NEW YORK, May 27 (Reuters) - Oil prices fell sharply and the dollar rose on Tuesday, easing inflation fears and helping a tech-led rebound in U.S. equity markets as investors bet cheaper crude will revive consumer and business spending.
A 2.6 percent drop in oil prices to almost $128 a barrel was welcomed by stock market investors after crude hit a record above $135 last week, a spike that fanned worries about inflation and the outlook for corporate profits.
The dollar rose broadly after a report showed U.S. new home sales unexpectedly climbed in April, while soft data out of Europe raised concerns over the relative health of the euro-zone economy.
U.S. crude <CLc1> traded down $4.01 to $128.18 a barrel in late post settlement trade, after settling down $3.34 at $128.85. London Brent crude <LCOc1> settled down $4.06 at $128.31 a barrel.
Persistently high energy prices kept investors wary about the prospects for inflation, which pushed U.S. Treasury debt prices lower and sidelined investors in European stocks.
Europe's stocks opened weaker amid concerns that rising inflation would add potential credit-related problems in the banking sector.
In U.S. equity markets, shares of consumer-oriented companies, including retailers, gained along with technology shares, even as energy companies, led by oil behemoth Exxon Mobil Corp <XOM.N>, declined in line with falling oil prices.
"Oil being down helps because people lately seem to be thinking of technology as discretionary (spending)," said Peter Jankovskis, director of research at OakBrook Investments in Lisle, Illinois. "I really think what we're doing is building a very solid base for a strong rally to end the year."
The Dow Jones industrial average <
> rose 68.72 points, or 0.55 percent, at 12,548.35. The Standard & Poor's 500 Index <.SPX> gained 9.41 points, or 0.68 percent, at 1,385.34. The Nasdaq Composite Index < > rose 36.57 points, or 1.50 percent, at 2,481.24.Leading the Nasdaq higher were shares of iPod- and iPhone-maker Apple, which jumped 2.6 percent, and a 3 percent gain in Internet research company Google Inc <GOOG.O>
International Business Machines Corp <IBM.N> led gainers on the both the blue-chip Dow and broad market Standard & Poor's 500 Index, with a gain of more than $3.12 to $127.32.
News on the economic front still pointed to a troubled housing market and waning consumer confidence.
Prices of U.S. single-family homes plunged a record 14.4 percent in March from a year earlier, while consumer confidence slumped to its lowest in 16 years in May as gasoline prices surged.
The Standard & Poor's/Case Shiller composite index of 20 metropolitan areas showed prices of previously owned homes fell 2.2 percent in March, deepening their year-on-year decline.
Separately, the Conference Board said its consumer confidence index slumped to 57.2 this month from 62.8 in April as rising gasoline costs and falling home prices made Americans increasingly nervous about current conditions and the future.
European stocks erased early gains after banking concerns resurfaced while data showing deteriorating consumer and business morale in many parts of Europe. The soft economic indicators also weighed on the euro.
The FTSEurofirst 300 <
> index of top European shares fell 0.4 percent to a month low of 1,314.42 points.Falling oil prices and a stronger dollar helped the European market pare some losses but weighed on the energy sector, making BP <BP.L> the single largest drag on the index.
Concern about inflation, fueled by the 15 percent rise in the price of oil this month, has stripped the FTSEurofirst index of all of May's gains.
"People are just increasingly concerned about the inflation risk picking up and the U.S. economy deteriorating," said Andrea Williams, head of European equities at Royal London Asset Management.
Responding to inflation concerns, the benchmark 10-year U.S. Treasury note <US10YT=RR> fell 20/32 to yield 3.93 percent. The 30-year U.S. Treasury bond <US30YT=RR> fell 34/32 to yield 4.65 percent.
The dollar rose against major currencies, with the U.S. Dollar Index <.DXY> up 0.57 percent at 72.386.
The euro <EUR=> fell 0.57 percent at $1.5684.
Gold ended 2 percent lower at the lowest level in a week on a stronger dollar and a sharp decline in oil prices.
Spot gold <XAU=> dropped as low as $903.50 an ounce and was at $907.10/908.30 an ounce by New York's last quote.
"The two key drivers have been both inflation concerns and the movements of the dollar," said Suki Cooper, a metals analyst at Barclays Capital.
In Asia stocks rebounded from Monday's dip as bargain hunters scoured the market after five days of losses.
Japan's Nikkei <
