otton futures rose the most in a week amid declining output in the U.S., the world’s biggest exporter. Orange juice and cocoa advanced, while coffee fell.

Cotton production may fall 19 percent this year, the U.S. Department of Agriculture said on May 10. World stockpiles will rise 9.4 percent to a record in the year starting Aug. 1 with most of the gain in China, the biggest user. The "overhang" probably won’t affect world prices if China maintains reserves, said John Flanagan, the president of Flanagan Trading in Fuquay- Varina, North Carolina.

"I don’t really see any reason for the market to sell off," Flanagan said in a telephone interview. "As long as China is willing to hold their prices high, there’s no reason for us to have lower prices."
