NEW YORK/LONDON, Nov 4 (Reuters) - Copper surged to its highest in more than two years on Thursday as the dollar faltered and risk appetite grew a day after the U.S. Federal Reserve detailed plans to boost growth in the world's largest economy.
The Fed on Wednesday said it would buy about $600 billion in longer-term Treasury bonds through the end of June 2011, in an effort to lower borrowing costs for consumers and businesses still suffering from the worst recession since the Great Depression. [ID:nN03163902]
Investors cheered the package, driving prices of riskier assets such as stocks and industrial metals higher, while dumping their safe-haven bets in the dollar.
"The one thing that we took away from yesterday's Fed package was it's not going to change the dollar's direction," said Justin Lennon, analyst at Mitsui Bussan Commodities (U.S.A.) Inc.
On the London Metal Exchange (LME), benchmark copper for three-month delivery CMCU3 ended up $280 at a session high of $8,600 a tonne. It was copper's biggest percentage gain in 3-1/2 months and a price not seen since July 2008, when it touched an all-time record at $8,940 a tonne.
On the COMEX metals division of the New York Mercantile Exchange, copper for December delivery HGZ0 shot up 12.70 cents, or 3.4 percent, to settle at $3.9120 per lb, the highest level on a settlement basis for the second-position futures contract since July 3, 2008.
"I think the dollar weakness is not over for this quarter. In the coming two months we might see further gains (in metals)," said Peter Fertig, analyst at Quantitative Commodity Research.
A weaker dollar tends to make commodities priced in the U.S. currency cheaper for holders of other currencies. The dollar's losses accelerated after the European Central Bank decided to hold interest rates steady. [USD/]
Also helping copper's ascent, Chile's Collahuasi mine union said on Thursday workers would start striking at the world's No. 3 copper mine early on Friday. [ID:nN04101727]
"In this environment, any commodity that picks up a bullish fundamental will tend to outperform," said Sterling Smith, an analyst for Country Hedging Inc in St. Paul, Minnesota.
"It's kind of hard today to separate how much of this was the mine strike and how much was the quantitative easing pushing copper up, but again, this development could easily boost prices coming into the end of the week," he said.
Still, the market needs to get through Friday's key U.S. monthly employment report, which will give investors a better idea of prospects for the U.S. economic recovery, and, by implication, for metals demand.
Industrial metal markets have in recent weeks started to fret that Chinese plans to restrict energy consumption to cut emissions would hamper the country's production capability.
"That is the overriding issue. I haven't heard that it is impacting copper smelters yet, but I think it will," said Fairfax analyst John Meyer said.
Analysts estimate that energy accounts for about 25 percent of production costs of industrial metals. [ID:nTOE69H066]
The number for aluminum is about 40 percent globally, while in China, energy accounts for nearly 50 percent of total aluminum production costs.
Three-month aluminum CMAL3 ended up $43 at $2,460 a tonne, after earlier touching its highest since April, at $2,492.
Zinc CMZN3 jumped nearly 5 percent to $2,520 a tonne, reversing most of the previous session's loss on plans by China's State Reserves Bureau to sell 50,000 tonnes of zinc ingots. [ID:nBJI002437] [ID:nLDE6A31HD]
It jumped $107 to end at $2,512.
Lead CMPB3 rose $94 to finish at $2,529 a tonne and tin CMSN3 firmed $650 to $26,500.
Nickel CMNI3 peaked at $24,605 a tonne, its highest since Oct. 14, before ending up $950 at $24,500. Metal Prices at 1909 GMT COMEX copper in cents/lb, LME prices in $/T and SHFE prices in yuan/T Metal Last Change Pct Move End 2009 Ytd Pct
