We need to stop this financial hocus-pocus!
If there is anything rational for the regulators to do now it would be to swallow their pride and require the same percentage of capital for all credits; give the banks some time to orderly adjust to this; and let the markets price the risk of the banks, for instance by forcing the banks to issue subordinated debt as was suggested by the Shadow Financial Regulatory Committee back in 2000.
To top it up, based “the bigger they are the harder they fall” I would also add some additional progressive capital requirements or insurance payment based on size.
