LONDON, Feb 17 (Reuters) - European shares fell to their lowest close in three weeks on Tuesday, with banks down on worries of further losses and the impact of a recession in emerging Europe and energy stocks tracking lower oil prices.
The FTSEurofirst 300 <
> index of top European shares fell 2.5 percent to 765.43 points, its lowest close since Jan. 23. It has lost 8 percent this year, following a 45 percent decline in 2008.Ratings agency Moody's said the recession in emerging European economies would be more severe than elsewhere due to large imbalances and would put the financial strength ratings of local banks and western parents under pressure.
Rival ratings agency Standard & Poor's (S&P) echoed this view, saying difficulties faced by Western banks in supplying their subsidiaries in emerging Europe with funding could prompt an overall ratings review for the region's banks. [
]Banks took most points off the index. Societe Generale <SOGN.PA> fell 9.6 percent to its lowest close in more than 10 years, ahead of results on Wednesday. HSBC <HSBA.L> fell 6.8 percent after Morgan Stanley said it was staying underweight on the stock and becoming more bearish on the outlook for profit in 2009 and 2010.
"There's a lack of good news out there," said Howard Wheeldon, strategist at BGC Partners, in London. "There are a lot of things going on, but no quantifiable certainty that anything such as the Obama package will make a real difference soon enough." "There's nothing for a bull to hang his hat on."

"The news on emerging Europe is important, especially for countries like Austria and Germany and for certain banks. The focus today is on the banks but it is also valid for the manufacturing sector," said Gerhard Schwarz, head of global equity strategy at UniCredit in Munich.
INSURERS SLIDE
Insurers were also among the biggest casualties on worries about more writedowns, as more companies default on loans. Shares in Aegon <AEGN.AS> fell 11.4 percent, after the Dutch company reported a bigger than expected preliminary loss of 1.2 billion euros in the fourth quarter.

Royal Dutch Shell <RDSa.AS>, Repsol <REP.MC>, and Total <TOTF.PA> shed 1.6-3.5 percent.
Shares in Daimler <DAIGn.DE>, which makes Mercedes-Benz cars, closed 3.8 percent lower after it declined to give a profit forecast for this year when delivering a fourth-quarter loss, weighed by significant losses and charges at Chrysler.
Fiat <FIA.MI> shares initially fell sharply after a Bloomberg report the company was considering a rights issue but recovered to 0.5 percent down after the company dimissed the story as groundless.
