LONDON, May 19 (Reuters) - European stocks hit their lowest closing level in nearly two weeks on Wednesday, dragged down by banking shares, as investors became jittery following Germany's move to ban naked short sales of a range of financial assets.
Appetite for risky assets fell, with the VDAX-NEW volatility index <.V1XI> surging 21 percent. The higher the index, which is based on sell and buy options on Frankfurt's top-30 stocks <0#.GDAXI>, the lower the market's desire to take risk.
The FTSEurofirst 300 <
> index of top European shares ended 3 percent lower at 996.38 points. It fell below 1,000 for the first time since a 750 billion euro ($930 billion) package aimed at preventing the Greek debt crisis from spreading was unveiled earlier this month.Financial stocks were among the top losers, with the STOXX Europe 600 banking index <.SX7P> falling 3.5 percent. Barclays <BARC.L>, Lloyds <LLOY.L>, Royal Bank of Scotland <RBS.L>, BNP Paribas <BNPP.PA>, Societe Generale <SOGN.PA>, Credit Agricole <CAGR.PA> and Natixis <CNAT.PA> fell 3.2 percent to 5.5 percent.
"The markets never like governments interfering in what they regard as the efficient running of markets. A ban on short selling tends to have the adverse effects of sending traders looking for other methods of shorting the market," said Bill McNamara, analyst at Charles Stanley in Sweden.
"It just doesn't settle the nerves in the way politicians seem to think it will. Investors should continue to expect high levels of volatility."
In a surprise move late on Tuesday, Germany banned against bets on bonds, stocks and credit protection in a tentative crack down on speculative trading, which has been widely blamed by leaders for exacerbating the euro zone debt crisis.
German financial watchdog BaFin said the ban had been imposed "due to the extraordinary volatility in government bonds in the euro zone" and warned that massive short selling could have endangered the stability of the financial system.
German Chancellor Angela Merkel's speech to parliament that the euro was in danger also hurt sentiment. She urged speedy action to stop market "extortion," and said the EU needed a process for "orderly" insolvency of its members. [
]"There is nervousness around the potential for a difficult second half of the year, which could well be exacerbated by the significant increase in regulatory risk for financial services," said Henk Potts, strategist at Barclays Wealth.
Southern European indexes fell, with Spain's IBEX <
