The M1 money multiplier decreases and the money supply decreases when the required reserve ratio on checkable deposits rises, all else being equal.
<h3>What is the reserve ratio?</h3>
The percentage of deposits that commercial banks must retain in cash under the guidance of the central bank is known as the cash reserve ratio.
<h3>How is reserve ratio determined?</h3>
- The country's central bank, in the instance of the United States, the Federal Reserve, determines the reserve ratio requirement.
- The calculation for a bank can be obtained by dividing the bank deposits by the cash reserve held with the central bank, and it is expressed as a percentage.
<h3>What is an example of the reserve ratio?</h3>
The required reserve ratio is directly correlated to how much a bank expands the money supply. For instance, if a bank has deposits totaling $1,000,000 and a reserve ratio of 10%, it can lend out $900,000.
