♦ But because the business is risky, the same banker must also emphasize safety.

♦ The heart of banking is to be torn between the two principles.

Banks and Money CreationBanks and Money Creation

● The Limits to Money Creation by a Single Bank♦ Banks can lend money in their vault that is

above the minimum required reserve ratio.

♦ In doing so, they create new money.

● Multiple Money Creation by a Series of Banks♦ When all banks make loans with funds they

have that are above the required reserve ratio, the society’s money supply expands.

● The Process in Reverse: Multiple Contractions of the Money Supply♦ Deposits, and with them the money supply,

contract when reserves are reduced.■Banks reduce their loan commitments.■Calculation of the contraction in the money supply

utilizes the same formula as for money expansion.

The Need for Monetary PolicyThe Need for Monetary Policy

● Left uncontrolled, banks would: ♦ Reduce the money supply in a recession♦ Increase the money supply during boom

periods

● Changes in the money supply would exacerbate the business cycle.

● One reason for monetary policy, therefore, is to prevent this behavior on the part of banks.
