Storing cash in a safety deposit box has always been a no-no, but it appears that this is the year that the banks will not allow cash payments (US $100 bills essentially) for larger mortgage payments, credit cards, auto and regular loans.
I can imagine they will institute a maximum $ per day, like you can only pay $500 in bills each day to pay off any type of loan. Sort of like how you can only use a maximum amount of coinage to pay off a debt.
This will greatly reduce the circulation of cash, which of course is the ultimate goal to keep everyone under a taxable roof (some say, that the reduction and restrictions in circulation of cash may just end up destroying the entire economy) Time will tell whether this is a good idea or not.
I say its going to fuck things up royal.
