Dairy product prices had the biggest drop in almost 20 months at Fonterra's latest GlobalDairyTrade auction as whole milk powder fell to its lowest level in more than a year.
The GDT price index dropped 8.9 per cent to US$4,124 a tonne from US$4,563 per tonne two weeks ago, the fourth straight decline and the lowest since August 2012. Some 39,653 tonnes of product was sold, up from 39,008 tonnes two weeks ago.
Soaring prices of global dairy products helped Fonterra lift sales in its first half by 21 per cent, including record shipments to China in December, although profit tumbled 53 per cent as the high price of milk, which is based on reference products including milk powder, drove up its input costs for products such as casein and cheese.
The company said last month it sees no let-up in the second half because factory constraints have led to an unfavourable product mix.
