LONDON, May 3 (Reuters) - European shares fell in thin trade on Monday, with banks slipping on concerns a massive bailout package for Greece may face political problems and on doubts about whether Greece can sustain the tough austerity measures.
China's move on Sunday to raise the proportion of deposits that lenders must keep in reserve at the central bank, and prospects of tougher banking regulations in the United States also hurt market sentiment, analysts said.
Financial stocks were among the top losers, with STOXX Europe 600 banking index <.SX7P> falling 0.3 percent. UBS <UBSN.VX>, Banco Santander <SAN.MC>, BBVA <BBVA.MC> and Popular <POP.MC> fell 0.5 to 1.7 percent.
At 0812 GMT, the FTSEurofirst 300 <
> index of top European shares was down 0.3 percent at 1,059.11 points after falling 0.7 percent in the previous session. It dropped 2.7 percent last week, recording its third straight week of declines, hammered by mounting fears over sovereign debt in the euro zone."The fate of Greece is in the hands of the people of Greece. They have to agree as well," said Koen De Leus, economist at KBC Securities, in Brussels.
"We have had a great rally for more than a year and it's normal that there is going to be some push back. Investors are looking for excuses to take profits."
European finance ministers triggered a record 110 billion euro ($146.5 billion) bailout for Greece on Sunday after Athens committed itself to years of painful austerity. [
]The emergency aid, the most ever for a country, alleviated some fears of a near-term sovereign debt default, but the package still has to obtain parliamentary approvals and left open the question of which fiscally vulnerable country in Europe might be next. [

GREECE CONCERNS
Markets are deeply sceptical that Athens will be able to deliver on its latest promises for additional spending cuts and tax increases to reduce its budget gap to 3 percent of its economy by 2014, from more than 13 percent.
The European Central Bank said on Monday it suspended its minimum credit rating threshold on Greek sovereign debt, allowing the country to carry on participating in ECB lending operations even if rating agencies downgrade it further. [
]Commodity shares were also under pressure, with crude oil prices <CLc1> falling, to trade below $86 a barrel on concerns about euro zone's fiscal woes and fresh steps by China to cool its economy.
Among mining companies, Eramet <ERMT.PA>, Boliden <BOL.ST> and Aurubis <NAFG.DE> fell 0.6 to 2.4 percent. Oil company ENI <ENI.MI>, Repsol <REP.MC> and Total <TOTF.PA> shed 0.8 to 1 percent.
BP <BP.L> shares in Frankfurt <BP.F> fell 7 percent after the huge oil slick caused by an underwater leak continued to creep toward the U.S. Gulf Coast on Monday, with the Obama administration pressing the energy major to stem the oil gushing from its ruptured offshore well.
