Commodities prices are mostly higher as traders keep a close eye on the talks in Washington aimed at avoiding a U.S. government default.
Gold and silver inched up. Many traders expect precious metals prices to jump if a deal isn't reached and investors park their money in safe-haven assets.
December gold rose $8.40 to $1,276.60 an ounce Monday. Silver for December delivery rose 9.5 cents to $21.354 an ounce.
Energy prices were mixed. Oil has been fluctuating as hopes build and then diminish for a deal to extend the U.S. government's borrowing authority and to end a partial shutdown of the federal government.
Crude for November delivery rose 39 cents to close at $102.41 a barrel in New York.
Corn, soybeans and wheat futures closed slightly higher.
