SEBI keeps 30-minute VWAP for expiring derivatives

2026-10-15 · 1 source · BusinessLine Markets

In short

SEBI did not change the main settlement formula for expiring derivatives. The summary says those contracts will still use a 30-minute VWAP, and stock derivatives trading will now run until 3:45 p.m. on expiry days.

This matters for traders in stock derivatives because expiry-day pricing can affect their orders and results. The reporting does not say when the change starts.

What the reporting says

SEBI retained the existing derivatives settlement formula and kept expiring contracts on a 30-minute VWAP, according to the publisher-supplied summary. The reporting also says stock derivatives trading will be extended to 3:45 p.m. on expiry days. It does not state the full rationale, the start date, or whether any other settlement rules were changed.

Why it matters

This move affects stock derivatives trading and expiry-day settlement in India. Keeping the 30-minute VWAP preserves the existing formula for expiring contracts, while the later 3:45 p.m. trading cut-off changes the close for those products. The reporting does not say whether exchanges requested the tweak or whether it is intended to reduce volatility.
