It’s a good question, and I agree that common sense suggests it should be up to €100k in any currency. However, there’s not much common sense around these days, and anyway, I’m not going to make an effort to find out the answer for the following reason: I don’t think the deposit guarantee will help anyone in this crisis, regardless of currency. It is there to give us the illusion that our savings are safe. If banks start to fold there isn’t anywhere like enough money to go around. People will not get back what has been guaranteed.
