Dec 3 (Reuters) - Gold gained 1 percent on Monday to hit its highest in more than three weeks, boosted by a sell-off in the dollar after the United States and China agreed to hold off on fresh trade tariffs for 90 days.
Meanwhile, palladium soared to a record, putting it just about $12 short of parity with gold.
Spot gold was up 0.88 percent at $1,232.69 per ounce at 13:09 p.m. EST (1809 GMT), having touched its highest level since Nov. 7 at $1,234.87.
U.S. gold futures gained 1 percent to $1,238.10.
"Mainly it's the weakness in the dollar today. ... Dollar was down with respect to most of the currencies as a result of the outcome, at least what we call it as a positive outcome, from the G20 meeting between U.S. and China," said Jeff Klearman, portfolio manager at GraniteShares.
"It wasn't the most positive outcome that could have occurred but it was positive in the sense there is negotiations and freeze on the tariffs applied. That has helped to weaken the dollar and support the metal."
The U.S. and Chinese presidents, during their meeting on the sidelines of the Group of 20 summit in Argentina, agreed not to impose additional trade tariffs for at least 90 days while they hold talks to resolve existing disputes.
This encouraged investors to sell the dollar, making gold cheaper for holders of other currencies.
"The U.S.-China trade cease-fire gave traders and investors a double-barrel shot of upbeat news, following last week's surprisingly dovish comments coming from U.S. Federal Reserve Chairman Jay Powell," Kitco Metals senior analyst Jim Wyckoff said in a note.
"The U.S. dollar index is weaker as secondary world currencies were boosted, including the Chinese yuan, on the U.S.-China truce. That's a bullish outside market force for the metals markets."
The U.S. currency had been the preferred safe haven this year as the U.S.-China trade conflict unfolded against a backdrop of higher U.S. interest rates, denting gold's appeal.
"Bullion is likely to get a further boost if prices manage to stand firmly above $1,230 and particularly if they surpass $1,235," ActivTrades' chief analyst Carlo Alberto De Casa wrote in a note.
"A climb would become more likely if the Fed reduces the number of rate hikes in 2019/20."
Lower interest rates reduce the opportunity cost of holding non-yielding bullion and weigh on the dollar.
Among other precious metals, palladium gained 2.67 percent to $1,209.50 an ounce. It registered its highest on record at $1,221.95 earlier in the session.
The metal, mainly used in emissions-reducing auto catalysts for vehicles, has risen about 15 percent so far this year.
"It looks like there will be a breakthrough with China and the tariffs, which could translate into more demand moving forward, especially in cars," said Bob Haberkorn, senior market strategist at RJO Futures.
U.S. President Donald Trump on Monday said China had agreed to cut import tariffs on American-made cars.
