Section 01
What is the RBI — and Why Does It Exist?
The Reserve Bank of India is the central bank — the "banker of all banks" and custodian of the entire country's money supply. It was established on April 1, 1935 under the Reserve Bank of India Act, 1934.
"To regulate the issue of bank notes and keeping of reserves with a view to securing monetary stability in India and generally to operate the currency and credit system of the country to its advantage."
— RBI's official mandate
🏛️
Banker to the Government
RBI manages India's government accounts, issues government bonds (G-Secs), and manages the national debt. When the government needs money, it borrows through RBI.
🏦
Banker to Banks
All commercial banks (SBI, HDFC, ICICI etc.) maintain accounts with RBI. When banks run short of funds, they borrow from RBI. This is the "lender of last resort" role.
💵
Currency Issuer
Only the RBI can print and issue ₹10, ₹20, ₹50, ₹100, ₹200, ₹500 and ₹2000 notes. (₹1 coins are issued by the Government of India.)
📊
Inflation Controller
Since 2016, RBI has a legal mandate to keep inflation between 2% and 6%, with a target of 4%. The Monetary Policy Committee (MPC) meets every 2 months to review this.
💱
Foreign Exchange Manager
RBI manages India's foreign exchange reserves (currently over $600 billion) and intervenes in currency markets to prevent excessive rupee volatility.
🔍
Banking Regulator
RBI sets rules for how banks operate — minimum capital requirements, loan classification norms, interest rate guidelines, and consumer protection rules.
💡 KEY FACT
The RBI is independent of the government in operational decisions — especially monetary policy. This independence is essential: a government facing elections would always want lower interest rates and more money printing, regardless of inflation. The RBI resists this pressure to protect long-term stability.
Section 02
Borrowing Tools — How RBI Controls Interest Rates
The RBI's primary toolkit. By changing what it costs banks to borrow, RBI can make money cheaper or more expensive throughout the entire economy.
🔴
Repo Rate
The most powerful monetary policy tool
RATE AT WHICH RBI LENDS TO BANKS
"Repo" comes from "Repurchase Agreement." When a bank needs money urgently, it approaches RBI and gives government securities (bonds) as collateral. RBI gives cash, and the bank agrees to buy back those securities at a slightly higher price. The extra amount paid is effectively the interest — the repo rate.
CURRENT RATE (DEC 2025)5.25%
Simple example: SBI needs ₹1,000 Cr overnight. It gives RBI government bonds worth ₹1,000 Cr. RBI gives ₹1,000 Cr cash. Next morning, SBI gives back ₹1,000.14 Cr (₹14 lakh extra = 5.25% interest for 1 day). SBI gets its bonds back. This is a repo transaction.
💡 WHY IT MATTERS TO YOU
When repo rate rises → banks pay more to borrow → they charge you more on home loans, car loans, business loans. When repo rate falls → borrowing gets cheaper → your EMI can go down.
🔵
Reverse Repo Rate
RBI borrows from banks
RATE RBI PAYS TO BORROW FROM BANKS
The exact opposite of repo rate. When banks have too much excess cash that they don't know what to do with, they park it with RBI. RBI borrows this money and pays interest at the reverse repo rate. This is how RBI "sucks out" excess liquidity from the banking system.
CURRENT RATE3.35%
Simple example: After a good quarter, HDFC Bank has ₹500 Cr sitting idle. Lending it in the market seems risky. So it deposits ₹500 Cr with RBI overnight. RBI gives 3.35% interest. HDFC earns safe returns, and excess money is removed from circulation. Inflation stays under control.
💡 THE CORRIDOR
Repo rate (5.25%) is the ceiling — banks won't lend to each other above this since they can always borrow from RBI at 5.25%. Reverse repo (3.35%) is the floor — banks won't lend below this since they can always park at RBI. All interbank lending happens between these two rates.
🆘
MSF — Marginal Standing Facility
Emergency overnight borrowing
EMERGENCY BORROWING ABOVE REPO
The MSF is an emergency window for banks. When normal borrowing limits are exhausted and a bank still needs funds, it can borrow from the MSF — but at a higher penalty rate (repo + 0.25%). It was introduced in 2011 to provide a safety valve for extreme liquidity crunches.
