Spot gold was down 0.3 per cent at $ 1,260.72 an ounce, as of 0800 GMT, after touching its weakest since Dec. 18, 2017 at $ 1,257.74 earlier in the session.
US gold futures for August delivery were 0.5 per cent lower at $ 1,262.40 per ounce.
“Rising trade tensions should have (but did not) help gold’s cause all that much. Instead, it seems that the concern of rising interest rates, particularly in the US, continues to gnaw away at gold, as does the fact that the fund length is fleeing,” INTL FCStone analyst Edward Meir said in a note.
US Fed Chairman Jerome Powell last week said the central bank should continue with a gradual pace of interest rate rises amid a strong economy to balance its employment and inflation goals.
Gold, which is highly sensitive to rising US interest rates, could see demand take a hit from higher rates, as these tend to boost the dollar and push bond yields up.
“Trade tensions aren’t helping gold at all, there is only one clear trend which is skewed to the downside. By looking at the chart, it appears that bulls have left the town,” said ThinkMarkets chief market analyst Naeem Aslam.

Gold, usually seen as a safe store of value during economic and political uncertainty, has found only limited support from the ongoing global trade spat.
“The market certainly looks susceptible to some further declines until data shows any sort of weakness in the US economy in particular,” said ANZ analyst Daniel Hynes.
