The greeks and cypriots will tell you all about it, I am pretty sure both England and Sweden have bail in-laws, but I think bail ins really only apply to you if your country doesn't create its own money which is the case with EU members and some dollarised countries, if you're banking system is failing you have to hair cut those with savings directly to stand it up

If you have your own currency you just haircut them through inflation, same outcome, but one isn't so on the nose that people understand, so inflation it is for most of us
