The facts are now well known. The largest banks in Cyprus are insolvent, but too big for the government of Cyprus to save – at least if it wanted to avoid the ‘double drowning’ fate of Ireland. The government, trying to rescue banks, found itself needing a rescue...
Even though it wasn’t adopted, the extraordinary proposal that small depositors should lose a part of their savings – a proposal that had the approval of the Eurogroup, ECB and IMF policymakers – raises the question:
The Iceland precedent
Cyprus is not the first time deposits security came into doubt. When the Icelandic bank Icesave went down, the relevant court ruled that the Icelandic government was not legally obligated to repay UK and Dutch depositors in a timely fashion (EFTA Court 2013). Here is the key:
Lessons: Deposit insurance as a political vs legal commitment
The Cyprus and Iceland lesson is clear:
Consider the ex-ante ability of Cyprus and Iceland to assure their bank deposit:
Looking at this, and noting the precedents set in Iceland, it seems clear that these deposits were not insured for the case of systemic failure...
Avoiding bank runs
A third argument that is sometimes made is that deposit insurance prevents contagion. That is, if depositors at failed banks are forced to take losses then there may be runs on solvent banks as well. The idea is that if each depositor believes that all other depositors will run and as a consequence an otherwise solvent bank will fail, then it is optimal for each depositor to run as well. As a result the bank fails. Observing depositors lose their money at a failed bank is the sort of event that might coordinate the beliefs of depositors of solvent banks in such a fashion.
But the argument misses an important point. There are other ways to prevent self-fulfilling bank runs. Runs on solvent banks can be prevented or their effects mitigated by having a central bank such as the Eurosystem that is a credible lender of last resort. This argument alone provides no need for transfers from either taxpayers or other credit institutions to any of the creditors of a failed bank.
Conclusion
If the EEA wants to provide credible deposit-insurance schemes that cover the collapse of large banks or (not too large) banking systems, then it needs schemes that are jointly and severally funded. However, it is unreasonable to expect the area as a whole to bail out a particular country’s banks unless it can also supervise that country’s banks. This is problematic for the EEA or even the EU, but it may be possible – at least in the eurozone – when and if the single supervisory mechanism comes into being.
