HOUSTON (Reuters) - Oil prices settled lower on Monday, pressured by a strengthening dollar and rising U.S. crude output, but prices remained on track for the biggest January increase in five years.
Brent crude futures LCOc1 for March delivery settled down $1.06, or 1.5 percent, at $69.46 a barrel, after rallying to a session high of $70.64.
U.S. West Texas Intermediate (WTI) crude futures CLc1 fell 58 cents, or 0.9 percent, to close at $65.56 a barrel.
The rally in oil prices has been buoyed by the U.S. dollar's six straight weekly slides. The greenback is set to fall 3 percent this month. .DXY Oil is priced in the U.S. currency, so a falling dollar can boost demand for crude from buyers using other currencies.
The dollar index had been below $90 since Jan. 24. But the currency has rebounded 0.3 percent since Friday to $89.31, which has weighed on crude prices.
“The strength in the dollar pushed some sellers in the market. There are some warning signs that maybe the rally is getting a bit overextended,” said Gene McGillian, manager of market research at Tradition Energy in Stamford, Connecticut.
Analysts expected U.S. crude supplies would post a weekly rise for the first time in 10 weeks, a preliminary Reuters poll showed on Monday. Industry group American Petroleum Institute posts its data on Tuesday and the U.S. Energy Information Administration reports on Wednesday.
Crude prices also had drawn support from a large premium in the front-month Brent oil contract over those for future delivery, as investment in crude futures and options reached a record high last week. [O/ICE]
Oil consumption is surging as a result of growth in major economies, while OPEC and its allies have made repeated commitments to limiting their crude output.
On Monday, Iraq’s oil minister said in London that the oil market was improving, and that the country would comply with OPEC output cuts even though it is trying to increase its oil export capacity.
Somewhat offsetting the OPEC-led cuts has been rising oil output in North America.
U.S. output C-OUT-T-EIA has jumped more than 17 percent since mid-2016. It is expected to exceed 10 million bpd soon.
U.S. energy firms added 12 oil rigs for new production in the week to Jan. 26, Baker Hughes reported on Friday,, which added to bearish sentiment in the market.
“Today’s lower oil prices were a partial correction and a reaction to increasing drilling activity,” said James Williams, an energy economist at WTRG Economics in London, Arkansas.
