Sept. 18 (Bloomberg) -- Copper may rise in London as a weaker dollar spurs concern about inflation and makes raw materials priced in the currency cheaper for holders of other monies, a survey showed. The Dollar Index, a six-currency gauge of the greenback’s performance, has dropped 6.3 percent this year. The U.S. currency fell yesterday within a penny of the lowest in a year against the euro. Eight of 16 analysts, investors and traders surveyed by Bloomberg, or 50 percent, said the metal would rise next week. That was the first forecast for higher prices since the week ended May 29. Five expected a drop, and three predicted little change in prices. Copper for three-month delivery was up 2.1 percent this week at $6,379.50 a metric ton at 5 p.m. yesterday on the London Metal Exchange. The weekly copper survey has forecast prices accurately in 27 of the past 55 weeks, or 49 percent of the time. This week’s survey results: Bullish: 8 Bearish: 5 Hold: 3 To contact the reporter on this story: Anna Stablum in London at astablum@bloomberg.net
