Lake says Chase will be passing along those increased expenses to customers, which would put an end to now-free services such as checking accounts and wealth management tools. And she says she expects other banks will follow suit.
Correct, the principal is essentially destroyed on payment. Once the loan is payed off, all the money that the bank had originally created has been destroyed.
