NEW YORK, Dec 2 (Reuters) - U.S. crude futures fell 2 percent to under $77 a barrel on Wednesday, extending losses after U.S. government inventory data showed larger-than-expected builds in crude and gasoline stocks.
Crude oil inventories rose 2.1 million barrels last week, raising doubts about economic recovery in the world's top oil consuming nation, a weekly report from the U.S. Energy Information Administration showed. [
]The data also showed that gasoline stocks rose more than expected but distillate supplies fell more than forecast.
"Sluggish demand for gasoline and refined products coupled with anemic demand for crude from refineries, which pushed the utilization rate below 80 percent, is an indicator of slack in the system," Chris Jarvis, senior analyst, Caprock Risk Management, Hampton Falls, New Hampshire.
NYMEX crude for January delivery <CLc1> fell $1.54 to $76.83 a barrel by 1:24 p.m. EST (1824 GMT). Brent crude <LCOc1> fell $1.29 to $78.06.
The U.S. dollar rose against the euro and the yen on Wednesday, further pressuring oil prices. [
]A stronger dollar typically discourages investor interest in dollar-denominated commodities such as oil.
Wall Street also weighed on oil prices. U.S. stock indices were mixed, with the Dow Jones industrials and S&P 500 slipping due to concerns about financial regulations as well as the energy sector.[
]Oil has rallied from below $33 last December but has held in a narrow band of $70 to $82 over the past two months. Some analysts see little chance prices will push above the range, given ample supplies and little sign of strengthening demand.
Globally, signs of oil demand were mixed. In India, annual oil product sales rose 17.3 percent in October, fueled by economic activity and higher farm sector demand, according to government data.[
]China and India will be responsible for most of the world's oil demand growth in the next two decades, according to an International Energy Agency forecast last month.
However, in Russia, there were further signs of rising global oil supplies as the nation's Energy Ministry data showed output hit a post-Soviet record for the fourth straight month, retaining its position as the world's top producer ahead of Saudi Arabia. [
