Mutual fund inflows September 2026 told a clear story: domestic equity investors kept putting money in even as markets slid and foreign portfolio investors (FPIs) sold Indian shares. As per Association of Mutual Funds in India (AMFI) September 2026 data, equity schemes took in net inflows of ₹38,306.55 crore in the month. That’s nearly 31% more than the ₹29,328.62 crore reported for August by outlets quoting the same AMFI release, The Economic Times among them.
Why does that matter for the stock market today in India? Mutual-fund buying is a big chunk of domestic institutional investor (DII) demand, and that demand has been soaking up FPI selling all through 2026.

Mutual Fund Inflows September 2026: Equity Schemes Lead
On AMFI’s open-ended scheme sheet, equity schemes show a September 2026 net inflow of ₹38,306.55 crore (₹74,831.96 crore mobilised, less ₹36,525.41 crore in redemptions). By category, the same sheet shows these net inflows:
- Small-cap funds: ₹9,038.57 crore
- Mid-cap funds: ₹7,834.84 crore
- Flexi-cap funds: ₹6,701.80 crore
- Large- and mid-cap funds: ₹4,271.22 crore
- Multi-cap funds: ₹3,859.55 crore
- Large-cap funds: ₹859.47 crore (back in positive territory after August outflows of about ₹1,147 crore, as reported by ET Markets)
Put small-cap and mid-cap together and they make up about 44% of the equity-scheme total. That’s our arithmetic from AMFI’s category figures. ET Markets adds that September’s equity inflow was a five-month high, and that equity funds have now seen net inflows for 67 months running.
Systematic investment plan (SIP) contributions set a monthly record of ₹32,490 crore in September, up from ₹32,297 crore in August, according to ET Markets and other outlets quoting AMFI. Keep in mind this is the monthly SIP contribution, not the equity net-inflow figure above.
Why DIIs Matter Amid FPI Selling
NSDL’s calendar-year FPI report shows foreign portfolio investors sold a net ₹35,861 crore of Indian equity in September 2026, and another ₹47,417 crore in October 2026 up to 12 October (a partial month). For the bigger picture on this foreign-selling wave, read our note on FPI outflows in 2026 and the explainer on what FII and DII mean.
ET Markets reported that the Sensex and the Nifty each fell about 6% in September, weighed down by rising crude oil prices, higher US bond yields and steady FPI selling. That’s the backdrop against which equity mutual-fund inflows went up. Put simply, retail and institutional SIP and MF money worked as a domestic cushion while foreign equity flows stayed negative.
Debt Outflows and Industry AUM Context
Not everything was rosy. AMFI data show debt-oriented open-ended schemes saw a net outflow of ₹1,83,155.76 crore in September, mostly from liquid and money-market categories (ET Markets ties much of it to advance-tax and quarter-end treasury redemptions). Across all open-ended schemes, the net outflow came to ₹1,33,060.04 crore, and their net assets under management stood at ₹82,49,221.33 crore as on 30 September 2026.
Gold ETFs pulled in net inflows of ₹4,450.61 crore and equity ETFs ₹9,959.96 crore in September, per AMFI figures reported by Upstox and ET Markets. So investors weren’t only in active equity SIPs; they were also using passive funds and safe-haven ETFs.
What It Means for Markets
If you track flows, September’s message is hard to miss. Equity mutual-fund demand held up even as the headline indices fell and FPIs sold. That doesn’t cancel out foreign selling, but it goes a long way in explaining why drawdowns have often been cushioned by domestic SIP and equity-scheme buying. We’d still treat concentration in certain categories, mid- and small-caps especially, as a risk. And read every percentage, whether the ~31% month-on-month jump in equity net inflows or the ~6% fall in the indices in September, against the exact base the source uses.
