LONDON, Nov 12 (Reuters) - Oil dipped below $79 a barrel on Thursday as an expected hike in U.S. crude stocks outweighed both a weak dollar near 15-month lows and an IEA report that said global oil demand will return to growth this quarter.
Delayed weekly inventories data out of the world's largest fuel consumer the United States are set to show a 700,000 barrel rise in crude stocks, a Reuters survey shows. [
]This will follow a bigger-than-expected increase of 1.2 million barrels from the American Petroleum Institute. [
]U.S. crude futures fell 48 cents to $78.80 a barrel by 0956 GMT, in a week where prices have peeped above the psychologically key $80 a barrel every day.
Brent crude futures <LCOc1> fell 39 cents to $77.56 a barrel.
The price dip came despite a report from the International Energy Agency showing that global oil demand will grow in the fourth quarter for the first time in over a year. [
]Next year oil demand is expected to average 86.2 million barrels per day, following stronger-than-expected preliminary data in North America and buoyant demand in non-OECD Asia and the Middle East, the IEA said.
The monthly report follows surveys from OPEC and U.S. government agency the Energy Information Administration that lifted oil demand growth forecasts for 2010. [
] [ ]But analysts said that traders have already factored in the more positive demand picture and that this expectation helped crude rally above $80 a barrel in recent weeks.
"Most market participants have already played the game based on a pretty strong demand recovery and it's not that surprising," said Andy Sommer, senior oil analyst with EGL Group.
He added that even in an environment of more robust fuel demand, it will still take a long time to clear swollen stocks of oil and oil products stored at land and on floating vessels.
"The overall inventories picture is still bearish," he said.
Ship brokers estimated product volumes, mostly heating oil, are above 90 million barrels and higher than the world's daily oil consumption. [
]Also on the supply front, oil companies were quickly restoring Gulf of Mexico production shut by Tropical Storm Ida, the U.S. Minerals Management Service said on Wednesday. [
]Analysts said that weakness in the dollar, near 15-month lows against a basket of currencies, waslikely to curb oil losses going forward. [
]Oil and the dollar tend to be inversely correlated because a weak dollar makes the commodity relatively cheap to non-dollar buyers.
The expectation that U.S. interest rates will remain near zero for the foreseeable future also increased the appeal of higher-yielding assets such as oil.
"The dollar will remain a very important factor as there is a natural link between the two markets," said Sommer.
