By Rudy Ruitenberg April 7 (Bloomberg) -- Wheat, corn and soybeans declined in Chicago as a stronger dollar made U.S. supplies less attractive to investors and buyers holding other currencies. Wheat for July delivery fell 0.8 percent to $4.735 a bushel on the Chicago Board of Trade at 2:14 p.m. Paris time and May- delivery corn dropped 0.5 percent to $3.4475 a bushel. Soybeans for May delivery declined 0.2 percent to $9.4675 a bushel. The dollar strengthened for a second day against a basket of six currencies, rising to the highest level this month. “The generally stronger dollar has been sufficient to offset the greater demand arising from news of global economic strength,” economist Dennis Gartman wrote in his daily newsletter. Milling wheat for May delivery traded on NYSE Liffe in Paris rose 0.2 percent to 126.50 euros ($168.79) a metric ton, while November-delivery grain rose 0.2 percent to 131 euros. Rough rice for May delivery gained 1.1 percent to $13.12 per 100 pounds in Chicago. Production in Thailand and Vietnam, the two largest exporters, may be hurt by drier-than-normal weather that’s parched farms and cut water levels in the Mekong River, according to the United Nations’ Food and Agriculture Organization. The Thai harvest that begins this month, which accounts for about 25 percent of annual output, may drop to 7 million tons from 8.4 million last year, said Concepcion Calpe, a senior economist at the UN agency. Output from Vietnam’s end-of-year harvest “may be affected,” Calpe said in a phone interview from Rome yesterday. --With assistance from Luzi Ann Javier in Singapore.
