These prices are from the Chicago Mercantile Exchange, a daily spot market for cheese. Until September 1, 1998, cheese trading took place once a week on Thursdays. The Chicago Merc replaced the National Cheese Exchange on May 1, 1997. Historically, the National Cheese Exchange was an important market for pricing 80 to 90 percent of the wholesale cheese in the U.S. Also, the NCE had a tremendous influence on-farm milk prices because of the great effect it has on the Basic Formula Price (BFP); the BFP is the foundation price for all prices under federal milk marketing orders.
