Corn is hugely popular cereal, with a global market of 1 billion metric tons per year. The U.S. accounts for one-third of total production and 40 percent of global exports. In all, 60 percent of corn is used for animal feed, while the remainder is used for ethanol and food products.
As emerging countries eat more meat, the demand for corn is expected to increase. But with one-third of the global crop genetically modified, GMO restrictions in Europe and China could hurt the market. The future of biofuel policies in the U.S. is also uncertain.
