SINGAPORE – Gold headed for the biggest weekly loss in three years as progress in US-China trade talks hammered demand for havens and sent miners’ shares tumbling.

The metal dropped 3.7% this week, the most since November 2016, as China and the US indicated they are heading toward an interim deal to halt the trade war. Some signs of stabilization in the global economy have also dented gold’s allure, and JPMorgan Chase & Co and Citigroup closed out their bets on the traditional haven.

Other precious metals also plunged, with silver losing 7.6% of its value this week.

Gold prices got a lift this year from trade frictions, interest rate cuts from the Federal Reserve, and robust demand from investors and central banks.

That trio of drivers is now under attack as the two largest economies near an initial pact, with the sides agreeing to a tariff rollback as part of any deal. At the same time, the US central bank recently indicated that, after three rate cuts, policy makers are now pausing.

“The dollar appears to be in an uptrend pattern after a month of sideways action and fresh weakness on the charts early today suggests the bear case in gold is still unfolding,” according to the Hightower Report.

Gold remained under pressure on Friday even as stocks took a breather after Thursday’s gains.

The large long positions in gold left the metal vulnerable to sharp drops, said Georgette Boele, an ABN Amro Bank NV strategist.

“If only a small amount of positions is closed, gold prices are back at $1 400,” she said. A profit-taking wave could turn into a “bearish vibe,” causing investors to doubt the positive outlook in gold prices, she said.

Spot gold was down 0.8% on Friday at $1 457.31 an ounce, after tumbling 1.5% on Thursday. Australia’s Newcrest Mining hit a five-month low and AngloGold Ashanti dropped to the lowest since October 1.

“The principal driver behind the weakness in gold has been increasing optimism about the trade outlook,” John Sharma, an economist at National Australia Bank, said in an email. “However, it should be remembered that the trade deal is not done and dusted.”
