The GDT Price Index rose 2.2% at the first auction of 2018, led by a 4.2% gain in whole milk powder prices. Fonterra cut its 2017-18 NZ milk intake forecast by about 4% due to dry pasture conditions and reduced WMP volumes offered for sale.
Dry conditions reducing New Zealand milk supply tighten global powder availability and lift export prices. The gain was smaller than the 6% some traders expected, so the rally may be limited.
After 32 past bullish weather events, Milk (Class III) moved a median +0.1% over 5 sessions (50% higher; middle half -0.7% to +3.4%), and +3.2% over 20.
