NEW YORK ( TheStreet) -- Gold futures and shares of gold-mining companies took a sharp turn higher Wednesday after the Federal Reserve surprised the market by announcing a continuation of bond purchases, currently at $85 billion a month.The Market Vectors Gold Miners ETF ( GDX), which tracks shares of gold miners, climbed almost 9%, while the widely followed SPDR Gold ETF ( GLD), which is backed by physical gold, gained more than 4.3%, its largest one-day increase since 2012. Gold's rally may be too little too late for gold miners Newmont Mining ( NEM), Anglogold Ashanti ( AU), Barrick Gold ( ABX) and Goldcorp ( GG), which are stuck in a downward trend. Wednesday's spot gold prices provided miners a reprieve to catch their collective breaths after GDX, the ETF that tracks their stocks, neared the lows of 2008. The Fed announcement, however, is unlikely to boost the price of the yellow metal high enough to give the miners a sufficient spread between production costs and the price at which they can sell gold on the open market. One significant headwind facing gold bulls and miners is a one-two punch from India, one of the world's largest consumers of gold. First, India's currency, the rupee, is trading near its weakest levels against the dollar in more than 10 years. Thursday morning it took 61.93 rupees to buy a greenback. To put that into context, when gold hit its 2011 highs, it took only about 45 rupees to purchase a buck. This means that for Indian consumers, gold is still trading near all-time highs. The second punch comes from the Indian government, with a 50% tax increase for gold jewelry imports this week, as reported by Reuters. India in part raised the tax as a domestic protection measure, but it also wants to diminish the crippling balance of trade that has sent the rupee crashing. Imported jewelry is a relatively small percentage of the overall bullion India imports, but the tax increase is part of an overall government pattern of trying to decrease gold imports. Unlike investors in spot gold, investors in gold-mining stocks are not yet ready to enjoy Wednesday's spike.
