Commodities Update — Gold edges higher; Wheat drops to 11-week low; Copper edges up ahead of recession fear 

RIYADH: Gold prices edged up on Tuesday as the dollar eased, while investors kept a keen eye on posturing from major central banks on interest rate hikes for a clearer outlook for bullion.

A weaker dollar makes greenback-priced bullion more attractive for buyers holding other currencies.

Spot gold was up 0.2 percent at $1,841.13 per ounce by 0200 GMT, after largely range-bound trading on Monday. US gold futures firmed 0.1 percent to $1,842.90.
