Corn and wheat futures rise amid speculation of buying interest

Corn and wheat futures rose in Chicago amid speculation of buying interest from animal-feed makers and investors after grain prices fell to four-year lows this week.

Corn futures have slumped 25% in the past 12 months while wheat fell 19% amid expectations for bumper crops to boost supply.

World grain stocks will rise to a 15-year high by the end of the 2014 to 2015 season as production of both crops outpaces demand, the International Grains Council forecasts.
