Understanding NDS-OM: SEBI's Framework for Government Securities Trading

SEBI’s NDS-OM Framework: A New Gateway to Government Securities for Retail Investors

In a quiet but significant shift, the Securities and Exchange Board of India (SEBI) has opened the door for stock brokers to facilitate trading on the Negotiated Dealing System-Order Matching (NDS-OM) platform. This move could reshape how retail investors participate in the government securities (G-Sec) market—long considered the domain of institutional players.

Announced through a circular on February 11, 2025, SEBI’s new regulatory framework allows registered brokers to access the NDS-OM platform by establishing a Separate Business Unit (SBU) within their firms. The aim? To bring greater transparency, efficiency, and inclusivity to India’s government bond market.

First, What Is NDS-OM?

The NDS-OM platform, maintained by the Reserve Bank of India (RBI), is a fully electronic, order-driven system for trading government securities in the secondary market. It enables real-time matching of buy and sell orders, fostering a more transparent and liquid market.

Until now, participation was largely restricted to institutions with direct RBI access. That’s beginning to change—with SEBI’s new framework designed to broaden access for retail investors through brokers.

SEBI’s Role—and Its Limits

While SEBI is facilitating this transition, it's important to note that all trading activities on the NDS-OM platform fall under the jurisdiction of the RBI, not SEBI. This distinction is central to the new structure—and to the investor safeguards that SEBI has outlined.

The Structural Safeguards: SEBI’s Conditions for Brokers

To ensure that NDS-OM participation does not create conflicts or systemic risks, SEBI has laid out a series of conditions that every SBU must follow.

1. Operational Segregation

The SBU must be completely ring-fenced from the broker’s other securities market operations. It is not a department within the firm—it must function like a separate entity with its own identity.

2. Single-Market Focus

The SBU’s role is strictly limited: it may only participate in transactions on the NDS-OM platform. It is not permitted to undertake any other activities in the securities market.

3. Independent Accounting

Each SBU must maintain its own set of books—separate from the broker’s main financial accounts. All transactions and financial dealings must comply with arm’s-length principles, ensuring independence from the parent entity.

4. Net Worth Carve-Out

The SBU’s net worth is treated independently from that of the broker. When evaluating a broker’s compliance with SEBI’s capital adequacy rules, the SBU’s finances are excluded. This ensures that exposure in one business line doesn’t mask risk elsewhere.

No SEBI Grievance Redressal: What Investors Should Know

Retail investors accessing government securities through these broker-linked SBUs should note that SEBI’s grievance redressal mechanisms—like SCORES or the Investor Protection Fund (IPF)—do not apply to NDS-OM trades.

Oversight Instead Lies with the RBI

This includes responsibility for:

• Policy formulation
• Investor complaints
• Risk management oversight
• Regulatory inspections
• Enforcement actions

For any issue arising from NDS-OM activity, investors would need to approach RBI or the designated market intermediaries, not SEBI.

Why This Matters: Industry Reactions

Ajay Garg, CEO of SMC Global Securities, welcomed the move, highlighting that it could go a long way in bringing retail investors closer to a relatively underexplored segment of the fixed-income market.

Garg noted three immediate benefits:

• Simplified participation: Investors can now place orders via brokers, just like in equity markets.
• Deeper liquidity: More participants mean a more dynamic and accessible secondary market.
• Broader financial inclusion: For brokers, this opens up new avenues to serve a wider investor base.

Summary Table: SEBI’s SBU Safeguards for NDS-OM

Safeguard	Description
Segregation & Ring-Fencing	SBU operations must remain distinct from the broker’s other business activities
Exclusive Engagement	SBU is restricted to NDS-OM transactions only
Separate Accounting	Independent financial records required for SBU
Net Worth Segregation	SBU’s net worth excluded from broker’s regulatory net worth calculations
Grievance Redressal	SEBI’s SCORES/IPF not applicable; RBI oversight in effect

Conclusion

At its core, SEBI’s framework reflects a thoughtful effort to open up government securities to everyday investors, without compromising on regulatory rigor or operational safeguards. While RBI will continue to oversee the actual trading activity, SEBI has ensured that any broker facilitating access to NDS-OM does so within a well-defined, firewalled structure.

As more retail investors begin exploring fixed-income options beyond bank deposits and small savings schemes, this could mark the start of a more inclusive, diversified bond market in India—one where transparency, simplicity, and risk containment go hand-in-hand
