Definition of Deposit Multiplier 💰
The deposit multiplier refers to the maximum amount of money that a bank can create in the form of checkable deposits for each unit of currency it holds in reserves. This multiplier is influenced primarily by the reserve requirement set by the Federal Reserve, determining the percentage of deposits that can be loaned out. Essentially, the higher the reserve requirement, the lower the deposit multiplier, and vice versa.
Main Characteristics:
- It is a fundamental concept in fractional reserve banking.
- It allows banks to lend out most of their deposits while holding a fraction in reserve.
- Helps maintain the basic money supply in an economy.
Deposit Multiplier vs Money Multiplier Comparison
| Feature | Deposit Multiplier | Money Multiplier |
|---|---|---|
| Definition | Maximum creation of deposits from reserve | Total change in the money supply due to loans |
| Formula | 1 / Reserve Requirement | Change in Money Supply / Change in Reserves |
| Focus | Bank’s ability to create money | Overall impact on the economy’s money supply |
| Application | Banking system | Broad economic analysis |
Example
Let’s say the reserve requirement set by the Federal Reserve is 10%. This means banks can loan out 90% of deposits.
- If a bank has $100 in reserves, it can legally create up to $1,000 in deposits.
- Calculation: Deposit Multiplier = 1 / Reserve Requirement. In this example: Deposit Multiplier = 1 / 0.10 = 10.
