For anyone who doesn't understand banking jargon, the Federal Reserve is effectively changing what banks are allowed to put towards their capital requirements. This is to implement the global banking standard known as Basel III.
Basically, the regulation requires banks to hold about 30-50% more capital on hand than they currently do. The goal is to turn "too big to fail" into "too strong to fail".
That's a fine goal, but forcing banks to have more capital on hand is going to have some pretty bad consequences for the rest of us.
1) It's been shown time and again that regulation costs get passed on to consumers. In this case, we can all expect higher interest rates on loans while our savings and CD rates go nowhere. In this case, banks will have less money to lend out but will be attempting to make the same profits.
2) It doesn't address the source of the problem. The thing that brought big banks to their knees wasn't undercapitalization. Instead it was the fact that regulatory pressures were pushing them to avoid risk. So instead, banks would invest in the lowest risk with the highest return, even if the risk was actually unknown.
In short, we can all expect higher interest rates on our loans with nothing actually being accomplished.
Oh yeah, and this measure is also expected to slow GDP growth by up to .15%.
