Exchange Traded Funds (ETFs) in Indian Markets

What an ETF actually is in the Indian market

An Exchange Traded Fund is a pooled investment vehicle that holds a defined basket of assets and lists its units on a stock exchange. In India those units trade on the NSE and BSE during market hours, so you can buy or sell them through any regular trading and demat account using a live price, exactly the way you would trade Reliance or HDFC Bank. The fund itself is run by an Asset Management Company under a SEBI registered mutual fund structure, which is why an ETF is legally a mutual fund scheme even though it behaves like a share when you trade it.

Most Indian ETFs are passive. They do not try to beat the market. A Nifty 50 ETF simply holds the 50 constituent stocks of the Nifty 50 in the same weights as the index, so when the index moves up or down by a percentage, the ETF aims to move by almost the same percentage. The small gap between the two is called tracking error, and it comes from the expense ratio, the timing of dividends, and the cash the fund holds. Because there is no active stock picking, expense ratios are low, often between 0.03% and 0.50% a year for large index ETFs.

It helps to separate three numbers that often get confused. The NAV is the true per unit value of the assets the fund holds, struck once a day. The iNAV, or indicative NAV, is an estimate of that value broadcast every few seconds during trading so you can judge fairness in real time. The market price is whatever buyers and sellers agree to on the exchange at that moment. In a liquid ETF these three stay very close together. In an illiquid one the market price can drift well away from the iNAV, and that gap is a real cost you pay.

How creation and redemption keep the price honest

The mechanism that pins an ETF price to its NAV is creation and redemption run by large institutions called Authorised Participants. When ETF units trade at a premium to the value of the underlying basket, an AP buys the actual underlying shares, hands the basket to the AMC, receives newly created ETF units, and sells those units on the exchange for a small profit. That selling pressure pushes the ETF price back down toward NAV. When units trade at a discount, the reverse happens: the AP buys cheap ETF units, redeems them with the AMC for the underlying shares, and sells the shares. This is the arbitrage that, in theory, removes any persistent premium or discount.

For a retail trader the practical takeaway is simple. In a deeply traded ETF such as a Nifty 50 or a Nifty Bank ETF, the arbitrage works smoothly and you can usually transact within a paisa or two of fair value. In a thin sectoral or thematic ETF the arbitrage works slowly because fewer APs are active, the underlying basket may be costly to trade, and screen volumes are low. That is when you see an ETF quoted several percent away from its iNAV, and that gap is money lost on entry or exit.

How ETFs are taxed in India after the July 2024 changes

This is where most older guides are now wrong, so read carefully. The Union Budget 2024 changed capital gains rules with effect from 23 July 2024. For an equity oriented ETF, meaning an ETF that holds at least 65% in domestic equity, such as a Nifty 50 ETF, a Nifty Bank ETF, or a Nifty Next 50 ETF, the holding period split is at 12 months. If you sell within 12 months the gain is a short-term capital gain taxed at 20% under Section 111A. The old 15% rate no longer applies to sales on or after that date.

If you hold an equity ETF for 12 months or more, the gain is a long-term capital gain taxed at 12.5% under Section 112A, and crucially the first Rs 1.25 lakh of total long-term equity gains in a financial year is exempt. The earlier figures of a 10% rate and a Rs 1 lakh exemption are out of date. There is no indexation on equity ETFs. A 4% health and education cess applies on the tax, and a surcharge can apply at high incomes, though the surcharge on these capital gains is capped at 15%.

Debt ETFs and most non equity ETFs follow a different and tougher rule. After the April 2023 amendment, specified mutual fund units that hold less than 35% in domestic equity lost their long-term indexation benefit. For units acquired on or after 1 April 2023, the gain is added to your income and taxed at your slab rate regardless of how long you held, so the older line about debt ETFs enjoying 20% with indexation after three years is no longer correct for new purchases. Gold ETFs were also re categorised: for gold ETF units, gains on units held 12 months or more and sold on or after 23 July 2024 are treated as long-term and taxed at 12.5% without indexation, while shorter holdings are taxed at slab. Rules differ by acquisition date, so confirm the exact treatment for your units before filing.

