NEW YORK, May 24 (Reuters) - U.S. crude oil futures edged up on Monday as buyers found prices near $70 a barrel attractive after their drop from above $87 in a span of three weeks.
News that Spain's central bank took over savings bank CajaSur [
] highlighted concerns that Europe's debt crisis may spread and curb economic recovery and demand growth, tempering oil's strength.U.S. crude <CLc1> rose 17 cents, or 0.24 percent, to settle at $70.21 a barrel, ranging from $69.57 to $70.96. In London, ICE Brent crude <LCOc1> fell 51 cents to settle at $71.17 a barrel.
"The market has dropped so sharply that it may be trying to find a bottom around $70. It shrugged off the dollar's strength," said Gene McGillian, analyst at Tradition Energy in Stamford, Connecticut.
Last Thursday's $64.24 front-month crude intraday low price was the weakest since prices fell to $62.76 on July 30, 2009.
Crude oil futures prices have slumped from an $87.13 intraday peak on May 3, the highest since prices reached $89.92 on Oct. 9, 2008.
"Oil futures are up but the market still has fears. Earlier, it was the news from Spain on the takeover of a small bank and now it's back to China as investors wonder if it will take steps that would pull down its economy," said Phil Flynn, analyst at PFGBest Research in Chicago.
The euro fell broadly, pulling back from gains last week, after the Spanish central bank's takeover of a savings bank added to jitters about debt problems in some of the weak euro zone countries. [

The Nasdaq gained after positive broker comments lifted technology shares, but the concerns about Europe's banking system restrained the Dow and the S&P 500 indexes. [
]BRENT PREMIUM TO WTI EASES
As traders wait to see if Europe's current financial troubles hit oil demand, Brent crude's premium to U.S. benchmark West Texas Intermediate narrowed from $1.64 on Friday to 96 cents on Monday, based on settlement prices.
That puts Brent's premium at its weakest level since April 14 when it stood at 29 cents.
"Brent's weakness may be because the two factors that had Brent higher were North Sea production down because of maintenance, and that's coming to an end, and the Cushing inventories which have been priced in," McGillian said.
Total U.S. crude inventories have been rising and stocks at the delivery hub for U.S. futures contracts in Cushing, Oklahoma, are at a record high.
Oil markets remain well supplied with the Organization of the Petroleum Exporting Countries pumping about 2 million barrels per day above output targets.
"The fundamentals of oil haven't suddenly changed. There's still plenty of oil about," said Rob Montefusco, a commodity broker at Sucden Financial.
While oil hovers near the low end of the $70-$80 range many in OPEC have said they prefer, OPEC officials have not yet called for any steps to prop up prices. The group is not scheduled to meet until October.
Shokri Ghanem, the chairman of Libya's National Oil Corp, said that OPEC was very worried about falling oil prices and was watching them closely. [
]Ahead of weekly reports on U.S. oil inventories, a Reuters survey of analysts on Monday yielded a forecast for crude stocks to have been little changed last week, estimated down only 100,000 barrels. [
]Distillate stocks were expected to be slightly higher and gasoline stocks unchanged.
Trading sources cited the heightened tensions between South Korea and North Korea [
] and Iran's ongoing dispute over its nuclear program [ ] as providing some support to oil on Monday. (Additional reporting by Gene Ramos in New York, Alex Lawler in London and Fayen Wong in Perth; Editing by Marguerita Choy and Jim Marshall)
