Gold prices on Wednesday slipped by Rs180 to trade at Rs26,870 per 10 grams at the bullion market in the national capital on low demand from jewellers amid a weak global trend. Silver, too, declined by Rs 60 at Rs 36,800 per kg. Bullion traders attributed the fall in prices of the yellow metal to a weak global trend, where gold ruled below $1,200 an ounce, and subdued demand from jewellers and retailers. Gold in Singapore, which normally sets price trend on the domestic front, traded a shade lower at $ 1,191.47 an ounce from $ 1,192.78.
