The reserve ratio is a crucial concept for businesses and investors to grasp, especially in the context of monetary policy and banking regulations. It's the percentage of deposits that commercial banks are required to hold in reserve, rather than lending out.
In the United States, for example, the reserve requirement is set by the Federal Reserve. This means that if the reserve requirement is 10%, a bank with $100 million in deposits would be required to hold $10 million in reserves. The remaining $90 million could be lent out to customers.
Understanding the reserve ratio is essential for businesses and investors to make informed decisions about lending and borrowing. It's also a key factor in the overall money supply and economic growth.

What Is Reserve Ratio?
The reserve ratio is a crucial concept in banking, and it's actually quite simple. It's the percentage of deposits that commercial banks must hold in reserve and not lend out.

In most countries, the reserve ratio is set by the central bank. For example, the Federal Reserve in the US sets the reserve ratio at 10% for commercial banks.
This means that if a bank has $100 in deposits, it can only lend out $90, as it must hold $10 in reserve. The reserve ratio can be adjusted by the central bank to control the money supply in the economy.
The reserve ratio helps prevent banks from lending too much money and causing inflation. By requiring banks to hold a certain percentage of deposits in reserve, the central bank can ensure that there is enough money in circulation to meet demand without overheating the economy.

Example with Excel Template
Let's take a look at how to calculate the reserve ratio using an Excel template. The reserve ratio is calculated by dividing the reserve maintained with the central bank by the deposit liabilities. For example, in the case of the ASD Bank, the reserve ratio was 8.0% because the bank maintained a cash reserve of $16 million with the central bank given its deposit liabilities of $200 million.
To make it easier to calculate, you can use an Excel template with the following formula:
Reserve Ratio = Reserve Maintained with Central Bank / Deposit Liabilities
This formula can be applied to any bank's data to calculate its reserve ratio. For instance, in Example #1, the reserve ratio was 8.0%, and in Example #3, the bank was required to add $1 million to its existing reserve to be compliant with the new reserve requirement.
Here's a simple table to illustrate the calculation:
As you can see, the reserve ratio is an important metric for banks to ensure they are meeting the central bank's reserve requirements. By using an Excel template, you can easily calculate the reserve ratio and make informed decisions about your bank's operations.
Explanation and Relevance
The reserve ratio is a crucial concept in banking economics that plays a significant role in maintaining the supply of money in the financial system. It's predominantly used by Central banks to protect banks against a probable shortage of funds in case of bank runs.

The reserve ratio indicates the portion of deposits that commercial banks can't use for lending, which influences the available liquidity in the market. For instance, Central banks tend to increase the required reserve ratio to curb money supply and control inflation.
In the United States, the reserve requirement is not applicable to savings accounts and time deposit accounts, but in countries like the United Kingdom, Canada, Australia, New Zealand, Sweden, and Hong Kong, the statutory reserve requirement has been abolished entirely.
The Cash Reserve Ratio (CRR) has several critical objectives, including controlling inflation, ensuring banks have a minimum level of funds available to customers, serving as the loan's reference rate, and stimulating the economy by lowering the CRR when necessary.
Here are the main objectives of CRR:
- CRR aids in the control of inflation.
- CRR assures that banks have a minimum level of funds available to customers.
- The CRR serves as the loan's reference rate.
- CRR stimulates the economy by lowering the Cash Reserve Ratio.
What Is Cash?
Cash is a certain percentage of deposits that banks have to keep with the RBI as a deposit. This percentage is fixed by the RBI and is changed from time to time by the central bank itself. The current Cash Reserve Ratio is 4.50%, meaning that for every Rs 100 worth of deposits, the bank has to keep Rs 4.5 with the RBI.

Banks have to keep this cash reserve to provide some sort of liquid cash against depositors’ money. This is to ensure that the bank does not run out of cash to meet depositors’ requirements.
Banks do not receive any interest on the money they park with the RBI under CRR. This is a key aspect of the Cash Reserve Ratio.

Explanation
The reserve ratio formula is a crucial tool in banking economics, used by central banks to maintain the supply of money in the financial system. It's calculated by dividing the dollar amount of the reserve maintained by the bank by the dollar amount of its deposit liabilities.
To calculate the reserve ratio, you need to determine the dollar value of the amount held by the bank with its central bank, and the dollar amount of the deposit liabilities against which the bank is obligated to maintain reserves. This is typically found in the bank's financial reporting.

