Economic gloom deepened after the U.K.'s Royal Bank of Scotland posted the biggest loss in the country's corporate history, with stock markets in Asia following European counterparts lower.

The dollar rose to a six-week high against the euro on the news, making U.S.-denominated commodities less attractive to investors.

The U.S. was closed on Monday for the Martin Luther King holiday, and trade was thin, especially on the front month February contract, due to expire on Tuesday.

U.S. light crude for February delivery fell to $34.70 by 0149 GMT, around the same level as late on Monday, when no official settlement was issued due to the holiday.

March Nymex, which takes over as front month on Wednesday, was down $1.61 at $40.96 by 0217 GMT, and more than $6 a barrel above the February contract due to brimming crude stocks at Cushing, Oklahoma, the delivery point for NYMEX contracts.

London Brent crude rose 10 cents to $44.60 a barrel, having settled down $2.07 on Monday.

"Seasonal cold weather continues to be the only supportive factor on the demand side," said French bank Societe Generale in an overnight report.

Oil prices have fallen by more than three quarters since record highs above $147 a barrel hit last July, as a financial crisis has evolved into a global economic crisis and weakened oil demand.

Two recent supportive factors have been removed, after Russia and Ukraine signed a 10-year gas deal clearing the way for the resumption of supplies to a freezing Europe, and implementation of a ceasefire between Israel and Hamas in Gaza also eased supply worries.

China, once a driver of the surge in oil prices, is expected to release this week fourth quarter GDP data that economists say will show a 7.0 percent rise, much higher than in the developed world, but the slowest pace of expansion for the country in nearly a decade.
