据石化产品新闻2021年3月5日新加坡报道，随着乙烯价格也飙升至两年高点，紧张的乙烯供应和强劲的下游市场导致了亚洲的乙烯-石脑油价差达到两年来高点。
统计数据显示，3月4日亚洲市场收盘时，CFR东北亚乙烯和CFR日本石脑油之间的价差为589美元/吨，在两周内大幅上涨了113.89%，创下两年来的新高。这个价差上次上涨是在2019年3月4日，为595.375美元/吨。
市场消息人士称，非一体化生产商的典型保本价差为350美元/吨，而一体化生产商的保本价差为250美元/吨。自2020年5月12日以来，乙烯-石脑油价差一直高于每吨250美元。
亚洲乙烯价格目前受到本地和深海货物供应紧张的支撑，韩国现货乙烯出口受到复苏的限制，其供应主要在国内消费。由于最近的冰冻天气，美国乙烯产量下降也影响到了亚洲乙烯市场，美国对亚洲的长期供应短缺导致现货市场的额外需求。
由于供应短缺，3月4日东北亚乙烯CFR估价为1180美元/吨，为两年高点。这个价格上一次上涨是在2019年2月27日，达到1190美元/吨。

Asia's ethylene-naphtha spread doubles in two weeks to reach two-year high
Tight ethylene supply and strong downstream markets have driven the key ethylene-naphtha spread to a two-year high, as ethylene prices also surge to two-year highs.
The spread between CFR Northeast Asia ethylene and CFR Japan naphtha physical was $589/mt at the March 4 Asian market close, up a sharp 113.89% in two weeks and a two-year high, data showed. The spread was last higher on March 4, 2019 at $595.375/mt, data showed.
The typical breakeven spread for non-integrated producers is $350/mt and for integrated producers is $250/mt, market sources said. The ethylene-naphtha spread has been above the $250/mt mark since May 12, 2020, data showed.
Asian ethylene prices are currently being supported by tight supply of both local and deepsea cargoes, with South Korea's spot exports limited due to turnarounds and its supplies being largely consumed domestically. The impact of US production lost due to recent freezing weather has also reached the Asian ethylene market, with the shortfall of US term supplies to Asia leading to extra demand in the spot market.
With supply short, CFR Northeast Asia ethylene was assessed at $1,180/mt March 4, a two-year high, data showed. The price was last higher on Feb. 27, 2019, at $1,190/mt, data showed.
