Highlights:

  • Passive investing mirrors benchmark indices (e.g., Nifty 50, Sensex) without active stock selection, delivering market returns minus low costs.
  • Passive fund AUM in India has shown strong growth in recent years, driven by rising investor interest in index funds and ETFs
  • Index funds and ETFs differ in trading (end-of-day NAV vs real-time), demat requirements, and costs; both aim for low tracking error.
  • Equity-oriented passive funds are subject to standard LTCG taxation: 12.5% on gains above ₹1.25 lakh after 12 months (no indexation).

Introduction

Passive fund adoption in India continues to rise as investors seek transparency, low costs, and market-linked returns. Unlike active funds, where managers attempt to outperform through stock selection, passive strategies replicate benchmark indices such as the Nifty 50 or the Sensex.

What is Passive Investing & How Does it Work in India?

Passive investing involves holding a diversified portfolio that mirrors a benchmark index’s composition and weightage. For example, a Nifty 50 index fund holds all 50 constituent stocks in proportions matching the index. SEBI’s 2022 circular standardised passive fund operations, promoting transparency and efficiency.

The fund manager’s role is limited to operational rebalancing to match index changes (e.g., additions/deletions, corporate actions). No discretionary stock picking occurs.

Why Passive Funds are Growing Rapidly in India

Passive AUM has expanded markedly. As per AMFI data, passive funds (index funds + ETFs) reached approximately ₹15 lakh crore by June 2026.

Key Drivers:

  • Cost advantage: Passive funds typically have much lower expense ratios compared to active equity funds.
  • Transparency: Exact holdings and weights are known and publicly disclosed, replicating benchmark indices without stock selection.
  • Retail and institutional adoption: Retail passive ownership increased. Institutional flows remain dominant.

Passive inflows have been consistent, with strong contributions from equity ETFs and index funds.

Index Funds vs ETFs: Key Differences for Indian Investors

Both replicate indices but differ operationally:

  • Index Funds (Mutual Funds): Transact at end-of-day NAV. No demat account required. Suitable for SIPs/lumpsum via mutual fund platforms.
  • ETFs: Trade on exchanges like stocks in real-time (intraday prices). Require a demat account. Often lower headline expense ratios but incur brokerage, STT, and potential bid-ask spreads/premiums-discounts.

Long-term returns are similar when tracking the same index effectively. Choose based on preference: simplicity (index funds) or liquidity/trading (ETFs). Evaluate total costs, including transaction fees.

Smart Beta and Factor Investing: Enhanced Passive Strategies

Smart beta (or factor) funds bridge traditional passive and active by using rules-based indices weighted by factors like value, momentum, quality, low volatility, or multi-factor combinations, rather than pure market-cap weighting.

They remain fully passive with no discretionary stock picking.

Popular in India via ETFs and index funds tracking factor-based indices on NSE/BSE. They add a “smart” layer to core passive allocation, potentially outperforming cap-weighted benchmarks over full market cycles, though with varying tracking error and costs.

How to Choose Passive Funds: Tracking Error, Expense Ratio & Tax

  • Tracking Error: Measures deviation from the benchmark. For Nifty 50 funds, lower is better. Caused by expenses, cash drag, rebalancing, etc. Compare the historical tracking difference, too.
  • Expense Ratio: Directly impacts net returns.
  • AUM & Liquidity: Larger AUM reduces closure risk; for ETFs, check trading volumes.
  • Other: Fund house track record, replication method (physical preferred), and total cost of ownership.

Data-heavy selection prioritises low total drag (expense + tracking error).

Tax Treatment for Passive Equity Funds in India

Equity-oriented index funds and ETFs (≥65% equity) follow equity taxation:

  • Holding ≤12 months: STCG at 20%.
  • Holding >12 months: LTCG at 12.5% on gains exceeding ₹1.25 lakh per year (no indexation).

Refer to the Income Tax Department for the latest rules. Tax efficiency favours long-term holding.

Moving toward clarity in passive investing

Passive strategies deliver benchmark returns efficiently, suiting most investors’ core portfolios. With industry AUM growth and regulatory support (SEBI/AMFI), focus on low costs, tight tracking, and factor enhancements for optimisation. Combine with asset allocation and periodic review. Passive won’t beat the market but reliably captures it at minimal cost.

FAQs

1. What is the difference between index funds and ETFs in India?

Index funds transact at end-of-day NAV without needing a demat account. ETFs trade on exchanges in real-time and require demat accounts. ETFs typically have lower expense ratios but involve brokerage costs. Both replicate benchmark indices equally well.

2. What is tracking error, and why does it matter?

Tracking error measures how closely a fund replicates its benchmark index. Lower tracking error means the fund accurately mirrors index performance. It’s a key selection metric alongside expense ratio for passive investors.

3. What is the minimum investment for index funds in India?

Most index funds allow SIP (Systematic Investment Plan) investments starting from ₹100 per month. Lumpsum minimums also typically start at ₹100. This makes passive investing accessible to retail investors without requiring large initial capital.

4. How are passive equity funds taxed in India?

Equity-oriented index funds and ETFs held for more than 12 months qualify as long-term assets. LTCG (Long-Term Capital Gains) taxation applies beyond this holding period. Tax treatment follows the rules for equity mutual funds as per the provisions of the Income-tax Act.
