# Understanding Cash Reserve Ratio: Definition, Calculation, and Impact on the Economy

Updated: May 3, 2023

In the world of banking, there are several terms that are important to understand, especially for individuals who want to learn more about the financial system. One such term is the Cash Reserve Ratio (CRR), which refers to the percentage of deposits that banks are required to keep with the central bank. This article aims to provide a comprehensive understanding of the CRR, its calculation, and its impact on the economy.

## What is Cash Reserve Ratio (CRR)?

Cash Reserve Ratio, also known as Reserve Requirement Ratio (RRR), is the percentage of deposits that banks are required to keep with the central bank of a country. This is a monetary policy tool that central banks use to control the money supply in the economy. By adjusting the CRR, the central bank can influence the amount of money that banks have available to lend to consumers and businesses.

## How is Cash Reserve Ratio (CRR) Calculated?

The CRR is calculated as a percentage of a bank's deposits, which includes demand deposits, time deposits, and savings deposits. The formula for calculating the CRR is as follows:

CRR = (Amount of Reserves Held by Banks / Amount of Deposits) * 100

For example, if a bank has deposits of \$100 million and it is required to keep a CRR of 10%, it would need to keep \$10 million with the central bank.

## Why is Cash Reserve Ratio (CRR) Important?

The CRR is an important tool used by central banks to regulate the money supply in the economy. By increasing or decreasing the CRR, the central bank can influence the amount of money that banks have available to lend to consumers and businesses. If the central bank wants to increase the money supply, it can decrease the CRR, which would give banks more money to lend. On the other hand, if the central bank wants to decrease the money supply, it can increase the CRR, which would reduce the amount of money that banks have available to lend.

## Advantages of Cash Reserve Ratio (CRR)

1. Control over money supply: The CRR gives central banks the ability to control the money supply in the economy, which is essential for maintaining economic stability.

2. Reduced inflation: By increasing the CRR, central banks can reduce the amount of money that banks have available to lend, which can help to reduce inflation.

3. Prevents bank failures: The CRR ensures that banks have a sufficient amount of reserves to cover any unexpected losses, which can prevent bank failures.

## Disadvantages of Cash Reserve Ratio (CRR)

1. Reduced profitability: Banks are required to keep a certain percentage of their deposits with the central bank, which reduces the amount of money they have available to lend, and in turn, reduces their profitability.

2. Increased interest rates: If the CRR is increased, banks may have to increase their interest rates to compensate for the reduced amount of money they have available to lend.

3. Reduced economic growth: If the CRR is increased, it can reduce the amount of money available for lending, which can reduce economic growth.

## Impact of Cash Reserve Ratio (CRR) on the Economy

The CRR has a significant impact on the economy. By controlling the money supply, the central bank can influence interest rates, inflation, and economic growth. If the central bank decreases the CRR, it can increase the amount of money available for lending, which can lead to lower interest rates and increased economic growth. On the other hand, if the central bank increases the CRR, it can reduce the amount of money available for lending, which can lead to higher interest rates and reduced economic growth.

## Conclusion

The Cash Reserve Ratio (CRR) is an important tool used by central banks to regulate the money supply in the economy. By adjusting the CRR, the central bank can influence the amount of money that banks have available to lend to consumers and businesses, which in turn can impact interest rates, inflation, and economic growth.

While the CRR has advantages such as providing control over the money supply and preventing bank failures, it also has disadvantages such as reduced profitability for banks and potential for reduced economic growth.

Overall, the CRR plays a crucial role in maintaining the stability of the economy, and it is important for individuals to understand its definition, calculation, and impact on the economy.
