(Recasts with Iran-U.S. tensions, updates prices)
By Santosh Menon
LONDON, Jan 7 (Reuters) - Oil rose above $98 a barrel before falling back on Monday as reports of rising tensions in the Middle East outweighed concerns of demand outlook in top consumer United States from a feared economic recession.
CNN reported that five Iranian Revolutionary Guard boats harassed and provoked three U.S. Navy ships in the Strait of Hormuz on Saturday.
Citing unidentified U.S. officials, CNN said the Iranian vessels came within 200 yards (metres) of the U.S. ships and that after a threatening radio communication, U.S. sailors manned their ships' guns and were very close to opening fire.
Relations between the two countries are already tense over Iran's nuclear programme.
Traders said the news had helped put the focus back on geopolitical risks in the oil market.
"Crude rallied 60 cents on the news," Addison Armstrong, analyst at TFS Energy wrote in a report.
U.S. light crude for February delivery <CLc1> rose 14 cents to $98.05 a barrel by 1407 GMT, off lows of $97.11 hit earlier during the session. Oil had fallen by $1.27 on Friday.
London Brent crude <LCOc1> was 44 cents up at $97.23.
Oil has eased from a record peak of $100.09 a barrel last Thursday after a government report showed the U.S. unemployment rate up 5 percent in December, its highest in more than two years.
The bleak unemployment report was the latest signal that top energy consumer the United States could fall into a recession later this year.
U.S. ECONOMY
"Concerns about the U.S. economy are clearly putting some pressure on oil prices. Some market players are also using this opportunity to take profits," said Gerard Burg, a resource analyst from the National Bank of Australia.
Burg said that while OPEC rumblings over the weekend had not given any clear signal on what action the group might take at its next meeting, there were growing expectations that it would increase output to rein in prices.
Saudi Oil Minister Ali al-Naimi said on Sunday that the rise in oil prices had been determined by market forces, but declined further comment on what action the Organization of Petroleum Exporting Countries (OPEC) would take at its next meeting on Feb. 1 in Vienna. [
]Separately, OPEC president Chakib Khelil said on Saturday he expected oil prices to keep rising during the first quarter of this year before stabilising in the following quarter [
].Goldman Sachs, the most active investment bank in energy markets, also believes oil will stay strong and has kept its average 2008 price forecast unchanged at $95.
"We maintain that the combination of tighter short-term fundamentals and escalating costs will continue to provide strong support to oil prices in 2008, with the risk skewed to the upside from current levels," it said.
Crude speculators on the New York Mercantile Exchange boosted net long positions to a near two-month high in the week ended Dec. 24, the Commodity Futures Trading Commission said on Friday.
The increase in bullish sentiment came just before oil prices hit last week's peaks. (Additional reporting by Fayen Wong in Sydney, Randy Fabi in London and Robert Gibbons in New York; Editing by James Jukwey)
