Why It Matters
The settlement methodology determines how the final price of an expiry contract is calculated. A VWAP (volume‑weighted average price) approach can amplify volatility when trading volume is uneven, while a blended method incorporates both VWAP and a fixed price reference to smooth outcomes. For investors, this means that the cost of hedging or speculating on Nifty 500 futures may become more stable in the short run, but the new rule also introduces a new layer of complexity that could affect liquidity and pricing efficiency over a longer horizon. Capital goods firms that use futures to hedge commodity exposure, brokerage firms that provide execution services, and technology service providers that supply trading platforms will feel the immediate effects. The change may reduce execution slippage for some traders but could also lead to higher bid‑ask spreads if market participants adjust their pricing models. **Update 10:01 AM IST:** Sebi’s phased shift in expiry settlement methodology (VWAP → blended) may ease near-term volatility but could introduce mid-term uncertainty for derivatives traders and liquidity dynamics in Nifty 500 futures.
What Happened
SEBI announced a phased shift from a pure VWAP settlement to a blended settlement methodology for expiry contracts in Nifty 500 futures. Under the new rule, the final settlement price will be calculated by combining the VWAP with a fixed reference price, weighted to reduce the impact of volume spikes. The decision was communicated through a regulatory notice and is expected to take effect over the next 12 to 18 months. The move is aimed at easing near‑term volatility that has been a concern for traders during high‑volume expiry days. The policy does not alter the underlying contract specifications, but it changes how the settlement price is derived, which can influence the cost of hedging and the liquidity profile of the futures market.

Frequently Asked Questions
What is VWAP and why does it matter?
VWAP stands for volume‑weighted average price; it is the average price of a security weighted by trading volume. It is used to calculate settlement prices in futures. A pure VWAP can make prices jump if a large trade happens, so blending it with a fixed reference smooths the final price.
Will this change affect the Nifty 50 index itself?
No. The change only affects the settlement price of futures contracts traded on the Nifty 500 index, not the underlying index values.
How will brokers benefit from the new settlement method?
Brokers may see reduced execution slippage for their clients, which can improve client satisfaction and potentially increase trading volume.
Could the new method increase trading costs?
In the short term, the blended method is designed to reduce volatility, which can lower execution costs. However, if market participants change pricing models, bid‑ask spreads could widen, potentially increasing costs.
When will the new settlement method take effect?
SEBI has announced a phased implementation over the next 12 to 18 months, but the exact start date for each expiry cycle has not been finalized.
