European Standard Thermoplastic Prices Plunge as Oversupply and Weak Demand Drive Alarming €-30/tonne Drops Across Polyolefins and Styrenics 22-10-2025
Across the European thermoplastics market the outlook has turned decidedly negative. According to recent industry reports, standard thermoplastic prices have continued to fall over the last two months amid weak demand, a developing oversupply situation across most classes, and an inflow of aggressively-priced imported material. sustainableplastics.com+1
In the case of the polyolefins: during September and the first half of October, polyethylene (PE) prices fell by a combined total of approximately €20-30/tonne, even though the ethylene contract price largely held steady. Similarly, polypropylene (PP) has followed a like pattern, with prices down around €25-30/tonne despite an unchanged propylene contract. The pressure comes from large volumes of competitive imports, elevated inventories among distributors, and ongoing softness in demand.
Turning to the styrenic family: polystyrene (PS) prices have fallen in each of the last seven months, reaching their lowest level since summer 2023. This roughly aligns with a decline of €46/tonne in the September styrene monomer reference price, and a further €41/tonne drop in October. The downward trend underscores how manufacturers are passing monomer cost reductions (and then some) to maintain sales.
Meanwhile, the PVC sector remains stable—prices have effectively held flat for the past four months, amid weak demand and abundant supply. Yet this stability may reflect lack of upside rather than strength.
Finally, in the PET market, weakness is acute: prices fell by about €40/tonne in September due to very low demand, and early October saw even stronger downward pressure on European PET.
Why this matters for industry players:
-
For polymers converters and compounders, falling Thermoplastic Prices may help input costs, but only if demand recovers; with weak orders and high inventories, margin improvement seems distant.
-
For producers, the erosion of Thermoplastic Prices despite no major feedstock cost increases signals shrinking margins and likely capacity rationalisation ahead. Indeed, imported material at aggressive pricing is squeezing European operations hard.
-
For buyers (packaging, automotive, consumer goods), lower Thermoplastic Prices might seem a relief—but they also reflect deeper health issues in demand and may presage further uncertainty in supply and supplier stability.
What to watch in the coming months:
-
Whether demand shows any meaningful uplift (e.g., from end-applications) to absorb the oversupply. Currently many converters are reluctant to build stocks, delaying orders even further. plasticportal.eu+1
-
Whether imports continue at the same pace and at what pricing — many European producers cite imports as a major pressure point.
-
Whether feedstock or monomer contract prices begin to rise, which might enable producers to attempt price recovery—but given weak demand the pass-through may be limited.
In conclusion: the downward move in standard thermoplastic prices across Europe is a clear signal of stress in the supply-demand balance. While lower prices might offer short-term relief to buyers, the underlying oversupply, import competition and weak demand suggest a challenging environment ahead for the value chain—from producers to converters.
