* Strong equities performance lift crude prices

SINGAPORE, Feb 9 (Reuters) - London crude prices rallied more than half a percent Wednesday, back up above $100 a barrel due to tighter North Sea supplies and concerns over a strike at firms owned by the Suez canal authority, although transit through the waterway was unaffected.
ICE Brent rose 60 cents to $100.52 a barrel at 0710 GMT, with U.S. crude for March up 66 cents to $87.60 a barrel. The spread between the two benchmarks widened to $12.92 a barrel. <CL-LCO1=R>
"Constraints in North Sea supplies will continue to cause the spread between the two benchmarks to be quite wide," said Ben Westmore, analyst at National Australia Bank based in Melbourne.
North Sea Forties crude oil supplies are slightly tighter for March. So far, around 793,000 barrels per day (bpd) are seen for March loading, down from around 850,000 bpd scheduled for February.
"The unrest in Egypt also seems to have more of an impact on Brent prices rather than WTI, but there isn't a lot of upside to oil prices in general," added Westmore, a sentiment that is shared by other analysts.
Egyptians staged one of their biggest protests yet on Tuesday demanding President Hosni Mubarak step down now, their wrath undiminished by the vice president's announcement of a plan to transfer power.
Adding to the turmoil was a strike staged by about 3,000 workers in companies owned by the Suez Canal authorities in Ismailia and Suez over pay and conditions.
Investors shrugged off risks posed by a rise in Chinese interest rates over week-long holidays with the market braced for further rate rises as the world's second biggest energy consumer struggled to contain inflation.
"Chinese policymakers' efforts to rein in overheating pressures are now seen in a relatively more positive light by global investors in that they will help slow growth to a more sustainable pace, while other engines of growth in the region begin to rev up," said Samarjit Shankar, analyst at BNY Mellon.
BULLISH U.S DATA MAY NOT BE ENOUGH
Supporting prices, U.S. crude stocks unexpectedly fell 558,000 barrels last week on sharply lower imports, the American Petroleum Institute (API) said on Tuesday. This contrasted expectations from analysts polled by Reuters who had expected a 2.4 million-barrel rise in crude stocks.
Crude imports fell 1.1 million barrels a day (bpd) to 8.65 million bpd, while crude stocks at Cushing, Oklahoma, the delivery point for U.S. oil futures, fell by 927,000 barrels, API said.
The U.S. Energy Information Administration (EIA) said more supply will be needed as the world will consume about 140,000 bpd more in oil than it had forecast last month, with demand now expected to average a record 88.16 million barrels per day this year.
Bullish sentiment in equities also underpinned crude. The Dow Jones industrial average notched a seventh straight day of gains on Tuesday, rising 0.6 percent, as surprisingly strong sales by McDonald's boosted optimism about consumer spending.
Japan's Nikkei hit a 9-month high before retreating to close down 0.2 percent as bank shares were hit by profit-taking, but Australia's benchmark index rose 0.3 percent and New Zealand shares also gained.
"The (U.S.) crude oil market is now held up by the bullish stock market, rather than geopolitical reasons," said Benson Wang of Commodity Broking Services in Sydney.
"The Egyptian unrest had pushed the market up in the last 15 days, but I think people's reaction towards that is now calmer, and the effects on (U.S.) oil prices are reducing." (Editing by Himani Sarkar)
