LONDON, April 21 (Reuters) - Gold prices hit record highs for a fifth session on Thursday and silver rallied to its strongest since 1980 as the dollar slid to a three-year low against a basket of major currencies and oil prices rallied.
The action in the oil and currency markets is adding fuel to a rally sparked by concerns over the U.S. economic outlook, rising inflation, worries over euro zone debt and historically low interest rates in the United States, analysts said.
"On the basis of everything that is going wrong -- a possible downgrade in the United States, the situation in Libya not getting any better, the general feeling about the global economic situation -- I think gold is going to go higher," said London-based ANZ Bank analyst Peter Hillyard.
"Gold isn't finished yet by a long shot."
Spot gold <XAU=> was bid at $1,507.19 an ounce at 0853 GMT, against $1,498.15 late in New York on Wednesday, having earlier peaked at $1,508.50 an ounce. U.S. gold futures for June delivery <GCv1> rose $9.40 an ounce to $1,508.30.
Silver <XAG=> was bid at $45.92 an ounce against $45.20.
Gold prices have risen 5.4 percent so far this month and are on track for a sixth straight week of gains, reflecting strength across the commodity markets. The Reuters-Jeffries CRB index <.CRB>, a global benchmark for commodities, posted its biggest one-day rise in a fortnight on Wednesday.
Many have been helped by losses in the dollar, which slid to its lowest since early 2008 against a basket of major currencies on Thursday. [

TIGHTER POLICY EYED
A tightening of U.S. monetary policy and eventual rise in interest rates are still viewed as the biggest risk factors for gold, which as a non-interest bearing asset has a lower opportunity cost when rates are depressed.
But for the moment the precious metal is proving resilient above $1,500 an ounce.
"We still expect dips to be viewed as buying opportunities, with gold and silver viewed favourably by investors seeking to hedge against inflation and debt jitters," said FastMarkets analyst James Moore.
On the supply side of the market, African Barrick Gold <ABGL.L> said its output fell 2 percent year-on-year in the first quarter, but said it was on track to meet its full-year production target. [
]Gold is much less a hostage to traditional supply and demand fundamentals than commodities that are physically consumed like oil, but these factors can still have an impact on price.
"An ongoing supply/demand imbalance underpins the market as good demand for gold jewellery and investment bars and coins in Asia outweighs mine supply," said Fairfax analyst John Meyer.
Investment demand for silver remained strong, with holdings of the world's largest silver-backed exchange-traded fund, the iShares Silver Trust <SLV>, rising by nearly 67 tonnes on Wednesday to 11,183.69 tonnes. [
]Silver has outperformed gold this year, rising 49 percent. The gold:silver ratio, or the number of silver ounces needed to buy an ounce of gold, fell to a 28-year low at 32.9 on Thursday.
Among other precious metals, platinum <XPT=> was at $1,811.24 an ounce against $1,791.15, while palladium <XPD=> was at $766.38 against $767.97.
Anglo Platinum <AMSJ.J>, the world's number one producer of the precious metal, kept its full-year production target on Thursday despite a 5 percent fall in first-quarter output attributed to safety stoppages. [
