"Milkfat prices have posted new records in recent months with insatiable demand in developed markets and softer European milk supply limiting their export volumes," Williams said. "Seasonality has ensured tight Australasian supply too and Asian demand from a range of sources (especially foodservice/bakery) has driven tradable milkfat prices to new highs."
The New Zealand dollar index, which adjusts for currency movements, dropped 2.1 per cent to 210.8 in the month though it was up 18 per cent from a year earlier.
Forestry increased 1 per cent in the month, though there were offsetting movements at the sub-component level, with log prices up 2.2 per cent in July while wood pulp prices fell 1.9 per cent.
"Log prices continue to be supported by Chinese demand with port-level inventory and offtake continuing to track favourably," Williams said. "The Chinese government has also announced lower import tariffs on logs in a bid to curb the use of logs from their own native forests. Local demand has experienced the usual seasonal slowdown, but unpruned demand for structural timber and posts/poles remains strong."
Aluminium prices increased 1.2 per cent in July as markets remained focused on China's closure of spare capacity, while seafood was stable, with prices up 0.2 per cent, led by salmon.
