HOUSTON (ICIS)--Asian ethylene margins fell during the week ended 21 July as feedstock cost increases outweighed higher spot ethylene values, the ICIS margin report showed on Monday.
Naphtha-based ethylene margins in Southeast Asia fell by 12% during the week, while LPG-based ethylene margins fell by 11%.
In Northeast Asia, naphtha-based ethylene margins fell by 9.7% and LPG-based ethylene margins fell by 7.5%.
On an ethylene production basis, naphtha costs rose slightly by more than $91-92/tonne during the week, while LPG costs rose by $66-67/tonne.
This outweighed an increase of $22/tonne in spot ethylene values in both NE Asia and SE Asia.
Cracker co-product credit values also rose, but increases were small relative to feedstock cost increases.
