This commodities price chart shows how food prices have fallen or remained flat since early 2016, although non-food agriculturals have risen somewhat. Food prices have remained low due to a surplus of wheat and oil-seeds. The stocks-to-use ratio for wheat is at a nearly a 30-year high. Non-food agriculturals include timber, hides, wool, rubber, and cotton. Metals have led in commodity price growth in the past two years.
