NEW YORK, Jan 25 (Reuters) - Oil prices fell on Tuesday on a surprise slip in Britain's fourth-quarter economic growth and after India raised interest rates in an attempt to cool inflation, fueling concerns about the rate of economic recovery and high commodity costs.
Early pressure on oil came from a stronger dollar, though the dollar index <.DXY> seesawed with the euro <EUR=> on Tuesday. [
] A stronger dollar can pressure dollar-denominated oil because it raises prices to consumers using other currencies, lifts the value of greenbacks to producers and attracts investment into other markets.U.S. crude futures, on track to end lower a sixth consecutive day, found technical support above $86 a barrel, ahead of weekly oil inventory reports, starting with industry's data set to arrive late on Tuesday.
U.S. crude oil for March delivery <CLc1> fell $1.46, or 1.66 percent, to $86.41 a barrel at 11:33 a.m. EST (1633 GMT), trading as low as $86.30, its lowest since prices fell to $86.27 on Dec. 2. Tuesday's intraday high was $87.85.
The 100-day moving average for the U.S. March contract was at $86.13, also providing some technical support.
In London, ICE Brent crude for March <LCOc1> fell $1.07 to $95.54 a barrel, trading from $94.75 to $96.68.
Total Brent trading volume was at 423,600 lots traded, according to Reuters data, 10 percent above the 250-day average.
Total U.S. crude volume was above 437,000 lots traded near midday in New York, 36 percent under the 250-day average.
"Maybe, just maybe there are still risks in this global economy of ours. Oil prices took a drop ... on news that U.K. gross domestic product fell 0.5 percent in the three months through December," Phil Flynn, analyst at PFGBest Research in Chicago said in a note.
Britain's economy suffered a 0.5 percent contraction in fourth-quarter 2010 after December's heavy snow took a harsher toll than economists had forecast. [
]Also weighing on oil, India's central bank raised interest rates to clamp down on inflation and warned of higher food prices unless steps are taken to boost stocks. [
]U.S. economic data was mixed. The nation's consumer confidence improved more than expected in January to its highest level in eight months. [
]But a separate report showed U.S. home prices fell again in November, the Standard & Poor's/Case-Shiller index said, although the drop was not as sharp as expected. [
]Brent crude's premium over U.S. benchmark West Texas Intermediate (WTI) crude <CL-LCO1=R>, seesawed, but hovered near $9 a barrel after reaching a $9.76 peak Monday.
"The WTI forward curve has steepened further at the front end, because the front-month futures contract has come under greater pressure than the contracts thereafter," Commerzbank analysts said in a note.
U.S. OIL INVENTORY DATA EYED
The high U.S. crude inventories, especially at the Cushing, Oklahoma, delivery point for the U.S. crude contract, have helped keep U.S. crude prices below Brent.
U.S. crude oil inventories were expected to have risen last week as imports increased, a Monday Reuters poll of analysts showed ahead of data from industry group the American Petroleum Institute due at 4:30 p.m. EST (2130 GMT) on Tuesday. [
]Crude stocks were forecast to be up a second straight week, with gasoline stockpiles also seen higher. Distillate stocks, which include diesel fuel and heating oil, were expected to be lower on increased heating fuel demand.
The report from the U.S. Energy Information Administration is due on Wednesday at 10:30 a.m. EST (1530 GMT). (Additional reporting by Zaida Espana in London and Florence Tan in Singapore; Editing by Marguerita Choy)
