* Speculators sell gold to cover losses

SINGAPORE, March 15 (Reuters) - Gold slipped half a percent on Tuesday as declines in stock markets triggered by a deepening nuclear crisis in Japan prompted speculators to sell bullion to cover losses, while holdings on the ETF slipped to their lowest since May last year.
Japanese stocks dropped 7 percent to a two-year low and futures prices plunged as the country's prime minister said radiation levels at a stricken nuclear plant had become high, deepening concerns about the economic toll of the disaster.
Gold lost $6.95 an ounce to $1,419.70 an ounce by 0328 GMT, after rising as much as 1 percent on Monday as Japan battled to prevent a nuclear catastrophe after last week's devastating quake and tsunami and on political unrest across the Arab World.
"It still looks like it's constructive. It's just consolidating. But if we get a large sell-off in equities, people will tend to sell gold," said Jonathan Barratt, managing director of Commodity Broking Services in Melbourne.
"But if it's a major concern, then people will eventually go to gold as the last resort."
Premiums for gold bars were steady at between $1 and $1.5 an ounce to the spot London prices in Hong Kong and Singapore, with no signs of safe haven buying related to last week's massive earthquake in Japan and the subsequent nuclear crisis.
Quake-hit Japan faces a recovery and reconstruction bill of at least $180 billion, or 3 percent of its annual economic output, or more than 50 percent higher than the total cost of 1995's earthquake in Kobe.
"The price shot up to above $1,430 but it could not break through that level. I think that's why the market is down. Also, ETF holdings seem to be going down again," said a dealer in Singapore. "We can say people are selling gold to cover their margin call."
U.S. gold futures for April fell $5 to $1,419.9 an ounce.
In the Middle East, the United States urged Saudi Arabia on Monday to show restraint after it sent troops to neighboring Bahrain in a move some analysts said showed the limits of Washington's influence in the region.
The deployment of 1,000 Saudi troops, at the request of Bahrain's Sunni royal family, came two days after U.S. Defense Secretary Robert Gates visited the island kingdom and pressed its rulers to implement political reforms to defuse tensions with the Shi'ite Muslim majority.
Rising tension in the North Africa and the Middle East helped bullion struck record around $1,444 last week.
In other markets, the dollar briefly spiked against the yen on Tuesday and stirred talk Japanese authorities may have intervened to stem a rising yen, but traders later downplayed the move as a one-off order that added to nervousness in the market.
The Bank of Japan said on Monday it would increase the size of its asset purchase to 10 trillion yen ($122 billion) from 5 trillion yen and analysts think it may take more steps if the economic outlook deteriorates further.
The BOJ is even more dovish than the U.S. Federal Reserve, which has been cautious about seeking to exit its stimulus policy as it wants to bring down unemployment
U.S. Federal Reserve policymakers meet on Tuesday and investors will closely watch the Fed's assessment on unemployment and the economy in general.
