BERLIN (AFP) - Germany extended a guarantee to all private savings accounts Sunday as Chancellor Angela Merkel said her government was scrambling to salvage a rescue plan for the country's fourth biggest bank. Finance ministry spokesman Torsten Albig told AFP that the unlimited guarantee would cover all Germans' personal deposits as Berlin moved to shore up confidence amid a spreading financial crisis. Merkel told reporters earlier the government was "pulling out all the stops" to save stricken Hypo Real Estate (HRE) after a banking consortium withdrew from a 48-billion-dollar rescue plan late Saturday. "The government says today that we will not allow an institution's crisis to become a crisis for the entire system," the conservative leader said. But hitting back at accusations that the government is preparing to bail out fat cats at average citizens' expense, Merkel warned that those who did irresponsible business would be held accountable. "We owe that to the taxpayers in Germany," she said. Her remarks came after the leaders of France, Germany, Britain and Italy gathered in Paris Saturday to pledge a more coordinated approach to prevent the meltdown in US financial markets from engulfing their own economies. While the four powers put on a united front, there was no talk of a joint bail-out fund for European banks on the model of the 700 billion dollar US package, after the idea was shot down by London and Berlin. The rescue bid for HRE was the largest in German history and came after the bank was sucked into the global financial turmoil by its inability to refinance debt, one of many high-profile European emergency cases in the past two weeks. The deal was stitched together in haste at the end of September and its failure Saturday sent officials racing back to the drawing board. Finance Minister Peer Steinbrueck said HRE had an "unforeseen liquidity gap in the billions" of euros range but also assured that the left-right government was determined to find a solution. The Social Democrat said he was "quite appalled" that the bank's management had not revealed the extent of its liquidity crisis earlier. But he said Berlin would nevertheless do what it could to avert its collapse "because the damage not only for the Federal Republic of Germany but also for many European financial services providers who are interlinked with us would be incalculably large." Dropping its bombshell Saturday, HRE said in a statement that a consortium of German banks taking part in the rescue had "refused to provide liquidity lines." The online service of Der Speigel news weekly reported that HRE would need 50 billion euros in liquidity by the end of this year with an additional 10 billion euros required in 2009. Merkel and Steinbrueck made their joint statement as officials from the finance ministry, the financial market supervisory board and the Bundesbank huddled for crisis talks, sources said. Senior staff from the three institutions aimed to determine the extent of HRE's needs and plot a way forward before markets reopen Monday. Steinbrueck and representatives from private banks were expected to join the meeting later Sunday, the sources said. In his remarks, the finance minister assured that German bank account holders needed not worry about losing a "single euro" in the crisis. "That is an important message intended to create calm and not reactions that would be disproportional and make the current crisis management and crisis prevention even more difficult," he said. Despite the assurances, one German minister could not resist an alarmist take on the gathering storm in Europe's biggest economy. Interior Minister Wolfgang Schaeuble warned in a magazine interview that the global financial crisis could have political repercussions, noting that Adolf Hitler rose to power following the 1929 Wall Street crash. "We learned from the worldwide economic crisis of the 1920s (and 1930s) that an economic crisis can result in an incredible threat for all of society," he was quoted as saying in an advance copy of Der Spiegel's Monday edition. "The consequences of that depression was Adolf Hitler and, indirectly, World War II and Auschwitz."
