Jan 22 (Reuters) - Grades broadly rose on Wednesday, the first full day of the roll trade that traders use to manage their positions, dealers said.

Traders use the three-day roll period following the expiry of the WTI contract to square positions and manage exposure, resulting in more volatile trading.

Prices to roll U.S. crude oil positions from February to March traded at 40 cents a barrel, dealers said.

U.S. crude oil and fuel stocks rose last week, market sources said, citing American Petroleum Institute figures.

Crude stocks rose by 958,000 barrels in the week ended Jan. 17, the sources said on condition of anonymity. Gasoline inventories rose by 3.23 million barrels, and distillate stocks climbed by 1.88 million barrels, they said.

Investors awaited official U.S. oil stocks data from the Energy Information Administration on Thursday at 12:00 p.m. EST (1700 GMT).

In refining news, LyondellBasell Industries LYB.N will begin the permanent closure of its 263,776 barrels per day (bpd) Houston refinery this coming weekend, said people familiar with plant operations.

U.S. oil refiners are expected to have about 1.16 million bpd of capacity offline in the week ending Jan. 24, decreasing available refining capacity by 91,000 bpd, research company IIR Energy said on Wednesday.

Offline capacity is expected to rise to 1.27 million bpd in the week ending Jan. 31, IIR added.
