West Texas Intermediate crude dropped to the lowest level in more than a week as falling demand boosted fuel inventories amid concern that the Federal Reserve will curb stimulus.

Prices slid as much as 1.1 percent. Stockpiles of gasoline and distillate fuels, including diesel and heating oil, jumped the most last week since Jan. 4, the Energy Information Administration reported on Dec. 11. The Fed will start slowing its monthly bond purchases at its Dec. 17-18 meeting, according to 34 percent of economists surveyed Dec. 6 by Bloomberg, an increase from 17 percent in on Nov. 8.

“Demand is weak and if we don’t see it become stronger, the market will come under pressure,” said Gene McGillian, an analyst and broker at Tradition Energy in Stamford, Connecticut. “Products are being put into storage, basically driving the market lower. The market is concerned about Fed tapering.”

WTI for January delivery declined 84 cents, or 0.9 percent, to $96.66 a barrel at 10:07 a.m. on the New York Mercantile Exchange.
