SEBI's 2026 Mutual Fund Categorisation Overhaul: Portfolio Overlap Limits, True-to-Label, and What Changes for Investors

The Securities and Exchange Board of India issued a comprehensive new circular on 26 February 2026 that overhauls the categorisation and rationalisation framework for mutual fund schemes — the first major rewrite since the original October 2017 circular. If you hold mutual funds in India, this changes what your funds are obligated to do, how they're allowed to overlap with each other, and how they must label themselves. The transition runs over three years. Here is the practical breakdown.

The five-class architecture

The 2017 circular grouped schemes into Equity, Debt, Hybrid, Solution-Oriented, and Other. The 2026 framework replaces this with five top-level classes:

1. Equity Schemes
2. Debt Schemes
3. Hybrid Schemes
4. Life Cycle Funds (new top-level class)
5. Other Schemes (Index Funds, ETFs, Fund of Funds)

The headline addition is Life Cycle Funds — schemes that automatically rebalance their equity-debt mix as the investor approaches a target retirement year. Previously such products existed under the Solution-Oriented umbrella; SEBI has now formalised them as their own class with prescribed glide paths.

Portfolio overlap limits — the most consequential change

The new circular introduces a hard cap on portfolio overlap between sectoral and thematic equity schemes within the same AMC. The intent: stop AMCs from packaging the same 25 stocks into five differently-named "thematic" funds that all underperform together when the theme rolls over.

The mechanics announced:

• Quarterly computation of pairwise portfolio overlap between all sectoral and thematic schemes within the same AMC
• Mandatory monthly disclosure of category-wise portfolio overlap percentages
• Phased realignment — AMCs have up to three years to bring overlapping schemes within the new limits, either by repositioning portfolios or by merging schemes
• The exact overlap percentage cap will be specified in subsequent operational guidelines, but industry expectation is 40%–60% maximum overlap between any two thematic schemes of the same AMC

The investor consequence: over the next three years, expect a wave of scheme mergers, particularly in the thematic and sectoral space. If you hold multiple thematic funds from the same AMC ("Infra", "Manufacturing", "Capital Goods"), one or more is likely to be merged into another. Read the merger notice carefully — your purchase date and cost basis are preserved through the merger, but the new combined scheme's mandate and benchmark may differ from the one you bought.

"True-to-label" naming and standardised descriptions

The 2017 circular allowed AMCs to differentiate schemes through marketing language even when the underlying mandates were similar. The 2026 framework mandates standardised scheme descriptions for each category. Every scheme in a given category will use the same prescribed format for its investment objective, asset allocation pattern, and benchmark — eliminating the "creative naming" that made it hard for investors to compare across AMCs.

A "Flexi Cap Fund" will look the same on paper across HDFC, SBI, ICICI, and Axis — same allocation rule (at least 65% in equities with no market-cap restriction), same benchmark (Nifty 500 TRI), same wording in the SID. You compare on actual portfolio composition, manager skill, and expense ratio. Not on marketing.

Asset allocation rules: tighter, more uniform

The market-cap definitions are unchanged from the AMFI semi-annual list — large cap = top 100, mid cap = 101–250, small cap = 251 and beyond. What's new is that the floor allocations have been raised for several equity categories. The exact percentages depend on the operational guidelines, but the direction is clear:

• Large-cap funds: equity floor raised to provide cleaner exposure
• Multi-cap funds: maintained 75% equity floor with the prescribed 25% each in large/mid/small allocation
• Flexi-cap funds: 65% equity floor with no market-cap restriction — preserved
• Aggressive hybrid: 65%–80% equity, with the equity-debt boundary clarified

The hybrid category specifically had several overlapping schemes (Balanced, Aggressive Hybrid, Equity Savings) that were hard to distinguish. The new framework draws clearer lines.

Three-year realignment timeline

AMCs are required to bring existing schemes into compliance with the new framework over a phased three-year window. The realignment can happen via:

• Portfolio repositioning (sell holdings outside the new category's universe, buy holdings inside it)
• Scheme merger (combine overlapping schemes into one)
• Scheme reclassification (move a scheme to a different SEBI category, with unit-holder consent where required)

For investors, the practical implication is that the scheme you hold in May 2026 may be a different scheme by 2029. Watch for AMC communications — every change requires a 30-day exit option without exit load, and the cost-basis is preserved through scheme mergers.

What this means for your portfolio in 2026

Action items for the next 12 months:

1. Audit thematic and sectoral fund holdings. If you own multiple thematics from the same AMC, one is likely to be merged. Decide which you want to retain before the AMC decides for you.
2. Re-read your hybrid fund's category. Conservative-hybrid, balanced-advantage, equity-savings — these were the most overlapping categories and are most likely to see consolidation.
3. Set up notification preferences with your AMC to catch the mandatory exit-window emails. If a scheme you hold reclassifies, you have 30 days to exit without load. After that, you're stuck in whatever the new scheme is.
4. Stop chasing NFOs. AMCs facing overlap-limit pressure will launch fewer new schemes for the next three years and consolidate existing ones instead. The new launches that do happen will be in genuinely new categories (Life Cycle Funds, specialised debt) where the pitch is structural, not marketing.

The deeper signal

The 2026 circular is the strongest message SEBI has sent about scheme proliferation in nearly a decade. The Indian mutual fund industry has roughly 1,300 schemes across 43 AMCs — far more than the underlying investment opportunity justifies. Many of these schemes are products invented to fill marketing slots, not investment categories with distinct return profiles. The overlap rules, the true-to-label requirement, and the three-year realignment together work to compress that count.

For the disciplined investor, this is good news. Fewer schemes per category means easier comparison. True-to-label means what's on the tin matches what's inside. Portfolio overlap limits mean an AMC can't sell you the same stocks under five different names. The rules force the industry to compete on what should have mattered all along — manager skill, cost, and return — instead of on which "theme" gets repackaged next.

Hold the funds you bought on first-principles selection. Watch for merger notices. Don't act on AMC marketing of the new framework — most of what they'll send you for the next 12 months will be communication, not investment opportunity.