CURRENT RATE5.50%
Key feature: Under MSF, banks can use securities from their SLR requirement as collateral (up to 2% of deposits). This means in an emergency, a bank can unlock its "mandatory reserves" to borrow — something not allowed under normal repo.
🟢
SDF — Standing Deposit Facility
Replaced reverse repo as floor rate
FLOOR OF INTEREST RATE CORRIDOR
Introduced in 2022, the SDF allows banks to park excess money with RBI without providing collateral (unlike reverse repo). This makes it more flexible. The SDF rate (5.00%) is now the effective floor of the interest rate corridor, replacing the old reverse repo role.
CURRENT RATE5.00%
Corridor today: SDF (5.00%) → Repo (5.25%) → MSF (5.50%). The repo sits in the middle. Banks borrow above it (MSF) when desperate, and deposit below it (SDF) when they have surplus funds.
📐 Bank Rate — Long-term Lending
CURRENTLY = MSF RATE = 5.50%
The bank rate is the rate at which RBI provides long-term loans to commercial banks, without collateral. Unlike the repo rate (which is short-term, overnight, against securities), the bank rate covers long-duration lending. In practice, RBI rarely uses the bank rate today — it has been aligned with the MSF rate and mainly serves as the penalty rate for banks that fail to maintain CRR or SLR requirements.
📞 Call Rate — Interbank Lending
FLOATS DAILY · MARKET DETERMINED
The call rate is what banks charge each other for very short-term loans (overnight to a few days) in the inter-bank market. It is not set by RBI directly — it is determined by supply and demand. But it stays within the corridor set by SDF (floor) and MSF (ceiling). When there's excess liquidity, the call rate falls toward SDF. When liquidity is tight, it rises toward MSF.

⏱️ TRANSMISSION LAG
Rate cuts don't work instantly. Banks take 2–6 months to pass on cuts to customers. EBLR-linked loans (External Benchmark Lending Rate — mandated from Oct 2019) transmit changes within 3 months. MCLR-linked older loans can take up to a year. This lag is why RBI often needs several consecutive cuts to see full economic effect.
Section 03
Open Market Operations — How RBI Buys and Sells
Beyond interest rates, RBI directly controls how much money exists in the system by buying and selling government bonds in the open market.
Open Market Operations (OMO)
RBI buys or sells Government of India securities (bonds) directly in the financial markets
RBI BUYS BONDS (OMO PURCHASE)
RBI pays cash to buy G-Secs from banks and financial institutions. This cash enters the banking system — increasing liquidity. Banks now have more money to lend.
↑ Money supply ↑ Liquidity ↓ Bond yields (prices rise)
RBI SELLS BONDS (OMO SALE)
RBI sells G-Secs to banks, which pay cash. This cash leaves the banking system — reducing liquidity. Banks have less money. Credit tightens. Useful for controlling inflation.
↓ Money supply ↓ Liquidity ↑ Bond yields (prices fall)
G-SAP (SPECIAL VERSION)
Government Securities Acquisition Programme. Used during COVID in 2021. RBI committed to buy bonds worth ₹1 lakh crore per quarter — a pre-announced OMO schedule to give markets certainty.
Used when markets panic and need forward guidance
WHY BONDS AND INTEREST RATES MOVE TOGETHER
When RBI buys bonds → demand rises → bond prices rise → bond yields fall (yield moves opposite to price). This is why repo rate cuts and OMO purchases both push bond yields lower.
Bond price ↑ = Bond yield ↓ (always inverse)
💱 Forex Swaps — Dollar-Rupee Tool
Used for both liquidity management and rupee stabilisation
A forex swap is when RBI buys USD from banks today (injecting rupees into the system) with an agreement to sell the same USD back on a future date (at a pre-agreed price). In December 2025, RBI announced a $5 billion forex swap to inject rupee liquidity while also managing dollar demand.
📌 RECENT EXAMPLE
Dec 2025: RBI announced ₹1 lakh crore in OMO bond purchases + $5 billion USD/INR forex swap to inject liquidity and speed up rate cut transmission to the economy.
📋 LAF — Liquidity Adjustment Facility
The daily toolkit for fine-tuning short-term liquidity
The LAF is the daily mechanism through which RBI adjusts liquidity. It includes both repo operations (lending to banks) and reverse repo/SDF operations (absorbing from banks). Banks approach RBI through LAF every morning with their liquidity needs or surplus.
