Gold prices are rising again on Friday and may end this week in positive territory after a five-week series of declines, MarketWatch writes.

Silver for September delivery shed 0.1% to $18.70 an ounce.

Gold has been supported this week by declining US Treasury yields, said Craig Erlam, senior market analyst at OANDA. On Friday, the yield on 10-year US Treasuries is in the region of 2.82%, having fallen more than 20 basis points since the start of trading on Thursday.
