Spain’s banking sector is the focal point for worries about its economy, and the only part of the Spanish economy to request a bailout from the rest of the euro zone so far.
Now under new rules being drawn up, the state may be able to intervene and shut down troubled banks, potentially setting shareholders up for hefty losses (Read more: New Spanish Banking Laws).

Some of its smaller, weaker, more property-focused banks should be allowed to bite the dust to stop the size of the country’s bailout escalating even further, according to Ralph Silva, managing director of Silva Research Network.
“People are getting into worse and worse positions month after month in the property market, and most of these smaller lenders are just mortgage lenders,” he told CNBC Europe’s “Squawk Box” Friday.
“Spain needs an orderly disbanding of these financial institutions or the amount of money it would need would be enormous. This is the first regulator in Europe that’s saying this isn’t working, let’s work out another way of doing it.”
The euro zone has already committed around 100 billion euros ($125 billion) to bailing out Spain’s banks, many of whom have run into trouble as the clouds over the Spanish property market failed to dissipate.
“The whole point of the bailout cash is to maintain the banks as a going concern – why let them go bust?” Moorad Choudhry, head of treasury for the corporate banking division at RBS, asked.
Silva argued that the ultimate bill could be much larger if banks are not allowed to collapse.
He believes the Bank of Spain will manage to limit the bill to around 200 billion euros by using similar tactics to U.S. mortgage lenders Freddie Mac and Fannie Mae, which were put into conservatorship by the government at the height of the credit crisis.
He argued that “good” customers like individual savers could be moved to “good” banks so that individual customers could be protected from a bank’s collapse.
