Dairy product prices increased at the Global Dairy Trade auction, gaining for the eighth time in nine auctions, amid expectations for decreasing supply.

The GDT price index rose 3.5 per cent to US$3,622, up from US$3,519 at the previous auction three weeks ago. Some 22,472 tonnes of product was sold, down from 23,902 tonnes at the previous auction.

Whole milk powder climbed 4.9 per cent to US$3,593 a tonne.

"The lifts in dairy commodity prices ... were closely aligned with market expectations," AgriHQ dairy analyst Susan Kilsby said in a note.


The price differential between whole milk powder and skim milk powder continues to widen, Kilsby noted.

"This is likely to encourage more milk to be diverted into WMP production although the low priced SMP is partially offset by the strength of the milkfat products which continue to trade well across the globe," according to Kilsby.

At the latest GDT auction, lactose rallied 10.6 per cent to US$873 a tonne, while anhydrous milk fat rose 2.9 percent to US$5,500 a tonne.

Rennet casein gained 2.3 per cent to US$6,201 a tonne, while cheddar added 2.2 per cent to US$3,752 a tonne.

Butter rose 1.7 per cent to US$4,262 a tonne, and skim milk powder advanced 1.4 per cent to US$2,570 a tonne.

"Skim milk powder price lifts are curbed by the large volumes ... in storage," Kilsby noted. "The EU is now releasing some of the older product is has stored which doesn't directly impact the current market for fresh product but it does imply that the European Commission is likely to release additional product next year so long as prices remain firm."

Bucking the trend, butter milk powder fell 2.6 per cent to US$2,408 a tonne.

The New Zealand dollar last traded at 71.10 US cents at about 12.09pm in New York, compared with 71.41 US cents at 5pm in Wellington the previous day.
