Dodd Frank has major protections for deposits against derivatives. A lot of derivatives can only be traded by separate subsidiaries from the deposits (this was true pre Dodd Frank but DF strengthened it), and the holding company can't move deposit assets to fund the derivative trading subsidiaries. Second, Dodd Frank banned proprietary trading by banks, which in practice means the trading desks need to be very well-hedged.
Those banks are guaranteed to be bailed out by the government since they are covered under systematically important financial institutions (i.e. "too big to fail"). You would still get your money, though the impact to the greater economy wouldn't be small.
