The IEA sharply lowered its 2026 global oil demand outlook, citing the escalating Mideast conflict and elevated energy prices. The agency now projects a significantly steeper year-on-year decline in consumption than previously forecast, warning that market tightening and demand destruction are accelerating.
Trinseo has restarted the sale of its 50% stake in the Americas Styrenics joint venture with Chevron Phillips Chemical, which produces styrene and polystyrene, following Trinseo's bankruptcy declaration earlier this year. The ownership uncertainty at one of the key styrene and polystyrene production platforms introduces supply risk for those commodity chemicals, likely supporting firmer pricing as market participants assess potential output disruptions.
In 2025, the 1-Decene market showed a generally soft and cautious trend throughout the year, closely tied to movements in its key feedstocks and downstream demand. In the first half of the year, oversupply and weak buying from industries such as coatings, automotive, and plastics put downward pressure on prices. Early-year demand softened after seasonal holidays, and many buyers delayed purchases, while stable production and sufficient inventories kept the market well-supplied.
During the third quarter, the market saw slight fluctuations. Planned maintenance at several production plants temporarily tightened supply, causing short price gains. However, these were offset by fresh shipments from other regions and growing stock levels at major ports, which reinforced oversupply. Industrial activity remained moderate, and seasonal factors such as summer slowdowns in Asia further weakened purchasing interest. By the end of the quarter, prices stabilized at lower levels, reflecting continued cautious sentiment.
In the fourth quarter, the 1-Decene market remained soft with minor periods of stability. Early in the quarter, weak demand and comfortable supply forced sellers to offer discounts. Later, slight reductions in production and lower inventories provided temporary support, but subdued activity from downstream sectors prevented any strong price recovery. Overall, the market maintained a mild downward to stable trajectory.

In 2024, the 1-Decene market showed varying price trends across different regions. In Asia, particularly in China and India, prices moved upward during most of the year. Rising costs of upstream feedstocks and limited supply from key producers created pressure on the market. Strong demand from downstream industries, such as chemicals and specialty polymers, supported the price growth. Production levels gradually increased after seasonal slowdowns, but logistical challenges and tight supply in some areas kept the market relatively firm. Overall, the Asian market saw steady upward movement with occasional short-term fluctuations.
In Europe, prices showed a mixed trend. Early in the year, high input costs and low manufacturing activity limited supply, which kept prices elevated. However, weaker demand from end-use sectors, combined with cautious purchasing by manufacturers, moderated the upward pressure. Some countries experienced small price gains due to stronger local demand, while others saw flat or slightly lower pricing. The overall European market remained balanced, with supply sufficient to prevent sharp increases.
In North America, the market was more stable. Moderate demand from downstream chemical and industrial sectors, along with steady production and adequate feedstock supply, kept prices mostly unchanged. Minor fluctuations occurred due to occasional feedstock cost changes and economic uncertainty, but the market maintained overall stability.

1-Decene is obtained from oligomerisation of ethylene with the help of triethylaluminum catalyst. This results in the formation of alpha-olefin mixture, which finally undergoes fractional distillation to produce 1-Decene.
