SINGAPORE, March 16 (Reuters) - Gold regained strength on Wednesday after falling to a 1-month low in the previous session, but declines in ETF holdings to their lowest in 10 months suggested that speculators could still sell bullion to raise liquidity if equities reversed gains.
Investors closely watched a nuclear crisis in Japan triggered by a deadly earthquake on Friday, but the physical market slowed to a trickle after bargain hunting resurfaced at lower levels, putting pressure on premiums.
Workers were ordered to withdraw briefly from a stricken Japanese nuclear power plant on Wednesday after radiation levels surged, a development that suggested the crisis was spiralling out of control.
Spot gold added $6.05 an ounce to $1,400 an ounce by 0657 GMT, having fallen as low as $1,380.90 an ounce on Tuesday, its weakest since mid-February. Gold was trading below the 25-day moving average around $1,403.
"I think sentiment is a bit mixed now. We don't know yet how the nuclear crisis will affect the world. Everything seems to stop in Japan, so the economy will deteriorate. We don't know whether if will affect other areas," said Ronald Leung, director of Lee Cheong Gold Dealers in Hong Kong.
"We heard there was some physical buying at about $1,390," said Leung, adding that jewellers had deserted the physical market at current price levels.
Premiums for gold bars in Hong Kong were offered from as little as 90 cents to the spot London prices to as high as $1.70, reflecting an illiquid market.
The world's largest gold-backed exchange-traded fund, SPDR Gold Trust , said its holdings fell further to 1,212.745 tonnes by March 15, their lowest since May of last year, from 1,213.655 tonnes on March 14.
Silver steadied, having dropped to its lowest level since late February on Tuesday.
Platinum failed to sustain an early rebound and slipped to its weakest since December on worries the crisis in Japan could affect demand in auto catalytic converters. Sister metal palladium also gave up early gains.
Japan's major car plants were shut following Friday's devastating earthquake, in which officials say at least 10,000 people were killed, and remain closed as power supplies are disrupted and companies struggle to gather information amid the chaotic situation in the country.
Asian financial markets rallied on Wednesday, with Tokyo stocks rebounding 5.7 percent after a steep two-day sell-off on Japan's killer earthquake and unfolding nuclear crisis.
U.S. gold futures for April rose $8.8 an ounce to $1,401.6 an ounce.
Premiums for gold bars were unchanged at $1 an ounce to the spot London prices in Singapore, a centre for bullion trading in Southeast Asia.
"I guess supplies are still limited and many people do not want to take delivery if the destinations are far away. They fear the price will bounce back further," said a dealer in Singapore.
"It's a very tricky situation. Last night, we even saw buy orders at $1,380, so everyone just trembles when there's the slightest ripple in the market."
The yen edged lower on Wednesday, taking its cues from a short-covering bounce in Tokyo shares, but may see more gains near-term as jitters about Japan's nuclear crisis keep investors on edge and risk appetites subdued.
Since the massive earthquake and tsunami hit Japan, the yen has risen partly on expectations Japanese insurers and companies will repatriate funds to help pay claims and reconstruction costs. But fears of intervention by Japanese authorities to weaken the yen has limited its upside so far.
Brent crude rose $1 towards $110 after Bahraini security forces attempted to clear protesters on Wednesday, rebounding from a three-week low near $107 earlier in the day.
