The FII DII data October 2026 shows foreign investors sold ₹51,466 crore in the cash market between 1 and 23 October, while domestic institutions bought ₹59,110 crore. That is NSE provisional data across 15 sessions. The surprise is the trend: FIIs turned net buyers on 23 October, yet the Nifty still fell. Here is the week-by-week picture.
Key Takeaways
- FIIs sold ₹51,466 crore and DIIs bought ₹59,110 crore in the cash market from 1 to 23 October 2026.
- About 77% of the month’s foreign selling came in the first six sessions.
- FIIs were net buyers on 16, 21 and 23 October; DIIs sold only on 16 October.
- On 23 October both groups bought, yet the Nifty slipped 0.39% to 22,600 as crude jumped.
- NSE and NSDL numbers differ because NSDL also counts IPO and QIP money.

FII DII Data October 2026 at a Glance
FIIs (foreign institutional investors) are overseas funds; DIIs (domestic institutional investors) are Indian mutual funds, insurers, banks and pension funds. These are the numbers we track each evening, as of the close on Friday, 23 October 2026:
- FII net cash flow, 1 to 23 October: minus ₹51,466 crore.
- DII net cash flow, 1 to 23 October: plus ₹59,110 crore.

Depository data tells a similar story on a wider base. A PTI report on 25 October put FPI (foreign portfolio investor) outflows at ₹48,056 crore for October so far and about ₹3.08 lakh crore for 2026. Our FPI outflow 2026 month-wise breakdown covers the full year. The daily numbers below show how that selling actually unfolded.

Week-by-Week Trend: Foreign Selling Faded
- 1 to 9 October (6 sessions): FIIs sold ₹39,778 crore and DIIs bought ₹40,356 crore. That is about 77% of the month’s foreign selling.
- 12 to 16 October (5 sessions): FIIs sold ₹8,990 crore and DIIs bought ₹7,812 crore.
- 19 to 23 October (4 sessions): FIIs sold only about ₹2,698 crore while DIIs bought ₹10,941 crore. Our weekly FII DII report for the week ending 23 October has the full breakdown.
Average daily FII selling fell from about ₹6,630 crore in the first week to under ₹700 crore in the third. So what drove the change?
Why FIIs Sold in October 2026, and Why the Pace Slowed
Analysts quoted by PTI on 25 October gave a consistent list:
- Crude oil: Choice Wealth’s Dheeraj Gaur blamed high crude prices first. Brent December futures traded near $114 a barrel on 23 October, a five-month high, according to Kotak Neo.
- US rates: The US 10-year yield had crossed 5.2% by 13 October (Business Standard), keeping dollar assets attractive.
- Earnings worries: MIRA Money’s Anand K Rathi pointed to concerns over the earnings outlook.
The slowdown had clear causes too. Geojit’s V K Vijayakumar credited the US 10-year yield easing from 5.36% to around 5%, the rupee firming to 94.94 per dollar and attractive large-cap valuations. PTI also noted that the ₹30,213 crore Jio Platforms IPO, open from 21 to 23 October, temporarily absorbed market liquidity, a theme we covered in why FPIs sold stocks but bought IPOs. On the domestic side, record SIP flows kept DIIs well funded, as covered in our SIP inflow September 2026 report. The next question is how to read a single day of this data.
How to Read a Day of FII DII Data: The 23 October Example
- Net flow: FIIs +₹888 crore, DIIs +₹3,235 crore, so the combined flow was +₹4,123 crore.
- Size: Compared with roughly ₹675 crore of average daily FII selling that week, a buying day is a clear change.
- Price: The Nifty still fell 0.39% to 22,600. Flows and price disagreed.
- Breadth: The Nifty Midcap 100 lost 2.21% and the Smallcap 100 lost 2.94%. So the selling came from participants outside the FII and DII groups.
- Derivatives: Check FII index futures positioning with the FII long short ratio before trusting a cash buying day.
The lesson: positive institutional flows do not guarantee a green close; breadth usually explains the gap.
Why FII DII data October 2026 differs between NSE and NSDL
NSE provisional data, released around 6 PM IST on trading days, covers only exchange trades. NSDL final FPI data comes the next working day and includes IPOs and QIPs. For 1 to 12 October, NSE showed about ₹41,487 crore of FII selling while NSDL showed ₹47,417 crore. Our FII vs FPI guide explains the overlap. With that in mind, here is what to watch next.
Checklist for the Last Week of October 2026
- Track the combined FII plus DII figure each evening, not just the FII headline.
- Compare each day’s FII number with its five-day average.
- Watch Brent crude near $114 and the US 10-year yield near 5%.
- Note the events Bajaj Broking’s Pabitro Mukherjee flagged: the US Fed and Bank of Japan decisions, US GDP data and the earnings season.
- Wait for NSDL data before drawing month-end conclusions.

Frequently Asked Questions
What does the FII DII data October 2026 show so far?
NSE provisional data shows FIIs sold ₹51,466 crore and DIIs bought ₹59,110 crore in the cash market from 1 to 23 October 2026. DIIs more than absorbed the foreign selling, leaving a combined inflow of about ₹7,644 crore.
Which day saw the biggest FII selling in October 2026?
8 October 2026 was the heaviest day, with FIIs selling ₹12,944 crore in the cash market. DIIs bought ₹10,703 crore the same day, so the combined flow was about minus ₹2,241 crore.
Did FIIs buy any day in October 2026?
Yes. FIIs were net buyers on 16 October (₹1,166 crore), 21 October (₹1,022 crore) and 23 October (₹888 crore), according to NSE provisional data.
What time is FII DII data released?
NSE provisional FII and DII cash market data usually comes around 6 PM IST on trading days. NSDL final FPI data is released the next working day and can differ because it also includes primary market investments.
Why did the Nifty fall on 23 October when FIIs and DIIs both bought?
Crude oil jumped to a five-month high and selling hit mid and small caps, with the Nifty Midcap 100 down 2.21% and the Smallcap 100 down 2.94%. Institutional buying was not enough to offset selling by other participants.
The Bottom Line
October 2026 has been another heavy month for foreign selling, but almost all of it came early. Since mid-month the pace has dropped sharply, FIIs have bought on three days, and DIIs have kept buying more than FIIs sold.
The 23 October session is the warning: even with both groups buying, crude pushed the market lower. Our practical next step is to treat a run of FII buying as meaningful only if Brent eases and the Nifty confirms it with a higher close.
