Copper advanced for the first time in seven days in London as industrial metals gained after the yuan strengthened against the dollar to the highest since 1993. Three-month delivery copper soared as much as 3.4 percent to $8,884.75 a metric ton on the London Metal Exchange and traded at $8,840 at 11:52 a.m. Shanghai time. Zinc advanced as much as 4.3 percent to $2,190 a ton and traded at $2,180 while nickel gained 3.5 percent to $21,700 a ton. Metals increased as the currency of China, the biggest consumer of metals, rose beyond 6.4 per dollar, supported by the Federal Reserve’s pledge to keep interest rates at a record low and signs China will use currency gains to help rein in inflation. Copper imports by China climbed to the highest level since January last month as traders bought the metal ahead of an expected seasonal rise in demand. “We see Chinese buying supporting London prices during Asian hours from time to time recently,” Xu Liping, an analyst at HNA Topwin Futures Co., said by phone from Shanghai. “In today’s case, a strong opening in Shanghai boosted London prices. A price below $9,000 is attractive to buyers here.” The yuan strengthened the most since November and 12-month non-deliverable forwards climbed to a three-month high after the central bank’s daily fixing had its biggest jump of 2011. China’s consumer prices climbed 6.5 percent last month from a year earlier, the fastest in three years, official data show. ‘Good for Commodities’ The strength of the currency “is definitely good for commodities as that allows China to import more, and it’s a sign that the government is confident enough about the strength of domestic demand and cares less about exports,” said David Thurtell, head of metals research at Citigroup Inc. in Singapore. Imports of the refined metal, copper alloy and semi- finished products, gained for a second month, rising 9.5 percent to 306,626 tons from 280,009 tons in June, the General Administration of Customs said on its website yesterday. Demand for the metal used in cables and wires is usually subdued in the summer, when power supply disruptions can curb production. Fabricators usually ramp up production from September as electricity supplies improve. China may adopt “targeted easing” in the second half to support financing for agriculture, small and medium-sized enterprises and social housing, the China Securities Journal reported today, without saying where it got the information. Potential Stimulus “Market expects some sort of stimulus policies from China if the condition worsens,” Xu said. Premier Wen Jiabao chaired a State Council meeting on Aug. 9 and urged global cooperation to stabilize financial markets after a U.S. credit rating downgrade by Standard & Poor’s and Europe’s debt crisis triggered a slump worldwide. Minera Escondida Ltda., the operator of the world’s largest copper mine in Chile, said a 15-day workers strike “had no relevant impact” on output, it said in a filing to the regulator’s website. Copper for October delivery on the Shanghai Futures Exchange dropped 0.6 percent to 66,660 yuan a ton. Aluminum in London gained 0.9 percent to $2,418 a ton and lead advanced 2.4 percent to $2,330 a ton. Tin climbed 4 percent to $23,650. --Helen Sun.