A fully worked example: buying a Nifty 50 ETF

Numbers here are illustrative and rounded for clarity. Suppose a popular Nifty 50 ETF trades at Rs 250 per unit and you invest Rs 2,50,000, buying 1,000 units. Assume the Nifty 50 rises 12% over the next 14 months and the ETF, with a small tracking error, rises to Rs 278 per unit. Your holding is now worth Rs 2,78,000, a gross gain of Rs 28,000. Because you held for more than 12 months, this is a long-term capital gain on an equity ETF.

Now apply the current tax. Long-term equity gains are exempt up to Rs 1.25 lakh in the year. If this is your only such gain, the entire Rs 28,000 sits inside the exemption, so the tax is zero on this trade. Contrast that with an investor who already booked Rs 1,20,000 of long-term equity gains earlier in the same year. For that investor only Rs 5,000 of the exemption remains, so Rs 23,000 of this gain is taxable at 12.5%, which is Rs 2,875, plus 4% cess of Rs 115, for about Rs 2,990 of tax. The exemption is per financial year across all your equity long-term gains, not per trade, which is why timing your sells across years matters.

Trading costs apply on top. On the Rs 2,78,000 sell value the STT on equity ETF delivery sells is 0.001%, about Rs 2.78. A discount broker may charge zero or a flat brokerage on delivery, while a full service broker may charge a percentage. There is also a small NSE transaction charge, 18% GST on brokerage plus transaction charge, SEBI turnover fees, and stamp duty of 0.015% on the buy side. For a holding of this size these costs run to a few tens of rupees, tiny against the gain, but on rapid intraday churn they add up fast.

ETFs versus index mutual funds versus active funds

Investors often weigh an ETF against an index mutual fund that tracks the same benchmark. The investing exposure is nearly identical, but the plumbing differs. An ETF trades at a live price all day and needs a demat and trading account, while an index fund transacts once a day at NAV and needs only a folio. ETFs can have lower expense ratios, but you pay brokerage and a bid ask spread each time you trade, whereas an index fund has no spread and often no transaction cost on direct plans. For a monthly SIP investor who values automation, an index fund is frequently simpler. For a lump sum or tactical trader who wants intraday entry, an ETF is the better fit.

Against an active fund, the ETF trades the hope of outperformance for certainty of low cost and full transparency. An active large cap fund might charge 1% to 2% a year and aim to beat the Nifty, but a large share of active funds struggle to beat their benchmark after fees over long periods. A Nifty 50 ETF will never beat the index, by design, yet it will rarely lag it by much either. Your choice depends on whether you believe a given manager can earn back the higher fee, which is a far less certain bet than the cost saving you get for free with an ETF.

Liquidity, spreads, and why screen volume can mislead

Liquidity is the single most underrated risk in Indian ETFs. Many investors check the day's traded volume on the screen and conclude an ETF is illiquid. That is only half the picture. Because of the creation and redemption mechanism, an ETF's real liquidity is the liquidity of its underlying basket, not just its on screen volume. A Nifty 50 ETF with modest screen volume can still absorb a large order, because an Authorised Participant can create or redeem units against the highly liquid Nifty 50 stocks behind it.

The practical guard rails are the bid ask spread and the gap to the iNAV. A broad market ETF often quotes a spread of a paisa or two, while a thin thematic ETF can show a spread of fifty paisa or more on a Rs 50 unit, which is a 1% round trip cost before you even count brokerage. The wider the spread, the more a market order hurts. This is why disciplined ETF buyers almost always use limit orders placed near the iNAV, and avoid trading in the first and last few minutes when spreads tend to widen.

• Judge liquidity by the underlying index, not only the ETF's screen volume.
• Compare the live bid and ask against the iNAV before placing an order.
• Prefer limit orders near the iNAV, especially in sectoral and thematic ETFs.
• Avoid market orders in the opening and closing minutes when spreads widen.
• Larger AMC ETFs on popular indices usually have tighter spreads and more market maker support.

