How does the GDT work?
GlobalDairyTrade trading events are conducted as ascending-price clock auctions run over several bidding rounds. In each auction a specified maximum quantity of each product is offered for sale at a pre-announced starting price. Bidders bid the quantity of each product that they wish to purchase at the announced price. If the price of a product increases between rounds, to ensure their desired quantity a bidder must bid their desired quantity at the new, higher price. Generally, as the price of a product increases, the quantity of bids received for that product decreases. The trading event runs over several rounds with the prices increasing round to round until the quantity of bids received for each product on offer matches the quantity on offer for the product (as shown in the diagram below). Each trading event typically lasts approximately 2 hours.
Why are prices so high in NZ?
Fonterra is responsible for 30% of the world’s dairy exports with revenue exceeding NZ$20 billion and is New Zealand’s largest company. With New Zealand being one of the biggest producers you would expect prices for New Zealand consumers to be lower than what they are – a litre of fresh milk in Germany was selling for the equivalent of $1.51, compared to $2.37 in New Zealand.
Milk being inelastic in demand and is an essential part of the typical family shopping basket. Up until 1976 the price of milk was set by the government and producers were subsidised the loss that they incurred by a set price. The subsidy was completely removed in 1985 and by 1993, milk could be sold at any price. In January 1994, two litres was selling for the modern equivalent of $3.95. Consumer NZ estimates that for every $3.56 bottle of milk (an average retail price at present), about $1.19 would go to the farmer, $1.91 to the processor and retailer and 46c to GST.
Who gets what?
Because Fonterra take over 80% of what farmers produce it is difficult for the market to decide what an appropriate price to pay farmers. Therefore they work out what they believe is the highest sustainable price it can pay its farmers. It looks at the global dairy trade auction price and operating costs and capital costs to determine the farm gate price.
GDT price – Operating Costs – Capital Costs = Farm Gate Price
So farmers in New Zealand are at the mercy of the global market not how much is demanded in NZ supermarkets.
NZ Supermarket Prices
Supermarkets buy their milk from local distributors, either direct from Fonterra or other processors such as Synlait, or from suppliers who had value along the way. They then add their own costs to give a final price to the consumer but New Zealand food retailing effectively is a duopoly. Milk in Germany is much lower in price because of the high levels of competition with multiple chains operating there. In New Zealand however the price consumers pay reflects the concentrated nature of the market. Domestic milk market is dominated by one big supplier, Fonterra (see graph below), and two big supermarket chains – Foodstuffs and Progressive Enterprises – which means there’s little competition for your dairy dollar.
