Securitised debt instrument vs NCD: what differs

By Flock Research · Filings research desk

Securitised debt instrument vs NCD is a comparison of two listed debt instruments that look similar on a screen and are structurally unlike each other. Both pay you from someone else's obligations. The difference is whose. An NCD is a claim on one company. A securitised debt instrument is a claim on a pool of loans or receivables that a company originated and then sold into a trust. Different rulebooks, different credit, different minimum cheque, different disclosures. This comparison sets the two side by side. It is not investment advice.

Definition

The difference between an SDI and an NCD

is what stands behind the payment. An NCD is a corporate debt security repaid by the issuing company from its own cash flows. A securitised debt instrument is issued by a trust and repaid from collections on a ring-fenced pool of debt assigned to that trust.

The credit question is the whole comparison

When you buy an NCD, one balance sheet decides whether you are repaid. You can read that company's financials, its rating rationale, its security cover. If it fails, you are a creditor in its insolvency, ranked by whether your debenture was secured.

When you buy a securitised debt instrument, no single balance sheet decides. Thousands of borrowers do, filtered through a servicer that collects from them and a waterfall that decides who gets paid first. The originator's own health matters less directly, which is the point of assigning the pool to a special purpose distinct entity in the first place. What matters instead is pool composition, seasoning, concentration and the quality of servicing.

That is why the SDI rules carry obligations an NCD has no need for. The originator must retain at least 10 percent of book value, or 5 percent in defined cases, under the minimum retention requirement. It must have held the loans for three or six months by tenor before assigning them, under the minimum holding period. No obligor may exceed 25 percent of the pool at issuance, the pool must be homogeneous, and both originator and obligor need a three-financial-year track record unless the originator is RBI-regulated.

None of that applies to a corporate bond, because a corporate bond has no pool to police.

Who is each instrument actually for?

This is the cleanest practical difference, and it is a rule rather than a market convention.

Regulation 30A sets the minimum ticket size for issuance of a securitised debt instrument at rupees one crore per investor, and holds that floor for subsequent transfers where the originator is not RBI-regulated. An SDI whose underlying is listed securities takes the highest face value among those securities as its transfer floor, and amortising structures may trade below one crore at amortised value as the pool pays down.

NCDs carry no equivalent floor. Public issues of NCDs are routinely sized for retail subscription and trade on the debt segments of the NSE and BSE. So the two instruments do not compete for the same buyer, whatever the screen suggests.

What each tells you after you own it

An NCD issuer keeps reporting as a listed entity: results, material events, and the security cover and trustee obligations attached to the debt itself. What you learn is about a company.

A securitised debt instrument's trustee files a pool disclosure half-yearly, to SEBI and to the stock exchange where the instrument is listed, within 30 days of the end of March or September, under the SEBI circular of 16 December 2025 effective 31 March 2026. What you learn is about a portfolio: maturity buckets, overdue buckets, retention, prepayment, expected credit loss, and for loan-backed pools, rating distribution and security cover. The walkthrough is in how to read an SDI disclosure, and the two prescribed formats differ sharply, as set out in SDI Annexure I vs Annexure II.

Where they genuinely overlap

Both are listed debt, both are rated, both use a trustee to act for holders, and both sit in dematerialised form. Both also carry the same honest caveat as any other credit instrument: a rating is an opinion on default risk at a point in time, not a promise, as explained in what is a credit rating. And in one case they physically overlap, since listed debt securities are themselves a permitted underlying for a securitisation, so an SDI pool can contain NCDs.

Frequently asked questions

Is a securitised debt instrument a type of NCD?

No. They are separate instrument classes under separate rulebooks. An NCD is issued by a company under the SEBI (Issue and Listing of Non-Convertible Securities) Regulations, 2021. A securitised debt instrument is issued by a special purpose distinct entity under the SEBI SDI Regulations, 2008. Source: SEBI.

Who repays a securitised debt instrument versus an NCD?

An NCD is repaid by the issuing company out of its own cash flows, and holders are creditors of that company. A securitised debt instrument is repaid from collections on a ring-fenced pool of loans or receivables held by a trust, so holders depend on the underlying obligors rather than on the originator. Source: SEBI.

What is the minimum investment in each?

A securitised debt instrument carries a minimum ticket size of rupees one crore per investor at issuance under Regulation 30A of the SDI Regulations. NCDs have no equivalent one crore floor for a public issue, which is why they reach retail investors and SDIs generally do not. Source: SEBI.

How often does each disclose after issue?

A securitised debt instrument's trustee files a prescribed pool disclosure half-yearly, within 30 days of the end of March or September, effective 31 March 2026. A listed NCD issuer discloses through the ongoing listing framework for non-convertible securities, including its financial results and material events. Source: SEBI.
