Oil jumps 8 pct as Saudi cuts supplies

NEW YORK (Reuters) - Oil prices jumped 8 percent on Wednesday on signs that OPEC kingpin Saudi Arabia has slashed supplies to customers for January as the economic crisis continues to slow demand.

Saudi Arabia told major customers it was reducing supplies substantially next month in a move that could bring the kingdom's output below its implied OPEC target of 8.47 million barrels per day.

"There are quite severe cuts -- they are going to be seriously cutting back," a trader with one major customer said.

U.S. crude jumped $3.22 to $45.29 a barrel by 12:44 p.m. EST (1744 GMT) after touching a session high of $46.17. London Brent crude traded up $2.72 to $44.25 a barrel.

OPEC next meets on Dec. 17, and the group is widely expected to agree to more output cuts. Slumping demand in the United States and other developed economies has knocked crude down sharply from record highs over $147 struck in July.

A U.S. Energy Information Administration report this week forecasting the first contraction in world oil demand since 1983 added to expectations that OPEC will deepen cuts.

"This news about the Saudis getting ready to make its cut confirms what appears to be a foregone conclusion that indeed, the group will cut some more," Phil Flynn, analyst at Alaron Trading in Chicago, said.

Earlier, crude came under pressure as U.S. inventory data showed rising fuel stocks in the world's top consumer as demand slumps.

Distillate stocks rose by 5.6 million barrels in the week to Dec. 5, according to Energy Information Administration, while gasoline stocks gained 3.8 million barrels. Crude inventories rose slightly.
