Butter prices set a record high of $US5631 per metric tonne in this week's
GlobalDairyTrade auction, reinforcing the increasing demand for milk fats.
Overall dairy prices lifted 0.6%, although key product whole milk powder fell 2.9% as expected. Anhydrous milk fat (AMF) prices also retreated from an auction record high, falling 1.2%.
A surge in global demand for milk fats could largely be attributed to an acknowledgement by the scientific community that fats were no longer as bad for health as once feared, ASB senior rural economist Nathan Penny said.
The trend back to fats, along with tighter global supply, had sent milk fat prices soaring, with both butter and AMF setting a number of auction record highs this year.
That trend was expected to continue and, while global dairy supply was likely to lift this season, global demand was likely to match that lift.
