Gold inched lower on Thursday but prices were set for their biggest quarterly gain since September 2020, as the Russia-Ukraine conflict lifted demand for the safe-haven metal.
* Spot gold was down 0.3% at $1,926.46 per ounce by 0245 GMT. U.S. gold futures were down 0.4% at $1,931.00.
* The metal has gained about 5.6% so far in the quarter and 1% in the month.
* Ukrainian forces are preparing for new Russian attacks in the east of the country as Moscow builds up its troops there after suffering setbacks near the capital Kyiv, President Volodymyr Zelenskiy said on Thursday.
* The dollar index slipped to a near one-month low in the previous session, making gold less expensive for other currency holders.
* U.S. Treasury yields fell while a key part of the yield curve steepened on Wednesday, unwinding recent moves betting that aggressive Federal Reserve policy tightening could send the world's largest economy into recession.
* Lower yields reduce the opportunity cost of holding non-paying bullion.
* Spot silver fell 0.7% to $24.67 per ounce, but was on course for its best quarterly rise since June 2021. Platinum shed 0.6% to $984.26 but was set for its biggest quarterly gain since March 2021.
