Concretamente:
IOU viene de "I owe you", yo te debo y son cartas de pago de distintos tipos.
Aquí esta el meollo de la cuestión:
How are they created?
Unlike currency, which is created by the Bank of England, bank deposits are mostly created by commercial banks themselves . Although the stock of bank deposits increases whenever someone pays banknotes into their account, the amount of bank deposits is also reduced any time anyone makes a withdrawal. Moreover, as Chart 1 shows, the amount of currency is very small compared to the amount of bank deposits. Far more important for the creation of bank deposits is the act of making new loans by banks. When a bank makes a loan to one of its customers it simply credits the customer’s account with a higher deposit balance. At that instant, new money is created.
