NEW YORK, Jan 21 (Reuters) - ICE Brent crude futures rose on Friday on lift from rising German and French business sentiment which boosted the euro to a two-month peak against the dollar while U.S. oil stalled near $89 in choppy trading.
German business morale jumped to its highest level in 20 years in January, surging past economists' forecasts, according to the Munich-based Ifo economic institute. while French data showed business confidence also rose. [
]The euro rose to a two-month high versus the dollar, helped by Asian demand and the improved confidence in the euro zone. [
]U.S. oil prices slipped as the rising oil stockpiles reported during the previous session curbed an earlier advance on the dollar's weakness.
In London, ICE Brent crude for March <LCOc1> rose 57 cents, or 0.59 percent to $97.15 a barrel at 12:05 p.m. EST (1705 GMT).
U.S. crude oil for March delivery <CLc1> fell 49 cents to $89.10 a barrel.
Both the Brent and U.S. crude contracts were on track to post weekly losses. The Brent contract pushed above $99 a barrel last Friday, as the Brent February crude contract expired.
U.S. crude prices had a sharp price retreat on Thursday, triggered by the inventory builds and concerns China may take more measures to cool stubborn inflation, resulting in slower growth in demand for oil and other commodities.
U.S. crude oil inventories rose 2.62 million barrels last week, against a forecast that stockpiles would be lower, and refined products stocks increased more than expected, the U.S. Energy Information Administration said on Thursday. [
]But the dollar's weakness and the business sentiment data in the euro zone were able to limit U.S. oil's losses and did lift prices earlier on Friday.
"A combined move with the weaker dollar and improving business confidence in Germany is supporting oil. On Thursday we saw a very strong support point... We could see a test of the upper level, which is $99.20 for Brent," said Thorbjorn Bak Jensen, an analyst at A/S Global Risk Management Ltd.
Despite the shifts to new front-month contract's this week, Brent futures have stayed at an unusually strong premium to U.S. crude.
Brent's premium to U.S. benchmark West Texas Intermediate crude <CL-LCO1=R> topped $8 a barrel intraday on Friday, just below last week's $8.24, which was the widest since February 2009.
"The spread is starting to get rather stretched and when it does get rather stretched there is usually a sharp correction at some point," said Michael Hewson, a market analyst at CMC markets. (Additional reporting by Gene Ramos in New York and Jessica Donati in London;editing by Sofina Mirza-Reid)
