Spain on Saturday proposed the set up of a new fiscal authority in the euro zone which would control and harmonize national budgets and manage the European debts.

Prime Minister Mariano Rajoy said the authority was the answer to the European debt crisis and would go a long way in alleviating Spain's woes as it would send a clear signal to investors that the single currency is an irreversible project.

Overspending in the regions and troubles with a banking sector badly hit by a property crash four years ago have sent Spain's borrowing costs to record highs and pushed the country closer to seeking an international bailout.

The risk premium investors demand to hold Spanish 10-year debt rather than German bonds rose to its highest since the launch of the euro - 548 basis points - on Friday.

The Spanish authorities, which have hiked taxes, slashed spending, cut social benefits and bailed out troubled banks, argue that there is little else they can do and the European Union should now act to ease the country's liquidity concerns.
In private, senior Spanish officials have said this could be done by using European money to recapitalize directly ailing banks or through a direct intervention of the European Central Bank on the bond market.
They have also said the euro zone should quickly move towards a fiscal union to complete its 13-year monetary union but Rajoy went a step further by making a formal offer.

"The European Union needs to reinforce its architecture," Rajoy said at an event in Sitges, in the north-eastern province of Catalonia. "This entails moving towards more integration, transferring more sovereignty, especially in the fiscal field.

"And this means a compromise to create a new European fiscal authority which would guide the fiscal policy in the euro zone, harmonize the fiscal policy of member states and enable a centralized control of (public) finances," he added.
He also said the authority would be in charge of managing European debts and should be constituted by countries of the euro zone meeting strict conditions, Reuters reported.
