The wheat market barely rippled when Russia recently threatened to exit a grain export deal with Turkey, the United Nations and Ukraine, grain analysts say. The agreement allows food shipments from three Black Sea ports. Chicago wheat futures opened 12 to 15 cents higher on Sunday evening and fell 5 cents before settling at 4 cents up at closing, said Byron Behne, senior grain merchant for Northwest Grain Growers in Walla Walla, Wash. Soft white wheat ranged from $7.45 to $7.70 per bushel on the Portland market. "When they complain about this stuff, it used to give us bigger rallies, but ever since November, the first time the deal was renewed ... every time they complain about the deal, the reaction has been smaller than it was prior to that first big renewal,” Behne said.
