Chicago | Reuters — U.S. winter wheat futures rose for the sixth day in a row on Wednesday as adverse weather in key exporting countries raised supply concerns, traders said.
Corn futures were steady to firm, with the front-month contract ending flat while new-crop offerings rose on support from dry soils that threatened to hamper crop development in the U.S. Midwest.
“Corn belt rain events are still basically non-existent in the two-week forecast,” Matt Zeller, director of market information at StoneX, said in a note to clients.
