Quote from Martinghoul:
Well, it may be efficient to backstop "some" deposits in the interest of having a banking system that is not completely reliant on the state during times of stress. However, it's also very true that too much of a good thing can breed moral hazard and introduce other unpleasant issues. So in this case, like with most other things in life, it's important to find the right balance.
Furthermore, you could, sorta, argue that you could, in theory, make the deposit insurance levy a tax on the banking industry, rather than the taxpayer. If the banking industry in the US weren't so concentrated and not particularly competitive, that might actually be the case.
Generally, I can point you to a couple of really good papers that discuss these issues and that can make the case a lot more eloquently.
Wait - why is efficiency important? I didn't offer to pay for someone else's idea of efficiency. Why is the state allowing the banking system to rely on it during times of stress? You are just skirting around the issue I raised - why should banks get a special subsidy in times of stress, one that is denied to ball-bearing manufacturers or panel-beaters for example? Or even hedge funds - if they go bust, they don't get a bail out.
The only reason I can think of is that the societal disruption is so large that it become politically untenable. But if that is likely to be the case (clearly true in the current system), then the system needs to be changed so that is not the case...NOT tweaked so other people fund it (under forcible coercion i.e. tax payments) to make it a bit less bad.
Remember that the deposit insurance limits will not be 'hard' limits, but are subject to whimsical change up, down, or to infinity (e.g. Ireland) based on the backroom dealings and poll numbers of a small number of not-disinterested bankers and politicians, along with the baying lynch mob of the pissed-off public. The fact is, that system is so unstable in crises that all bets are off once one arises. No one will be interested in an academic paper when the shit is hitting the fan, they will be scared and interested in political survival, avoiding loss of life savings, business bankruptcy etc.
For example, what if this EU proposal had existed worldwide in 2005? Are we to believe that in the heat of the 2008 panic, the rules would have been followed? Or would some numbers have been plucked out of someone's arse?
The problem is not that the banking system periodically goes bust. The problem is people expecting it not to, when it clearly runs a predictable risk of doing so due to its highly leveraged nature, and its tendency to get exposure to speculative manias.
What about a shift to a system that would avoid, or seriously reduce this risk, without requiring an arbitrary hidden taxpayer subsidy? For example: a government owned or backstopped bank (or class of banks) which invests purely in t-bills, and charges a fee for handling normal day to day banking operations. All other banks are pure caveat emptor for everyone including depositors. If a private scheme wants to insure them, go ahead - but no tax-funded insurance.
Or, only offer deposit insurance to full-reserve banks. Clearly explain the difference. Then, anyone who chases yield by investing in the fractional reserve sector, has no grounds to moan when it blows up again.
