This video is a good presentation, but its description of money creation is incorrect: Commercial banks do not have any right to create money, they can only sell assets to central bank in exchange for money, they can not loan out money more than they already have
The money creation only happened at central Bank, and there is no FRB at central bank
Yes they can and do. It is called double entry book keeping and it expands the money supply the fed only creates a small amount of the money supply the vast majority of money is created when banks lend money into existence,
