1. Basics of Commercial Banking and Asset Creation (basic)
At its heart, a commercial bank is a financial intermediary that acts as a bridge between people who have extra money (savers) and those who need it for investment or consumption (borrowers). Unlike a simple vault, a bank is a money-creating institution. It takes deposits from the public and lends a significant portion of those funds out to earn a profit Macroeconomics (NCERT class XII 2025 ed.), Money and Banking, p.38.
To understand how a bank operates, we must look at its Balance Sheet. In accounting, a balance sheet must always balance: Total Assets must equal Total Liabilities. For a bank, these terms have very specific meanings:
- Liabilities: These are things the bank owes to others. The most common examples are the deposits you make into your savings or current accounts. Since the bank must return this money to you upon request, it is a liability for them Indian Economy, Vivek Singh (7th ed. 2023-24), Money and Banking- Part I, p.55.
- Assets: These are things the bank owns or has a claim on. Interestingly, the loan the bank gives you is its asset. Why? Because that loan represents a legal claim the bank has to receive money (with interest) from you in the future. Other assets include the bank's physical buildings and the reserves it keeps Macroeconomics (NCERT class XII 2025 ed.), Money and Banking, p.39.

The primary way a bank makes a profit is through the 'Spread'. The bank pays a lower interest rate to you (the depositor) and charges a much higher interest rate to the borrower. The difference between these two rates is the bank's earnings Macroeconomics (NCERT class XII 2025 ed.), Money and Banking, p.38. However, banks cannot lend out every rupee they receive. The Central Bank (RBI) mandates that banks keep a certain percentage of deposits as reserves to ensure they can meet withdrawal demands, which limits their power to create infinite credit Macroeconomics (NCERT class XII 2025 ed.), Money and Banking, p.40.
Key Takeaway For a commercial bank, a loan is an asset because it is a future claim on income, while a deposit is a liability because it is money the bank eventually owes back to the public.

2. Interest Rate Mechanisms (Fixed vs. Floating) (basic)
When you take a loan or invest in a bond, the interest rate is essentially the "price" of that money. This price can be structured in two primary ways: Fixed or Floating. A Fixed Rate remains constant throughout the tenure of the loan or bond, providing certainty to both the borrower and the lender. For instance, many corporate debentures offer a fixed rate of interest that is typically higher than standard Fixed Deposits (FDs) to attract investors, though this rate is often influenced by the credit rating of the issuer—lower-rated entities must pay higher interest to compensate for the higher risk Indian Economy, Nitin Singhania (2nd ed.), Agriculture, p.263. Similarly, Fixed Rate Bonds maintain the same coupon rate until maturity Indian Economy, Vivek Singh (7th ed.), Money and Banking- Part I, p.46.
In contrast, Floating Rates (also known as variable rates) fluctuate over time based on a reference point called a benchmark. In India, banks previously used "internal benchmarks" like the Marginal Cost of Funds Based Lending Rate (MCLR). However, because MCLR is calculated based on a bank’s own internal costs, banks were often slow to reduce lending rates even when the RBI cut the repo rate. To fix this lag in monetary policy transmission, the RBI mandated that all new floating-rate retail and MSME loans be linked to External Benchmarks (like the Repo Rate or Treasury Bill yields) starting October 1, 2019 Indian Economy, Vivek Singh (7th ed.), Money and Banking- Part I, p.91. This ensures that when the central bank changes policy rates, the benefit (or cost) reaches the consumer much faster.
One specific and often controversial version of these mechanisms is the Teaser Loan. These start with an artificially low fixed interest rate for the initial years to attract borrowers (often those with lower credit scores), but then "reset" to a much higher floating rate later. While they can stimulate demand, they carry a high risk of default if the borrower’s income doesn't rise sufficiently to meet the higher future payments. It is also important to note that even with floating rates, changes aren't always instantaneous; they occur at specific reset dates defined in the loan agreement Indian Economy, Vivek Singh (7th ed.), Money and Banking- Part I, p.92.

Key Takeaway Fixed rates provide payment certainty, while floating rates linked to external benchmarks ensure that changes in RBI's policy rates are transparently and quickly passed on to the borrower.

