Spot gold edged down 0.1% to US$5,181.18 per ounce by 8.37am.

The metal has climbed 6.5% so far in February, bringing gains for the seven months to a whopping 58%.

US gold futures for April delivery were up 0.1% at US$5,198.10.

“There are two things (supporting gold). First is the tariff uncertainty which is there in the market right now, and on the other hand, the Iran and the US situation,” said ANZ analyst Soni Kumari.

The US and Iran held indirect talks in Geneva on Thursday over their long-running nuclear dispute, with the Omani mediator saying the two sides had made progress.

They plan to resume negotiations with technical-level discussions scheduled next week in Vienna.

“The latest rounds of talks have not produced a clear outcome, leaving geopolitical risks present but not escalating.

“This has kept gold at elevated levels, though it has not yet provided sufficient momentum to establish a sustainable bullish trend,” said Linh Tran, senior market analyst at XS.com.

The US began collecting a temporary new 10% global import tariff on Tuesday.

However, the rate will rise to 15% for some countries, US trade representative Jamieson Greer has said.
