Oil edges up; strong dollar, OPEC doubts make buyers cautious
By Devika Krishna Kumar
NEW YORK (Reuters) - Oil rose slightly on Friday on futures buying, ending the week higher, but gains were limited by a strong U.S. dollar and lingering doubts about whether OPEC producers would stick to a deal to cut output.
Market players attributed choppy trading to position-squaring at the end of the week and low volumes at the start of the year.
Brent crude futures LCOc1 settled 21 cents higher at $57.10 per barrel, after trading in a range of $56.28 to $57.47. The contract posted gains for the second week in a row.
U.S. West Texas Intermediate (WTI) crude futures CLc1 ended the session up 23 cents at $53.99 a barrel, after swinging between $53.32 and $54.32. WTI notched its third straight weekly gain.
"There's a lot of volatility, or at least changes in direction," ABN Amro senior energy economist Hans van Cleef said. "People think the long-term trend is up, but after a gain of a few dollars, they take profit."
The dollar .DXY gained broadly after the U.S. non-farm payrolls report showed slower hiring in December but an increase in wages, feeding expectations of further interest rate increases from the Federal Reserve this year.