3. Asset Quality and Non-Performing Assets (NPAs) (intermediate)
To master banking operations, we must first look at the balance sheet through the bank's eyes. While your savings account is an 'asset' to you, it is a 'liability' to the bank because they owe it back to you. Conversely, the loans the bank gives out are its
Assets, because they generate income through interest.
Asset Quality is simply a measure of how likely these loans are to be paid back. When a borrower fails to pay interest or principal for a period of
more than 90 days, the loan is classified as a
Non-Performing Asset (NPA) Indian Economy, Vivek Singh (7th ed. 2023-24), Money and Banking - Part II, p.135.
The RBI requires banks to categorize these NPAs based on their 'age' and the likelihood of recovery. This transparency ensures that the bank's financial health is accurately reported. The categories are as follows
Indian Economy, Nitin Singhania (2nd ed. 2021-22), Financial Market, p.228:
| Category | Criteria/Duration | Description |
|---|
| Sub-standard | ≤ 12 months | Assets which have remained NPAs for a period less than or equal to 12 months. |
| Doubtful | > 12 months | Assets which have remained in the sub-standard category for more than 12 months. |
| Loss Assets | No limit | Identified as uncollectible by the bank or RBI, but not yet fully written off. |
Beyond NPAs, we often hear the term
Stressed Assets. This is a broader category that includes NPAs plus
Restructured Loans (where the bank gives the borrower more time or lower rates to prevent default) and
Written-off Assets Indian Economy, Vivek Singh (7th ed. 2023-24), Money and Banking - Part II, p.135. To prepare for these losses, banks must follow
Provisioning norms. This involves setting aside a portion of their profits (a 'buffer') to cover potential losses. The
Provisioning Coverage Ratio (PCR) tells us how much of the total NPAs are covered by these set-aside funds
Indian Economy, Nitin Singhania (2nd ed. 2021-22), Financial Market, p.232.
An interesting specific risk to asset quality is the
Teaser Loan. These loans lure borrowers with an initially very low interest rate that 'jumps' significantly after a few years. While they stimulate demand (as seen with home loans in India), they carry a high risk of becoming NPAs if the borrower's income does not grow enough to match the higher future payments
Indian Economy, Nitin Singhania (2nd ed. 2021-22), Money and Banking, p.183.
Key Takeaway Asset quality is the pulse of a bank; a loan becomes an NPA after 90 days of non-payment, requiring the bank to set aside 'provisions' to protect its financial stability.

4. Sub-prime Lending and Global Financial Crisis (intermediate)
In the world of banking, borrowers are generally classified based on their creditworthiness. Prime lending is extended to borrowers with high credit scores and stable incomes, posing minimal risk to the bank. Conversely, Sub-prime lending refers to loans provided to individuals who do not qualify for conventional market rates due to poor credit history or unstable financial backgrounds. To attract these high-risk borrowers, banks often employ Teaser Loans—a specific sub-prime product where the interest rate is kept artificially low for the initial few years (the 'teaser' period) before 'resetting' to a significantly higher rate later. While these help stimulate demand in the housing sector, they carry a high risk of default if the borrower’s income doesn't rise or if property values stagnate before the rates reset Indian Economy, Nitin Singhania, Chapter 7, p.183.
The 2008 Global Financial Crisis (GFC) was largely rooted in the collapse of the US sub-prime mortgage market. Banks aggressively lent to sub-prime borrowers, bundled these loans into complex financial products, and sold them globally. When the teaser periods ended and interest rates rose, millions of borrowers defaulted, leading to a systemic collapse. For a borrower, a high-cost loan means a larger portion of their earnings goes toward repayment, often leaving them with insufficient income for basic needs, a phenomenon often observed in informal lending markets as well Understanding Economic Development, Class X NCERT, MONEY AND CREDIT, p.48.

India’s banking system remained relatively immune to the 2008 crisis because of its conservative approach. For instance, the Reserve Bank of India (RBI) maintains strict oversight on short-term foreign borrowings and capital account convertibility to prevent sudden capital flight during global shocks Indian Economy, Vivek Singh, Money and Banking- Part I, p.120. While Indian banks like SBI did introduce teaser loans to boost home sales, they were regulated more tightly than the sub-prime products in the West. It is important to distinguish these from schemes like MUDRA, which are designed to support micro-entrepreneurs through structured credit rather than teaser rate traps Indian Economy, Nitin Singhania, Chapter 7, p.183.
Key Takeaway Sub-prime lending targets high-risk borrowers using teaser rates that start low but reset significantly higher, creating a systemic risk of mass defaults if economic conditions worsen.

