Gold prices have fallen in London markets for the second day in a row. This follows speculation that US data will strengthen the dollar and boost the case for the Federal Reserve to slow stimulus. The yellow metal fell by 0.6 per cent to 1,224 dollars an ounce and silver by 1.8 per cent to 19.52 dollars an ounce. The US Federal Open Market Committee decided at the December 17-18 meeting to cut monthly bond purchases to 75 billion dollar from 85 billion dollar starting this month. San Francisco Fed President John Williams said that the programmemay end this year.
