Spot gold rose to a 1-1/2-week high on Wednesday, supported by a weaker dollar and renewed worries about the eurozone's debt problem after Moody's slashed Portugal's credit rating to junk. Spot gold rose to $1,518.44, its highest since June 24, before easing to $1,516.94 by 0626 GMT, up $1.24 from the previous close. US gold edged up 0.3 percent to $1,517.50. Spot silver led the precious metals complex with a 1 percent gain. It rose earlier to $35.92, highest since June 23.
Spot platinum hit $1,739.50, its highest in nearly two weeks, in an attempt to cross above the 20-day moving average at $1,740.70. It was last quoted at $1,736.50.
