The two-day summit is set to adjourn on Friday yet leaders of the 27 European Union member nations failed to secure changes to the body's treaty. The 17 countries that exchange the euro and additional interested nations could move forward. Though gold futures were poised to climb on Friday, bullion this week is set for losses of about 1.5 percent.
"(Gold's) latest relative weakness can be expected to prompt investors – who recently took a positive view of gold – to continue shedding their positions," states a note penned by Commerzbank analysts, cited by Reuters. "A possible price slide below $1,700 may thus accelerate a further slump. Despite these short-term tendencies, we do not believe gold's long-term upwards trend to be under threat."
At 9:15 a.m. on Friday, gold futures fell 0.9 percent, a $1.60 loss to $1,711.80 per troy ounce.
EU leaders also have to figure out how to reconcile divisions in strategies to tackle the sovereign debt scourge, according to The Wall Street Journal.
