Chicago | Reuters — U.S. wheat futures rallied to their highest in nearly nine years on Monday as ill-timed rains in Australia and rising Russian wheat prices stoked concerns about tightening supplies among the world’s top exporters.
Corn and soybeans followed wheat higher, with additional support from a waning U.S. harvest and strong domestic demand from ethanol makers and soy processors.
“The demand continues to equal or outstrip the supply in the short term,” said Don Roose, president of U.S. Commodities.
