LONDON, Nov 24 (Reuters) - Oil traded above $81 a barrel on Wednesday, rising from a near-week's low in the previous session on expectations of falling inventories in top consumer the United States.
Weekly U.S. government data due at 1530 GMT is expected to show a drop in crude oil inventories, although industry group the American Petroleum Institute reported on Tuesday that crude stocks rose. [
]By 1401 GMT, U.S. crude <CLc1>, also known as WTI, rose 43 cents to $81.68 a barrel. It fell to $80.28 intra-day on Tuesday, the lowest price since Nov. 17. Brent crude <LCOc1> was 50 cents up at $83.75.
More U.S. economic data depicted a mixed recovery scenario. Weekly unemployment benefit claims dropped, signalling an improving labour market; while consumer spending rose for the fourth consecutive month in October. [
]But new orders for U.S. manufactured goods fell unexepectedly, showing the largest decline in almost two years.
The dollar pared gains versus the euro after the data. Earlier in the session, the euro <EUR=> plumbed two-month lows of $1.3284 against the U.S. dollar on uncertainty over Ireland's debt plan. <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ For a graph comparing peripheral euro zone economies
http://r.reuters.com/zem66q ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^> Increasing investor risk-aversion has seen oil prices fall about 8 percent since reaching a 2010 high of $88.63 on Nov. 11.
"Prices are being influenced by Ireland and euro zone debt issues, concerns about whether China is going to overtighten as it tries to fight inflation and last but not least the situation between North and South Korea," Societe Generale's global head of oil research Mike Wittner said.
"Markets are jittery and there is the Thanksgiving weekend, so volumes will be light and prices could be volatile," he said. "You often get some short covering ahead of a long holiday weekend, particularly with something like the crisis in Korea."
OIL STOCKS
MF Global analyst Edward Meir predicted the dollar's rally could go further, weighing on oil and pushing it below $80.
"Further strengthening here could come back and knock energy prices with more authority next time around, possibly taking prices through technical support of $79.50," Meir wrote in a report.
Investors are awaiting data from the U.S. Energy Information Administration (EIA) due at 1530 GMT, which is expected to indicate higher oil demand.
Analysts in a Reuters poll expect crude stocks to drop by 2.1 million barrels, extending a fall in stockpiles into a third week. [
]However, the API reported on Tuesday an unexpected 5.2 million-barrel increase in crude stocks on rising imports in the week to Nov. 19 -- limiting the rebound in prices. [
]"The inventory data from the API yesterday, and possible negative surprise from the (EIA) today, is also responsible for the not-very-pronounced bounce off the lows," Commerzbank analyst Eugen Weinberg said.
The API said gasoline stocks fell 499,000 barrels and distillate stocks dropped 311,000 barrels, smaller declines than forecast in the poll.
