Passive investment in India has soared, with mutual fund assets reaching ₹85.76 lakh crore by July 2026. While market experts are now discussing the potential for state-specific indices to capture regional economic trends, exchanges have not announced any such plans. Investors should note that while this concept offers new diversification, it also carries unique risks like liquidity challenges and market concentration.
The landscape of passive investment in India is evolving rapidly as retail and institutional investors increasingly shift toward index-based strategies. By July 2026, the total assets under management (AUM) for mutual funds in India climbed to ₹85.76 lakh crore. Within this, passive funds—such as exchange-traded funds (ETFs) and index funds—have seen significant growth, reaching an AUM of ₹15.15 lakh crore. This surge highlights a clear investor preference for simple, low-cost ways to track market performance.
Building on this momentum, market experts have begun discussing the potential for state-specific or regional indices. The idea is to create benchmarks that mirror the growth of major corporate hubs like Maharashtra, Gujarat, Tamil Nadu, and Karnataka. Similar to regional equity indices in global markets, such a product would theoretically allow investors to bet on the economic health and policy success of specific states. This concept aims to capture the spirit of competitive federalism, where states vie to attract industrial growth and investments.
However, it is important for investors to distinguish between market discussions and official exchange plans. As of early September 2026, neither the National Stock Exchange (NSE) nor the Bombay Stock Exchange (BSE) has officially announced the launch of state-specific indices. Instead, the exchanges have been focusing on expanding their sectoral and thematic offerings. For instance, the NSE recently launched 11 new sectoral indices, continuing a trend of refining benchmarks that track specific industries rather than geographical regions.
For investors, the potential introduction of regional indices carries both opportunities and notable risks. On the positive side, these products could offer a new layer of diversification, helping investors gain exposure to the specific economic strength of a state. However, they also introduce concentration risk. An index heavily weighted toward one state could be disproportionately impacted by state-specific policies, natural disasters, or regional industrial downturns.
Liquidity is another critical factor. Regional indices might include smaller companies or stocks that do not trade frequently. If an index is comprised of illiquid stocks, it could become difficult for fund managers to track the index accurately or for investors to exit their positions without causing large price swings.
Furthermore, the regulatory environment is currently cautious regarding the rapid expansion of passive fund products. The Securities and Exchange Board of India (SEBI) has been reviewing the proliferation of these funds to ensure they do not create confusion or lead to unnecessary risk for retail investors. Any future launch of specialized, regional benchmarks would likely require strict compliance with regulatory guidelines to ensure transparency and stability. Investors interested in this space should keep a close watch on future exchange filings and SEBI circulars rather than market speculation, as these will be the only reliable indicators of any new product developments.
