NEW YORK/LONDON, April 27 (Reuters) - Gold prices rallied to their highest level in 2010 on Tuesday, defying a sharply stronger dollar, as the downgrades of sovereign credit ratings of Portugal and Greece triggered a flight to safety.
Economic uncertainties and fears about the viability of paper currencies also lifted gold to record highs when priced in euros, sterling, Swiss francs, and to a 2010 peak in terms of Australian dollars.
"The investors are risk averse at this point, and they are trying to flock to something that is more stable, such as gold," said David Lee, a trader at Heraeus Precious Metals Management in New York.
Rating agency Standard and Poor's slashed Greek debt to junk status on Tuesday, and also downgraded Portugal's rating, as fears of a Greek debt default grew. [
]The news sparked a global equities market sell-off, with Wall Street down 2.5 percent. [
]"There are some concerns that the euro zone might not recover until much later. People who are betting on the recovery story, which was driving up metal prices, are taking a second look," Lee said.
Spot gold <XAU=> hit a peak of $1,172.05, its highest level since Dec. 4. It was at $1,170.95 at 3:53 p.m. (1953 GMT), against $1,153.38 late in New York on Monday.
It hit record highs in euros <XAUEUR=R> at 889.53 euros an ounce, in sterling <XAUGBP=R> at 768.86 pounds, and in Swiss francs <XAUCHF=R> at 1,274.72 francs.
Standard & Poor's downgrades fanned sovereign risk fears about the entire euro zone, prompting investors to flee to the metal in fear-driven trade.
"Gold prices are rising on the back of presumably higher sovereign risks in the euro zone after the latest downgrade of Portugal ratings by S&P," said Commerzbank analyst Eugen Weinberg.
"Gold seems to be defying the traditional pattern -- stronger dollar, lower gold prices -- over the last weeks, pointing to stronger perception of gold as an alternative currency."
Concern over sovereign risk in the euro zone, chiefly debt-laden Greece, has helped gold rise nearly 7 percent this year, despite a 7 percent fall in the euro versus the dollar, which would normally weigh on gold. <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Greece is seeking help with its debts from the euro zone and the International Monetary Fund. Germany said on Monday it was ready to commit funds, but demanded Athens take painful austerity measures.
The spread between Greek and German government bond yields hit its widest in 12 years on Tuesday, showing premiums demanded by investors to hold Greek debt are rising.
SPDR GOLD TRUST HOLDINGS UP 6 TONNES
Strong investment demand took holdings of the world's largest gold-backed exchange-traded fund, New York's SPDR Gold Trust <GLD>, rose more than 6 tonnes to a record 1,146.216 tonnes as of Monday, the fund said. [
]Analysts said Greece's debt crisis could spill over to other euro zone countries despite an EU rescue package, prompting investors to put their money in safer investment alternatives, such as gold.
Traders are now awaiting the outcome of a two-day monetary policy meeting of the U.S. Federal Reserve, which starts on Tuesday. The Fed is expected to hold interest rates unchanged, but will discuss how to unwind its massive stimulus package.
