SINGAPORE, April 21 (Reuters) - Bullion powered to a lifetime high for a fifth consecutive session on Thursday on a sharply weaker dollar, while lingering tensions in the Arab World, worries about the euro zone crisis and U.S. fiscal health offered additional support.
Silver roared to its highest in more than three decades as it tracked a rally in gold, which was also spurred by a threat of a downgrade to the United States' triple-A credit rating. The gold-silver ratio -- the number of silver ounces needed to buy an ounce of gold -- was at its lowest since 1983.
Spot gold rose to a record high of $1,508 an ounce and stood at $1,506.19 an ounce by 0243 GMT, up $8.04 an ounce. U.S. gold futures <GCcv1> also hit a lifetime high at $1,508.9 an ounce.
"The U.S. effectively lost its triple A rating in the eyes of investors that really matter quite some time ago, back when gold broke $1,000 an ounce," said Fat Prophets commodities analyst David Lennox.
"We don't think America's perceived rating will improve anytime soon and this is the driving force behind our expectation of gold's continued price strength. Our next target for gold is $1,590 an ounce."
A bullish target at $1,518 per ounce remains intact for spot gold as indicated by an inverted head-and-shoulders pattern and its wave pattern, said Wang Tao, a Reuters market analyst for commodities and energy technicals.
Spot silver rose as high as $45.93 an ounce, its strongest since 1980, when the Hunt Brothers of Texas cornered the silver market.
The dollar extended losses and struck its lowest in almost three years against a basket of currencies as the prospect that U.S. interest rates would remain at record lows prompted investors to flock back to higher-yielding currencies.
The physical market in Asia saw limited selling of scrap as investors waited for more gains. Dealers noted physical buying from India in the previous session ahead of a main religious festival, suggesting that consumers had no choice but to buy bullion at higher prices.
India, the world's largest gold consumer, celebrates Akshaya Tritiya on May 6, when consumers buy gold to invoke prosperity.
"Sentiment is still bullish, we can say. The dollar is weakening and there is no solution to the situation in Libya. There's a downgrade in U.S. rating and there's still uncertainty in the euro zone. It's messy around the world," said Ronald Leung, director of Lee Cheong Gold Dealers in Hong Kong.
"But I think gold is rising too fast. We are waiting for some kind of correction in the near future. Hopefully next week."
France promised Libyan rebels on Wednesday it would intensify air strikes on Muammar Gaddafi's forces and send military liaison officers to help them as fighting raged in Misrata. Gaddafi's government is circumventing international sanctions to import gasoline to western Libya by using intermediaries who transfer the fuel between ships in Tunisia. [
