Gold prices fell by another Rs 100 to Rs 30,600 per 10 grams at the bullion market today, largely in tandem with a weak global trend amid muted demand from local jewellers. Silver also cracked below the Rs 41,000-mark by falling Rs 700 to Rs 40,500 per kg on reduced offtake by industrial units and coin makers. Traders said a weak trend overseas, as market’s focus turned to a two-day US Federal Reserve meeting that kicks off later in the day, kept pressure on the precious metal here. Besides, the dollar’s strength against a basket of major currencies overseas weighed on gold prices, they added. Globally, gold fell per cent to $1, an ounce and silver by per cent to $ an ounce in Singapore. In addition, fading demand from local jewellers and retailers at domestic spot market also dampened sentiments.
