US Cash Crude-Grades slip after EIA data show rise in domestic oil stocks

Sept 10 (Reuters) - Grades broadly slipped on Wednesday, dealers said, after domestic oil stocks rose according to government data.

U.S. crude and fuel inventories rose last week as exports and demand declined, the Energy Information Administration said on Wednesday.

Crude stockpiles rose by 3.9 million barrels to 424.6 million barrels in the week ended September 5, the EIA said, compared with analysts' expectations in a Reuters poll for a draw of 1 million barrels.

On the demand side, U.S. oil refiners are expected to have about 585,000 barrels per day (bpd) of capacity offline in the week ending September 12, decreasing available refining capacity by 154,000 bpd, research company IIR Energy said.

Offline capacity is expected to increase to 702,000 bpd in the week ending September 19, IIR added.
