My guess is that whilst BNBG rates higher than shareholders, I believe that it falls behind banks in the queue for funds in the event of liquidation.
If you were a punter you'd probably think that there is less than a 100 to 1 chance of BNB surviving in it's current form. That being the case you'd be reluctant, to pay more than $1.00 per security. (At least until BNB can get the required asset sales and funding in place for survival).
