LONDON, Jan 27 (Reuters) - European shares fell on Wednesday, with banks the main drag following badly-received quarterly results from Spanish lender BBVA <BBVA.MC> and investor concerns over Greece's fiscal problems.
The FTSEurofirst 300 <
> index of leading European shares closed down 0.9 percent at 1,013.83 points. The index is down around 3 percent so far this month and is on track to post its worst monthly performance since the recovery started in March.Banks featured among the worst performers. BBVA fell 6.4 percent after it said its bad loans ratio rose nearly one percentage point in the fourth quarter from the third. [
]Banco Santander <SAN.MC>, HSBC <HSBA.L> and Barclays <BARC.L> lost 1.6 to 5.1 percent, while Greece's Alpha Bank <ACBr.AT>, Bank of Piraeus <BOPr.AT> and National Bank of Greece <NBGr.AT> fell 5.6 to 7.9 percent.
"We cannot hold the gains which is not a good sign ... Greece is a great problem," said Giuseppe-Guido Amato, strategist at Lang & Schwarz in Frankfurt.
"If the uncertainty related to Greece is increasing then you see the dollar firm against the bunds. The strengthening of the dollar is correlated with falling markets."
The dollar rose to a six-month high against the euro on concerns over Greece's fiscal problems, while the spread of the 10-year Greek bond yield over benchmark German Bunds rose to its highest since Greece adopted the euro currency in 2001. [
]Investor sentiment was knocked after Greece denied press reports to sell up to 25 billion euros ($35 billion) of bonds to China. [

COMMODITIES UNDER PRESSURE
Energy stocks were under pressure after crude <CLc1> edged below $75 a barrel as the dollar rose. BG Group <BG.L>, BP <BP.L>, Royal Dutch Shell <RDSa.L> and Total <TOTF.PA> fell 1.1 to 2.4 percent.
Mining stocks were lower as metal prices retreated, with copper <MCU3=LX> down 2.1 percent. Anglo American <AAL.L>, Antofagasta <ANTO.L>, BHP Billiton <BLT.L> and Xstrata <XTA.L> slipped 0.4 to 3.2 percent.
"A big part of the recovery has already been priced in, so equities don't react to good news anymore, but react to any piece of negative news," said Pierre Sabatier, president and head of strategy at PrimeView in Paris.
"Even if monetary policy remains extremely favourable and corporate results are improving, the market was ripe for a correction. Historically, very few market rebounds, as strong as this one, didn't experience a correction of at least 10 percent at some point."
In economic news, sales of newly built U.S. single-family homes fell unexpectedly in December, data showed, the latest indication that the government-led housing recovery might be losing some steam. [
