Metals prices slid Friday on renewed fears that the European debt crisis could slow global economic growth.

Italy became the latest country to see its costs for borrowing money skyrocket, entering the territory of nations that have required massive bailouts from the European Union. Italy must pay an average yield of 7.814 percent in two-year bonds, nearly double what the country had to pay only a month ago.

The revelation comes on the heels of a disastrous bond offering from Germany, which saw little demand for investment in the continent's strongest economy. The inability to raise cash inexpensively could drastically hurt sales of industrial metals that are closely tied to economic growth. Metals like copper and palladium are used as raw materials to make everything from automobiles to home computers.
