"While Chinese demand has been solid, it hasn't been spectacular," he said. Other Asian and Middle Eastern buyers have stepped in, but have struggled to absorb the higher GDT supply, Williams said.
The market also appears to be banking on a rebound in New Zealand supply - despite the poor weather, he said. While pasture conditions remain "very sodden" in the North Island they are generally better in the South Island, Williams said.
Also "last year's poor performance through the seasonal peak for milk production would appear difficult to repeat," he said. Softer New Zealand production could still see a milk price of $6.75/kgMS, "but if not, it seems something around the mid-$6/kgMS is more likely."
ASB Bank chief economist Nick Tuffley was more optimistic about prices and said "overall we are expecting production growth to be held back by the bad weather we have been experiencing. We expect to see that eventually translate into the auction prices over time," he said.
ASB has expected production to increase 4 per cent versus the prior season and is now tipping a 2 per cent increase "with a question mark over that if we don't see weather conditions improve," he said.
Regarding the discrepancy between the futures market and the outcome, Tuffley said it was in line with recent results and "within the volatility we see from one auction to the next." ASB is still expecting Fonterra to pay $6.75/kgMS.
