How SEBI Categorizes Mutual Fund Schemes
Before 2017, Indian mutual fund houses could — and did — launch several schemes that looked almost identical, just under different names. SEBI's categorization circular put an end to that by defining a fixed set of categories and limiting each fund house to one scheme per category. It sounds like a dry compliance rule, but it is the single reason a fund comparison in India means anything at all.
The Problem Before Categorization
Prior to SEBI's categorization framework, AMCs had an incentive to launch new schemes rather than grow existing ones — a fresh New Fund Offer generates a marketing push and a clean sales story, even if the AMC already ran a scheme investing in a nearly identical universe of stocks or bonds. Over time this produced a crowded, overlapping product shelf: an investor comparing two “large cap” funds from the same fund house might find they held largely the same companies in similar proportions, just marketed under two different names with two separate expense structures. There was no consistent definition of what counted as large cap, mid cap, or balanced, so even the labels themselves were unreliable across AMCs.
What SEBI's Categorization Circular Did
SEBI addressed this by defining a standard set of scheme categories grouped under broad buckets — equity, debt, hybrid, solution-oriented, and others — with each category given a precise definition of what it must invest in. A large cap equity fund, for instance, is defined by where in the market-capitalization ranking its holdings must sit, not by how the fund house chooses to brand it. Debt fund categories are similarly defined by the maturity profile and credit quality of the instruments a scheme is allowed to hold. Once these definitions existed, SEBI required every AMC to map its existing schemes into this fixed list of categories and to either merge, rename, or wind down schemes that did not fit cleanly.
The One-Scheme-Per-Category Rule
The part of the framework with the most lasting effect is a simple constraint: within most equity, debt, and hybrid categories, a single AMC is generally permitted to run only one scheme per category (with a few narrowly defined exceptions, such as index funds, ETFs, and sector or thematic funds, where multiple offerings tracking different indices or sectors are allowed). A fund house cannot run two separate large cap funds competing for the same investors and the same pool of eligible stocks. This forced AMCs to consolidate overlapping schemes and stopped the practice of quietly launching near-duplicate products to chase distributor commissions or NFO marketing cycles.
The effect compounds over time. Because an AMC cannot simply spin up a new large cap fund whenever it wants a fresh sales narrative, it has to compete within its one large cap offering — on manager skill, cost, and consistency — rather than by proliferating look-alike products. It also means that when an investor sees “large cap fund” next to a fund house's name, there is exactly one such scheme to consider from that AMC, not three or four with subtly different histories.
Why This Is What Makes Comparison Possible
Categorization is not just a labeling exercise — it is the foundation that makes an apples-to-apples fund comparison possible in the first place. Because every large cap fund across every AMC is now bound by the same definition of what a large cap fund must hold, comparing Fund A's large cap offering against Fund B's large cap offering is a comparison of two schemes operating under the same constraints. Without a shared category definition, a “large cap” fund at one AMC could quietly behave like a multi cap fund at another, and any comparison of their returns, risk, or cost would be comparing two different things wearing the same label. The detailed mechanics of what to actually look at once two funds are confirmed to be in the same category — expense ratio, AUM trend, manager tenure, and more — are covered in the guide on how to compare two mutual funds side by side, but none of that analysis is meaningful until the category match is confirmed first.
This is also why category is usually the very first filter to apply when researching funds, rather than an afterthought. If you want to see this in practice, you can filter funds by category on the screener to pull up every scheme SEBI classifies the same way, which narrows the field down to funds that are genuinely built to do the same job before any other comparison begins.
The Categories at a Glance
Equity categories run from large cap through mid cap and small cap, along with multi cap and flexi cap funds that can move across market capitalizations, plus a range of thematic and sectoral funds tied to a specific industry or investment style. Debt categories are organized primarily by maturity and credit exposure — from very short-duration, low-risk options through longer-duration and credit-risk-oriented schemes. Hybrid categories blend equity and debt in varying proportions, and solution-oriented categories are built around a specific goal, such as retirement or a child's education, typically with a minimum lock-in. Each of these categories carries its own precise eligibility rules for what a scheme is permitted to hold, which is what keeps the label on the tin consistent with what is actually inside the fund.
What Categorization Does Not Guarantee
It is worth being clear about the limits of this framework. Categorization standardizes what a scheme is allowed to invest in — it does not standardize or guarantee performance, cost, or quality of management within that category. Two large cap funds can sit in the exact same SEBI category and still differ meaningfully in expense ratio, portfolio concentration, and the track record of the person managing them. Categorization is the precondition for a fair comparison, not a substitute for doing one.
This guide is educational and explains a regulatory framework rather than recommending any specific fund or category as suitable for a particular investor. Category, goals, time horizon, and risk appetite should be discussed with a qualified financial advisor before investing.
Frequently Asked Questions
- Can a single AMC ever run more than one fund in the same category?
- Generally no, for most active equity, debt, and hybrid categories — the one-scheme-per-category rule exists specifically to prevent this. The main exceptions are passive products like index funds and ETFs tracking different underlying indices, and sector or thematic funds tied to different themes, since those are inherently distinguished by what they track rather than by strategy alone.
- Does a fund's category ever change after it is launched?
- It can, though not routinely. An AMC may reclassify or merge a scheme if its mandate no longer fits its original category cleanly, or if SEBI updates the category definitions themselves. Any such change is disclosed to existing investors, since it can alter the fund's risk and investment style.
- Are index funds and ETFs categorized the same way as active funds?
- They fall under their own dedicated category rather than being folded into the active large cap, mid cap, or other active buckets, since their mandate is to track an index rather than to be actively managed against a market-cap definition.
- Does categorization apply to debt and hybrid funds too, or only equity?
- It applies across the board. Debt fund categories are defined by maturity and credit quality, hybrid categories by the equity-debt mix, and solution-oriented categories by their goal and lock-in — each with the same one-scheme-per-category constraint that applies to equity funds.
