PRICE MOVES: Commodities rose broadly on hints that there could be progress in U.S. budget negotiations and Greece's debt problems.

Some economists believe the U.S. could fall into a recession without an agreement. Separately, the Greek government presented legislation aimed at winning its next bailout payment.
DOLLAR'S IMPACT: Commodities benefited from a weaker dollar. Since commodities are priced in dollars, a weaker dollar makes them cheaper for traders who use other currencies.
