Gold ends roller-coaster day down B50

Gold prices in Bangkok were on a roller-coaster ride on Monday, ending down 50 baht from the previous trading day on Saturday.

The Gold Traders Association announced the buying price at 20,650 baht and the selling price at 20,550 baht per baht-weight for bullion.

For ornaments, the buying and selling prices were 20,177.96 baht and 21,150 baht per baht-weight respectively.

The prices changed 12 times as of 5.09pm on Monday, indicating high volatility, for a net loss of 50 baht from the previous trading day on Saturday.

Reuters reported from Bengaluru, India, that gold fell 1% on Monday to hit its lowest in over five months, pressured by a stronger US dollar and expectations the Federal Reserve will raise interest rates in December.

Spot gold was down 0.6% at $1,218.90 an ounce by 0245 GMT. The metal fell as much as 1% to $1,213.15 an ounce earlier in the session -- its lowest since June 3.

US gold futures slipped 0.5% to $1,218.50 per ounce. A broad sell-off in global commodities and surging bond yields on speculation a splurge of US infrastructure spending could stoke inflation, sent the metal dipping nearly 3% on Friday.

US Treasury futures declined to 10-month lows on Friday as bond investors worried that US President-elect Donald Trump would enact policies that increase inflation, which reduces the value of debt.

"What we're seeing today is the continuation of long liquidation going through the market," said Jeffrey Halley, senior market analyst at OANDA.

"People seem to have unwound their Trump-risk and are now talking more about 'Trumpfation', with Trump's fiscal policies that he wants to enact with all this infrastructure that would push up inflation and that would push up borrowing rates and yields in the States," Mr Halley said. "When yields go up in the US, the appeal of other assets, such as gold ... becomes less."

Meanwhile, the dollar rose to a nine-month high against a basket of major peers early on Monday.

Fed vice chair Stanley Fischer said on Friday that US economic growth prospects appear strong enough for the Fed to proceed with a gradual increase in interest rates. Gold is highly sensitive to rising rates, which lift the opportunity cost of holding non-yielding assets such as bullion, while boosting the dollar, in which it is priced.

"I think with a stronger dollar and high US dollar yields, gold is going to continue to stay under quite a lot of pressure now," Mr Halley added.

Spot gold may find support in a zone of $1,204-$1,210 per ounce and bounce moderately before falling, as suggested by its wave pattern and a Fibonacci ratio analysis, according to Reuters technical analyst Wang Tao.
