NEW YORK, April 17 (Reuters) - Oil prices rose over $50 a barrel on Friday on news of a rebound in U.S. consumer confidence and better-than-expected quarterly earnings.
However, a nearly 19-year high in crude oil inventories, a stronger dollar and continuing worries about the economic outlook kept a cap on prices.
U.S. crude oil futures <CLc1> were 58 cents higher at $50.56 a barrel by 12:58 p.m. EDT (1658 GMT). ICE Brent crude <LCOc1> rose 2 cents to $53.08.
"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.
"Some of the more positive results from Citigroup and General Electric are giving optimism that maybe things are turning around and that is helping to bolster buying in crude."
Citigroup <C.N> and General Electric <GE.N> reported better-than-expected earnings for the first quarter of 2009. [
]Oil was also buoyed by a survey showing that U.S. consumer confidence rebounded in April to the highest levels since September.[
]Prices eased from gains of more than $1 earlier as U.S. stocks turned negative as news of Citigroup's better-than-expected first quarter performance was tempered by comments from the company indicating that consumer credit deterioration continues to be a concern.[
]Oil has hovered around $50 for most of this month and gains have been limited by weak demand and rising crude stocks, which in the United States have reached their highest level in nearly 19 years.[
]The $50-a-barrel level is also key in that members of the Organization of the Petroleum Exporting Countries have said it is a good compromise price given the weakness of the global economy.
"OPEC may have to do more at their meeting next month but until then, I think they are happy with $50 a barrel," Bentz said.
The producer group has argued prices need to be higher to support investment for the long-term, but for the near-term, it is mindful of the need to nurse oil-consuming nations back to economic health.
Oil is around $100 below a record high of $147.27 a barrel last July, but OPEC's action to limit supplies has helped to pull the market back from a low of $32.40 in December.
Industry observers and analysts have estimated OPEC has delivered around 80 percent of its agreements to reduce output by 4.2 million barrels per day from last September.
They have also said it could struggle to tighten output much more.
Monthly crude allocations have shown leading exporter Saudi Arabia has cut supplies to some of its customers for May, but Nigeria and Angola have added extra cargoes to their April and May loading schedules, traders said.
