Chicago | Reuters — U.S. wheat futures rose more than one per cent on Wednesday as signs of a hardening conflict between Ukraine and Russia and worries about dryness in China appeared to spark a round of short-covering, analysts said.
Corn and soybean futures also moved higher on bargain buying after the benchmark Chicago Board of Trade corn contract hit a multi-month low and soybeans touched a seven-week low earlier this week.
A setback in the dollar lent support, in theory making U.S. grains more attractive to those holding other currencies.
