May 28 (Bloomberg) -- Cotton futures fell, capping the longest slump in 11 months, on signs of ample global supplies.

World stockpiles of cotton on July 31, 2014, will rise 9.4 percent to a record 92.74 million bales from a year earlier, the U.S. Department of Agriculture said on May 10. A bale weighs 480 pounds, or 218 kilograms. The dollar rallied as much as 0.6 percent today against a basket of six major currencies, eroding the appeal of exports from the U.S., the worldΆs top shipper.

“In the grand scheme, thereΆs plenty of cotton to go around,” Keith Brown, the president of Keith Brown & Co., a broker in Moultrie, Georgia, said in a telephone interview. “The dollar continues to stay up, which is another negative for cotton.”

Cotton for July delivery slipped 0.1 percent to close at 81.42 cents a pound at 2:30 p.m. on ICE Futures U.S. in New York. The price fell for the sixth straight session, the longest slide since June 5.
