Ethylene prices continue to be high in the spot ethylene market because of three ongoing cracker shutdowns and one scheduled shutdown at the end of October. At the beginning of this week, front-month Williams System ethylene traded at 74 cents/lb ($1,631/tonne) and then 75 cents/lb, up from a trade at 73 cents/lb the previous day.
US spot ethylene prices hit a 29-month high on Tuesday on the back of two trades, tracking continued tight supply and low inventory levels.
