據ICIS網站6月3日消息 東北亞乙烯和丙烯價格的反彈以及歐洲5月苯合約價格的大幅上漲幫助穩定了本月全球ICIS石化指數（IPEX）。

然而，與2019年5月相比，區域和全球指數仍大幅下降，因為世界大部分地區繼續遭受冠狀病毒大流行期間封鎖帶來的負面經濟影響。

中國乙烯需求強勁，而6月份的貨物供應緊張。受原油價格上漲的影響，中國下游市場表現較好，石腦油成本上升，從而推動了市場動態。

在歐洲，5月苯合約對原油價格上漲做出了反應。

ICIS石化指數追蹤了12種主要石化產品和聚合物的變化情況：乙烯、丙烯、丁二烯、苯、甲苯、對二甲苯（PX）、聚乙烯（PE）、聚丙烯（PP）、苯乙烯、聚苯乙烯（PS）、甲醇和聚氯乙烯（PVC），區域指數按產能加權。

指數值隨著每月合同價格的商定而變化。東北亞對二甲苯2020年5月的合同價格尚未確定。

May Global IPEX flat from April but 37% lower year on year

A rebound in ethylene and propylene prices in northeast Asia and the much higher Europe May benzene contract price helped stabilise the global ICIS Petrochemical Index (IPEX) for the month.

The regional and global index values, however, remain sharply down compared to May 2019 as large parts of the world continue to suffer from the negative economic impact of lockdowns in the midst of the coranavirus pandemic.

Ethylene demand is stronger in China while supply has been tight for June cargoes. Downstream markets in China are performing better and higher naphtha costs, on the back of the rising crude oil price, helped drive market dynamics.

In Europe, the May benzene contract reacted to the upward push in crude.

The ICIS petrochemical index tracks the movement of 12 major petrochemicals and polymers: ethylene, propylene, butadiene, benzene, toluene, paraxylene (PX), polyethylene (PE), polypropylene (PP), styrene, polystyrene (PS), methanol and polyvinyl chloride (PVC) with the regional indexes weighted by capacity.

Index values are subject to change as monthly contract prices are agreed. The northeast Asia paraxylene contract price for May 2020 has yet to settle.
