US polyethylene buyers will continue to monitor spot availability, particularly for export, after industry data released last week showed gains in producer stocks for March. Export pricing moved mostly lower last week as sources pointed to increased availability for some grades, with the expectation that more could be coming before the end of the month. While pricing is coming more in line with levels needed for the export market, traders have noted additional declines were needed for some grades. In the domestic market, producers are again seeking a 3-cent increase in April after rolling the previously announced hike from March in the wake of contracts being heard settled flat. While domestic sales have been good, higher stocks and weaker feedstock ethylene prices were prompting some talk of rollover to potentially lower prices for April.
