Gold advances on softer US dollar, bond yields ahead of payrolls report

Meanwhile, oil prices edged lower, with top aides of U.S. President Donald Trump pushing to keep the Iran war from escalating before November's midterm elections.

Among other metals, spot silver XAG= gained 0.5% to $65.61, platinum XPT= rose 0.2% to $1,763.88, and palladium XPD= climbed 1.4% to $1,363.56.

Gold extended gains on Thursday, buoyed by a drop in the U.S. dollar and Treasury yields from highs, as investors awaited key payrolls data that could tip the scales on expectations for a Federal Reserve rate hike this month.

Spot gold XAU= was up 0.9% at $4,425.83 per ounce by 1046 GMT, while U.S. gold futures GCcv1 rose 1.3% to $4,472.

Bullion slipped to its lowest level since August 7 on Wednesday before settling more than 1% higher as the U.S. dollar index retreated from nearly three-week peak, while Treasury yields eased from multi-year highs.

"Modestly weaker dollar, and slightly lower U.S. rates are helping gold. With the Fed currently offering no forward guidance, gold remains highly sensitive to shifts in market expectations for the September meeting," said UBS analyst Giovanni Staunovo.

Traders are pricing in about a 60% chance of an interest rate hike at the Fed's policy meeting later this month, according to the CME FedWatch Tool.

Rate hike bets increased after Fed Chair Kevin Warsh last week signalled that the central bank may need to hike rates if above-target inflation persists.

Although gold is typically seen as an inflation hedge, higher interest rates tend to diminish non-yielding bullion's appeal.

Investors now await the closely watched non-farm payrolls report due on Friday after the ADP employment report on Wednesday showed that U.S. private payrolls increased moderately in August.
