Money, Banking and Monetary Policy
Overview
This topic directly connects to current affairs as RBI policy decisions make regular headlines, and questions often test the practical application of monetary concepts rather than mere definitions.
Understanding this topic requires grasping the RBI's dual role as the monetary authority and banking regulator. Students must comprehend how policy rate changes ripple through the economy affecting inflation, growth, and employment. The interconnection between monetary policy tools, banking sector health (NPAs), and financial inclusion initiatives makes this a high-yield area where conceptual clarity pays dividends across multiple questions.
Mastery here also aids understanding of fiscal policy coordination, external sector management, and government borrowing programmes—topics that frequently appear in UPSC questions framed around Union Budget or economic survey data.
Key Concepts
- RBI as Monetary Authority: RBI controls money supply and credit conditions to maintain price stability (primary objective), support growth, and ensure financial stability. It acts as banker to government, banker's bank, and lender of last resort.
- Monetary Policy Committee (MPC): A 6-member statutory body (3 RBI + 3 government nominees) that decides policy rates. Decisions require majority vote; RBI Governor has casting vote in case of tie. Targets CPI inflation at 4% (±2%).
- Quantitative vs Qualitative Tools: Quantitative tools (CRR, SLR, repo rate) affect overall money supply uniformly; qualitative tools (margin requirements, moral suasion, selective credit control) target specific sectors.
- Transmission Mechanism: Policy rate changes → bank lending rates → investment and consumption → aggregate demand → inflation/growth. Transmission in India remains incomplete due to factors like MCLR rigidity and banking sector stress.
- Non-Performing Assets (NPAs): Loans where principal or interest remains overdue for more than 90 days. High NPAs constrain bank lending capacity and weaken monetary transmission.
- Financial Inclusion: Ensuring access to affordable financial services (savings, credit, insurance, pensions) for all sections, especially the unbanked poor. JAM trinity (Jan Dhan-Aadhaar-Mobile) is the backbone.
- Liquidity Adjustment Facility (LAF): The corridor within which overnight money market rates fluctuate—repo rate is the ceiling for borrowing, reverse repo (now SDF) is the floor for parking funds with RBI.
Formulas / Key Facts
| Tool | Current Rate (approx.) | Function |
|---|---|---|
| Repo Rate | 6.50% | Rate at which RBI lends to banks (short-term) |
| Standing Deposit Facility (SDF) | 6.25% | Floor rate; replaced reverse repo as primary absorption tool |
| Marginal Standing Facility (MSF) | 6.75% | Emergency borrowing window; 0.25% above repo |
| Bank Rate | 6.75% | Long-term lending rate; pegged to MSF |
| CRR | 4.5% | Cash reserves banks keep with RBI; no interest paid |
| SLR | 18% | Liquid assets (mainly G-secs) banks must hold |
Key numerical facts:
- MPC meets at least 4 times a year (bi-monthly)
- Inflation target: 4% CPI with upper tolerance of 6% and lower of 2%
- Priority Sector Lending target: 40% of ANBC for domestic banks
- PMJDY accounts: Over 52 crore (as of 2024)
- Gross NPA of SCBs: Declined from peak of 11.2% (2018) to around 3% (2024)
Worked Examples
Example 1: Effect of CRR Increase
Question: RBI increases CRR from 4% to 4.5%. How does this affect money supply?
Solution:
- Banks must now keep more cash with RBI (non-interest bearing)
- Lendable resources decrease
- Money multiplier falls (Money Multiplier = 1/CRR approximately)
- Credit creation capacity reduces → Money supply contracts
- This is a contractionary measure used to combat inflation
Example 2: Repo Rate Transmission
Question: RBI cuts repo rate by 50 basis points. Trace the expected transmission.
Solution:
- Banks' cost of borrowing from RBI falls
- Banks reduce MCLR/external benchmark lending rates
- Loans become cheaper → increased borrowing by firms and households
- Investment and consumption rise
- Aggregate demand increases → supports economic growth
- If sustained, may lead to demand-pull inflation (hence RBI balances carefully)
Example 3: NPA Classification
Question: A loan instalment was due on January 1. By what date does it become NPA?
Solution:
- NPA = overdue for more than 90 days
- Due date: January 1
- Becomes NPA: After April 1 (90 days later)
- Classification: First as Sub-standard (up to 12 months), then Doubtful, then Loss asset
Common Mistakes
- Confusing repo and reverse repo direction → Repo is RBI lending TO banks (injects liquidity); reverse repo/SDF is RBI absorbing FROM banks (absorbs liquidity).
- Thinking CRR earns interest → CRR deposits with RBI earn zero interest, unlike SLR assets (G-secs) which earn returns. This distinction matters for understanding why CRR changes hurt bank profitability.
- Assuming MPC controls all monetary tools → MPC decides only the policy repo rate. CRR, SLR, and other liquidity measures are decided by RBI independently.
- Equating inflation targeting with zero inflation → RBI targets 4% inflation, not zero. Some inflation is considered healthy for growth; deflation is equally problematic.
- Believing all NPAs are frauds → NPAs arise from business failures, economic downturns, wilful default, or fraud. Most NPAs result from genuine business stress rather than criminal intent.
- Mixing up scheduled banks and commercial banks → Scheduled banks are those in RBI's Second Schedule (includes commercial banks, RRBs, cooperative banks meeting criteria). Not all banks are scheduled.
Quick Reference
- MPC = 6 members, targets 4% CPI inflation, meets bi-monthly
- Repo rate increase = contractionary; decrease = expansionary
- CRR affects liquidity directly; SLR ensures solvency and G-sec demand
- NPA = overdue > 90 days; classified as Sub-standard → Doubtful → Loss
- PMJDY: Zero-balance accounts + RuPay card + overdraft facility + insurance
- SDF replaced reverse repo (2022) as floor of LAF corridor
