Gold prices rose on Friday but was on track for a weekly loss, as rising US Treasury yields and growing expectations of Federal Reserve rate hikes weighed on the metal.

Spot silver gained 1.4% to $64.82 per ounce, platinum added 1.7% to $1,777.38 and palladium fell 0.4% to $1,269.77. All three metals were poised for weekly losses.
