According to gold dealers the bullion price in Karachi recorded a rise of Rs 136 per ten grams to Rs 42,107 per ten grams. In per tola term, gold price increased by Rs 159 per tola to close at Rs 49,061 per tola. Similarly gold prices in Lahore stood Rs 42,015 per ten grams, in Hyderabad it remained at Rs 42,000 per ten grams and in Multan it stood around Rs 42,000 per ten grams, they added. Humayun Ahmad Mani, a dealer attributed the hike in gold prices to the improved investment and demand by strong investors and short supply fears on Fed Reserves rate likely to rise. He said the fund managers pumped more money into commodities ahead of the second quarter-end in international market. Mani said, on average gold prices kept goldsmiths and jewellery sector from hefty buying during last six months. However the gold hedgers made some cautious deals. The general buyers remained on sidelines anticipating easing in price in coming days on dollar-rupee parity. Buyers made deals according to their immediate needs. Local trading in gold remained dull on back of insignificant buying. Local dealers said the domestic gold prices are rising in line with the trend of global gold markets. But, the increase is usually not as much as takes place internationally because people stop buying the metal when prices are too high.
