Indian Mutual Fund Industry Overview
The Indian mutual fund industry concluded December 2025 with a robust total Assets Under Management (AUM) of ₹80.23 lakh crore. This figure represents a substantial increase over the years, indicating deepening penetration and financialization of savings within the country. The industry has seen a multi-fold increase in AUM over the past decade, reflecting growing investor confidence and participation.
Rise of Passive Investing
A dominant theme in the industry is the accelerating growth of passive investments. Assets under management in passive funds surged by 31% year-on-year, reaching ₹14.20 lakh crore by the end of December 2025, up from ₹10.85 lakh crore in the previous year. Consequently, the proportion of passive funds within the total industry AUM has grown considerably, rising from 12% in December 2021 to 18% in December 2025. This upward trend highlights a clear shift in investor preference towards cost-efficient, diversified investment vehicles. Equity-linked passive strategies continue to be the primary driver, accounting for approximately 69% of all passive AUM. While passive debt funds saw a minor dip in their share, passive equity remains a key growth area.
Active Fund Performance and Investor Preferences
Despite the ascendance of passive strategies, active fund categories remain a significant part of the market. Over the twelve months leading up to December 2025, flexi-cap funds led net sales, attracting ₹80,979 crore in inflows, signaling sustained investor interest in flexible allocation mandates. Arbitrage funds also demonstrated notable performance, recording net sales of ₹72,318 crore, appealing to investors seeking to capitalize on market inefficiencies. In the debt segment, December 2025 saw mixed flows, with categories like money market funds registering substantial inflows of ₹66,994 crore, while others experienced quarter-end adjustments.
Geographic and Investor Diversification
The reach of mutual fund investments is extending beyond major metropolitan areas. Assets originating from B15 cities (beyond the top 30) increased their share to 35% of the total AUM as of September 2025, with B30 cities showing faster growth rates. This expansion indicates a widening investor base across Tier 2 and Tier 3 regions. Maharashtra continued to be the largest contributor to mutual fund investments, followed by Delhi, Karnataka, and Gujarat. On the investor side, retail participants hold a significant 44% of equity fund investments, slightly surpassing High Net Worth Individuals (HNIs) at 42%. Corporates remain dominant in the debt fund segment, holding approximately 70% of that AUM.
Industry Drivers and Outlook
The growth in mutual funds is underpinned by several factors, including increasing financial literacy, enhanced digital access to investment platforms, and the consistent popularity of Systematic Investment Plans (SIPs). SIP monthly contributions reached an all-time high of over ₹31,000 crore in December 2025, with the number of contributing SIP accounts also hitting a record of 9.79 crore. Globally, Franklin Templeton managed $1.53 trillion in assets as of March 31, 2025, underscoring the scale of international players operating within India. The trend towards passive investing, driven by low costs and diversification, is expected to continue shaping the industry landscape. Specialized Investment Funds (SIFs) are also a nascent but growing segment, managing approximately ₹4,892 crore.
