Gold prices edged down on Wednesday, on track for their biggest monthly decline since November 2016, as upcoming US jobs data and taper talks from the US Federal Reserve kept investors on the sidelines.

Spot gold eased 0.2% to $1,758.50 per ounce by 1208 GMT, having touched its lowest since April 15 at $1,749.20 on Tuesday. US gold futures fell 0.2% to $1,759.40.

Bullion prices are down about 8% for the month, weighed down by the Fed's sudden hawkish shift. But they are up 3% for the quarter.

Equity markets remain strong as the economy recovers, and "that's something which potentially will be a drag on gold", as it is considered as safe haven asset, UBS analyst Giovanni Staunovo said, adding, bullion could drop towards $1,600 by the end of the year.

Investors are also eyeing the non-farm payrolls on Friday, which if comes out strong, could further pressurise gold, Staunovo added.

The US Labor Department expected to report a gain of 690,000 jobs in June, compared with 559,000 in May, according to a Reuters poll of economists.

Meanwhile a "very optimistic" Federal Reserve Governor Christopher Waller on Tuesday said the US central bank may need to start dialling down its massive asset purchase programme as soon as this year to allow the option of raising interest rates by late next year.

Elsewhere, silver rose 0.5% to $25.86.

"While outperformance is likely, we see limited prospect of a rising silver price in a falling gold market," Morgan Stanley said in a note, adding, it was holding its forecast for silver at a flat $25 to mid-year 2022.

Palladium lost 0.6% to $2,694.29 per ounce, and was set for a second straight month of declines.

Platinum fell 0.7% to $1,059.46 and was set for its biggest monthly and quarterly drop since March 2020.