Types of ETFs you can buy on Indian exchanges

The Indian ETF market has broadened well beyond plain index trackers. Broad market equity ETFs track headline indices like the Nifty 50, Sensex, Nifty Next 50, and Nifty 500. Strategy and factor ETFs follow rules based baskets such as low volatility, momentum, value, or equal weight versions of an index. Sectoral and thematic ETFs concentrate on one area such as banking, IT, healthcare, or PSU stocks, which raises both potential reward and concentration risk.

Beyond equity there are gold ETFs that hold physical gold and let you take gold exposure in demat form without storage worries, silver ETFs introduced more recently, debt ETFs that hold government securities or target maturity bond baskets, and a small set of international ETFs giving exposure to overseas indices, though new inflows into some of these have faced regulatory limits tied to overseas investment caps. Each type carries its own tax label, so always confirm whether your ETF is treated as equity oriented before you assume the equity tax rules above apply.

• Broad market: Nifty 50, Sensex, Nifty Next 50, Nifty 500 trackers.
• Factor and strategy: low volatility, momentum, value, equal weight baskets.
• Sectoral and thematic: bank, IT, pharma, PSU, consumption ETFs.
• Commodity: gold and silver ETFs held in demat form.
• Debt: government security and target maturity bond ETFs.
• International: overseas index exposure, subject to regulatory caps.

Real risks beyond a falling market

The obvious risk is market risk: a Nifty 50 ETF will fall when the Nifty 50 falls, with no manager trying to cushion the drop. That is the deal you accept for low cost and transparency. Less obvious is tracking error, the slow drift between the ETF and its index caused by fees, cash drag, and the timing of dividend reinvestment. Over many years a higher tracking error quietly eats returns, so comparing the tracking error of two ETFs on the same index is a sharper test than comparing their headline expense ratios alone.

Then there is liquidity and price gap risk in thin ETFs, where you might buy at a premium and later be forced to sell at a discount, losing money even if the index was flat. Concentration risk bites in sectoral ETFs, where a single industry shock can sink the whole holding. For international ETFs there is currency risk, since a stronger rupee can offset gains made abroad. None of these are reasons to avoid ETFs, but they are reasons to favour large, liquid, broad market ETFs for the core of a portfolio and to treat narrow thematic ETFs as small, deliberate satellite positions.

• Market risk: the ETF falls with its index, by design.
• Tracking error: fees and cash drag cause slow underperformance.
• Liquidity gap: thin ETFs can trade away from fair value.
• Concentration: sectoral ETFs ride on one industry's fortunes.
• Currency risk: international ETFs move with the rupee as well as the foreign index.

SEBI rules and how ETFs are regulated

ETFs are regulated by the Securities and Exchange Board of India under the SEBI Mutual Funds Regulations, the same framework that governs ordinary mutual funds. AMCs must disclose the full portfolio basket regularly, publish the daily NAV, and broadcast an indicative NAV through the trading day so investors can see fair value. This transparency is a core reason ETFs are considered investor friendly, because you always know what the fund holds rather than relying on periodic factsheets.

SEBI has also pushed measures to deepen ETF liquidity and protect retail investors, including norms around market making and disclosures that help keep on screen prices close to fair value. Tax rules, by contrast, are set by the Finance Act and administered by the income tax department, which is why the 2024 capital gains changes flowed from the Union Budget rather than from SEBI. Because both regulatory and tax rules evolve, you should always confirm current contract specifications, expense ratios, and tax treatment on the official AMC, exchange, and government sources before acting.

A practical checklist before you buy an ETF

Pulling the threads together, a sensible buyer runs through a short checklist rather than chasing whichever ETF is trending. First confirm the index or asset it tracks and whether it counts as equity oriented for tax. Then compare the expense ratio and tracking error against rival ETFs on the same benchmark. Next check live liquidity, meaning the spread and the gap to iNAV at the moment you want to trade, not last month's average. Finally place a limit order near fair value and keep clean records of your buy price and date for the eventual capital gains calculation.

• Confirm the underlying index or asset and its equity or debt tax label.
• Compare expense ratio and tracking error across ETFs on the same index.
• Check the current spread and the gap to iNAV, not historical averages.
• Use a limit order near the iNAV instead of a blind market order.
• Record purchase price and date so you can compute the Rs 1.25 lakh exemption and gains correctly.
