* U.S. Fed Chair Jerome Powell to testify on economic outlook
* Holdings in SPDR Gold Trust dip to lowest since Sept. 20
Nov 13 (Reuters) - Gold prices rose on Wednesday after a speech by U.S. President Donald Trump dashed hopes for a positive sign on a U.S.-China trade deal, prompting investors to seek safety in the metal.
Spot gold rose 0.4% to $1,462.15 per ounce by 0628 GMT, while U.S. gold futures advanced 0.7% to $1,463.30 per ounce.
Asian stocks and Wall Street futures fell as growing worries that trade talks are stalling and concern about intensifying unrest in Hong Kong hurt demand for risky assets.
U.S. and Chinese negotiators were "close" to a "phase one" trade deal, Trump said in Tuesday's speech to the Economic Club of New York, but offered no new details on negotiations.
"The downtrend (in gold) has paused. President Trump, on one hand, said the deal was close and, on the other hand, said he will raise the tariffs if a deal is not reached," said Michael McCarthy, chief market strategist at CMC Markets.
"This didn't help the trade situation but supported gold."
Gold, considered a safe store of value during economic and political uncertainty, has risen about 14% this year on concerns over the trade war and monetary policy easing by central banks.
"As long as things (trade deal) are not stamped and sealed, uncertainty is going to prevail in the market and gold will receive support," said Ajay Kedia, director at Kedia Advisory in Mumbai.
Later on Wednesday, Fed Chairman Jerome Powell is set to testify on the economic outlook before the congressional Joint Economic Committee.
Political unrest in the Asian financial hub of Hong Kong provided support for the precious metal, as police battled pro-democracy protesters at several university campuses in the Chinese-ruled city.
"Slowing economic growth, geopolitical risk and an easing interest rate cycle remain the reality," ANZ Bank said in a note. "And such a backdrop should support gold investment demand through 2020."
Meanwhile, holdings of the world's largest gold-backed exchange-traded fund SPDR Gold Trust fell to their lowest since Sept. 20 on Tuesday.
Palladium was up 0.5% at $1,708.20 an ounce. The autocatalyst metal climbed to a record $1,824.50 last month and was trading at a premium of about $250 to gold on Wednesday.
"Palladium should hold its premium over other metals, amid a sustained deficit backdrop," ANZ said. "Stricter emission regulations are driving palladium demand, despite the struggling auto sector."
Silver rose 1% to $16.94 per ounce, and platinum gained 0.8% to $875.18. (Reporting by Sumita Layek and Diptendu Lahiri in Bengaluru; Editing by Sherry Jacob-Phillips and Subhranshu Sahu)
