I don’t see the proposed solution as being anything but fair. The banks were failing. Some had to be closed. The first 100k is secure as per the insurance agreement. Bond holders are toast. But this is much more fair that hitting taxpayers and savers with less than 100k.
Every time I exceeded the insurance limits here in the US, I opened a new account at a new bank and moved money to the new account so all my funds would continue to be insured.. I’m not sure how it works in the EU, but here the insurance is per bank and there is no limit to the number of accounts one can have a different banks.
One would assume that anyone with more than 100k would understand the responsibilities and risks, excepting the very few who may have been snagged with large transactions that occurred in this 2-week period.
