Banking & RBI — Deep Dive

Before you start: [Financial Accounting](/academies/finance/accounting-basics/overview) basics are assumed. (Note: rates, ratios, and salary figures below reflect commonly cited reference points — RBI rates, Basel norms, and pay scales are revised periodically; verify current figures before relying on them.)

Why This Exists (The Hook)

A single failed bank doesn't just hurt its own shareholders — it can trigger a run on other banks, freeze credit across the economy, and destroy public confidence in the entire financial system, which is exactly what happened repeatedly before central banking existed in its modern form. RBI's structure and tools — the repo rate, CRR/SLR reserve requirements, Basel III capital adequacy rules, NPA classification — all exist to prevent that cascade: making sure banks hold enough safe reserves and capital that one institution's trouble doesn't become everyone's crisis, while still controlling the money supply precisely enough to manage inflation.

Analogy — Think of RBI's monetary policy tools like a thermostat controlling a building's temperature, not a light switch. A light switch is binary — on or off. A thermostat makes continuous small adjustments (raise or lower the target by a fraction of a degree) to keep the room in a comfortable range despite constantly changing outside conditions. The repo rate works the same way: small, deliberate adjustments (often just 0.25% at a time) that ripple through bank lending rates, borrowing costs, and ultimately spending and investment — the "transmission mechanism" is the thermostat's effect flowing through the whole building, not a single room.

Try it (2 minutes) — Reason through why the transmission mechanism (RBI ↓ Repo rate → Banks ↓ MCLR → Banks ↓ Lending rates → borrowing ↑ → GDP ↑) takes multiple steps to actually affect economic growth, rather than working instantly, without looking anything up: the repo rate is the rate RBI charges BANKS, not the rate banks charge their customers — that's a separate step (MCLR, then actual lending rates) that depends on banks choosing to pass the change along. If a bank decided NOT to lower its own lending rates even after RBI cut the repo rate, what would happen to the chain of consequences (more borrowing → more investment → GDP growth) that the whole mechanism depends on — and why does that make monetary policy's real-world effectiveness partly dependent on how banks actually respond, not just on what RBI sets?

RBI — Functions & Monetary Policy

Key Functions of RBI

1.Monetary authority: Controls money supply, inflation through monetary policy

2.Issuer of currency: Sole authority to issue notes (except ₹1 coin issued by Ministry of Finance)

3.Banker to government: Manages govt accounts, sells govt securities

4.Banker to banks: Maintains CRR, provides emergency liquidity (LOLR)

5.Regulator: Licenses banks, NBFCs, regulates foreign exchange (FEMA)

6.Manager of foreign exchange: Maintains forex reserves, manages INR

Monetary Policy Committee (MPC)

•6-member committee (3 RBI + 3 external, appointed by government)

•Meets every 2 months

•Targets: CPI inflation 4% (±2% band)

•Key rates:

Rate	Description	Current trend

|------|-------------|---------------|

Repo rate	Rate at which RBI lends to banks (overnight)	RBI's primary tool
Reverse repo	Rate at which RBI borrows from banks	= Repo - 25 bps typically
SLR	Statutory Liquidity Ratio — % of NDTL in liquid assets	~18%
CRR	Cash Reserve Ratio — % of NDTL as cash with RBI	~4%
MSF	Marginal Standing Facility — emergency overnight	= Repo + 25 bps
Bank Rate	Rate for rediscounting bills — long term	= MSF rate

Transmission mechanism: RBI ↓ Repo rate → Banks ↓ MCLR → Banks ↓ Lending rates → Corporates/consumers borrow more → Investment and consumption ↑ → GDP ↑

Banking Regulation — Key Provisions

Capital Adequacy — Basel III (RBI guidelines)

Credit Analysis — How Banks Evaluate Loans

Character

Track record, reputation -- CIBIL score 750+ preferred

Capacity

Ability to repay -- DSCR ≥ 1.25x

Capital

Borrower's own stake -- typically 25-30% margin

Collateral

Security offered -- hypothecation of assets

5 Cs of Credit:

1.Character: Borrower's track record, reputation (CIBIL score 750+ preferred)

2.Capacity: Ability to repay — DSCR (Debt Service Coverage Ratio) ≥ 1.25x

3.Capital: Borrower's own stake in the project — typically 25–30% margin

4.Collateral: Security offered — primary (hypothecation of assets) + collateral

5.Conditions: Economic environment, industry health, purpose of loan

Key financial ratios banks check:

•DSCR = Net Operating Income / Total Debt Service ≥ 1.25x

•Current Ratio = Current Assets / Current Liabilities ≥ 1.33x

•Debt-Equity Ratio ≤ 2:1 (project finance) or 3:1 (working capital)

•Net Profit Margin, EBITDA margin trends

NPA Management

NPA (Non-Performing Asset): Loan where interest/principal overdue > 90 days

Classification:

•Sub-standard: NPA for up to 12 months

•Doubtful: Sub-standard for more than 12 months (Doubtful 1/2/3)

•Loss assets: NPA written off or unrecoverable

Provisioning requirements:

Category	Provisioning %

|----------|---------------|

Standard	0.25–1%
Sub-standard	15%

Doubtful — unsecured	100%
Loss	100%

Recovery mechanisms:

•SARFAESI Act 2002: Banks can take possession and sell mortgaged assets without court order (commercial loans > ₹1 lakh, secured)

•DRT (Debt Recovery Tribunal): For loans > ₹20 lakh
