Oil fell

West Texas Intermediate crude fell to the lowest level in five weeks after a government report showed bigger-than-expected gains in gasoline and distillate supplies as demand slid.

Prices declined as much as 0.9 percent. Inventories of gasoline and distillate, including diesel fuel and heating oil, each climbed more than twice as much as forecast in the week ended Jan. 3. Total products supplied, a measure of demand, tumbled 4.1 percent to the lowest level in seven months, according to a report today from the Energy Information Administration.

Crude prices also fell as Libya’s state-owned National Oil Corp. said production increased because of the resumption of pumping from the Sharara oil field. Output rose to 546,000 barrels a day yesterday.

WTI for February delivery dropped 75 cents, or 0.8 percent, to $92.92 a barrel at 10:47 a.m. on the New York Mercantile Exchange. The volume of all futures traded was 6.5 percent above the 100-day average.

Brent for February settlement slid 13 cents to $107.22 a barrel on the London-based ICE Futures Europe exchange. Volume was 4.4 percent above the 100-day average. The European benchmark crude was at a $14.30 premium to WTI. The spread closed at $13.68 yesterday.
