NEW YORK, Aug 11 (Reuters) - Oil prices fell a second straight day on Wednesday, weighed down by rising U.S. refined products inventories and cautious economic outlooks that also pressured equities markets.
Refined products inventories rose more than expected in the week to Aug. 6 despite a sharp 3.1 percentage point drop in refinery utilization, the U.S. Energy Information Administration reported. [
]Gasoline inventories rose 400,000 barrels, more than expected, leaving the premium to year-ago levels at 11.5 million barrels. U.S. gasoline futures tumbled more than 3 percent, dipping briefly below $2 a gallon for the first time since July 7.
U.S. crude for September <CLc1> delivery fell $1.90, or 2.37 percent, to $78.35 a barrel at 1:31 p.m. EDT (1731 GMT), having traded from $77.90 to $80.40.
September RBOB gasoline <RBc1> fell 7.78 cents, or 3.73 percent, to $2.0075 a gallon, trading as low as $1.9942.
Front-month ICE Brent crude <LCOc1> fell $1.74 to $77.86 a barrel.
"One thing to take from the report was the larger-than-expected gain in products despite lower refinery rates, which shows how poor demand is in the United States," said Mike Zarembski of OptionsExpress in Chicago.
The EIA also reported a 3.5 million barrel increase in distillate stocks. This more than overshadowed the potentially bullish news of a 3 million barrel fall in crude inventories.
Oil already was under pressure after Tuesday's downbeat economic outlook from the Federal Reserve, Wednesday's cautious take on the economy from the International Energy Agency and reports showing slower economic growth and slipping Chinese oil demand growth.
The IEA monthly report slightly increased its forecasts for global crude demand for 2010 and 2011, but warned any rise in fuel consumption could be wiped out if the global economy proved weaker than expected, [
]The dollar rallied against most currencies, while falling to a 15-year low against the yen, as the gloomy outlook from the Federal Reserve and slower Chinese factory growth dented risk appetite. [
]CHINA GROWTH SLOWS
Growth in Chinese investment and factory output slowed further in July as the government slowed credit growth after a record lending spree in 2009. [
]While China's implied oil demand rose a modest 2.2 percent in July from year ago, it fell 6 percent from June. [
]On a more hopeful note, China's apparent crude oil demand should rise 11 percent this year, state media reported, citing a China Petroleum and Chemical Industry Federation forecast. [
]STORM WATCH
The market did not receive any support from Tropical Depression Five in the eastern Gulf of Mexico. It was expected to hit eastern Louisiana as a tropical storm Thursday night, the U.S. National Hurricane Center said. [
]As of Wednesday, there had been no reports of oil or natural gas output cuts or full platform evacuations in the Gulf of Mexico due to the tropical weather threat, according to the U.S. Bureau of Ocean Energy Management. [
