BRUSSELS — The European Union worked towards stabilizing Spain’s finances Tuesday as it backed up the blueprint for the country’s (euro) 100 billion bank bailout plan with plans to grant the country an extra year to cut its budget deficit.

Finance ministers from the 27 EU countries, meeting in Brussels, approved a one-year extension, until 2014, of Spain’s deadline for achieving a budget deficit of 3 percent, said Vassos Shiarly, Cyprus’ finance minister, who chaired the meeting because his country holds the EU’s rotating presidency.

The move comes on the heels of an overnight meeting at which the 17 euro area finance ministers agreed on the terms of a bailout for Spain’s troubled banks, saying that the first (euro) 30 billion ($36.88 billion) in aid can be ready by the end of this month.

The finance ministers for the 17 countries that use the euro will return to Brussels on July 20 to finalize the agreement, having first obtained the approval of their governments or parliaments, eurozone chief Jean-Claude Juncker said.

Last month, the eurozone’s finance ministers agreed to offer Spain up to (euro) 100 billion to prop up its stricken banking sector, which has been weakened by toxic loans and assets from a collapsed property market.

Meanwhile, Greece’s new finance minister, Ioannis Stournaras, said his country will work to get its budget-balancing program back on track, but Greece too will need extra time to meet its targets.

“I think the size of the recession justifies, as Spain got an extension, that we should ask for an extension,” Stournaras said. He said he recognized it was still too early to expect a formal decision on the issue.

Investors — who had been concerned about the terms of Spain’s bailout deal and the lack of fine detail in decisions made at the June 28-29 summit in Brussels — tentatively welcomed news of Monday night’s decisions. Markets across Europe showed slight gains early Tuesday afternoon. In Madrid, the country’s main IBEX index rose 1 per cent to 6,756.10 while the borrowing cost of its 10-year bond dropped from 7.03 per cent Monday to 6.78 percent. France’s CAC 40 was up 0.73 percent at 3,180.06 and Germany’s DAX had risen 0.88 percent to 6,443.33.

Juncker added that the Spanish deal will mean each bank that receives a bailout will be forced to adopt specific conditions, and the supervision of the financial sector overall will be strengthened.

“We are convinced that this conditionality will succeed in addressing the remaining weakness in the Spanish banking sector,” he said.

Dutch Finance Minister Jan Kees de Jager said the agreement should be finalized soon.

“The total will likely be (euro) 100 billion. Some countries like the Netherlands, Germany and Finland need to get parliamentary approval,” De Jager said. “We hope this can be wrapped up within a week.”

The exact amount of the bailout will likely not be known until September, when individual examinations of different Spanish banks have been completed.

Spain — the fourth-largest economy in the eurozone — has been struggling to keep a lid on its government deficit in the midst of a recession while trying to support its troubled banking industry. There are fears that should Spain need a bailout of its own, the eurozone would struggle to finance it, pushing the region further into recession.

De Jager said Madrid’s partners agree that “financial sector reforms in Spain must be ruthlessly implemented. These reforms include, notably, a cap on salaries of bank executives and a ban on bonuses.”

However, he said a system of EU-wide banking supervision still needs to be worked out.

But on Monday, before the eurogroup meeting began, Mario Draghi, the chief of the European Central Bank, said he was confident that a banking union in the European Union would be achieved.

“The first thing to be created will be the supervision,” Draghi told a committee of the European Parliament. “We are talking about the long-term sustainability of the European monetary union. We are going as fast as we can. It is better to do things right than in a hurried fashion. We certainly want to see this thing wrapped up by the end of the year,” he said, referring to banking oversight.

EU Economic and Monetary Affairs Commissioner Olli Rehn said the European Commission would put forward legislative proposals for the creation of a “Single Supervisory Mechanism” for banks in the euro area, involving the European Central Bank, in early September. The creation of the central bank supervision will allow the EU’s firewall fund to recapitalize banks directly rather than lending the money to a country’s government — something that increases the country’s debt load.

“Direct bank recapitalisation will enable us to break the vicious circle between banks and sovereign risk,” Rehn said.

Ministers added the final decision on Greece’s request to renegotiate the terms of the country’s bailout agreements will depend on the conclusions of the so-called “troika” of debt inspectors currently overseeing the Greek program.

Greece has had to impose harsh austerity measures, including big cuts to pensions and salaries, to secure billions of euros worth of rescue loans from the IMF and other European countries that use the euro and avoid bankruptcy.

The finance ministers also reelected Juncker to a new 2 1/2 -year term as president of the eurogroup. But Juncker said he  would step down late this year or early next year.
