CHICAGO, Ill. (Reuters) – Crop prices surged last week as the U.S. Federal Reserve’s plan to buy $600 billion in government bonds drew investors to commodities and pushed the U.S. dollar down.
The move is aimed at keeping interest rates low and encouraging borrowing to stimulate economic growth.
“With the government putting more money in the system to lower interest rates, which lowers the value of the dollar, it’s the green light to buy commodities,” said grains analyst Don Roose of U.S. Commodities in West Des Moines, Iowa.
