Metals prices closed higher Friday on hopes that political stability will return to Italy and Greece.
Copper for December delivery jumped 8.95 cents, or nearly 3 percent, to close at $3.4635 per pound. December palladium gained $15, or 2 percent, to close at $662.80 an ounce.
January platinum rose $19.40, or 1 percent, to $1,646.70 an ounce.
Traders were encouraged by news that Italy and Greece were moving closer to forming new governments that can get their respective debt problems under control. If the European financial crisis is contained, it could boost economic growth and demand for raw materials like copper and palladium. The metals are used in everything from housing to television sets.
Crop prices didn't do as well. The USDA predicted earlier this week that corn supplies next year won't fall as sharply as traders had expected. The news sent corn, wheat and bean prices lower. Wheat and corn prices continued to fall Friday, while soybeans rose higher. All those crops ended the week lower.
Corn for December delivery dropped 7 cents Tuesday, or nearly 2 percent, to settle at $6.385 per bushel. December soybeans gained 8 cents to $11.755 a bushel. December wheat lost 3.25 cents to finish at $6.1675 per bushel.
