🔴 BREAKING — SEBI issued a circular dated 15 June 2026 overhauling how Exchange Traded Funds (ETFs) are priced and traded on Indian exchanges. Most changes take effect 1 September 2026, with a final migration to T-1 closing NAV by 1 April 2027.
India's ETF market has crossed ₹10 lakh crore (₹10 trillion) in assets. Yet the rules that decided an ETF's daily reference price and circuit limits were built for a much smaller, slower market. SEBI's new framework fixes the part retail investors felt most: ETFs that regularly traded 2-4% away from their real value.
Here is what is changing, why it matters, and what you should do about it.
What's changing — five key points
1. Base price moves from T-2 to T-1. Until now an ETF's reference (base) price for the day was the Net Asset Value from two days ago (T-2). From September it becomes the previous day's closing VWAP — the volume-weighted average price over the last 30 minutes of trade. If there were no trades in that window, the last traded price is used. If the ETF did not trade at all that day, the latest available NAV is used.
2. Fixed ±20% bands become dynamic. Every ETF, liquid or illiquid, used to get the same fixed ±20% price band. The new bands flex with the volatility of what the ETF actually holds. Equity and debt ETFs (excluding liquid and overnight funds) start with a ±10% band. Once price moves hit a 9.90% threshold, a cooling-off period kicks in before the band widens. Liquid and overnight ETFs get tighter bands. Gold and silver ETFs follow separate commodity rules.
3. A pre-open call auction for ETFs. ETFs now get a pre-open session like individual stocks. Buy and sell orders are collected and matched at a single equilibrium price before continuous trading begins. This removes the sharp price gap that used to appear at the 9:15 open, which hurt commodity ETF holders most.
4. Gold and silver ETF valuation already changed. Since 1 April 2026, gold and silver ETF NAVs are based on a domestic pooled spot price from Indian exchanges, derived from physically delivered gold and silver derivatives — not the LBMA international benchmark. This keeps Indian ETF prices closer to what Indian buyers actually pay and reduces the India-versus-global price gap.
5. A hard industry deadline. Stock exchanges and Asset Management Companies must implement the September package together by 1 September 2026, and complete the full move to T-1 closing NAV as the base price by 1 April 2027.
The problem SEBI is solving
Think about what T-2 pricing meant. On a Wednesday, the reference price anchoring your ETF's trading band was its value from Monday. Markets move a lot in two days. When the underlying index rose sharply, the ETF's stale reference price sat well below reality, and the traded price could drift far from fair value.
That gap is the premium or discount you may have noticed. Buy a Nifty 50 ETF at a 2% premium and you have handed away 2% before the investment does anything. Worse, the gap was predictable enough that fast institutional desks could trade around it, while a retail investor placing a market order absorbed the bad price.
Stale pricing plus a one-size band meant a calm, liquid Nifty ETF and a thin sector ETF were treated identically. T-1 pricing and volatility-linked bands fix both halves of that problem.
Before vs after
| Aspect | Old rule | New rule (effective Sep 2026) |
|---|---|---|
| Base price | T-2 NAV (2 days old) | T-1 VWAP (yesterday's close) |
| Price band | Fixed ±20% for all ETFs | Dynamic, starts at ±10% with a 9.90% cooling-off trigger |
| Gold/silver ETF valuation | LBMA international benchmark | Indian exchange domestic spot (live since Apr 2026) |
| Pre-open auction | None | Yes, call auction before continuous trade |
| 2027 target | — | T-1 closing NAV as base price |
What this means for you
If you buy or sell ETFs, the practical effects are direct:
- Smaller premium and discount. A reference price set from yesterday tracks reality far better than one set from two days ago. The price you pay should sit closer to NAV.
- Better price discovery at the open. The pre-open auction sets one fair opening price instead of a jumpy first few trades you might get caught in.
- Less room for gaming. When the reference price is current, the easy gap that informed desks exploited mostly disappears. That levels the field for retail orders.
- Fewer wrong circuit halts. Volatility-linked bands mean a calm ETF is not frozen by a band built for a wild one, and a genuinely volatile one gets a cooling-off pause instead of a hard stop.
A simple habit still helps: check the ETF's live NAV (the AMC and exchange both publish an indicative NAV through the day) before placing a large order, and prefer limit orders over market orders.
Which ETFs benefit most
The investors who gain the most are those holding less liquid ETFs, where stale pricing and the fixed band did the most damage:
- Gold and silver ETFs — already on domestic spot valuation since April 2026, and helped further by the pre-open auction.
- Sector and thematic ETFs — thinner volumes meant wider gaps from NAV under the old rules.
- Liquid and overnight ETFs — get purpose-built tighter bands suited to their low volatility.
Large, heavily traded funds such as the popular Nifty 50 ETFs from Nippon, HDFC, ICICI and SBI already traded close to NAV, so their gains are smaller but still real, mostly at the open.

Frequently asked questions
What is SEBI's ETF framework revamp? It is a set of trading rule changes in SEBI's 15 June 2026 circular. The reference (base) price moves from T-2 NAV to T-1 VWAP, fixed ±20% price bands become dynamic and volatility-linked, and ETFs get a pre-open call auction. The goal is to keep ETF prices closer to their true value.
When do the new ETF rules take effect? Most changes apply from 1 September 2026. Gold and silver ETF valuation already changed on 1 April 2026. The full move to T-1 closing NAV as the base price is targeted for 1 April 2027.
How does T-1 pricing help retail investors? A reference price set from yesterday tracks the market far better than one set from two days ago. That shrinks the premium or discount between an ETF's traded price and its real value, so you are less likely to overpay when buying or get underpaid when selling.
Will my Gold ETF NAV change? The basis for valuation already changed in April 2026 — gold and silver ETF NAVs now use a domestic pooled spot price from Indian exchanges instead of the LBMA international benchmark. Your holdings are unchanged; the NAV simply tracks Indian gold prices more closely.
Which ETFs are affected by dynamic price bands? All ETFs. Equity and debt ETFs (excluding liquid and overnight funds) start at a ±10% band with a 9.90% cooling-off trigger. Liquid and overnight ETFs get tighter bands. Gold and silver ETFs follow separate commodity rules.
