Customers of Spanish banks still have reason to worry about the solvency of their banks — and their country — making it reasonable for them to take their money from Spanish banks and send it to banks in safer countries like Germany. Indeed, the bailout makes it less likely Spain can pay back its debts because the new loan of up to $125 billion was just added to its huge debt pile. Worse, Spanish banks had been the biggest buyers of Spanish debt (a farce of a way to prop up the economy) and that most likely won’t continue.
As a result, it could be argued that it would be irresponsible for an individual or company, which has a fiduciary duty to its shareholders, not to move its money out of Spanish banks. Of course, money leaving the banks can become a self-fulfilling vicious cycle that virtually no amount of bank bailouts can plug. (By the way, countries like Spain have their own version of F.D.I.C., but it is all but worthless if you believe the country could collapse under its own debt.)
