Passive investing in India has moved from a small niche to almost mainstream.

By January 2026, passive assets touched ₹15 lakh crore, which is about 19% of the entire mutual fund industry. This shows how quickly Indian investors especially retail SIP investors are adopting low cost, rules based products.

At the same time, the overall mutual fund industry grew ~21% in 2025, and passive funds (index funds + ETFs) were the fastest growing category.

This growth is being driven by:

• simpler products

• lower fees

• more transparency

• supportive regulations

• and the rising comfort of retail investors with long term SIPs

What Is Index & Passive Investing?

Index investing means buying the whole market (e.g., Nifty 50, Sensex) in the same weights as the index through index mutual funds or ETFs. You don’t try to beat the market; you aim to match it keeping fees low, decisions simple, and behaviour disciplined.

Index funds vs ETFs:

🔷 Index Funds (Mutual Funds version)

Think of this as the easiest way to invest in an index.

How they work:

• You buy them from a mutual fund platform or AMC.

• Your order gets executed at the day’s closing NAV not the moment you place it.

Why people prefer them:

• Best for SIP (automatic monthly investing)

• No Demat account needed

• No need to check price, volume, or spreads

• Extremely beginner friendly

Perfect for:

• Long term SIP investors

• Set and forget portfolios

• People who want simplicity, not daily monitoring

🟧 ETFs (Exchange Traded Funds)

These are index funds that behave like shares.

How they work:

• You buy and sell them on NSE/BSE, just like stocks.

• Prices move all day depending on supply–demand.

• You need a Demat + trading account.

What you must check:

• Daily trading volume

• Bid ask spread (difference between buy & sell prices)

Low volume ETFs can:

• Cost you slightly more when buying

• Pay you slightly less when selling

Perfect for:

• Investors who want intraday flexibility

• People comfortable with broker apps

• Those who understand liquidity and spreads

Quick Comparison:

Feature	Index Fund	ETF
How you buy	From MF house/platform	From NSE/BSE
Price	End of day NAV	Changes every minute
Demat required	❌ No	✔ Yes
Best for	SIP, long term, beginners	Active investors, intraday buyers
Liquidity issues	None	Sometimes (depends on volume)

Why Passive Is Rising in India (2024–2026)

1) More retail investors are choosing passives

A growing number of Indian investors now hold at least one index fund or ETF.

People like passive investing because it is:

• simple

• low cost

• less stressful

• easy to start (especially with SIPs)

2) The ETF market is growing very fast

ETF assets have multiplied, and:

• trading volumes are rising

• more retail folios are being opened

• liquidity is improving

That means buying and selling ETFs has become easier and smoother than before.

3) Strong regulatory support

SEBI has introduced and proposed several reforms like:

• TRI benchmarking (more accurate performance comparison)

• MF Lite framework (2024) for simpler passive products

• Oversight of major index providers

All this increases transparency, trust, and clarity, which benefits passive funds.

4) Lower tracking error is coming

A proposed Closing Auction Session (CAS) will help passive funds execute trades closer to the market’s official close.

This means:

• lower tracking error

• more accurate index replication

• better long term returns for investors

The Passive Toolkit (India)

These are the main tools you can use to build a passive investing portfolio in India:

1) Index Mutual Funds

Examples: Nifty 50, Sensex, Nifty Next 50, Nifty Midcap 150, Nifty 500

• Best for SIP investing

• No demat account needed

• “Set it and forget it” very simple for beginners

• Good for long term compounding

2) ETFs (Exchange Traded Funds)

• Give the same index exposure as index funds

• But you buy/sell them like stocks on NSE/BSE

Check:

• Daily traded volume

• Bid ask spread

Good if you want intraday control

3) Target Maturity (Debt) Index Funds/ETFs

• Debt funds based on fixed maturity dates (like 2028, 2030, 2035)

Give:

• Predictability on maturity

• Smoother returns

• Lower volatility

Useful for stability and short term goals

4) Smart Beta / Factor Index Funds & ETFs

• Follow special rules (factors): Momentum, Value, Quality, Low Vol

Try to improve returns or reduce volatility

But:

• Performance is cyclical

• Costs, turnover, and tracking error can be higher

Use only as a small satellite (not your main portfolio)

How to Choose a Good Index Fund or ETF

1) Expense Ratio (Most Important)

• Lower cost = more money stays with you.

