Metals prices surged Wednesday on news that the world's central banks will launch a coordinated effort to lower borrowing costs and shore up the global financial system.
The central banks of Europe, the U.S., Britain, Canada, Japan and Switzerland made a surprise announcement of the extraordinary effort Wednesday. It eased worries that the financial crisis in Europe might drag down economic growth.
Metals prices slumped this fall as the European financial crisis intensified.
Traders think the central banks' effort will boost global growth, which could increase demand for raw materials like palladium and copper. The metals are used to make consumer goods and industrial products.
