The structure of mutual funds in India has three main tiers: sponsor, trustees and AMC. SEBI regulates the industry, while AMFI supports industry practices. Custodians hold scheme securities, and RTAs manage investor records and transactions. Each entity has a separate role in how mutual funds are set up, managed, and monitored.
Mutual funds in India are not managed by just one entity. Their structure separates different responsibilities across sponsors, trustees, AMCs, custodians, and RTAs, while SEBI regulates the overall industry.
Understanding the structure of mutual funds in India can help you see who manages your money, who keeps the assets safe, and who checks whether the rules are being followed.

Structure of Mutual Funds in India: A Simple Breakdown
As per SEBI regulations, the structure of mutual funds in India follows a 3-tier format:
- Sponsor
- Trustees
- AMCs
Let’s first understand the specific roles and responsibilities of each tier before we cover the essentials of what is SEBI, full form of AMFI, and the role of custodians:
1st Tier: Sponsor
A mutual fund sponsor is the entity that sets up the fund in question. A fund can have one or multiple sponsors. Its role includes:
- Bringing capital to create a public trust under the Indian Trusts Act of 1882.
- Registering the trust with SEBI and seeking required approvals.
- Establishing the AMC and appointing the trustees.
As per SEBI regulations, sponsors are required to contribute at least 40% of the AMC’s net worth and meet other eligibility requirements set by the market regulator.
2nd Tier: Trustees
After the sponsor creates the trust with a legal trust deed, they have to appoint trustees (as per SEBI’s eligibility and approval rules). Their primary role is to function as the watchdog of the fund to safeguard investors’ interests.
Trustees in mutual funds play the following roles:
- Protecting investor interests.
- Supervising the AMC’s activities.
- Checking compliance with SEBI regulations.
- Submitting reports on AMC operations, non-compliance, and corrective action to SEBI.
According to SEBI regulations, each mutual fund must have at least 4 trustees or appoint a trustee company with at least 4 directors.
3rd Tier: AMC
Now comes the last ‘main’ tier - the AMC. The full form of AMC is Asset Management Company. It is the company appointed to actually run the mutual fund and manage the money collected under its schemes.
In India, AMCs function under SEBI’s mutual fund regulations and work under the oversight of the trustees. AMCs have their own team of fund managers, research teams, operations staff, and compliance teams to perform the following roles:
- Launching mutual fund schemes
- Managing scheme portfolios
- Making investment decisions
- Following SEBI regulations
- Publishing NAVs and disclosures
- Handling investor service requests
Understanding the Other Key Players
Now that you know all about the overarching structure of mutual funds in India, let’s dive into what is SEBI, AMFI, custodian, and RTA in this structure and the roles they play:
Entity | What It Is | Key Role |
SEBI | The Securities and Exchange Board of India is the main regulator of India’s securities market. |
|
AMFI | AMFI’s full form is Association of Mutual Funds in India. It is the non-profit SRO (self-regulatory organisation) of all SEBI-registered asset management companies that focuses on the ethical growth of the industry. Unlike SEBI, it does not regulate the industry. |
|
Custodian | A custodian is an independent entity responsible for safely storing the securities owned by the scheme. |
|
RTA | A Registrar and Transfer Agent manages investor records and transaction-related administration for mutual funds. |
|
Conclusion
A simple way to think about the structure of mutual funds in India is: the sponsor sets up the mutual fund, the trustees supervise it, and the AMC works to manage the schemes and investments.
Around these three main tiers, SEBI regulates the industry, AMFI supports industry-wide practices, custodians hold scheme assets, and RTAs manage investor records and transactions. Together, these entities help ensure mutual funds operate smoothly and within the required regulatory framework.
