Reuters reports on May 17, 2018 that CBOT wheat rose about 1.9% to $5.03-3/4 and Kansas HRW wheat rose 2.3%, after weather concerns returned over US Plains drought, dryness in Australia and Russia, and rain delays to US planting. Soybeans steadied after a near two-week low on Chinese demand fears, and corn ticked up.
Drought in major wheat exporters tightens global wheat supply and supports feed wheat substitution costs. Soybeans stay pressured by trade-related demand uncertainty, limiting protein price gains.
