US Cash Crude-Grades mixed on final full day of volatile roll trade period

HOUSTON, Nov 25 (Reuters) - U.S. crudes were mixed on Tuesday, dealers said, on the third and final full day of the volatile roll trading period.

Traders use the three-day roll period to adjust their crude slates, square up positions and net out exposures following the expiration of the U.S. crude futures contract.

Prices to roll U.S. crude oil futures positions from December to January traded at a midpoint of 15 cents a barrel.

U.S. crude stocks fell while fuel inventories rose last week, market sources said, citing American Petroleum Institute figures on Tuesday.

Crude stocks fell by 1.86 million barrels in the week ended November 21, the sources said on condition of anonymity.

Gasoline inventories rose by 539,000 barrels, while distillate inventories rose by 753,000 barrels from a week earlier, the sources said. API/S

Meanwhile losses were curbed for some grades as the spread between West Texas Intermediate crude futures and global benchmark Brent widened, which typically makes U.S. grades more attractive to foreign buyers.
