Spot gold was up 0.1 per cent at $1,770.66 per ounce by 0119 GMT, U.S. gold futures rose 0.2 per cent to $1,770.30 per ounce. Palladium rose 0.3 per cent to $2,944.19 per ounce, after scaling all time high of $3,007.73 per ounce on Friday. The dollar index was down 0.1 per cent against its rivals, making gold less expensive for other currency holders. U.S. Treasury Secretary Janet Yellen on Sunday tamped down concerns that President Joe Biden's plans for infrastructure, jobs and families will cause inflation, saying the spending will be phased in over a decade.
