SEBI Specifies 'Significant Indices' — ₹20,000 Crore AUM Threshold, 48 Indices Listed, NSE/BSE/CRISIL Must Register by November 2026

❌ Current Position (the Problem)

Some SEBI-registered entities (e.g., stock exchanges, credit rating agencies, clearing corporations) also provide Significant Indices as a departmental function — i.e., as an internal division rather than a separate legal entity. This creates structural conflicts of interest and blurs regulatory accountability between the entity's primary SEBI-regulated role and its index administration function.

✅ New Requirement

Such entities must form a separate legal entity to carry out Index Provider activities within 2 years from May 5, 2026 — i.e., by May 5, 2028. This structural separation ring-fences index operations from other regulated businesses and eliminates cross-functional conflicts of interest. (Source: SEBI Circular Para 9)

Q1. What exactly is the AUM threshold for an index to qualify as 'Significant'?

Per Para 4 of the circular, a Benchmark or Index is 'Significant' if its daily average cumulative AUM tracked across all domestic mutual fund schemes exceeds ₹20,000 Crore for each of the past six months ending June 30 or December 31. The key word is "each" — the threshold must be sustained every single month of the half-year, not just on average. A temporary spike crossing ₹20,000 Cr is not sufficient; consistent sustained tracking AUM is required. (Source: SEBI Circular Para 4)

Q2. Once on the list, how long before an index can be removed?

An index remains on the Significant Indices list until its cumulative AUM falls below the ₹20,000 Crore threshold for a continuous period of three years — meaning six consecutive half-yearly reviews must all show sub-threshold AUM. A single below-threshold reading does not trigger removal. This stability mechanism prevents compliance churn from temporary market AUM fluctuations. (Source: SEBI Circular Para 5)

Q3. Can NSE Indices / BSE Index Services / CRISIL continue operating while their registration application is pending?

Yes, explicitly. Para 8 of the circular states that any Index Provider providing Significant Indices as on the date of the circular (May 5, 2026) may continue its Index Provider activity during the 6-month application window — provided it submits a registration application to SEBI within those 6 months. There is no disruption to existing indices, fund benchmarks, or market operations during the transition. (Source: SEBI Circular Para 8)

Q4. What happens if an Index Provider misses the November 5, 2026 registration deadline?

The circular does not specify a penalty in this circular itself, but under the SEBI (IP) Regulations, 2024 and the SEBI Act, operating as an unregistered Index Provider after the prescribed period would constitute a violation of the regulations, potentially exposing the provider to action under the SEBI (Intermediaries) Regulations, 2008. SEBI retains broad powers to impose penalties, deregister, or take other action for non-compliance. Index Providers should treat this deadline as non-negotiable.

Q5. Does this circular apply to MSCI India or other global index providers?

Not directly. The IP Regulations — and this circular — apply only to Index Providers administering Significant Indices consisting of securities listed on a recognised Indian stock exchange for use in the Indian securities market. Global providers whose indices consist of global assets, or are used exclusively in foreign jurisdictions, are exempt. However, if a global provider administers India-specific indices that are tracked by domestic mutual funds above the ₹20,000 Crore threshold, those indices would fall within scope.

Q6. As a mutual fund investor in a Nifty 50 index fund — what changes for me practically?

Two practical improvements: (1) Better governance transparency — once NSE Indices registers with SEBI, it must publicly disclose its methodology documents, constituent change information, and maintain a conflict of interest policy and independent oversight committee. This means you will have access to clearer explanations of why stocks are added to or removed from the Nifty 50, and there will be greater checks against opaque or conflicted index decisions. (2) Formal complaint mechanism — if you believe Nifty 50's administration has been unfair or non-compliant, you now have a statutory grievance channel under Regulation 23 of the IP Regulations.

Q7. How is AUM calculated for an index that is used in multiple types of schemes — e.g., both an index fund and a hybrid fund?

For schemes that track multiple indices or benchmarks simultaneously, the AUM is attributed proportionally based on each index's weight in the scheme's overall benchmark. For an index of indices (e.g., a hybrid composite of equity + debt indices), the AUM tracking each underlying index is included in proportion to its weight. This methodology prevents double-counting while ensuring the full economic significance of each index is correctly reflected in its AUM calculation.

Q8. Why are debt and hybrid indices like CRISIL Liquid Overnight or Nifty 1D Rate included alongside equity indices like Nifty 50?

The definition of Significant Indices in the IP Regulations is AUM-agnostic with respect to asset class — it applies to any benchmark tracked by domestic mutual fund schemes exceeding ₹20,000 Crore. Liquid fund and overnight fund categories collectively hold enormous AUM because they are widely used by corporations, institutions, and individuals for short-term cash parking. The CRISIL Liquid Overnight and Nifty 1D Rate indices easily clear the ₹20,000 Crore threshold. Their inclusion recognises that governance failures in debt benchmarks can be just as harmful to investors as governance failures in equity indices — as India learned from the LIBOR manipulation scandal internationally.