Under LAF, RBI also conducts Variable Rate Repos (VRR) and Variable Rate Reverse Repos (VRRR) — auctions where the rate is determined by market demand rather than being fixed.
Section 04
Reserve Requirements — Money Banks Must Lock Away
These are RBI's structural tools — they determine how much of every rupee deposited in a bank can be lent out, and how much must be set aside.
🔒
CRR — Cash Reserve Ratio
Cash locked with RBI. Earns zero interest.
MANDATORY CASH WITH RBI
Every bank must keep a percentage of its total deposits as cash with the RBI. This money cannot be lent out. It earns zero interest. It exists purely to ensure banks always have enough cash to meet sudden withdrawal demands and gives RBI direct control over money supply.
CURRENT CRR3.00%
What this means: If SBI has ₹10 lakh crore in deposits, it must keep ₹30,000 crore locked with RBI as cash. This ₹30,000 crore is completely frozen — it earns nothing and cannot be used for lending. The remaining ₹9.7 lakh crore can potentially be lent.
🔧 HOW RBI USES CRR
CRR raised → banks have less to lend → credit contracts → inflation controlled. CRR cut (like the June 2025 cut from 4.00% to 3.00%) → banks can lend more → economy gets more money. A 0.50% CRR cut releases ~₹1.16 lakh crore. The June 2025 cut of 100 bps released over ₹2.3 lakh crore into the banking system.
📋
SLR — Statutory Liquidity Ratio
Government bonds/gold. Earns some interest.
MUST HOLD AS LIQUID ASSETS
Every bank must maintain a minimum percentage of its deposits as liquid assets — cash, gold, or government-approved securities (typically government bonds/G-Secs). Unlike CRR, banks earn interest on the government bonds held as SLR. SLR ensures banks invest in safe government debt and cannot lend excessively in risky assets.
CURRENT SLR18.00%
What this means: On ₹10 lakh crore deposits, a bank must hold ₹1.8 lakh crore in government bonds/gold/cash. It earns ~6–7% interest on these G-Secs. The remaining ₹8.2 lakh crore (minus CRR) is available for lending. SLR is why banks are forced to fund government borrowing.
📌 CRR vs SLR — KEY DIFFERENCE
CRR = Cash only, held with RBI, zero returns. SLR = Cash OR gold OR G-Secs, held by the bank itself, earns interest. CRR is more painful for banks because it earns nothing. SLR is the government's built-in mechanism to ensure demand for its own bonds.
How Deposits Flow Through the Reserve System
For every ₹100 deposited in any Indian bank, here is where the money goes:
₹3
CRR (3%)
Cash locked at RBI. Zero returns.
₹18
SLR (18%)
G-Secs/gold. Earns ~6%.
₹79
LENDABLE
Available for loans, investments.
₹100
TOTAL
Your deposit in the bank.
🔢 THE MONEY MULTIPLIER
Because banks only hold a fraction of deposits and lend the rest, one rupee deposited can become several rupees in the economy through repeated lending. This is the "money multiplier." If CRR+SLR = 21%, the multiplier is roughly 100/21 ≈ 4.8×. One ₹100 deposit eventually creates ~₹480 in total economic activity. This is why reducing CRR is powerful — even a 0.5% cut can release over ₹1 lakh crore into the economy.

How RBI Decisions Affect Your Money
A rate change at Mint Road Mumbai ripples through every loan, FD, stock market, and bank account in the country. Here is exactly how.
