Meanwhile, Synlait's opening forecast for the upcoming season is $6/kgMS.
"We don't yet have a clear view of Covid-19's economic impact, but we do know it will impact demand, resulting in our decision to release a conservative opening forecast for the 2020/2021 season," Clement said.
The move follows Fonterra Cooperative Group, which last week said it expects to pay $7.10-to-$7.30/kgMS for the season ending May 31. It also adopted a wide forecast of $5.40-to-$6.90/kgMS for the upcoming season.
Fonterra chairman John Monaghan said it narrowed the range for the current season in response to softer demand relative to supply pushing down prices.
Looking out to next season, a global recession would reduce consumers' purchasing power, he said.