• Even a 0.5%–1% difference can become a big amount over the long term.

• For passive funds, low cost is the main advantage, so keep this tight.

2) Tracking Error / Tracking Difference

• Shows how closely the fund follows its index.

• Lower is better because it means you’re actually getting the index return you expect.

3) Liquidity (Only for ETFs)

• ETFs trade on the stock market, so check:

• Daily volume

• Bid–ask spread

Avoid ETFs with very low volume — buying/selling becomes costly.

4) Index Methodology

• Understand how the index is built:

• How often it rebalances

• Sector limits

• Diversification rules

For Smart Beta/factor funds → know why the factor exists and when it works.

5) Comparables

• Use any MF screener to compare:

• AUM

• Expense ratio

• Past tracking error

You’re not looking for “best return”—you’re looking for clean, low cost index tracking.

A Simple, No‑Stress Passive Portfolio

This is the easiest way to invest without thinking too much.

Just divide your money into three parts:

1) Core Equity (60–70%) → Your main growth engine

Put most of your money in:

• Nifty 50 or Sensex (gives stability)

• Nifty Next 50 (future large cap winners)

Why?

You get both steady companies + fast growing potential leaders.

2) Satellite Equity (10–20%) → Small extra boost

This part gives you extra diversification.

Choose either:

• A broad market index (like Nifty 50)

OR

• One Smart Beta factor (Momentum or Low Vol), but only if you understand the risk cycles.

Why?

It adds a small “enhancer” around your core portfolio.

3) Debt (20–30%) → Safety + stability

Use:

• Target Maturity (TM) index funds/ETFs

These give:

✔ predictable maturity

✔ smoother returns

✔ less volatility than equity

Rebalance Each Year

Once a year:

• Bring your percentages back to the original plan

• Example: If equity has grown too much, shift a bit to debt

• Keep things simple and low cost

India‑Specific Trends You Should Know (2025–2026)

1) Mutual Fund industry is growing fast

In 2025, the Indian mutual fund industry grew by about 21%, and passive funds grew even faster. This means more people are choosing simple, low‑cost index funds and ETFs instead of complex products.

2) Retail SIPs are booming

More Indians are starting SIPs every month, and SIP money flowing into mutual funds is at record highs. This steady inflow is also supporting passive investing, because people now prefer simple, rules‑based investments.

3) Stronger index regulation is coming

SEBI has proposed direct regulation of index providers (for big indices like Nifty 50).

This improves:

• Transparency

• Data quality

• Investor protection

Better governance → better trust → better passive products.

FAQs

Q1) Index fund or ETF—what should I pick?

If you want SIP simplicity and don’t need intraday trading, choose index funds. If you value intraday control and can manage spreads, ETFs work. Many investors hold both.

Q2) What is tracking error? How does regulation help?

Tracking error is the volatility of the fund’s return minus its index’s return. Lower is better. A proposed Closing Auction Session (CAS) can help passives execute closer to the official close, potentially reducing tracking error.

Q3) Are passives “winning” in India?

They’re growing very fast: Passive AUM is ~₹15.0 lakh crore (Jan 2026) with ~19% share; ETF participation and volumes have scaled sharply.

Q4) Do smart‑beta/factors always beat Nifty 50?

No. Factors are cyclical; they can underperform for extended periods. Allocate cautiously and understand the rules and costs.

Q5) What new rules should I track?

SEBI’s MF‑Lite for passives and the proposal to regulate index providers of “significant indices” (e.g., ≥₹20,000 crore AUM) will shape transparency and oversight.
