The amount of money kept in the reserve account of a bank (as a requirement) to allow for continued functionality What is Deposit Multiplier?The deposit multiplier is essentially the amount of money kept in the reserve account of a bank (as a requirement) to allow for continued functionality, to meet the withdrawal demands of their clients, and to limit the potential risks associated with the depletion of their supplies. The deposit multiplier is the ratio of the checkable deposit to the amount in the reserves.  Generally, banks hold a maximum amount of money that they can create as a percentage of their reserves, which is set forth by the fractional reserve banking system. As banks loan out their reserves, they produce checkable deposits and estimate the amount of money that is available to be lent out by using their reserve requirement ratio. Hence, the deposit multiplier can be seen as the opposite of the reserve requirement ratio, because it is a ratio of the checkable deposit to the amount in the reserves. An example of such an inverse relationship is when a bank posts a required reserve ratio of 24%, the deposit multiplier would be 76%. The deposit multiplier allows for the bank to ensure that there is sufficient cash to cater for withdrawals, as needed by the customers. In some instances, the deposit multiplier can be presented as the deposit multiplier ratio. The deposit multiplier aids in ensuring the basic money supply in an economy. Summary
Understanding Deposit MultiplierAlso known as the simple deposit multiplier or the deposit expansion multiplier, the deposit multiplier is essentially the amount of money kept in the reserve account of a bank (as a requirement) to allow for continued functionality. It allows the bank to meet the withdrawal demands of their clients, and to limit the potential risks associated with the depletion of their supplies. As a pivotal part of the banking system, central banks (e.g. the U.S. Federal Reserve) put forth a required reserve. The required reserve is the minimum amount of money to be held by a bank, which can be lent out to the bank’s respective customers. Banks are expected to maintain the required reserve in an account that is held at the central bank. The deposit multiplier, as emphasized before, is the opposite of the required reserve. It is the ratio of a bank’s checkable deposits, and it sets forth the foundation for the money multiplier, but the money multiplier is significantly smaller. Understanding Checkable DepositsBank accounts against which checks can be written out to facilitate a withdrawal are known as checkable deposits. Such accounts can be considered to be liquid assets as they provide ease of access for their clients. Examples include money market accounts, interest-bearing accounts, and deposit accounts. Understanding Money MultiplierThe amount of money generated by banks in conjunction with each dollar of reserves is known as the money multiplier. To better understand the concept, consider a country where the central bank imposes a 15% reserve requirement. The reserve ratio is 1/15; it means that for every $1 deposit in the bank, $0.85 can be loaned out. Thus, given a bank with $200 million worth of deposits can loan out $170 million. It increases the money supply from $200 million to $370 million. The money multiplier can provide information on how quickly the money supply (from a bank’s lending) will grow. A high reserve ratio indicates that fewer deposits are available for lending, thus producing a lower money multiplier. It presents an inverse relationship between the reserve ratio and the money multiplier. Deposit Multiplier FormulaThe following is the formula for determining the deposit multiplier ratio: For comprehensive purposes, consider the example of Bank ABC, which keeps a required reserve ratio of 12%. How does one determine the deposit multiplier? The deposit multiplier can be computed by dividing 1 by the reserve ratio of 10% to get the deposit multiplier of 10. It shows that for every $100; $1,000 is created.

An increase in the reserve ratio leads to a decrease in the money supply, driving interest rates up and pulling nominal GDP downward.
What is the inverse of the required reserve ratio?The deposit multiplier is the inverse of the reserve requirement ratio. A deposit multiplier minimizes the risk of a bank not having enough cash on hand to satisfy day-to-day withdrawal requests from its customers. Its reserve requirement ratio also determines how much money it has to loan out or otherwise invest.
What happens to money supply when required reserve ratio increases?Reserve Requirement Changes Affect the Money Stock
Increasing the (reserve requirement) ratios reduces the volume of deposits that can be supported by a given level of reserves and, in the absence of other actions, reduces the money stock and raises the cost of credit.
What is the relationship between the reserve ratio and the money multiplier inverse or direct?It tells the maximum number of times the amount will be increased with respect to the given change in the deposits. The money multiplier has an inverse relationship with the Legal Reserve Ratio (LRR).
