LONDON, March 18 (Reuters) - European shares slipped back from the previous session's 17-month closing highs in early trade on Thursday, with banks and commodity stocks taking the most points off a key index.
At 0911 GMT, the FTSEurofirst 300 <
> index of top European shares was down 0.2 percent at 1,068.75 points, after rising 0.9 percent in the previous session to its highest close since early October 2008.The European benchmark is up more than 65 percent from its lifetime low of March 9, 2009.
Banks fell, having gained sharply in the previous session, following the U.S. Federal Reserve's pledge to keep interest rates near zero for an extended period.
Barclays <BARC.L>, BNP Paribas <BNPP.PA>, Banco Santander <SAN.MC>, HSBC <HSBA.L> and UBS <UBSN.VX> fell between 0.6 and 1.5 percent.
"It will be difficult for the market to push higher from here," said Bernard McAlinden, investment strategist at NCB Stockbrokers in Dublin.
"The market is pricing in that there is no prospect of higher interest rates any time soon in the west, but that's because of a danger of a relapse in the economy, and there are doubts creeping in about the German support for the Greece rescue plan."
Greece may seek financial aid from the International Monetary Fund next month because it is growing increasingly pessimistic about the prospect of help from the European Union, Dow Jones Newswires reported on Thursday. [
]Prime Minister George Papandreou said on Thursday Greece will not be able to carry out planned deficit cuts to resolve its debt problems if it has to continue borrowing money at high interest rates. [
]But he made no mention of turning to the European Union or the International Monetary Fund for help, saying, however, that Greece was implementing IMF style structural reforms without having access to IMF funds. He said he hoped Greece would not have to go to the international lender for help.
Commodity stocks also gave back some of the previous sessions' gains, as the dollar strengthened, hurting oil and metals prices.
Oil companies falling included Total <TOTF.PA>, ENI <ENI.MI>, BP <BP.L> and Royal Dutch Shell <RDSa.L>, down between 0.3 and 1.3 percent.
Among the miners, Antofagasta <ANTO.L>, Eurasian Natural Resources Corp. <ENRC.L>, Fresnillo <FRES.L> and Rio Tinto <RIO.L> fell between 0.5 and 0.9 percent.
Across Europe, Britain's FTSE 100 <
>, Germany's DAX < > and France's CAC40 < > were down between 0.2 and 0.4 percent.
GLAXOSMITHKLINE RISES
GlaxoSmithKline <GSK.L> gained 2.3 percent after Novartis <NOVN.VX> handed back U.S. rights to a drug widely thought to be a generic copy of Glaxo's blockbuster Advair, reducing the threat of cheap copies of the lung drug in the company's biggest market. [
]Shire <SHP.L>, AstraZeneca <AZN.L>, Merck <MRCG.DE> and Roche <ROG.VX> were up between 0.4 and 0.8 percent.
Novartis was little changed.
