|Money as Credit
Money does not
exist in a pure barter system.
Trades are negotiated
by the participants as a fair exchange of goods and services. If
agrees to receive equivalent value later in exchange for his goods, he
accepted an IOU.
An IOU is a credit
for the seller and a debt for the buyer. If the IOU becomes

IOUs as Money
Money is the
credit side of a balance sheet
relation. Every dollar of credit is matched by an equal amount of
debt. A bank loan creates a credit for the borrower in the form
of a negotiable IOU
(the deposit) and a matching debt (the obligation to repay the

equal liability (the negotiable IOU).
The term money
is sometimes used in reference to high quality debt
nearing maturity. However such near-money
is seldom acceptable as a medium
of exchange. Besides being inconvenient to the seller, the
of near-money is not really known until sold in the marketplace.

Fed Funds and Bank Money
When the Fed
purchases a financial asset
from the public, it credits the seller's bank with a deposit at the
funds. Banks can exchange Fed funds for
Reserve notes, and vice versa, on

taxes. Conversely the government pays in Fed funds when it

with bank money, i.e. a check against a bank deposit. However the

IOUs. Thus bank deposits are nearly as negotiable in the private
as Fed funds. Private party IOUs may be legally binding, but they

accounts similar to checking accounts at banks. They are actually

A bank can

deposits without adequate reserves, and count on borrowing to meet the
requirement. That may leave the banking system short of reserves,

In order to defend its target interest rate, the Fed will supply the

Non-Banks as Intermediaries
were once the main source
of credit. Today NBFIs such as mutual funds, pension funds,
companies, and insurance companies issue far more credit in total than
banks. Indeed, deposits created by banks now comprise less than
the total credit market debt.
