Shanghai copper firms up

Shanghai copper rose 1.8 percent yesterday, and London futures extended the previous session's rally buoyed by a weak dollar and rising equity markets after more positive US manufacturing data.

US industrial production rose for a second consecutive month in August and consumer prices also rose more than expected but inflation risks in the economy remain low, sending the dollar to one-year lows against the euro and a basket of currencies.

"Our economists expect further recovery in industrial production in the United States for the rest of the year," Barclays Capital Yingxi Yu said.
