Call me crazy, but if my bank tells me that my deposits are in safe assets like treasuries, but then the CEO takes the money to Vegas and puts it all on red, even if the CEO wins that bet, I'm very ok with that CEO going to jail.
Of course, if the bank is upfront that they take customer deposits to Vegas, then its fine.
Or if they took my deposit and commingled it with company funds and bought some illiquid luxury real estate in the Bahamas for their staff to live in totalling $240m. If they’re upfront about that, probably nobody deposits with them.
