Gold and other metals slid further Wednesday as the dollar rose for a second straight day.
Gold for February delivery lost $5.60 to settle at $1,092.50 an ounce on the New York Mercantile Exchange.
Following a months-long trend of trading inversely with the dollar, gold fell as the ICE Futures U.S. dollar index gained 0.1 percent. The index is a widely used measure of the dollar's performance against other currencies.
Gold is used as a hedge against inflation and a weaker dollar, so demand for the metal tends to diminish when the greenback is stronger.
The price of gold has fallen about 10 percent from a record high of $1,227.50 on Dec. 3 as the dollar has steadied, but is still up 24 percent for the year.
The dollar is likely to dictate which way gold goes next year as well. Many analysts expect the Federal Reserve to raise interest rates before 2010 is over, which would boost the dollar and potentially hurt gold prices.
But a rate hike might also be a boon to gold, depending on how traders look at it. Higher interest rates are used to ward off inflation. If the Fed signals that inflation is becoming a threat by raising rates, gold prices may spike as investors look for ways to safeguard their money.
