NEW YORK, July 30 (Reuters) - U.S. crude prices slipped on Friday, pressured by data showing economic growth in the United States slowed in the second quarter and gloomy consumer sentiment.
But a report of positive business activity in the U.S. Midwest and another showing a better leading indicator index helped pull oil prices off their lows.
U.S. crude for September <CLc1> delivery fell 20 cents to $78.16 a barrel at 1 p.m. EDT (1700 GMT), having traded from $76.83 to $78.45.
ICE Brent edged down 121 cents to $77.47 a barrel, having traded as low as $76.20.
U.S. economic growth slowed in the second quarter and the pace of consumer spending eased, fueling concerns about the recovery in the rest of 2010. [
]Gross domestic product expanded at a 2.4 percent annual rate, just under expectations, after a revised 3.7 percent growth pace in the first quarter.
"We were already down following the equities market that was already low even before the GDP report came out," said Addison Armstrong, analyst at Tradition Energy in Stamford, Connecticut.
"The market has good technical resistance, currently below $79. Support is down to $76.50...."
Consumer sentiment dropped in July to a nine-month low, according to Thomson Reuters/University of Michigan's Surveys of Consumers, adding to the economic concern. [
]But another report showed business activity in the U.S. Midwest region expanded more than expected this month on strong orders. The Institute for Supply Management-Chicago business barometer rose to 62.3 from 59.1 in June. [
]Also seen helping ease the gloom, the Weekly Leading Index, a measure of future U.S. economic growth, rose in the latest week, though its annualized growth rate fell, the The Economic Cycle Research Institute said on Friday. [
]The mixed data and stronger earnings helped Wall Street bounce off its lows. [
] While the euro <EUR=> weakened against the dollar, the greenback hit multimonth lows against the Japanese yen and the dollar index <.DXY> was lower.A weak dollar often supports prices for dollar-denominated oil, making it cheaper for buyers using other currencies and lowering the value of the dollars producers receive.
Another supportive factor on Friday was the presence of two tropical weather systems in the Atlantic Basin. They still were being given low chances of strengthening into tropical depressions over the next 48 hours by the U.S. National Hurricane Center on Friday. [
]"There is always a reluctance to be too short and then come back after the weekend and there is a real storm threat," said Phil Flynn, analyst at PFGBest Research in Chicago.
DEMAND CONCERNS AND RISING INVENTORIES
Signs of tepid economic recovery and oil demand growth, along with the hefty inventories have helped keep oil prices in check as they recovered from a low under $65 in late May.
Japanese oil product demand fell 4.7 percent in June from a year earlier, declining for a second straight month. [
] Industrial output in Japan unexpectedly fell in June and manufacturers expect further declines in coming months. [ ]U.S. oil demand in May was revised down by 4.21 percent, the U.S. Energy Information Administration said on Thursday. [
] On Wednesday, the EIA reported a sharp build of in crude oil stockpiles last week, more than 7 million barrels, along with rising stocks of gasoline and distillates. [ ] (Additional reporting by Selam Gebrekidan, Alex Lawler and Alejandro Barbajosa; Editing by John Picinich)
