``Declining oil prices dragged gold prices lower,'' said Kazuhiko Saito, chief analyst at Interes Capital Management in Tokyo. ``Investors are cautious about taking new positions as they want to watch whether gold prices can hold above $640.''
Gold for immediate delivery fell as much as $1.70, or 0.3 percent, to $644.40 an ounce, and traded $645.20 at 11:10 a.m. in Singapore. The precious metal rose to $654.65 yesterday, before closing down $2.70, or 0.4 percent, at $646.10.
Gold prices often reflect investors' expectations for inflation as the commodity can preserve its value better than other assets when the rate of price gains accelerates. Gold futures reached a record $873 an ounce in January 1980 after oil costs doubled in a year, sparking a surge in inflation.
