据ICIS网站2月5日休斯顿报道 由于原料价格下降和新产能的涌入，美国1月乙烯合同下跌1.25美分/磅（28美元/吨）。

结算结果显示，1月乙烯合约为25.75美分/磅，低于12月份的27.00美分/磅。

1月份，现货价格小幅上涨，从12月份的15.75-21.50美分/磅略微上涨至16.00-21.50美分/磅。

今年开始，生产问题暂时阻碍了乙烯市场的发展。这些短期供应限制减轻了新Formosa Plastics Corp USA裂解厂的额外供应和下游聚乙烯（PE）工厂延迟开工造成的低于预期需求所带来的价格下行压力。

美国乙烯合同价格通常在月初结算。

乙烯是重要的石油化工原料，用于生产聚乙烯（PE）、乙二醇（EG）、聚氯乙烯（PVC）等产品。

美国主要乙烯生产商包括埃克森美孚、英力士、利安德巴塞尔和壳牌化学。

美国主要买家包括西方化工和西湖化工。

US January ethylene contracts settle at decrease

US January ethylene contracts have settled for a majority of participants at a decrease of 1.25 cents/lb ($28/tonne) amid lower feedstock prices and an influx of new capacity.

The settlement puts January ethylene contracts at 25.75 cents/lb, down from 27.00 cents/lb in December.

Spot prices increased slightly during January, trading at 16.00-21.50 cents/lb from 15.75-21.50 cents/lb in December.

Production issues have temporarily backwardated the ethylene market to start the year. These short-term supply constraints have mitigated downward price pressure exerted by additional supply from the new Formosa Plastics Corp USA cracker and less-than-expected demand due to delayed start-ups of downstream polyethylene (PE) plants.

US ethylene contract prices typically settle at the start of the month.

Ethylene is a key petrochemical feedstock, used to make polyethylene (PE), ethylene glycol (EG) and polyvinyl chloride (PVC) among other products.

Major US ethylene producers include ExxonMobil, INEOS, LyondellBasell and Shell Chemical.

Major US buyers include Occidental Chemical and Westlake Chemical.
