NEW YORK, June 11 (Reuters) - U.S. oil prices fell more than 2 percent on Friday as reports of an unexpected fall in May retail sales in the United States and easing industrial output in China revived concerns about the economy.
Prices fell sharply after the U.S. Commerce Department reported that total retail sales fell 1.2 percent in May, the first decline since September, after April's upwardly revised 0.6 percent rise. [
]Crude prices briefly pared losses on news that U.S. consumer sentiment improved in early June to its strongest level in nearly 2-1/2 years. [
]At 12:30 p.m. EDT (1630 GMT), U.S. crude for July <CLc1> was down $2.11, or 2.8 percent, at $73.37 a barrel, trading in a range from $73.30 to $75.64. A lower finish would snap a string of three higher closes.
ICE Brent <LC0c1> was trading down $1.63 at $73.66.
"The retail sales number put a damper on things and the report on Chinese inflation had already helped pull oil back," said Robert Yawger, senior vice president, energy futures at MF Global in New York.
Chinese inflation quickened to a 19-month high in May, and some analysts said China needs to stave off the risk of overheating by raising interest rates and letting the yuan strengthen. [
]The U.S. retail sales report weighed on the Dow Jones Industrials and the S&P 500 stock indexes on Friday, though the better-than-expected read on consumer sentiment and technology sector strength had lifted the Nasdaq. [
]The consumer sentiment report helped the dollar strengthen against the yen and euro. [
]A stronger dollar can pressure oil prices by making it more expensive for consumers using other currencies and also pulling investors from energy into foreign exchange markets.
Most analysts expect the pace of fuel demand recovery in the euro zone to slow, making the market more reliant on China to drive growth but hindering China's ability to play that role.
On Thursday, a report of a 48.5 percent surge in Chinese exports in May helped oil prices surge 2 percent.
The International Energy Agency also revised its 2010 oil demand growth forecast slightly higher in a report on Thursday, adding to the bullish sentiment in the market after a government oil inventory report showed lower crude stockpiles.
But Friday's data showing China's industrial output slowed in May from April, fueled concerns that economic growth in the second largest energy consumer may slow. [
]"We are currently stabilizing towards the top end of the recent range but it seems to be having trouble getting higher than this," said Christopher Bellew of Bache Commodities.
"Sentiment is still fairly fragile and people are worried about the depth of the European crisis."
At near $75 a barrel, oil prices are now in the middle of what Saudi Arabia's oil minister calls the "ideal realm" between $70 and $80 a barrel.
But prices are still nearly 15 percent below the 19-month high of $87.15 touched in early May.
MF Global's Yawger and other sources noted that Friday's early $75.64 intraday high was near $75.70, where technical resistance was expected, at the 50-percent retracement of the drop from the May 3 $87.15 high, a 19-month peak, to the $64.24 low on May 20, the day the June contract expired.
