CHICAGO, Aug 18 (Reuters) – U.S. wheat futures slid 1.5 percent on Monday, giving back some of the strong gains made in the previous two sessions, as fears of potential supply disruptions from the Black Sea region eased.
New-crop corn and soybeans dipped were little changed as traders awaited results from an annual U.S. crop tour.
Tensions between Russia and Ukraine influence the grain markets because the countries are major exporters of wheat and corn. Their conflict was viewed as less heated following talks among Russia, Germany, France and Ukraine on Sunday.
“We went home Friday thinking the Ukrainians and Russians would be at each other’s throats today,” said Jim Gerlach, president of A/C Trading. “It looks like they de-escalated a bit over the weekend.”
Russia said all objections to it sending a humanitarian convoy to Ukraine had been resolved, but no progress was made toward a ceasefire between government and rebel forces in the east of the country.
Chicago Board of Trade December wheat lost 1.5 percent to $5.55 a bushel by 10:10 a.m. CDT (1510 GMT), after climbing more than 4 percent in the previous two sessions.
December corn dropped 0.6 percent to $3.74-3/4 a bushel after rising on Friday to a nearly one-month high of $3.79-3/4 a bushel. November soybeans slipped 0.1 percent to $10.51-1/2 a bushel.
U.S. rains reduced concerns about dry crops areas, weighing on the corn and soy markets, Gerlach said.
A private U.S. crop tour this week is expected to find corn and soy yields are higher than the U.S. Department of Agriculture estimated in a crop report last week. About 130 crop scouts will participate in the Pro Farmer Midwest Crop Tour, which began surveying fields on Monday.
Expectations for record-large harvests should pressure prices, after corn futures last week posted their biggest weekly gain in five months.
“Ultimately this little bounce we had it going to fizzle out,” Gerlach said.
