NEW YORK, Nov 2 (Reuters) - Gold rose on Tuesday as a sharp dollar drop prompted bullion buying a day before the Federal Reserve was expected to announce another round of U.S. government bond purchases to boost the economy.
Strong physical bullion demand from leading consumers India and Turkey ahead of major gold-buying events also buoyed prices, analysts said.
The U.S. Federal Reserve opened a two-day meeting on Tuesday that is expected to conclude with a decision to pump hundreds of billions of dollars into the tepid economy.
"As long as the monetary authorities are expanding their balance sheets, the propensity for gold to move higher is... rising," said Dennis Gartman, hedge fund manager and publisher of the Gartman Letter.
Analysts expectations range from $250 billion to $2 trillion of bond purchases by the Fed in a second round of quantitative easing (QE2). Traders are bracing for a quick rise in the dollar -- and commensurate fall in commodities -- if the Fed takes a less aggressive approach.
Policymakers are hoping purchases of U.S. government bonds will further reduce borrowing costs and spur more spending, which would be bullish for assets such as gold. [
