HONG KONG, Feb 27 (Reuters) - The dollar sank to a record low against the euro on Wednesday, breaking the psychologically important $1.50 level, while Asian stocks rose for a third straight session as a $15 billion share buyback plan by IBM boosted investor confidence.
The dollar hit an all-time low against a basket of currencies a day after U.S. consumer sentiment was reported to have sunk to a five-year low, offering more proof that the world's largest economy is struggling.
The report, along with recent weak retail sales and manufacturing data, has reinforced expectations that the U.S. Federal Reserve will have to cut interest rates further, pressuring the dollar.
The slumping greenback sparked a further rally in commodities and metals. Oil remained above $101 a barrel -- a level it broke for the first time on Tuesday -- while gold surged to a record high, driven as well by a search for a hedge against inflation.
In early Asian trade, the euro <EUR=> surged as high as $1.5050 on electric platform EBS, its highest level since the single currency was introduced in 1999. By 0150 GMT it had pulled back slightly to $1.4992.
"We've just gone through a major psychological level, so the market is considering where the euro's next ceiling will be," said Hideaki Inoue, a forex manager at Mitsubishi UFJ Trust and Banking in Tokyo.
Broad weakness in the U.S. currency pushed the dollar index <.DXY> to a record low 74.509, but the dollar was little changed against the yen at 107.30 yen <JPY=>.
Federal Reserve Vice Chairman Donald Kohn said on Tuesday that a weak U.S. economy was a bigger worry than higher inflation risks, suggesting a willingness to cut the federal funds rate as the central bank tackles "difficult times".
Reports on Tuesday showed U.S. producer price inflation in January surged to its highest in more than 26 years, sparking fears of stagflation -- when prices continue to rise despite cooling economy growth. [
]For clues into the Fed's outlook on rates, investors were awaiting testimony from Fed Chairman Ben Bernanke later in the day to the House of Representatives Financial Services Committee.
Asian stock markets largely ignored the grim U.S. economic data, focusing instead on the IBM buyback plan and signs of easing credit worries.
Financial shares posted some of the biggest gains on growing confidence about the stability of U.S. bond insurers after Moody's confirmed its credit rating on MBIA Inc, while higher oil prices boosted the energy sector.
The market has worried that downgrades of bond insurers could force them to sell off the debt they have guaranteed, potentially leading to further writedowns in the global financial sector and worsening a global credit squeeze.
The MSCI's index of Asian stocks outside Japan <.MIAPJ0000PUS> rose 1.2 percent by 0200 GMT, after having climbed 2 percent over the previous two sessions. Hong Kong rose 2 percent, while South Korea addded 0.7 percent.
Japan's Nikkei index <
> rose 1.4 percent, with Mizuho Financial Group leading financials with a gain of 3 percent.Technology shares such as LG Electronics Inc <066570.KS> and Sony Corp <6758.T> were also among the day's leaders, buoyed by the IMB announcement. Its $15 billion share buyback plan is equivalent to 10 percent of its market capitalisation.
Also on Tuesday, Hewlett-Packard's <HPQ.N> chief executive Mark Hurd said the computer and printer maker "feels good" about the quarterly guidance it had provided last week, which were above Wall Street expectations, citing strong growth outside the United States. [
]OIL, GOLD AT RECORDS
Oil extended its rally, benefitting from the slumping dollar. Analysts also cited growing fuel demand and expectations that the OPEC cartel will not increase production at its meeting in early March as other key factors.
U.S. crude futures <CLc1> rose 33 cents to $101.20 a barrel, not far off a record $101.43 hit in U.S. trade on Tuesday.
The weakening dollar also sparked a rally in commodities and metals. Gold <XAU=> roared to a historic high of $955.70 an ounce, well above the $946.60/947.40 seen in late U.S. trade. Bullion prices have risen more than 14 percent so far this year.
Silver spot prices <XAG=> rose to $18.97/19.02 from $18.65/18.70 late in New York on Tuesday, trading at its highest levels since December 1980, while palladium <XPD=> hit a 6-
