Wheat prices advanced on concern that dry weather conditions in the United States plains region will harm this year's crop. The grain recorded its biggest weekly advance since last year's drought.
The price of wheat has been recovering this week following a sell-off that began in early December. This year's crop in the US may be hurt by a lack of rain in the Great Plains region and dry weather in Australia, where it is now summer, may also damage the harvest there.
"There's a continued dry situation in the southern plains that's not going away, so our winter wheat crop is being threatened," said Darin Newsom, a senior analyst at DTN. "As we start off the year, the first one up to bat is Australia and their crop could be suffering a bit from the heat."