Rate Hike vs Rate Cut — Complete Impact Table
| What Changes | When Repo Rate RISES | When Repo Rate FALLS | How Quickly |
|---|
| Home Loan EMIs |
EMI increases ₹1 lakh loan @ 25 yr: ~₹60 higher per 0.25% hike |
EMI decreases Linked EBLR loans adjust in 1–3 months |
EBLR loans: 1–3 months. MCLR loans: 3–12 months. |
| Fixed Deposits (FD) |
FD rates rise Good time to lock in higher FD rates |
FD rates fall Consider longer tenure FDs before rates drop |
Banks typically adjust FD rates within 2–4 weeks of RBI decision |
| Stock Market |
Usually negative Higher borrowing costs → lower corporate profits → stocks fall |
Usually positive Cheaper credit → growth expectations rise → stocks rally |
Markets react same day, often in minutes of RBI announcement |
| Bond Prices/Yields |
Bond prices fall Yields rise. Existing bond holders lose value. |
Bond prices rise Yields fall. Good for debt mutual funds. |
Immediate — bond market reacts instantly |
| Rupee vs Dollar |
Rupee strengthens Higher rates attract foreign investors seeking yield |
Rupee may weaken Lower returns can reduce foreign investment appeal |
Immediate but not always — global factors often dominate |
| Real Estate |
Demand slows Higher EMIs make homes less affordable |
Demand improves Lower EMIs → more buyers → real estate activity picks up |
6–18 months lag — real estate is slow to react |
| Inflation |
Inflation cools Less money in economy → less demand → prices stabilise |
Inflation risk rises More money → more demand → potential price rise |
6–24 months — monetary policy impact on prices is very slow |
📌 MCLR vs EBLR — WHY IT MATTERS TO BORROWERS
MCLR (Marginal Cost of Funds based Lending Rate): Set internally by each bank based on their cost of funds. RBI's repo rate is one input. Reset every 6–12 months. Old loans taken before 2019 still use MCLR — these are slow to reflect rate changes.
EBLR (External Benchmark Lending Rate): Mandated by RBI from October 2019. Directly linked to repo rate (or T-bill rates). Resets every 3 months. All new home loans, auto loans, and MSME loans must use EBLR. These transmit RBI rate changes within one quarter — much faster than MCLR.

Complete RBI Role Reference
Everything the RBI does, explained clearly in one place.
🖨️
Currency Issue
Sole authority to print and issue currency notes (except ₹1 coin). Every note is a liability of RBI, backed by gold and foreign assets. RBI manages the entire note supply to prevent fake currency and ensure adequate cash circulation.
🏛️
Debt Manager for Govt
Issues government bonds (G-Secs, T-bills) on behalf of India's central and state governments. Manages the auction process and ensures the government can borrow at reasonable rates.

Banking Regulation
Licenses banks. Sets minimum capital (CRAR), loan provisioning norms, exposure limits, KYC rules. Conducts inspections. Can supersede bank boards, remove directors, or cancel licences for serious violations.
🌐
FEMA Administration
Administers the Foreign Exchange Management Act. Controls what can be done with foreign currency. Approves FDI, ECB (external borrowings), capital account transactions, and manages India's forex reserves (~$600 billion+).
💳
Payments System
Oversees all digital payments — UPI, RTGS, NEFT, IMPS, NACH. Regulates payment banks, prepaid wallets, card networks. Sets interoperability standards. Made India the world's largest real-time payments market.
🛡️
Consumer Protection
The RBI Ombudsman handles complaints against banks. Sets rules on ATM fees, minimum bank balances, interest rate transparency, and unfair charges. The "Integrated Ombudsman Scheme" provides free dispute resolution.
🌾
Priority Sector Lending
Mandates banks to lend 40% of their loans to priority sectors — agriculture, MSMEs, education, affordable housing, weaker sections. If a bank fails to meet this, it must invest in low-return RIDF bonds as penalty.
📡
Data & Statistics
Publishes comprehensive data — inflation, money supply, credit growth, banking sector health, balance of payments. The RBI Annual Report, Monetary Policy Report, and Financial Stability Report are key policy documents.
🚨
Lender of Last Resort
If a systemically important bank faces a severe liquidity crisis (runs, sudden deposit withdrawals), RBI provides emergency funding to prevent collapse. This power prevents bank runs from becoming full financial crises.
The Core RBI Framework — One Mental Model
💰
Too MUCH money
Inflation rising → RBI raises repo rate → borrowing expensive → less lending → money supply shrinks → inflation cools
⚖️
BALANCE
RBI's target: 4% inflation (within 2%–6% band) + strong GDP growth. This tension never fully resolves — it requires constant calibration.
📉
Too LITTLE money
Growth slowing → RBI cuts repo rate → borrowing cheaper → more lending → money supply grows → economy stimulated
📌 THE BOTTOM LINE
Every RBI action is ultimately about one thing: controlling how much money is in the economy. Too much money = inflation. Too little money = recession. The repo rate, CRR, SLR, OMO, and forex tools are all different ways to achieve the same goal — keeping the money supply growing at exactly the right pace to support development without triggering inflation.
