European Union nations outside the eurozone pressed the single currency area on Tuesday to move fast with a convincing firewall to stop debt contagion endangering the entire 27-nation bloc. Britain and Sweden, fresh from overnight talks held in parallel to a closed-door meeting of eurozone finance ministers, led a charge on behalf of 10 non-euro states worried about being dragged down by the crisis. "Europe is running dry on credibility," said Sweden's Finance Minister Anders Borg, who said the "solution to the debt crisis must be lower debt." Worries for the future of the 17-nation eurozone increased on Tuesday as Italy's borrowing costs hit another record. Investors meanwhile are concerned a bailout fund behind Greek and other rescues might simply be too small to rescue Italy, the eurozone's third-biggest economy. On heading into a meeting of all 27 EU finance ministers, British Chancellor George Osborne urged eurozone nations to act to beef up their rescue pot "to show the world it can stand behind its currency." Osborne said "we need to focus on getting the firewall in place," in reference to plans to increase the firepower of the European Financial Stability Facility (EFSF) from 440 billion euros to one trillion euros. "It is all very well saying we've got the firewall but we need to convincingly show the world that the firewall exists and it has sufficient resources in it," he added. "The eurozone needs to show the world it can stand behind its currency, it cannot just wait on developments in Athens and in Rome." The eye of the debt storm has shifted from Athens to Rome, with fears over Italy's 1.9-trillion-euro debt pile pushing embattled Prime Minister Silvio Berlusconi to open up the country's books to international scrutiny. "The movement in Italian yields is worrisome as it's similar to what happened to Greece, Ireland and Portugal," said ING investment analysts. They added that clarification was needed on how the EFSF is to be leveraged up to one trillion euros -- which many market experts already say is still too small. "Italy knows, that given the size of the country, it can't hope to get help from outside," Austria's Finance Minister Maria Fekter, whose country is part of the eurozone, added going into Tuesday's talks. The 10 EU states that have stuck to national currencies have demanded to have a bigger say in the decision-making of the eurozone, fearing they will be left out of major policies that could affect the 27-nation bloc's single market. The 10 non-euro EU states are: Britain, Bulgaria, Czech Republic, Denmark, Hungary, Latvia, Lithuania, Poland, Romania and Sweden.
