Fonterra has cut its farmgate milk price to $6.40/kg of milksolids from its previous forecast of $6.75/kg.
The cut was announced to the Australian stock exchange late last night.
Fonterra chairman John Wilson said the fall in the New Zealand dollar had partly offset the steep decline in Global Dairy Trade prices but said a cut in the forecast was a prudent step.
The GlobalDairyTrade price index rose 0.4 per cent in this week's auction, after four consecutive declines, although the gain came on lower volumes sold.
Fonterra's revised forecast still sits above DairyNZ's latest estimate of breakeven, of $5.20-$5.25/kg, and compares with last year's price of $6.12/kg. Wilson said the cut reflected ongoing volatility in global dairy prices and cited a 10 per cent drop in the price of whole milk powder since August 1.
"What is driving this forecast is that despite demand for dairy remaining strong, particularly in China, other parts of Asia and Latin America, we are seeing strong production out of Europe and continued high levels of EU intervention stockpiles of skim milk powder," he said.
