each case uses a different interval because the turning points differ.
| Period | What to notice | Read the case |
|---|---|---|
| 2021-01–2021-05 | resin prices outran oil | Open explanation |
| 2022-04–2022-08 | PP turned down while energy stayed expensive | Open explanation |
| 2022-12–2023-12 | engineering resins fell more than oil | Open explanation |
| 2024-01–2024-06 | butadiene strengthened with little net change in oil | Open explanation |
| 2025-06–2025-09 | TDI diverged as supply was disrupted | Open explanation |
Turn a price explanation into a cost review.
Start with the exact grade, supply route and contract period. Then separate three questions:
- Did the relevant input move? For PP, examine propylene before using crude. For ABS, examine its separate monomers. Match the supplier’s benchmark, grade, currency and averaging period.
- Did availability or demand change? A refinery can produce more propylene because fuel demand is strong. A shutdown can constrain an intermediate even when oil falls. Look for the actual event and its dates.
- Which part of the quotation should change? Review feedstock terms, energy adjustments and temporary supply premiums separately. A percentage change in one input is not the same percentage change in the whole resin or component price.
The missing link is the event between the input and the selling price. The same resin can be cost-led in one period and supply- or demand-led in another.
What this means for a forecast
Use the historical case to identify what could interrupt a cost trend. Falling oil plus available supply is a different scenario from falling oil plus an outage. To translate an input change into a purchase-price adjustment, use the applicable material quantities and the agreed contract terms.
Using these lessons for US purchasing
The method transfers; the price series do not become US quotations. US ethane-based PE and European naphtha-based PE can face different feedstock economics. Recheck the US grade, regional monomer, local supply, freight, currency and contract before applying an adjustment. EIA explains the differing feedstock and co-product routes in the sources below.
How to read the comparison
Each series starts at 100 in the first displayed month. An index of 120 means a 20% increase; 90 means a 10% decrease. Select “Change from start (%)” to see that movement directly.
These comparisons show relative movements, not prices per tonne. Different currencies, grades and regions can affect the comparison. Source links accompany each historical explanation.

2021: resin prices outran oil
Read PP against propylene (C3), then against oil. PP and PE increased faster than Brent over these months. The closest available PP input also rose, but less than PP. This is why an oil-only explanation misses part of the movement.

What happened in the market
LyondellBasell's 30 April 2021 results describe strong demand raising PE and PP spreads over monomers in its Europe, Asia and International segment. BASF's 2021 Materials review separately describes strong demand, limited availability and disruptions to production and raw-material supply.
LyondellBasell · Q1 2021 results · 30 Apr 2021 · BASF · Materials business review · FY2021
Why those lines can separate
When available polymer supply is tight, buyers compete for resin as well as paying for more expensive inputs. Polymer prices can therefore move more than upstream costs. These producer reports support that mechanism for the period; the PP–C3 percentage gap is not a measured producer margin.
What a buyer should do with this
An increase justified only by oil is incomplete here. Separate the relevant monomer adjustment from a temporary availability premium, and ask when that premium will be reviewed as supply recovers.
Reading this comparison
Producer reports describe wider market conditions. The effect on a particular grade depends on availability and purchasing terms.
2022: PP turned down while energy stayed expensive
Do not join December 2021 directly to August 2022 and skip the middle. PP reached a local high in April, then fell through June and August. Propylene also fell; PA6 held much closer to its April level. European gas rose sharply over the same interval.

