NSE & BSE Indices Futures and Options Open Interest Volume Analysis for 30/09/2025
Table of Contents
On 30th September 2025, the combined futures and options landscape was marked by aggressive repositioning—unmistakable in today’s Open Interest Volume Analysis. Nifty’s combined futures OI jumped 21.6% even as price dipped slightly, signaling that traders are building up fresh shorts across October, November, and December contracts. Rollover activity was muted at 6%, indicating this wave of new OI comes primarily from active short bets instead of extended bullish carry-overs.
Bank Nifty was the notable outlier, showing 17.4% combined OI growth driven by fresh long positions in both October and November contracts, suggesting a sector rotation toward banking strength while Nifty faces headwinds. Finnifty and Midcap Nifty reflected mixed trends: Finnifty had significant OI increases from new long buildup in November, even as October contracts saw shorts, while Midcap Nifty showed persistent shorting across all expiries.
In options, most indices reported low PCR, except MIDCPNIFTY, which saw improved put activity hinting at some bottom-fishing in midcaps. Today’s Open Interest Volume Analysis highlights a market split between determined shorting in benchmarks and selective accumulation in financials and midcaps.

Conclusion: What the NSE & BSE Indices Futures and Options Open Interest Volume Analysis Tells Us
The derivative tale for 30th September 2025 is one of cautious bearishness but with nuanced detail. Nifty’s sharp rise in combined OI, especially fresh shorts in upcoming contracts, suggests traders expect more downside, a view reinforced by the persistently low PCR in both weekly and monthly options. Bank Nifty stands apart, as long rolls and improved PCR signal that participants continue to buy dips in banking stocks even as index-wide sentiment chills.
Finnifty’s split between shorting and runaway long rolls for November reflects trader hesitancy about broader financials, while Midcap Nifty’s steady fresh short moves point to risk aversion in segments that previously led rallies. Sensex, with over 9% fresh shorts in its combined future, rounds out the picture of rising institutional caution. Overall, the Open Interest Volume Analysis points to near-term market stress and downside bias in headline indices, but savvy investors should watch banking and select midcap baskets for resilience as expiry season plays out.
