Part of the reasons we are shitting. First chart is basket of commodities since 1992. Farm prices and all commodity prices have been on a tear since then, almost seven years of prices not seen ever in the history of the world. You can see that prices have fallen slightly lately. BUT if you check the chart at the bottom which just show prices since July 1st you might think that the bottom has fallen out of the market. It ain't true. Prices are still at historical highs
