(Updates prices, adds closing in Tokyo)

SINGAPORE, Feb 21 (Reuters) - Gold roared to a record on Thursday as crude oil rose above $100 a barrel, while platinum jumped to an historic high on speculative buying driven by supply fears in main producer South Africa.
Not to be outdone, palladium hit a 6-1/2-year high and silver rallied to its best level in 27 years, reflecting renewed buying interest from funds and speculators in precious metals.
Gold <XAU=> hit a high of $948.60 an ounce, up from $934.80/935.60 an ounce late in New York on Wednesday, also driven by a struggling U.S. dollar.
"There's been a movement of investment funds from other asset classes to commodities again, and I think gold has benefited from that move," said Darren Heathcote of Investec Australia in Sydney.
"There's still a fair bit of safe-haven demand. Gold is receiving support from several angles at the moment," he said.
Oil <CLc1> climbed back above $100 on Thursday, about a dollar off record-highs, on hedge fund inflows and OPEC supply concerns, with traders weighing U.S. economic worries against hopes of more Fed cuts. [
]The dollar was little changed against the yen and the euro, hit by expectations the Federal Reserve will keep slashing interest rates to prevent the U.S. economy from suffering a sharper downturn. [
]In theory, high oil prices elevate gold's appeal as hedge against inflation, while a weaker dollar lifts the metal's allure as an alternative investment.
U.S. gold futures also hit record high. The active gold for April delivery <GCJ8> on the COMEX division of the New York Mercantile Exchange rose as high as $952.4 an ounce.
Jewellers in Indonesia and Vietnam cashed in on gold's rally, keeping gold bars on par with the spot London prices in Singapore <GOLD/ASIA1>.
Spot platinum <XPT=> rose to record high of $2,182/2,192 an ounce, from $2,120/2,130 an ounce late in New York.
Platinum has surged more than 40 percent this year after mines in South Africa, which account for 80 percent of the world's supply, ground to a halt for five days at the height of last month's power crisis.
"The momentum is back. Gold has broken out of the consolidation phase. The potential upside is definitely $1,000 in the first quarter," said William Kwan of Phillip Futures in Singapore.
"Most of those investors are afraid they won't be having enough precious metals: gold, silver and platinum. So they are buying ahead," said Kwan, who pegged the upside target for platinum at $2,200.
Japanese platinum futures rose but were off record highs, with new margin rules having no impact on speculative buying which have driven prices up.
The most active December contract <0#JPL:> on the Tokyo Commodity Exchange ended by the daily 240 yen per gram limit to 7,205 yen, having fallen to as low as 6,901 yen on Wednesday.
"I don't think an increase of margin will stop this type of speculation. Ultimately, they are still buying," said Kwan of Phillip Futures.
TOCOM raised margins by 50,000 yen per contract for all new positions and existing positions for all six platinum futures contracts from Thursday until the end of the month to cope with rising volatility.
Palladium <XPD=> hit a high of $505 an ounce, its highest level in more than six years, to track strong platinum prices. The metal was last quoted at $481/484 an ounce in New York.
Silver <XAG=> hit a bid high of $18.00 an ounce, its best level since December 1980, up from $17.76/17.81 an ounce, reflecting firm gold prices.
