A mutual fund can become restrictive once a portfolio grows beyond a certain size. A Portfolio Management Service demands capital that most investors simply do not hold. Specialised Investment Funds and Alternative Investment Funds were designed to sit in the space between the two options, each governed by its own distinct regulatory framework. Investors evaluating SIF vs AIF need to understand this distinction before allocating capital.
Key Takeaways
-
SIF requires ten lakh; AIF requires one crore.
-
SIF follows mutual fund regulations. AIF has built its own separate framework instead.
-
AIF opens the door to private, unlisted assets that SIF cannot offer.
-
Risk, exit timelines, and tax treatment diverge sharply across the two structures.
What Is a Specialised Investment Fund (SIF)?
SEBI created the SIF category in 2025, positioning it between a mutual fund and a PMS. It operates under mutual fund regulations. The minimum investment is ₹10 lakh, and fund managers get room to run strategies such as long-short equity and sector rotation.
What is an Alternative Investment Fund (AIF)?
An Alternative Investment Fund (AIF) is a privately managed fund regulated under the SEBI (AIF) Regulations, 2012. SEBI classifies these funds into these three categories:
-
Category I backs startups and infrastructure, frequently with government incentives attached.
-
Category II is the broadest, covering private equity, debt, and real estate.
-
Category III goes further still, permitting derivatives and leverage in strategies that resemble a hedge fund. Entry typically costs ₹1 crore, dropping to ₹25 lakh for employees or directors of the fund.
Key Differences Between SIF vs AIF

Potentially higher, tied to illiquid or complex bets |

Benefits of Investing in SIF
SIF opens access to strategies such as long-short equity and sector rotation, all inside a structure SEBI continues to regulate. Its ₹10 lakh minimum sits well below what a PMS or AIF demands, making it one of the more accessible ways into advanced investing strategies.
Benefits of Investing in AIF
AIF reaches asset classes no mutual fund or SIF can touch, like startups, private equity, real estate and hedge-style trades. Category I adds an incentive through tax breaks for startup and infrastructure investments. Category III pursues sharper returns through leverage and derivatives. Investors willing to sit with illiquidity for a long stretch pick up real diversification here, beyond what stocks and bonds alone provide.
Risks of SIF and AIF
Risk shows up differently in each. SIF strategies may include short positions or heavy concentration in a single sector, both of which can produce losses when markets turn down. AIF adds a layer SIF mostly avoids: capital locked away for years, exits that are not always available on demand, and private assets that are genuinely hard to price. The real question in SIF vs AIF risk comes down to how much illiquidity an investor can tolerate.
Who Should Invest in an SIF and Who Should Invest in an AIF?
SIF fits investors who have outgrown a plain mutual fund but are not ready to commit ₹1 crore to an AIF. Most fall into a three to five year horizon, comfortable with moderately complex strategies like long-short equity.
AIF fits a different investor altogether: individuals with higher-net-worth and institutions with a longer runway, tolerance for illiquidity, and genuine interest in startups, private equity, or hedge-style trading.
Conclusion
Capital available, liquidity needs, and risk tolerance decide the SIF vs AIF question in most cases. SIF offers the more accessible, regulated path into advanced strategies. AIF opens private markets, at the cost of higher minimums and longer lock-ins.
