What's a Slovenian with several hundred thousand euros in the bank supposed to do? Spread it out among at least a few different banks, that's what. Or move the money out of the country, while it's still possible.

Imagine what must be on the minds of any savvy depositors still left at Nova Kreditna Banka Maribor d.d., now 79 percent-owned by Slovenia's government. It was one of only four lenders in October that failed the European Banking Authority's latest capital-adequacy test, a ritual best known for how lax its standards are. One that flunked was Bank of Cyprus Pcl, where uninsured depositors face 40 percent losses as part of the country's bailout terms. Another was Cyprus Popular Bank Pcl, also known as Laiki Bank, where uninsured deposits will fare far worse and the bank is being shut.

Cypriot banks' customers were complacent after uninsured deposits went unscathed in Ireland, Greece, Spain and Portugal, the first euro-area countries to seek international rescues. Slovenians won't have that excuse should their country be next.
