SEBI's new ETF pricing rules from 7 September: What's changing and why investors should care — experts explain

Starting 7 September 2026, the Securities and Exchange Board of India (SEBI) will implement significant changes to the regulatory framework governing exchange-traded funds (ETFs). These modifications affect price setting mechanisms, trading bands, pre-opening auctions, and settlement processes for equity, debt, and commodity ETFs, marking a strategic effort to align ETF prices more closely with underlying market realities.

Under the existing regime, ETFs have been constrained by a uniform price band of ±20% relative to the net asset value (NAV) from two trading days prior (T-2 NAV), with Overnight ETFs subjected to a tighter ±5% band. SEBI’s revised guidelines overhaul this method by shifting the reference for establishing an ETF’s base price from the T-2 NAV to the previous day’s closing market price, calculated as an average during the final 30 minutes of trading. This change intends to reduce discrepancies where allowed price fluctuations deviate significantly from actual market conditions.

For ETFs that do not record trades during the last 30 minutes of the preceding day (T-1), the new rules default the base price to the last traded price earlier on that day. In the absence of any trades on T-1, the base price will fall back on the most recent closing NAV. This approach aims to mitigate unrealistic pricing bands that could arise from illiquid trading, thereby reinforcing price discovery grounded in real market activity.

The regulatory adjustments introduce dynamic price banding for equity and debt ETFs, excluding Overnight and Liquid variants. These assets will commence trading with a ±10% price band around the reference price, which can expand to ±20% after a designated cooling-off interval triggered by price movements nearing the initial limit. This mechanism is designed to curb excessive volatility and prevent abrupt price swings, granting markets a brief pause to recalibrate before allowing wider fluctuations.

Commodity ETFs, including gold and silver, will adopt a distinct model with starting price bands of ±6%. These bands may be extended in 3% increments following cooling-off periods, with no preset cap on the number of expansions. This nuanced framework recognizes the unique overnight price movements in global commodity markets, which can significantly impact domestic ETF pricing upon market open.

A new pre-open call auction process will be instituted for commodity ETFs, a feature already standard in equity markets. This auction aggregates buy and sell orders before the trading session begins, facilitating a single, fair opening price that better reflects market consensus. Previously, commodity ETFs lacked this mechanism, often leading to opening prices determined by isolated trades that did not accurately represent broader market demand and supply.

The close-out settlement procedures have also been updated. For Overnight and Liquid ETFs, the close-out price calculation now involves selecting the higher value between two specified computations, whereas the existing method persists for other ETF categories. This revision aims to safeguard market integrity by ensuring appropriate penalties and settlement values when sellers fail to deliver ETF units.

Additionally, SEBI mandates harmonization of band widening across exchanges where an ETF is listed, eliminating inconsistent trading limits on platforms such as NSE and BSE. This uniformity is expected to reduce arbitrage opportunities arising purely from regulatory discrepancies rather than underlying market fundamentals.

Market participants and experts underscore that these changes seek to enhance the reliability and responsiveness of ETF pricing rather than restrict trading activity. Investors are advised to monitor indicative NAVs closely and employ limit orders to avoid transacting at prices distorted by band limits or temporary market imbalances.

SEBI acknowledges these reforms as an initial phase, with plans to transition towards using the previous day’s closing NAV (T-1 NAV) as a base price by April 2027, contingent on resolving operational challenges. This ongoing evolution reflects a commitment to refining ETF market mechanisms in step with market dynamics and investor protection priorities.

The regulatory update represents a pivotal step in modernizing India’s ETF market infrastructure, aligning pricing methods more closely with actual trading behavior and underlying asset values. As these norms take effect, investors and market operators will need to adapt to a framework that balances price stability with flexibility, aiming for a more transparent and efficient trading ecosystem.
