Cotton futures fell the most in 10 weeks, and crude oil dropped to the lowest since mid-July. Gasoline declined for the ninth straight session, the longest slump since at least October 2005. Copper dropped to the lowest since Sept. 7.
The International Monetary Fund cut its 2012 global-growth forecast to 3.3 percent on Oct. 9 from a July prediction of 3.5 percent and said the euro area will contract 0.4 percent. The economy in China, the biggest user of everything from copper to cotton, has slowed for seven straight quarters.