The reserve ratio formula is used to determine the portion of deposits that commercial banks can't use for lending, which influences the available liquidity in the market. By increasing or decreasing the required reserve ratio, central banks can control the money supply and influence inflation.
Here's a breakdown of the reserve ratio formula:
- Reserves / Deposit Liabilities = Reserve Ratio
For example, if a bank has $10 million in reserves and $100 million in deposit liabilities, the reserve ratio would be 10% (10/100 = 0.10). This means that the bank can lend out 90% of its deposit liabilities, or $90 million.
Calculation and Requirements
The reserve ratio is a crucial concept in banking, and understanding how it's calculated and what the requirements are can help you navigate the world of finance.
The reserve ratio formula is simple: Reserve Ratio = Deposits * Reserve Requirement. For example, if the European Central Bank sets a reserve requirement of 8% and a bank has deposits of 2 billion €, the bank must keep 160 million € as a reserve requirement.
In the United States, the Federal Reserve sets different reserve requirements for commercial banks based on their net transaction accounts. For instance, banks with more than $124.2 million in net transaction accounts must keep a reserve of 10% of net transaction accounts.
Reserve requirements are intended to prevent banks from generating too much money by making too many loans against a narrow money deposit base, and to ensure that banks have sufficient supplies of highly liquid assets to maintain public confidence.
Here are some examples of reserve requirements in different countries:
In fractional-reserve banking, the reserve ratio is calculated by dividing the cash reserves held by the bank by the demand deposits. For example, in the case of ANZ National Bank Limited, the cash reserves are NZ$3,010m and the demand deposits are NZ$25,482m, resulting in a cash reserve ratio of 11.81%.
Banks must maintain a minimal reserve ratio to avoid defaulting on their obligations, and they can respond to falling ratios by selling or redeeming assets, restricting new loans, borrowing funds, or issuing additional capital instruments.

Effects and Consequences
The reserve ratio has a significant impact on the economy. A higher reserve ratio can lead to a decrease in the money supply, causing a contraction in economic activity.
A higher reserve ratio means that commercial banks have to keep a larger portion of deposits in reserve, rather than lending them out, which can lead to a decrease in the amount of money circulating in the economy. This can have a ripple effect, causing businesses to reduce production and employment, leading to a recession.
A decrease in the money supply can also lead to higher interest rates, as banks raise their rates to attract more deposits. This can make borrowing more expensive for consumers and businesses, further exacerbating the economic downturn.

Effects of Change
Changes to the Cash Reserve Ratio (CRR) can have a significant impact on the economy. If the CRR is too high, banks have less money to lend or meet depositor requirements, indicating low liquidity in the economy.

Relaxing CRR restrictions can infuse liquidity into the economy by leaving more money with the banks. This, in turn, can affect interest rates in the economy.
Penalties for failing to maintain the required CRR limit are severe. Banks that default on CRR will have to pay fines to the RBI, charged at 3% per annum above the bank rate on the shortfall.
The penalty can increase to 5% per annum above the bank rate if the bank continues to default. This penalty is also charged on the shortfall and for the concerned number of days of the shortfall.
Reserves are a crucial part of the banking system. Banks must hold a certain percentage of their deposits as reserves, which cannot be loaned out. For instance, with a 10 percent reserve requirement, a bank that encounters a net increase of $200 million in deposits would be required to build its necessary reserves by $20 million.
The remaining $180 million can be loaned out, increasing bank credit. As those assets are loaned, they create extra deposits in the financial system.

Instability
Instability has been a persistent issue in the banking system. Irving Fisher proposed a system of full-reserve banking in 1935 to reverse deflation during the Great Depression.
This system would give the central bank, such as the Federal Reserve in the US, more direct control over the money supply. Banks would only lend from time deposits, not from demand deposits.
Fisher's proposal aimed to stabilize the economy by limiting banks' ability to create new money through lending.

Return
The return on reserve requirements is a crucial aspect of banking in the USA.
The Federal Reserve Board of Governors has the sole authority to change reserve requirements, as seen in the January 2019 update.
Banks with more than $124.2 million in net transaction accounts must keep a reserve of 10% of net transaction accounts.
Here's a breakdown of the reserve requirements for different bank sizes:
- Banks with more than $124.2 million: 10% reserve
- Banks with $16.3 million to $124.2 million: 3% reserve
- Banks with up to $16.3 million: 0% reserve (most banks fall into this category)
- Nonpersonal time deposits and eurocurrency liabilities: 0% reserve
The reserve requirement is inversely related to the money multiplier, m.
