Copper Advances to One-Week High as BoJ Signals Stimulus

Copper reached a one-week high in New York after the Bank of Japan said it will shift to open-ended asset purchases to help spur economic growth.

Central bank officials voted to adopt a 2 percent inflation target and will begin the asset purchases next year. Japan is the world’s fourth-biggest user of the metal. Copper prices climbed 6.3 percent last year as central banks in the U.S., Europe and China increased efforts to boost economies.
