I was talking to a friend tonight who told me that ING nearly went under during the GFC. I have a bit of money with them, and I had no idea they were in trouble (although admittedly, I wasn't too interested in finance back then).
So it made me think: how safe are banks when it comes to safe keeping our money? I seriously don't know anyone who would be likely to keep a tin box of cash under their bank. Everyone seems to keep it in an account of some sort - so if banks go down, then do we really lose all our money?
