MF Lite Explained: Why Index Funds in India Are About to Get Cheaper

SEBI just made it four times cheaper to start a fund house, as long as it runs only passive funds. Fee wars usually follow rules like this.

MF Lite is SEBI's lighter licence for fund houses that run only passive schemes: index funds, ETFs, and simple fund-of-funds. For you as an investor, it means one thing: more players competing to run the same Nifty 50 portfolio, which puts downward pressure on the already-tiny fees you pay for index funds.

SEBI notified the framework through the Mutual Funds (Third Amendment) Regulations on December 16, 2024, issued the operating circular on December 31, 2024, and made it effective from March 16, 2025. Here is what changed, who it lets in, and what it does and does not do for your portfolio.

What MF Lite Actually Is

Until 2025, starting any mutual fund house in India meant clearing one bar: ₹150 crore in net worth (₹100 crore under an alternate route), plus a compliance apparatus designed for firms making active stock-picking decisions with other people's money.

That made sense for active funds, where a manager's judgment can destroy value. It made much less sense for a fund house whose entire job is buying 50 stocks in the same weights as a published index. There are no stock calls to police. The main risks are operational: does the fund track the index tightly, and are costs low?

MF Lite recognises this. The regime for a passive-only AMC:

Compliance is trimmed too: trustees no longer need separate audit committees, half-yearly trustee reports are discontinued, and disclosure obligations are scaled to what a passive scheme actually needs.

Not every index qualifies. In the first phase, MF Lite schemes can track domestic equity indices where funds tracking that index collectively hold at least ₹5,000 crore in AUM (so Nifty 50, Sensex, Nifty Next 50 and similar broad indices qualify), overseas indices above USD 20 billion, government securities and target maturity debt indices, and gold and silver ETFs. SEBI also defined three hybrid passive categories: debt-oriented (25:75 equity-debt), balanced (50:50), and equity-oriented (75:25), each needing a ₹10 crore minimum initial corpus.

Why SEBI Did This

Two reasons, both stated plainly in the regulator's own consultation papers.

First, passive is where retail money is heading, and India has too few dedicated players. Passive AUM has grown fast, but most of it sits inside large active-first AMCs, where index funds are a side business and there is little incentive to compete hard on price. A ₹150 crore entry bar kept focused, low-cost challengers out.

Second, the compliance load was mismatched with the risk. Regulating a Nifty 50 index fund like a concentrated small-cap active fund raises costs without protecting anyone. Those costs flow into expense ratios. Cut the unnecessary compliance, and the savings can flow back to investors.

The framework also lets existing full-licence AMCs hive off their passive schemes into a separate MF Lite entity, with resources ring-fenced from the active business. A large AMC could spin its index fund lineup into a lean, cheap subsidiary.

Who Is Coming In

Here is the honest status as of August 2026: the passive-first fund houses you have heard of came in through the full AMC route, not MF Lite, mostly because they were licensed before the framework existed.

• Zerodha Fund House holds a full AMC licence and runs only passive products: index funds and ETFs, with some of the lowest expense ratios in the industry.
• Jio BlackRock received its final SEBI registration in May 2025 as a full AMC and raised roughly ₹17,800 crore in its first debt NFOs in July 2025.
• Angel One AMC received SEBI approval in November 2024 and has said it will focus exclusively on passive products.
• Navi Mutual Fund has competed on index fund pricing since 2021 under a full licence.

We have not been able to verify any named AMC that has publicly launched under an MF Lite registration yet; the framework is barely a year old, and licence pipelines take time. What MF Lite does is hold the door open for the next wave, and give SEBI a mechanism to keep entry cheap. The competitive effect is already visible in pricing, regardless of which licence the competitors hold.

What It Means for Your Money

Index fund economics are simple: the product is identical across AMCs, so the only levers are the expense ratio and how tightly the fund tracks the index. Competition attacks both.

Current direct-plan expense ratios on Nifty 50 index funds show how far the price war has already gone:

Expense ratios as published on Value Research and AMC pages, August 2026; they change periodically, so check the current factsheet before investing.

At these levels, the expense ratio stops being the whole story. Tracking difference matters just as much: the gap between what the index returned and what your fund actually delivered. It captures the expense ratio plus everything else that leaks: cash drag, transaction costs, and sloppy rebalancing. A fund charging 0.10% with a 0.35% tracking difference is worse than a fund charging 0.15% that tracks within 0.20%. When you compare index funds, compare one-year and three-year tracking difference, not just the TER on the label.

More competitors chasing the same index money means both numbers get squeezed. That is the MF Lite bet, and it is a good one for you.

What MF Lite Does NOT Change

Worth being precise here, because "new SEBI framework" headlines create anxiety they should not.

• Active funds are untouched. MF Lite is a parallel track for passive-only AMCs. Your flexi-cap fund's rules, disclosures, and taxation are exactly what they were.
• Your existing holdings keep working. Nothing about your current units, SIPs, NAVs, or capital gains treatment changes. Even if an AMC hives its passive schemes into an MF Lite entity, your units and cost basis carry over.
• Investor protection is not diluted. The relaxations are on entry capital and compliance built for active management. Custody with an independent custodian, trustee oversight, and SEBI's jurisdiction all remain. Scheme assets never sit on the AMC's balance sheet, so a fund house's ₹35 crore net worth is not what backs your ₹10 lakh.
• It is not a licence for exotic products. Only established, liquid indices qualify in phase one. No obscure thematic baskets under the lighter regime.

Our Take

Cheap beta is getting cheaper. That is the entire story, and it strengthens an argument we keep making: the core of most portfolios should be broad, boring, low-cost index exposure, with active bets earning their place only where a manager demonstrably adds value after fees.

Run the numbers on a ₹25,000 monthly SIP over 20 years at 12% gross. At a 0.10% expense ratio you end with about ₹2.44 crore. At 1.0%, roughly ₹2.16 crore. Same market, same discipline, and about ₹28 lakh quietly redirected from your retirement to the fund house. That gap is the same machinery we covered in regular vs direct plans, just wearing a different label.

Two practical moves. If your index funds charge over 0.2% direct, check whether a cheaper fund tracking the same index with a comparable tracking difference exists; the switch maths usually works if your gains are modest or you can harvest within the LTCG exemption. And if you are still paying 1.5%+ for active funds that hug their benchmark, the widening price gap between closet indexing and real indexing is now impossible to justify.
