sebi s mutual fund reforms new expense ratio rules lower fee caps and the impact on amcs
On 17 December 2025, the Securities and Exchange Board of India (SEBI) announced a set of far-reaching mutual fund reforms that go beyond routine regulatory fine-tuning. These changes alter how mutual fund expense ratios are defined, capped, and disclosed, and they directly affect both investor returns and AMC business models.
Unlike earlier TER tweaks, the SEBI mutual fund reforms 2025 focus on structural clarity. The regulator wants investors to clearly understand what portion of their cost goes to the AMC, and what portion is simply taxes or market-related charges. At the same time, SEBI has tightened fee ceilings across categories, increasing cost pressure on fund houses.
The December 2025 reform introduces a clearer framework for mutual fund expenses by separating core AMC fees from statutory and transaction-linked charges. Earlier, investors saw a single Total Expense Ratio (TER), which bundled everything together. This made comparisons difficult and often masked the true cost of fund management.
SEBI’s revised structure brings transparency by redefining how expense ratios are calculated and reported, while also lowering permissible fee limits in several fund categories.
The most important concept introduced by SEBI is the Base Expense Ratio (BER).
BER represents the actual fee charged by the AMC to run the mutual fund. It includes fund management costs, administrative expenses, and investment infrastructure, but excludes taxes and statutory levies. Under the new framework, TER is no longer a single opaque number.
Instead, TER is now the sum of the BER plus brokerage costs, regulatory charges, and statutory levies such as GST, STT, and stamp duty. These levies are charged on actuals rather than being embedded inside a capped expense ratio.
This distinction between TER vs BER makes it easier for investors to compare funds and understand whether they are paying higher fees because of the AMC’s cost structure or simply due to unavoidable taxes.
Earlier, two funds with similar TERs could have very different cost structures. One AMC might be charging a higher management fee, while another might simply be incurring higher transaction costs. Investors had no easy way to tell the difference.
With BER now disclosed separately, investors can clearly see how much they are paying the fund house itself. This directly improves transparency and addresses long-standing concerns around mutual fund cost opacity in India.
Along with redefining expense components, SEBI also reduced expense ratio caps across multiple mutual fund categories. While the exact reduction varies by scheme type, several categories have seen fee ceilings lowered by roughly 10 to 15 basis points.
This is particularly meaningful for index funds, ETFs, close-ended schemes, and certain fund-of-fund structures, where scale and efficiency are expected to translate into lower costs for investors. Over long holding periods, even a small reduction in expense ratio can materially improve net returns.
Example Impact: A 20 basis point reduction on a ₹10 lakh portfolio over 20 years can result in approximately ₹2.95 lakh of additional wealth.
For Asset Management Companies, these reforms represent a margin reset.
Lower BER caps reduce the revenue AMCs earn per unit of AUM. At scale, even a small reduction in expense ratio has a meaningful impact on profitability. As a result, AMC growth can no longer rely on pricing power alone.
Instead, AMCs must focus on expanding assets under management, improving operational efficiency, and delivering consistent performance. Cost structures are likely to come under scrutiny, with greater emphasis on automation, technology-driven servicing, and rationalization of overlapping schemes.
The reforms also accelerate an industry shift toward volume-led and efficiency-led growth. Passive products such as index funds and ETFs become even more cost-competitive for investors, but margins for AMCs shrink further. Only fund houses with scale or differentiated offerings are likely to thrive.
Execution quality becomes a competitive advantage. With tighter brokerage allowances, AMCs that can deliver alpha after costs will stand out more clearly, while high-churn strategies may find it harder to justify themselves.
Investors should start paying closer attention to BER and TER disclosures as AMCs update their reporting. High-cost funds without consistent alpha deserve closer scrutiny, especially now that cost transparency has improved.
Comparing direct mutual fund expense ratios and focusing on process-driven investing rather than product hype becomes even more important in this new regulatory environment.
Q1) What changed in SEBI mutual fund rules in 2025?
Ans: SEBI introduced the Base Expense Ratio (BER), separated statutory levies from TER, reduced expense caps, and tightened brokerage disclosures.
Q2) What is BER in mutual funds?
Ans: BER is the core fee charged by the AMC, excluding taxes and transaction-linked statutory levies.
Q3) Will mutual fund costs go down after SEBI reforms?
Ans: In many categories, yes. Reported reductions are around 10–15 basis points, depending on the scheme.
Q4) How do SEBI reforms affect mutual fund AMCs?
Ans: AMCs face margin pressure, pushing them toward efficiency, scale, and performance-led growth.
The SEBI mutual fund reforms announced on 17 December 2025 mark a clear shift toward transparency, efficiency, and investor-first regulation. Investors benefit from clearer cost disclosures and lower expenses, while AMCs are nudged toward sustainable, performance-driven business models.
Over time, these reforms should strengthen trust in mutual funds and improve long-term outcomes for Indian investors.
