Oil rose to near 92 dollars a barrel last Wednesday, boosted by a fall in the dollar to two-month lows.

Brent crude extended gains on worries over a supply crunch.

The discount for U.S. crude futures benchmark West Texas Intermediate (WTI) against Brent remained strong at more than six dollars a barrel, but below the eight dollars level hit before the February Brent contract expired last Friday.

But gains in U.S.crude could be capped by the impending restart of Alaska’s main oil pipeline after a shutdown, as well as a suggestion by the International Energy Agency that OPEC may have raised output in response to high oil prices.

On the other hand, Brent prices have been buoyed by concerns over disruptions in North Sea crude supplies.

“We don’t expect any drastic price movements today — there’s a bit of holiday mood still in crude, with trading volumes still fairly low, and the market is in a consolidation mode,” said Matthew Lewis, an analyst at CMC Markets in Sydney.

“For WTI, at around 91 dollars, you will probably see some rebound.”

U.S. crude for February delivery rose 48 cents to 91.86 dollars a barrel, after settling down 16 cents at 91.38 dollars a barrel on Tuesday.

The February contract expires on Thursday.

London Brent rose 20 cents to 98 dollars a barrel, after gaining 37 cents to settle at 97.80 dollars a barrel.

Traders will scour U.S. economic data due later in the day for more clues to the state of demand in the world’s top energy consumer.

The Commerce Department will release December housing starts and permits, which are expected to be mildly positive.

Economists forecast a 550,000 annualised starts rate compared with a 555,000 rate in November.

A total of 560,000 permits is expected in December compared with 544,000 in the prior month.

The release of weekly U.S. industry and government oil inventory data this week will be delayed a day following Monday’s national holiday.

On the supply front, Alaska’s main oil pipeline should restore shipments to its normal rate of 630,000 barrels per day in under a week from around 510,000 bpd, after its recent shutdown due to a leak, the operator said on Tuesday.

The IEA said on Tuesday that OPEC leader Saudi Arabia had stealthily boosted output to cool an oil price rally.

Its assessment was starkly at odds with anecdotal evidence from Saudi Arabia’s big customers, and with the views of other analysts and consultants captured in a Reuters survey, which showed the kingdom’s output flat last month.
