Money Creation By Banking System

Money creation by the banking system is the process by which banks generate new money in the economy through lending activities. Unlike common perception, banks don't simply lend out deposited money they actually create new money when they extend loans. This occurs through the fractional reserve banking system, where banks hold only a portion of deposits as reserves and lend out the remainder, effectively creating new purchasing power in the economy.

Formula

The money creation process is governed by the money multiplier formula:

$$\mathrm{Money\ Multiplier = \frac{1}{Reserve\ Ratio}}$$

Total money created in the banking system:

$$\mathrm{Total\ Money\ Supply = Initial\ Deposit \times Money\ Multiplier}$$

Variables:

• Reserve Ratio Fraction of deposits banks must hold as reserves
• Initial Deposit Original amount deposited into the banking system
• Money Multiplier Factor by which initial deposits are multiplied to create total money supply

Example Calculation

Let's calculate money creation when Bank X receives an initial deposit of Rs 1,000 with a 10% reserve requirement:

Step 1: Calculate the money multiplier

$$\mathrm{Money\ Multiplier = \frac{1}{0.10} = 10}$$

Step 2: Calculate maximum potential money creation

$$\mathrm{Maximum\ Money\ Supply = Rs\ 1,000 \times 10 = Rs\ 10,000}$$

Step 3: Bank X's lending activity

• Reserves kept: Rs 1,000 × 0.10 = Rs 100
• Amount lent: Rs 1,000 × 0.90 = Rs 900
• New money created: Rs 900

This Rs 900 loan becomes a deposit in another bank, continuing the money creation cycle.

Understanding Money Creation

Money creation occurs through two distinct banking systems:

100% Reserve Banking: Banks hold all deposits as reserves and don't lend money. In this system, if Bank X holds Rs 1,000 in deposits, it keeps the entire amount in reserves. No new money is created as the total money supply remains Rs 1,000.

Fractional Reserve Banking: Banks hold only a fraction of deposits as reserves and lend the remainder. This is the prevalent system globally. When Bank X receives Rs 1,000 in deposits with a 10% reserve requirement, it keeps Rs 100 as reserves and lends Rs 900, creating Rs 900 of new money.

100% Reserve Banking		Fractional Reserve Banking
Assets	Liabilities	Assets	Liabilities
Reserves Rs 1,000	Deposits Rs 1,000	Reserves Rs 100 Loans Rs 900	Deposits Rs 1,000

Factors Affecting Money Creation

• Reserve Requirement Higher reserve ratios reduce money creation capacity
• Loan Demand Strong demand encourages banks to lend more, creating more money
• Interest Rates Lower rates stimulate borrowing and money creation
• Economic Conditions Banks become more cautious during recessions, reducing lending
• Central Bank Policy Monetary policies directly influence bank reserves and lending capacity

Real-World Applications

Central Bank Policy: Central banks like the Reserve Bank of India use reserve requirements to control money supply and inflation. During economic slowdowns, they may reduce reserve ratios to encourage lending.

Commercial Banking: Banks earn profits by lending at higher interest rates than they pay on deposits. The money multiplier effect amplifies their lending capacity beyond actual deposits.

Economic Stimulus: Governments coordinate with central banks to inject money into the economy through the banking system, allowing the multiplier effect to amplify the stimulus impact.

Conclusion

Money creation by banks is a fundamental mechanism that expands the money supply beyond physical currency through fractional reserve banking. Understanding this process is crucial for comprehending how monetary policy affects economic growth and inflation.

FAQs

Q1. How many types of banking systems are there?

There are two types of banking systems: 100 percent reserve banking and fractional reserve banking system.

Q2. Are loans offered to the public in a 100 percent reserve banking system?

No. In 100 percent reserve banking, banks only keep the deposited money of the public safe and do not extend any loans.

Q3. Which system of banking is commonly used in modern economies?

Fractional reserve banking is the common banking process used in modern economies worldwide.

Q4. Does money creation by banks increase inflation?

Yes, excessive money creation can lead to inflation if the money supply grows faster than economic output, as more money chases the same goods and services.

Q5. How do central banks control money creation?

Central banks control money creation through reserve requirements, discount rates, and open market operations that influence bank lending capacity.
