U.S. ethylene spot prices stayed flat last week, a sign of steady production and long market conditions that continue to define the Gulf Coast trade.
A U.S. industry source told that spot prices were unchanged as the region remained oversupplied. Downstream, export polyethylene prices kept sliding on soft demand and heavy inventories, but ethylene producers reported healthy margins that encouraged output and kept spot prices anchored despite rising export volumes.
By Friday, ethylene spot values were assessed at 20.00–20.50 cents per pound FD US Gulf, unchanged from the previous week. In Asia, CFR Northeast Asia prices eased to 840–850 USD per metric ton, down 5 USD week on week.
The U.S. ethylene contract price for August 2025 settled at 32.00 cents per pound, a drop of 0.50 cents from July, reflecting the persistent length in the market.
