Copper hit its highest price in almost two months on Monday as investors took heart from rising factory output growth in top consumer China, although data also showed Chinese exports and imports were below forecasts, tempering the metal's gains. Also restraining the rise in copper was news of Italian Prime Minister Mario Monti's surprise decision to resign early, raising political risk in a country that remains a focus of the euro zone debt crisis.
Three-month copper on the London Metal Exchange closed up 1.3 percent at $8,140 a tonne, extending a small gain from the previous session, when it logged a fourth week of gains. Prices earlier hit $8,159 a tonne, the highest since October 19. China's copper imports rose 13.5 percent in November from the previous month but the figure was boosted by the arrival of delayed shipments after a week-long holiday, meaning overall demand remained weak.
"The Chinese macro data was relatively good with a slight uptick in terms of industrial production, investment etc and although the copper numbers were not particularly good themselves I think the sentiment is starting to turn a little bit," Standard Chartered analyst Daniel Smith said.
Supporting the industrial metals outlook, South Korea, the world's fourth biggest base metals buyer, will raise purchases by its state-run procurement agency (PPS) by 20 percent in 2013, an agency official said on Monday. The PPS also said it would list a 1,100-tonne copper commodity exchange traded fund (ETF) worth $10 million on South Korea's stock exchange on December 17.
Back in China meanwhile, Barclays Capital said it expects copper demand to remain soft and that the country will export more metal next year, perhaps averaging 10,000 to 15,000 tonnes per month. "This week has seen further incremental Chinese data improve, but concerns remain over the potential for a copper surplus in 2013 and the ability of miners to balance growth and shareholder return in the current environment," Macquarie analysts said in a note.
