Richard Allen, president global ingredients at Fonterra, said the strong sale may have signalled a return to more normal inventory levels by customers.
“We are seeing continued good, strong dairy demand out there in the world,” Allen told NZME’s The Country radio show.
“China seems to be back in the market and there has been good participation across South East Asia and the Middle East as well,” he said.
“There is still a lot of milk around and we have continued to see good milk production in New Zealand – up 2.5% in the 12 months to December – and the US and Europe are both up as well.
“What we are seeing is that dairy does have a tendency to overreact and coming off a period of high prices, a lot of players were probably running inventory pretty low.”
Prices slumped going into the end of last year but have been firming so far this year.
“Prices got to a point where it was pretty enticing and I think what we are seeing now is a correction back to normal inventory levels.”
NZX Dairy’s head of dairy insights, Cristina Alvarado, said the scale of today’s move “materially exceeded” market expectations.
She said it reflected a combination of seasonally tightening supply from New Zealand, concentrated regional demand and constrained availability across several key commodities, rather than a sudden shift in global milk production trends.
“While milk output has continued to track higher year-on-year across the major exporting regions, this event highlighted that near-term product availability and demand dynamics remain the dominant pricing drivers,” Alvarado said.
New Zealand is moving toward the lower end of the 2026 milking season, and sharply reduced Fonterra offer volumes across wholemilk powder, skim milk powder and butter had heightened buyer urgency.
Protein markets led the upside, driven primarily by global supply constraints rather than changes in milk flows.
In the United States, strong cheese margins have continued to divert milk away from powder production, tightening non-fat dry milk availability and supporting higher domestic prices.
“That tightness has increasingly flowed into international markets, lifting global skim milk powder sentiment,” Alvarado said.
North Asia accounted for 42% of total purchases at this morning’s auction, up from 40% at the prior event, while European buying increased materially.
“Overall, the event reinforces that while global milk production trends shape the medium-term outlook, short-term GDT pricing continues to be driven by seasonal supply dynamics, regional demand concentration and limited substitution across origins,” Alvarado said.
“With New Zealand volumes set to decline further into autumn, near-term price support is likely to persist, particularly for proteins and milk fats.”
In December, Fonterra adjusted its milk price forecast range from $9.00-$10.00 per kg of milksolids (kgMS) to $8.50-$9.50/kgMS – the midpoint changing from $9.50/kgMS to $9.00/kgMS – in response to strong milk flows.
GlobalDairyTrade Holdings is owned and managed as a strategic partnership between the European Energy Exchange (EEX), Fonterra and NZX, with equal one-third shareholdings.
