Step 1: Understanding the Concept:
Commercial banks are profit-oriented financial institutions that act as intermediaries between the "surplus units" (savers) and "deficit units" (borrowers) in an economy. They are the backbone of the modern financial system, facilitating the mobilization of small savings into large-scale investments. Their primary role is to provide liquidity to the market and enable the process of credit creation, which multiplies the initial money supply in the economy.
Step 2: Detailed Explanation:
The operations of a commercial bank can be broken down into two essential primary functions:
1. Accepting Deposits: This is how banks source their funds. They offer various accounts such as Savings Accounts (for individuals), Current Accounts (for businesses), and Fixed Deposits (for long-term savings). By offering safety and a small interest rate, they encourage the public to keep their money in the formal banking system rather than as idle cash at home.
2. Advancing Loans: This is how banks generate revenue. The deposits collected are not kept idle; a portion is kept as reserves (as per Central Bank regulations), and the rest is lent out to individuals for personal use (car loans, home loans) or to businesses for expansion and working capital. Banks charge a higher interest rate on these loans than what they pay to depositors.
3. Differentiating from the Central Bank: It is vital to distinguish these from Central Bank functions.
- Printing Currency (Option A): This is a "Monopoly of Note Issue" held only by the Central Bank (like the RBI in India). Commercial banks cannot print money.
- Monetary Policy (Option C): The Central Bank regulates the cost and availability of money using tools like the Repo Rate or Cash Reserve Ratio. Commercial banks must follow these policies but do not create them.
- Collecting Taxes (Option D): While governments use the banking network to collect taxes for convenience, this is a secondary administrative service, not the defining economic function of a commercial bank.
Step 3: Final Answer:
The fundamental business model of a commercial bank is built upon the dual activity of accepting public deposits and utilizing those funds to provide loans and advances.
