GDT Event auctions are held twice a month, trading dairy commodity ingredients. To find out how the bidding works, take a look at GDT’s frequently asked questions. This page provides key results from the latest event:

  • Change in GDT Price Indices – these are weighted averages of the % change in prices between auctions. They give a more accurate reflection of price movements than using simple weighted average prices. More information can be found on the GDT website.
  • Average prices – the weighted average winning prices in US dollars per tonne.
  • Quantity sold – the total quantity sold in a Trading Event across all products, contract periods and sellers.

Six contract periods are made available, corresponding to future delivery periods. To download additional data for the contract periods, click here.

 “n.a.” indicates no quantity was offered or sold in either the current event and/or in the prior two events or that the prices published for individual products within a group were insufficient for the Price Index to be calculated
