Natural rubber closed the week at its highest level since 2013 adding fresh cost pressure for tire manufacturers. Separate developments in Europe, meanwhile, hinted at how road-transport demand could shift in the years ahead.
A 13-year high in rubber. The benchmark spot price reached 249.90 US¢/kg on 10 September, up 14.0% month-on-month and 43.4% year-on-year. Tightening supply in Indonesia and Thailand is a major driver. Elevated crude oil prices are adding to the pressure, making synthetic rubber less price-competitive against the natural alternative.
A possible ownership change further upstream. Saudi Aramco is reportedly working with an adviser on a sale of Arlanxeo, the Netherlands-based synthetic-rubber producer it has fully owned since 2018. The move is part of a wider divestment programme, with no formal process or timeline confirmed.
At the same time, developments on the demand side of the market broke in Europe this week. Unions FNV, CNV and VCP grounded Dutch public transport for 24 hours on 9 September. The strike halted NS trains, ProRail infrastructure work, and city and regional operators nationwide. The action protested planned €6.5 billion social-security cuts — only the Schiphol airport Sprinter kept running.
Separately, the European Parliament's Environment Committee voted 62-8 on 10 September to reject a Commission plan to loosen the ETS Market Stability Reserve, raising the allowance-invalidation threshold to 650 million from 2027 instead. That decision shapes future pricing under the incoming ETS2 road-fuel carbon market.
This week's major stories sit on opposite ends of the same market. Raw-material costs are climbing on the supply side. Meanwhile, transport disruption and carbon-pricing decisions shape how much Europeans drive — and how much rubber that ultimately requires.
