MUMBAI: The Securities and Exchange Board of India (Sebi) has proposed a financial threshold to determine which market indices will fall under its regulatory oversight. In a consultation paper released on Monday, the regulator said any index tracked or used as a benchmark by domestic mutual fund schemes with cumulative assets under management (AUM) of more than ₹20,000 crore will be designated a “significant index” and brought under the Index Provider Regulations introduced in 2024. The proposal is aimed at improving transparency and accountability in the governance and administration of indices, Sebi said.
