USDA released the advanced prices for September.   The NAS prices for butter was up 2.7%, NFDM and Cheese were up 4%  whey up 10%.

Class I – $18.30/cwt up 4%
Butter fat – $2.61/lb up 3%

Overall, everything looks up  5-10%

One of the things that we need to remember is that there is significant lag in prices.  For example, the Class I price for September is already set.  Consequently, things like tariff deals take a long time to result in price changes.
