The price of oil fell back to around $98 a barrel Tuesday as analysts forecast another rise of U.S. crude stockpiles.
By early afternoon in Europe, benchmark U.S. crude for December delivery was down 74 cents at $97.94 a barrel on the New York Mercantile Exchange. It has fallen more than 4 percent so far in October.
U.S. crude supplies rose 21.5 million barrels in the four weeks ending Oct. 18, to levels nearly 10 percent above the five-year average.
Data for the week ending Oct. 25 is expected to show builds of 3.5 million barrels in crude oil stocks and of 1.5 million barrels in gasoline stocks, according to a survey of analysts by Platts, the energy information arm of McGraw-Hill Cos.
The American Petroleum Institute will release its report on oil stocks later Tuesday, while the report from the Energy Department's Energy Information Administration the market benchmark will be out on Wednesday.
