LONDON, Feb 9 (Reuters) - Oil edged up on Wednesday, with North Sea Brent topping $100 again, due to market jitters over possible supply constraints stemming from unrest in Egypt and after data a day earlier showed a drop in U.S. stockpiles.
The upside, however, could be limited by China's rate hike on Tuesday and ahead of the release of U.S. government weekly oil data later on Wednesday, which may reveal record high crude stockpiles at the delivery point for U.S. crude, analysts said.
North Sea Brent crude futures <LCOc1> traded 71 cents higher at $100.63 compared with Tuesday's close of $99.92. U.S. crude <CLc1> rose 34 cents to $87.26 by 1046 GMT.
Brent crude traded at a record high premium of $13.39 a barrel to U.S. crude by the same time. <CL-LCO1=R>
"Brent is still reflecting the market concern about Egypt and the Suez Canal. Oil supply to Europe via the canal would have more impact than (any supplies to) the U.S.," Tony Nunan, assistant general manager with Mitsubishi Corp in Tokyo, said.
The massive protest in Egypt insisting President Hosni Mubarak step down immediately continued on Wednesday. The market was nervous about its impact on the operation of the Suez Canal.
The canal was operating normally on Tuesday despite strike action by 3,000 workers in companies owned by the Suez Canal authorities in Ismailia and Suez over pay and conditions. [

CUSHING INVENTORIES EYED
Olivier Jakob with Petromatrix said weekly data from the industry group American Petroleum Institute (API), which showed a surprise decline in U.S. crude inventories on Tuesday, was pushing oil prices higher for now.
But Jakob and analysts with Mizuho Corporate Bank said a rise in oil prices might be limited by swelling crude inventories and a long-term impact on oil demand after China's two rate hikes in a month.
"Caution about a slowdown in demand in China due to the rate hikes is strong (in the oil market). It is difficult to see development, where the oil market would keep on targeting higher prices aggressively," the bank said in its daily note.
The U.S. government's Energy Information Administration data due out at 1530 GMT will be closely watched. Analysts in a Reuters poll forecast the opposite to the API data.
The poll, which was taken before the industry and the government data releases, shows the EIA would report a 2.4 million barrel rise in U.S. crude stocks in the week to Feb. 4.
Crude stocks at the delivery point at Cushing, Oklahoma, may surge to a record high. [

SUPPORTS
Analysts pointed out glitches at some refineries in the United States, the world's top gasoline market, and the shutdown of the Poseidon oil pipeline in the U.S. Gulf of Mexico would lend the floor to the oil prices.
Poseidon handles about one eighth of Gulf oil output, market sources said on Tuesday. [
