What Is Money Creation by Commercial Banks Class 12: Explained Simply

Understanding Money Creation by Commercial Banks

Money creation by commercial banks refers to the process where banks create new money by issuing loans and advances. When a bank receives deposits, it keeps a part of it as reserves (cash with the bank) and lends out the rest. This lending creates new deposits in the banking system, effectively increasing the total money supply.

In Class 12 Economics, this process is crucial to understand how the banking sector influences the economy. Money creation is not about printing currency notes but about expanding the deposit money through credit.

Key points:

• Banks accept deposits from customers.
• They keep a fraction as reserves (called the cash reserve ratio or CRR).
• The remaining amount is lent to borrowers.
• Borrowers spend this money, which gets redeposited in banks.
• This cycle continues, multiplying the money supply.

This process is also called the "credit creation" function of commercial banks.

The Role of Reserve Ratio in Money Creation

The reserve ratio, set by the Reserve Bank of India (RBI), determines the fraction of deposits banks must keep as reserves. This ratio limits how much banks can lend and thus affects money creation.

For example, if the reserve ratio is 10%, banks must keep ₹10 out of every ₹100 deposited and can lend ₹90.

The formula to calculate the maximum money creation is:

$$\text{Maximum Money Created} = \frac{1}{\text{Reserve Ratio}} \times \text{Initial Deposit}$$

For instance, with a reserve ratio of 10% (0.1) and an initial deposit of ₹1,000:

$$\text{Maximum Money Created} = \frac{1}{0.1} \times 1000 = 10 \times 1000 = ₹10,000$$

This means the banking system can create up to ₹10,000 through repeated lending and depositing cycles from an initial ₹1,000 deposit.

The lower the reserve ratio, the higher the money creation potential, and vice versa.

Step-by-Step Process of Money Creation

Let's understand the money creation process with a simple example:

1. Initial Deposit: A customer deposits ₹1,000 in Bank A. 2. Reserve Holding: Bank A keeps 10% (₹100) as reserves. 3. Lending: Bank A lends ₹900 to a borrower. 4. Spending and Redeployment: The borrower spends ₹900, which is deposited in Bank B. 5. Bank B's Reserve: Bank B keeps 10% of ₹900 (₹90) and lends ₹810. 6. Cycle Continues: This cycle repeats, creating more deposits and loans.

This process continues until the loan amount becomes negligible.

Formula for Total Money Supply:

$$\text{Total Money Supply} = \text{Initial Deposit} + \text{Money Created}$$

Or simply,

$$\text{Total Money Supply} = \frac{1}{\text{Reserve Ratio}} \times \text{Initial Deposit}$$

Difference Between Money Creation and Printing Money

It's important to distinguish between money creation by commercial banks and printing money by the government.

Money creation increases the money supply through credit, while printing money increases the physical currency. Both affect the economy differently and are regulated carefully.

Importance of Money Creation in the Economy

Money creation by commercial banks plays a vital role in India's economy, especially for Class 12 students to understand its impact:

• Promotes Economic Growth: By providing loans, banks enable businesses to invest and expand.
• Increases Credit Availability: More money in the system means easier access to credit for consumers and entrepreneurs.
• Controls Inflation: RBI adjusts reserve ratios to control money supply and inflation.
• Supports Government Policies: Helps implement monetary policies effectively.

However, excessive money creation can lead to inflation, so RBI carefully regulates it through tools like CRR and SLR (Statutory Liquidity Ratio).

Understanding this balance is crucial for Class 12 students preparing for exams and for grasping real-world economics.

Worked Example: Calculating Money Creation

Example:

Suppose the Reserve Bank of India sets the reserve ratio at 20%. A customer deposits ₹5,000 in a commercial bank. Calculate the maximum amount of money that can be created by the banking system.

Solution:

Given:

• Reserve Ratio (RR) = 20% = 0.20
• Initial Deposit (D) = ₹5,000

Using the formula:

$$\text{Maximum Money Created} = \frac{1}{RR} \times D = \frac{1}{0.20} \times 5000 = 5 \times 5000 = ₹25,000$$

So, the banking system can create up to ₹25,000 from an initial ₹5,000 deposit.

Note: This includes the initial deposit plus the money created through lending.

This example helps Class 12 students understand how reserve ratios influence money creation.