What happened in the market
LyondellBasell's Q3 2022 results report high European energy costs alongside weak demand and lower operating rates. In its retrospective 2022 review, UK distributor Plastribution describes strong transport-fuel demand supporting refinery runs, producing more propylene relative to petrochemical demand. It also describes weaker demand and renewed import availability for polymers.
LyondellBasell · Q3 2022 results · 28 Oct 2022 · Plastribution · Review of 2022 & outlook for 2023
Why those lines can separate
Two forces can run in opposite directions: energy raises production costs, while weak resin demand and plentiful feedstock or imports reduce selling-price pressure. Refinery propylene is a co-product of fuel production; its supply can increase because fuel is profitable, even when PP demand is weak. PP itself is deliberately polymerised, and other propylene routes also exist.
What a buyer should do with this
An energy surcharge does not establish that the whole PP price must rise. Review the direct-input benchmark and polymer market separately. Keep energy terms, monomer terms and any temporary premium identifiable so each can be reset against its own evidence.
Reading this comparison
The refinery account is retrospective and discusses spot propylene. Price bases and contract timing can differ; the PA6 comparison does not establish why its price held up.
2023: engineering resins fell more than oil
Brent changed relatively little between these December endpoints, while PA6, PA66 and PC declined much more. June matters: the path was not a single uniform annual move. Compare each resin's monthly rows before assuming one oil adjustment explains them all.

What happened in the market
BASF's 2023 Materials review attributes lower selling prices to very weak demand and lower raw-material prices. It identifies falling prices in polyamide value chains and lower volumes, especially in Europe.
BASF · Materials business review · FY2023
Why those lines can separate
A market price can fall through both reduced input pressure and reduced pricing power. A higher historical resin price is not necessarily a permanent cost floor. The BASF evidence supports this combined explanation at business level; it does not isolate a demand coefficient or prove the exact cause of the PC series.
What a buyer should do with this
Review crisis-era premiums and the current direct-input basis separately. A small oil decline does not by itself rule out a larger resin-price review. Compare alternative qualified supply and contract reset terms before quantifying the adjustment.
Reading this comparison
Annual producer reports describe broader market conditions. They do not quantify how much each factor contributed to an individual monthly price movement.
2024: butadiene strengthened with little net change in oil

What happened in the market
Argus's public 10 May 2024 sample reports European butadiene supply constrained by outages, with spot enquiries holding firm. EIA's cracking explanation shows why feedstock choice changes the mix of ethylene and co-products, including butadiene.
Argus Butadiene · public sample · 10 May 2024, p. 6 · EIA · Ethane and naphtha cracking · 6 Apr 2022 · INEOS · ABS composition and manufacturing
Why those lines can separate
The amount of butadiene available depends on upstream operating conditions and the product mix, as well as demand from its own users. An outage can constrain supply even without a comparable rise in oil. The May report documents a relevant tightness episode within this interval; it does not explain the entire January–June increase.
What a buyer should do with this
For an ABS discussion, inspect butadiene, styrene and acrylonitrile separately and use the grade's agreed cost basis. Do not apply butadiene's full percentage increase to the entire ABS price. Recovery costs and joint-production economics still matter; a co-product is not free.
Reading this comparison
The May report documents a supply constraint within this interval, not the cause of the entire six-month increase. Butadiene is one component of ABS, not the whole material cost.
2025: TDI diverged as supply was disrupted
Follow the sequence: TDI fell from June to July, then jumped in August and again in September. Brent, MDI and polyols did not share that jump. Using December-to-September alone hides when this break actually happened.

What happened in the market
Covestro's half-year report records a fire at an external Dormagen substation on 12 July 2025. The resulting power failure affected chlorine and TDI production, among other operations. The company declared force majeure for deliveries of the relevant product groups from the site.
Covestro · Half-year report · 31 Jul 2025, note 11
Why those lines can separate
This is a documented supply interruption in the same region and just before the August–September TDI rise. It supports a supply-risk explanation rather than an oil-cost-only explanation. The event also affected other products: different inventory, alternative supply and customer demand can transmit one event differently across markets. Those buffers are not measured here.
What a buyer should do with this
A temporary availability problem calls for supply continuity and a dated review of any surcharge, not a permanent oil-linked cost increase. Ask for the affected plant, allocated volume and recovery evidence. Do not transfer the TDI increase to the entire polyurethane system: polyols moved differently.
Reading this comparison
The confirmed outage supports a supply-risk explanation but does not quantify its share of the price increase. July includes days before and after the fire. TDI, MDI and polyols are inputs to polyurethane, not finished polyurethane prices.
