The Commodity Research Bureau's spot commodity price index rose 2.1 percent month over month in April 2014 but continues to be well below its April 2011 peak of 575.7. Contributing to the rise were increases in both major index subdivisions, raw industrial materials (such as burlap, copper scrap, cotton, hides, lead scrap, print cloth, rosin, rubber, steel scrap, tallow, tin, wool tops, and zinc) and foodstuffs (such as butter, cocoa beans, corn, cottonseed oil, hogs, lard, steers, sugar, and wheat).
