NEW YORK, April 17 (Reuters) - Global stocks and oil rose on Friday, extending a U.S. equity rally to six weeks, after improving consumer sentiment and better-than-expected results at Citigroup and General Electric bolstered hopes the U.S. economy is stabilizing.
But comments by the two icons weighed on sentiment, raising risk aversion and boosting the U.S. dollar. Citigroup indicated consumer credit deterioration remained a worry and GE suggested that fallout from commercial real estate losses may worsen.
The dollar touched a one-month high against the euro while U.S. Treasury debt prices fell on thin volume. Investors were caught between fear of new bond supply on the one hand and support from Federal Reserve buying on the other.
The rebound in U.S. consumer confidence and earnings that surprised on the upside lifted oil, even as a nearly 19-year high in crude inventories and stronger dollar kept a cap on prices.
U.S. consumers expressed more confidence in the U.S. economy than they have had since the sudden collapse of Lehman Brothers in September, the Reuters/University of Michigan Surveys of Consumers showed, giving equities a lift.
"The rate of deceleration in the economy is slowing," said David Lutz, managing director of trading at Stifel Nicolaus Capital Markets in Baltimore.
"From a macro standpoint, the reason for a lot of the drive is just that we're continuing to get data points that show things are beginning to operate very well in the credit markets."
Shares of Citigroup <C.N> dropped 9 percent to $3.65, while GE <GE.N> rose 1 percent to $12.39 after falling earlier in the session.
The Dow Jones industrial average <
> rose 5.90 points, or 0.07 percent, to 8,131.33. The Standard & Poor's 500 Index <.SPX> gained 4.30 points, or 0.50 percent, to 869.60. The Nasdaq Composite Index < > added 2.63 points, or 0.16 percent, to 1,673.07.For the week, the Dow rose 0.6 percent, the S&P 500 gained 1.5 percent and the Nasdaq rose 1.2 percent. The S&P 500 extended its rally to six straight weeks.
Banks in Europe rallied on hopes that the worst was over for the battered banking sector, lifting an index of leading regional companies to a 4.7 percent gain for the week.
The FTSEurofirst 300 <
> index of top European shares rose 1.6 percent to 814.69 points, its highest close in more than two months."What this shows, and what the market is reacting to directly is that banking is very profitable if you take out all the stupid stuff, like exotic derivatives," said David Evans, market analyst at BetOnMarkets.com.
Oil prices rose above $50 a barrel on news of the rebound in U.S. consumer confidence and the earnings reports.
However, the high crude oil inventories, the stronger dollar and continuing worries about the economic outlook kept a cap on prices.
U.S. crude oil futures <CLc1> settled at $50.33, 35 cents higher. ICE Brent crude <LCOc1> settled at $53.35, up 29 cents.
"You've got two forces kind of battling and we're basically just stuck here around $50," said Tom Bentz, senior commodity analyst at BNP Paribas Commodity Futures Inc in New York.
A speech by European Central Bank President Jean-Claude Trichet failed to dispel uncertainty about the bank's policy steps next month, weighing on the euro. The euro <EUR=> fell 1.18 percent at $1.3022.
"A little bit of risk aversion and euro weakness ... is boosting the dollar," said Paresh Upadhyaya, a portfolio manager at Putnam Investments in Boston.
"The market still remains skeptical about what this means going forward for the financial sector" despite Citigroup's results, he said.
The dollar rose against a basket of major currencies, with the U.S. Dollar Index <.DXY> up 0.96 percent at 86.02. Against the yen, the dollar <JPY=> slipped 0.03 percent at 99.24.
The strong rally in stocks eroded the safe-haven appeal in bonds.
The benchmark 10-year U.S. Treasury note <US10YT=RR> fell 30/32 in price to yield 2.95 percent. The 2-year U.S. Treasury note <US2YT=RR> fell 5/32 in price to yield 0.98 percent.
Gold fell about 1 percent on the dollar rise and stock rally, denting its appeal as an alternative investment.
U.S. gold futures for June delivery <GCM9> settled down $11.90 at $867.90 an ounce in New York.
Asian stocks rose after results on Thursday from JPMorgan and Google kept shares on track for a sixth week of gains.
The MSCI index of Asia Pacific stocks outside Japan <.MIAPJ0000PUS> edged up 0.3 percent on the day, while Japan's Nikkei share average <
> climbed 1.7 percent.
