US Cash Crude-Grades fall on second day of volatile roll trade period

Sept 24 (Reuters) - Physically traded domestic crude grades were down on Wednesday, dealers said, on the second 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 October to November traded at a midpoint of 50 cents a barrel.

U.S. oil refiners are expected to have about 1 million barrels per day of capacity offline in the week ending September 26, decreasing available refining capacity by 249,000 bpd, research company IIR Energy said.

U.S. crude and fuel inventories fell last week amid an uptick in demand, the Energy Information Administration said on Wednesday.
