Gold gained for the second time in three days as weaker U.S. economic growth and Russia-Ukraine tension underpin demand for haven assets. Palladium advanced to the highest since April amid supply concerns.
Gold extended its 2014 rally, climbing to a three-month high as speculation that U.S. stimulus will continue boosted the appeal of alternative assets. Silver rose in the longest run of gains since 2011.
Gold and silver futures fell the most in two months as the U.S. faced opposition from Russia on a military strike against Syria, eroding demand for a haven. Platinum and palladium posted the biggest declines in 10 weeks.