5. Schemes for Entrepreneurs and MSMEs (exam-level)
To understand how the Indian banking system supports growth, we must look at how it bridges the credit gap for small businesses. Because
Micro, Small, and Medium Enterprises (MSMEs) are employment-intensive but often lack traditional collateral, the RBI uses
Priority Sector Lending (PSL) mandates. Under these rules, Scheduled Commercial Banks must direct 40% of their Adjusted Net Bank Credit (ANBC) to priority sectors, while Regional Rural Banks (RRBs) and Small Finance Banks (SFBs) have a much higher target of 75%
Nitin Singhania, Financial Market, p.241. In 2020, this net was widened to include the
Startup sector, ensuring that innovation-led entrepreneurship also receives formal credit support
Nitin Singhania, Financial Market, p.241.
One of the most vital instruments for financial inclusion is the Pradhan Mantri MUDRA Yojana (PMMY). Its primary goal is to bring small, often informal entrepreneurs into the formal financial fold Vivek Singh, Money and Banking- Part I, p.118. Rather than offering unpredictable interest structures like teaser loans—which are common in the housing sector but risky due to sharp interest resets—MUDRA provides structured credit based on the business's growth stage. These loans are disbursed by commercial banks, RRBs, and Microfinance Institutions (MFIs), with MUDRA Ltd. providing refinance support to these lenders to ensure liquidity Nitin Singhania, Money and Banking, p.183.
The MUDRA scheme is categorized into three distinct products tailored to the 'enterprise spectrum':
| Category |
Loan Amount Range |
Target Beneficiary |
| Shishu |
Up to ₹50,000 |
Start-ups or units in the initial stage |
| Kishore |
₹50,001 to ₹5 Lakh |
Units needing capital for expansion |
| Tarun |
₹5 Lakh to ₹10 Lakh |
Established units requiring higher credit |
Vivek Singh, Money and Banking- Part I, p.84
Beyond direct lending, the system uses Priority Sector Lending Certificates (PSLCs). If a bank exceeds its MSME lending target, it can sell these certificates to banks that have a shortfall. This market-driven mechanism incentivizes banks to lend more to small entrepreneurs while allowing the banking system as a whole to meet national development goals Nitin Singhania, Financial Market, p.241.
Key Takeaway MSME financing in India is driven by mandatory Priority Sector Lending (PSL) targets and the tiered MUDRA scheme (Shishu, Kishore, Tarun) to ensure credit reaches the "bottom of the pyramid" entrepreneurs.

6. Teaser Loans: Concept and Regulatory Concerns (exam-level)
Imagine walking into a bank and being offered a home loan where you pay an incredibly low interest rate for the first two years. This 'hook' is what we call a
Teaser Loan. Conceptually, it is a loan that starts with a very low, fixed interest rate (the 'teaser') for an initial period, which then 'resets' to a significantly higher floating rate for the remainder of the loan term. While banks naturally act as mediators by lending out the deposits they receive to meet the credit needs of the public
Understanding Economic Development. Class X . NCERT(Revised ed 2025), MONEY AND CREDIT, p.41, teaser loans are a specific marketing strategy used to stimulate demand by making loans look more affordable in the short term.
The regulatory concern arises because teaser loans are often a gateway to
sub-prime lending. They tend to attract borrowers who might not qualify for conventional prime mortgages or those who are betting on a future income increase that may never happen. When the teaser period ends, the borrower faces a
'payment shock'—a sudden, sharp increase in their Monthly Installments (EMIs). If the borrower’s income hasn't grown or if property values have declined, the risk of default spikes. To prevent such systemic risks, the
Reserve Bank of India (RBI) monitors these interest rate structures closely, ensuring that banks do not compromise on credit standards or collateral requirements

In India, teaser loans were primarily used in the
home loan segment by commercial banks to boost the housing market. It is vital to distinguish these from government-backed schemes like
MUDRA, which target micro-entrepreneurs and do not typically follow this aggressive teaser structure. Because bank loans generally require proper documentation and collateral
Understanding Economic Development. Class X . NCERT(Revised ed 2025), MONEY AND CREDIT, p.49, the RBI remains cautious that 'teaser' lures do not lead to a dilution of these essential safety checks.
Key Takeaway Teaser loans offer low initial rates to attract borrowers, but they pose a significant regulatory risk of default when interest rates 'reset' to higher levels, potentially leading to Non-Performing Assets (NPAs).

7. Solving the Original PYQ (exam-level)
This question perfectly synthesizes your recent study of credit market dynamics and banking risks. By connecting the concept of Teaser Loans—which you know are loans featuring an artificially low initial interest rate that later "steps up"—to the broader category of sub-prime lending, you can see the structural vulnerability they create. Statement 1 is correct because these loans often target borrowers with lower creditworthiness; the "economic concern" arises from the systemic risk of default when the teaser period ends and repayment obligations suddenly spike, a phenomenon that was a primary catalyst for the 2008 Global Financial Crisis as noted in The Origins of the Financial Crisis (Brookings).
To navigate the second statement, you must apply your knowledge of the Indian banking landscape. While it is true that India incentivizes MSMEs and export units, it does so through targeted schemes like MUDRA or priority sector lending, rather than high-risk teaser structures. In the Indian context, teaser loans were primarily a marketing strategy in the home loan (retail) segment, famously used by commercial banks like SBI to stimulate housing demand. Since Statement 2 incorrectly identifies the target demographic as "inexperienced entrepreneurs" in manufacturing, it acts as a plausible-sounding distractor that you must discard based on factual application.
The reasoning process here involves first identifying the inherent risk of the financial product (Statement 1) and then verifying its specific historical application in India (Statement 2). UPSC often uses this "General Principle vs. Specific Fact" trap to test if students can distinguish between a product's definition and its actual use-case. By recognizing that teaser loans are a retail mortgage tool rather than an industrial development tool, you can confidently arrive at the correct answer (A) 1 only, as corroborated by Indian Economy by Nitin Singhania.
