NEW YORK, Aug 27 (Reuters) - U.S. equities rebounded on Thursday, lifted by financial stocks, while crude oil bounced off two days of declines on the turn in Wall Street sentiment.
The dollar fell to multiweek lows against the yen and euro. At the same time, commodity-linked currencies rallied as the rebound in stocks and oil prices quieted for the moment worries about the strength of the global economy. <For related news click [
]>.U.S. Treasuries slipped as the turnaround on Wall Street sapped the attraction of safe-haven government debt, even after a solid sale of government notes inspired optimism among bond investors. [
].Investors calmly digested the government's issuance of $109 billion in new Treasury bonds this week, which assuaged ongoing concerns about the burgeoning amount of U.S. debt.
Financial shares led the turnaround in equities, rising 1 percent as measured by the S&P financial index <.GSPF>, with Citigroup <C.N> gaining 9.1 percent to $5.05.
"This morning we were down 1 percent and we saw some immediate reaction from the banking sector, especially Citigroup," said Steve Goldman, market strategist at Weeden & Co in Greenwich, Connecticut. "So that helped to stem the declines."
Shares of insurance company American International Group Inc <AIG.N> soared 27 percent to $47.84.
The Dow Jones industrial average <
> closed up 37.11 points, or 0.39 percent, at 9,580.63. The Standard & Poor's 500 Index <.SPX> rose 2.86 points, or 0.28 percent, at 1,030.98. The Nasdaq Composite Index < > climbed 3.30 points, or 0.16 percent, at 2,027.73.The late afternoon rally took U.S. stocks back to levels last seen in October.
In currency markets the euro rose to a three-week high against the dollar. Low volume, typical of August, was responsible for the strength of the reversal, traders said.
"It's a late August market. People were long dollars and got squeezed when U.S. stocks recovered," said Brian Dolan, chief strategist at Forex.com in Bedminster, New Jersey.
The upbeat turn in financial markets overshadowed a growing sense among investors that recent asset price gains and optimism about a world recovery have been overdone.
"Risk assets are not rallying as they have, and there's a sense of lethargy setting in that certainly suggests enthusiasm is waning," Dolan said.
Crude oil was supported by Wall Street's rebound and losses in the dollar. [
]U.S. crude for October <CLc1> rose $1.06 to settle at $72.49 a barrel after dipping as low as $69.83 earlier in the day on worries about high commercial crude inventories and weak demand. Brent crude <LCOc1> rose 86 cents to $72.51.
"As things stand, the underlying influence of equities and the dollar remain in place," said Tom Knight, trader at Truman Arnold in Texarkana, Texas.
The $28 billion sale of seven-year U.S. government debt went well, but bonds dipped into negative territory when stocks came back from the day's lows. Earlier in the week, the government auctioned two- and five-year notes.
The benchmark 10-year U.S. Treasury note <US10YT=RR> was down 8/32 in price to yield 3.46 percent.
"People are relieved that we went through all three auctions and everything went pretty well," said Rick Klingman, managing director of Treasury trading at BNP Paribas in New York.
"But with stocks going positive there is just really no follow-through," Klingman said.
The euro rose 0.8 percent to $1.4360 <EUR=>, surging higher as a U.S. stock rebound triggered automatic buy orders against the dollar. It had fallen as low as $1.4220 earlier.
The euro was down 0.1 percent at 134.18 yen <EURJPY=>, but well off a session low of 132.94 yen.
Earlier in Europe regional shares closed lower in a choppy session after banking stocks retreated from earlier gains and chemical makers slipped. [
