Spanish prime minister Mariano Rajoy is pressing for a direct European rescue for Spain's banks with moral support from the European Commission, but Germany appeared to rule out such a "bailout lite" for the euro zone's fourth biggest member.
A source with knowledge of the matter told Reuters Madrid was working along with European institutions to find a way to directly refinance banks using rescue funds without the government having to come under a full EU-IMF adjustment programme.
"Right now the most urgent issue is the banks, and there are negotiations to refinance the banks directly without it being an intervention. It's a mechanism for all (European) banks, not just for Spanish banks," the source said.
Spain's borrowing costs have jumped in recent weeks, largely due to doubts over whether the government can raise enough funds for the rising bill to strengthen its banks, left with big holes after the 2008 crash of the housing and construction market.
Under current rules Spain can get a loan from the European rescue fund, or EFSF, but it would come with tough conditions and intrusive supervision, with a high political cost for Mr Rajoy. The new permanent European rescue fund, the European Stability Mechanism (ESM), due to enter into force in July, can lend to banks but the request still has to be made by the state.
The source with knowledge of the matter said Spain believed the European Union's executive could take a plan for bank aid to a summit of the bloc's leaders on June 28-29th.
EU Economic and Monetary Affairs Commissioner Olli Rehn said Brussels was considering direct bank recapitalisation by the ESM to break the link between weak sovereigns and ailing banks, but it was not possible under the treaty currently being ratified by member states.
"This is not part of the ESM treaty for the moment, in its present form, but we see that it is important to consider this alternative of direct bank recapitalisation as we are now moving on in the discussion on the possible ways and means to create a banking union," Mr Rehn said.
Germany, the main contributor to the bailout fund, opposes changing the ESM treaty to allow direct bank recapitalisation and has veto power. Berlin contends that only a formal programme approved by national parliaments permits proper international supervision of how aid funds are spent.
"It is only for a national government to decide whether it draws on the rescue mechanism and the requirements that are linked to it. That of course is also true for Spain," government spokesman Steffen Seibert told a news conference when asked about media reports that Berlin was pushing Madrid to apply.
Mr Seibert also said Spain first needed to figure out how much money it needs to recapitalise its banks.
After pressing in vain for the European Central Bank to ride to Spain's rescue by buying government bonds, Mr Rajoy took a different line on Saturday, calling in a speech for a euro zone fiscal authority with powers to manage member states' budget policies, to show markets the euro project is irreversible.
Spain already complies with the terms for the state to tap the temporary European Financial Stability Facility (EFSF) under its "guidelines on recapitalisation of financial institutions".
Those conditions are: it needs the money as a last resort to recapitalise systemic lenders, such as Bankia, and it has also started an independent audit of its banks in two stages.
The ECB and key EU partners such as Berlin are keen to avoid a repeat of last year's events when they had to push Portugal to seek aid after former prime minister Jose Socrates resisted for months owing to the stigma attached to an "IMF bailout".
The ECB stopped buying Portuguese bonds in the secondary market and Portuguese banks took the unprecedented step of warning the government that they too might stop buying its debt -- a move that probably tipped Socrates into seeking help.
The head of Portugal's banking association, Antonio de Sousa, told Reuters in an interview at the time that the ECB had told the country's banks to cut exposure to government debt.
German finance minister Wolfgang Schaeuble insisted then that aid could only be granted in the framework of a reform programme, the same stance Berlin is now taking towards Madrid.
