The latest GDT result is "really positive" for Kiwi farmers says Rabobank Dairy Analyst Emma Higgins.
Prices went beyond market expectations, with the Global Dairy Trade price index rising by 3.7 per cent since the last auction.
"The fact that we've seen such strong prices, particularly for skim milk powder and Whole Milk Powder, the offers are at their peak, or nearing their peak, it's certainly very good for farmers and the farmgate milk price" Higgins told The Country's Andy Thompson.
Whole milk powder (WMP) prices, which have the greatest bearing on Fonterra's farmgate milk price, rose by 3.6 per cent to US$3254 a tonne.
Skim milk powder prices, which also have a strong influence on the milk price, rose by 6.7 per cent to US$2924 a tonne.
