Soybeans and corn rose in Chicago as gains by crude-oil futures boosted the appeal of crops processed to make biofuels.

November-delivery soybeans climbed 0.6 percent to $9.0525 a bushel on the Chicago Board of Trade at 12:45 p.m. Paris time, paring an increase of as much as 0.9 percent. Corn for December delivery added 0.4 percent to $3.8075 a bushel.

“A lot of the strength came from positive developments in outside markets,” Toby Hassall, an analyst at CWA Global Markets Pty, said by phone from Sydney today. Advances by crude today and U.S. and European equities yesterday helped boost investor sentiment in grain markets, he said.

Crude for August delivery rose as much as 0.6 percent to $72.38 a barrel on the New York Mercantile Exchange on speculation supplies in the U.S. fell last week, boosting fuel- demand optimism. The Standard & Poor’s 500 Index yesterday climbed 0.5 percent, rising from a 10-month low.

Still, expectations of larger soybean and corn supplies may curb grain and oilseed futures in Chicago, Hassall said.

The U.S. Department of Agriculture may raise its estimate for the nation’s soybean stockpiles to 369 million bushels at the end of the 2010-11 season from last month’s forecast of 360 million, Allendale Inc., a farm marketing adviser and broker, said in a report e-mailed today.

Corn Stockpiles

The U.S. corn-inventory estimate may rise to 1.582 billion bushels at the end of the 2010-11 season from 1.573 billion last month, Allendale said. The USDA is scheduled to release its latest forecasts on global agricultural supply and demand on July 9 in Washington.

China, the second-largest corn consumer, may boost imports 10-fold to 10 million metric tons by 2015 as economic growth fuels demand, said Akio Shibata, chief representative for the research unit of Marubeni Corp., Japan’s biggest grain trader.

Wheat for September delivery slipped 0.1 percent to $5.07 a bushel. Milling wheat for November delivery traded on NYSE Liffe in Paris added 0.5 percent to 158 euros ($198.89) a metric ton, climbing for a seventh day in a row.
