SEBI overhauls ETF trading framework with dynamic price bands
Synopsis
SEBI's proposed ETF overhaul tackles a structural flaw hiding in plain sight: price bands anchored to two-day-old NAV data. The shift to VWAP-based same-day pricing and a dynamic band that can breathe with the market — up to 20% intraday — is a meaningful step toward closing the gap between ETF prices and what their underlying assets are actually worth.
Key Takeaways
SEBI proposed a major overhaul of the ETF trading framework on 15 June , introducing dynamic price bands and revised base price rules.
Current fixed 20 per cent price bands for equity and debt ETFs are based on NAV from two trading days earlier — a lag SEBI aims to eliminate.
New base price will use the volume-weighted average price (VWAP) of the last 30 minutes of the previous trading session.
Dynamic bands start at 10 per cent and can expand up to 20 per cent intraday, with a 15-minute cooling-off period at each trigger point.
Liquid and overnight ETFs retain the existing fixed 5 per cent band structure.
Stock exchanges and fund houses must operationalise T-1 closing NAV as base price by 1 April 2027 .
The Securities and Exchange Board of India (SEBI) on Monday, 15 June proposed a sweeping overhaul of the regulatory framework governing exchange-traded funds (ETFs), introducing dynamic price bands, revised base price calculations, and new auction mechanisms designed to ensure ETF market prices more accurately track the value of their underlying assets.
What Is Changing and Why
Under the current framework, equity, debt, and commodity ETFs trade within a fixed 20 per cent price band, while overnight ETFs operate under a 5 per cent limit. Critically, these bands are anchored to a reference price derived from the ETF's net asset value (NAV) from two trading days earlier — a one-day lag that SEBI says may fail to capture real-time movements in underlying securities and commodities.
The regulator's consultation paper flags this structural gap as the primary driver of the proposed changes. This is notably the first comprehensive revision to ETF trading mechanics in several years.
New Base Price Calculation
Under the proposed framework, the base price for ETF trading will shift to the previous day's closing market price, calculated using the volume-weighted average price (VWAP) during the final 30 minutes of the trading session. If no trades occur in that window, the last traded price applies. If no trades take place throughout the day, the most recent available closing NAV will serve as the reference price.
SEBI has also directed stock exchanges and mutual fund houses to work together to facilitate the use of T-1 closing NAV as the base price from 1 April 2027, addressing operational complexities that would need to be resolved ahead of that deadline.
How the Dynamic Band Mechanism Works
For equity and debt ETFs — excluding liquid and overnight funds — trading will initially be permitted within a 10 per cent band above or below the base price. If trades reach or exceed 9.9 per cent of the limit, a 15-minute cooling-off period is triggered. After the cooling-off window, the band may expand by an additional 5 per cent of the base price.
This expansion can be repeated twice in the same direction during a session, effectively allowing the trading band to widen to as much as 20 per cent intraday. If the trigger occurs within the final 30 minutes of trading, the cooling-off period is shortened to five minutes. According to SEBI, any band expansion will apply uniformly across all stock exchanges and only in the direction of the prevailing price movement.
What Stays the Same
Liquid ETFs and overnight ETFs will continue to operate under the existing fixed 5 per cent price band structure, given their lower volatility profile and distinct investor base.
What Comes Next
The proposals are currently in the consultation phase, with market participants expected to submit feedback before any final circular is issued. The 1 April 2027 target for T-1 NAV-based base pricing gives exchanges and fund houses roughly nine months to resolve operational hurdles. How quickly SEBI finalises and implements the framework will determine whether the long-standing gap between ETF market prices and underlying asset values is meaningfully narrowed.
Point of View
But the real test is execution: getting exchanges and fund houses to align on T-1 NAV operationalisation by April 2027 is an ambitious timeline given the plumbing involved. The dynamic band design — breathing room up to 20% with cooling-off buffers — is more sophisticated than a blunt fixed cap, but it also introduces new complexity that smaller market participants may struggle to navigate. The consultation phase will reveal whether the industry sees this as a fix or a fresh compliance burden.

Frequently Asked Questions
What is SEBI's proposed ETF framework overhaul?
SEBI has proposed replacing the existing fixed price band structure for ETFs with a dynamic price band mechanism, alongside a shift to VWAP-based base price calculations. The changes aim to ensure ETF market prices more accurately reflect the real-time value of their underlying assets.
How does the new dynamic price band work for equity and debt ETFs?
Trading will begin within a 10 per cent band above or below the base price. If trades hit 9.9 per cent of the limit, a 15-minute cooling-off period is triggered, after which the band can expand by an additional 5 per cent. This can happen twice in one direction per session, widening the effective band to 20 per cent intraday.
What is the new base price calculation under the proposed rules?
The base price will be the previous day's closing market price, calculated using the volume-weighted average price (VWAP) of the final 30 minutes of trading. If no trades occurred in that window, the last traded price is used; if no trades happened all day, the most recent closing NAV applies.
When will the T-1 NAV base price take effect?
SEBI has set 1 April 2027 as the target date for stock exchanges and mutual fund houses to operationalise T-1 closing NAV as the base price. The regulator has asked both parties to work together to resolve operational issues ahead of that deadline.
Are liquid and overnight ETFs affected by the proposed changes?
No. Liquid ETFs and overnight ETFs will continue to operate under the existing fixed 5 per cent price band structure, unchanged by the proposed framework overhaul.
