For a variety of reasons, a bank sometimes will hold more reserves than is legally required. These reserves are known as excess reserves. How does holding excess reserves affect the money supply? Choose one:

(A) The money supply will increase as banks loan out more money.
(B) The money supply will increase as banks hold more vault cash.
(C) The money supply will increase as a bank’s vault cash falls.
(D) The money supply will decrease as banks loan out less money.
(E) There is no impact. The level of deposits and loans will be unaffected.

Banks are lending their deposits and increasing the economic supply of money. Nevertheless, if the bank holds more money and invests less then the supply of money into the economy rises.

Conversely, the ratio increased, boosted, lowered the cash multiplier, and decreased the supply of money. Expansionary fiscal policy is the decrease in the necessary reserve ratio; contraction monetary policy is the rise in the reserve ratio.

When attempting to control the monetary supply, the Fed has two challenges. Firstly, the Federal does not regulate the amount of cash families want to keep in their accounts as deposits. The second problem seems to be that the banks ' capital is not verified by the Fed. If the banks opt for more excess reserves and deposits, the sum of money will be lower.
