NEW YORK: Gold pushed above $1,400 an ounce Tuesday as improving retail sales sparked interest in the precious metal as a hedge against inflation. Gold for February delivery rose $6.30 to settle at $1,404.30 an ounce. Silver, platinum and palladium all settled higher amid expectations for improving demand. In contracts for March delivery, silver rose 16.4 cents to settle at $29.788 an ounce, palladium added $15.75 to $768.20 an ounce and copper gained 0.2 cent to $4.2015 a pound.

New York's main contract, light sweet crude for January, declined 33 cents to $88.28. Brent North Sea crude for delivery in January was stable, rising only two cents to $91.21 a barrel in London trade.
