Municipal debt securities vs NCD
Municipal debt securities vs NCD is a comparison between two SEBI rulebooks that produce superficially similar instruments: listed, non-convertible, rated, trustee-monitored debt. What differs is what stands behind the money. A non-convertible debenture is a claim on a company, backed where secured by a charge on its assets. A municipal debt security is a claim on a civic body, and what protects the holder is a mandated escrow structure over earmarked revenue rather than a charge on a city's assets. This guide sets the two frameworks side by side. It is not investment advice.
Definition
The municipal debt securities vs NCD difference
is regulatory and structural. Municipal debt securities are issued under the SEBI (Issue and Listing of Municipal Debt Securities) Regulations, 2015 by municipalities and comparable statutory bodies, with debt servicing routed through mandated escrow accounts. NCDs are issued under the SEBI NCS Regulations, 2021 by companies, secured where applicable by a charge on assets. Source: SEBI.
Who can issue, and what is the eligibility test?
An NCD is issued by a company. The issuer's disclosure obligations, security cover and trustee arrangements follow from the NCS Regulations, 2021, and the instrument is explained in what is an NCD.
A municipal debt security is issued by a municipality constituted under Article 243Q of the Constitution, or by any Statutory Body, Board, corporation, Authority, Trust or Agency established or notified by a Central or State Act, or by a Special Purpose Vehicle notified by a government, provided the entity performs a function entrusted under Article 243W. Structures under the Pooled Finance Development Fund Scheme are deemed issuers too. The full picture is in what are municipal debt securities.
The eligibility tests are where the two diverge first. Regulation 4 of the municipal framework requires the issuer to be entitled to borrow under its constitution document, to keep accounts under the National Municipal Accounts Manual or an equivalent, and to have no default in repayment of debt securities or of bank or financial institution loans in the preceding three hundred and sixty five days. For a public issue, Regulation 5 adds surplus income in any of the immediately preceding three financial years, or, for a body corporate issuer, no negative net worth in those years.
That surplus income test has no counterpart in corporate debt issuance. It is a solvency screen written for an entity that does not have a profit and loss statement in the ordinary sense.

The security question: charge versus escrow
This is the substantive difference, and it is easy to get backwards.
A secured NCD is backed by a charge on identified assets of the issuer, and SEBI requires secured debt securities to maintain security cover of 100 per cent of the outstanding amount. If the company defaults, the trustee enforces against those assets.
A municipal debt security is not built that way, and since 2019 it is explicitly not built that way. The pre-2019 Regulation 19 required debentures to be secured by a charge on properties, assets or receivables of the issuer with a value sufficient for repayment, and the pre-2019 Regulation 16 required 100 per cent asset cover at all times. Both were substituted by the amendment effective 27 September 2019. What replaced Regulation 19 is a single sentence: the issuer shall create a structured payment mechanism and maintain specific escrow accounts for the purpose of debt servicing of the municipal debt securities as specified by the Board from time to time.
The definitions clause names the accounts that mechanism uses. A no lien escrow account for receiving and disbursing funds towards contractual obligations. An interest payment account for interest that falls due. A sinking fund account created specifically for repayment. Under Regulation 26(3), monitoring the escrow account holding earmarked revenue is a duty of the debenture trustee.
The logic is straightforward once you see it. Enforcing a charge against a city's assets is not a realistic remedy. Ring-fencing a stream of civic revenue before it reaches the general budget is.
What each one discloses after issue
For an NCD, continuing disclosure runs through the listed-debt regime and the trustee's reporting.
For a municipal debt security, Regulation 23 requires compliance with the listing conditions in Schedule V of the regulations, which is a short list of periodic disclosures: material adverse changes affecting the ability to service bonds, proposals for prepayment and valuation on sale or purchase before maturity, key ratios such as debt equity, debt service coverage and interest service coverage, and a half yearly return on servicing of bonds, credit enhancement facilities and investor grievances and redressal. Any change in rating is disseminated promptly, and the issuer, trustee and exchanges all put the information on their websites. The full walkthrough is in how to read a municipal bond disclosure.
Note what Schedule V is built around: project delivery and debt servicing capacity, not quarterly earnings. That is the difference between lending to an operating company and lending against a defined civic revenue stream.
Where the two frameworks meet
They share more plumbing than the separate rulebooks suggest. SEBI's Master Circular for issue and listing of non-convertible securities, securitised debt instruments, security receipts, municipal debt securities and commercial paper, dated 15 October 2025, is a single document covering all of them. Its Chapter I applies the ASBA and UPI application process to public issues under the NCS, municipal and securitised debt rulebooks alike. Its Chapter VI now puts both instruments under the same Electronic Book Provider mandate: a private placement of debt securities, NCRPS or municipal debt securities of Rs 20 crore or more must be bid on the platform, a threshold that was Rs 50 crore and excluded municipal debt securities until a SEBI circular dated 16 May 2025. See what is the Electronic Book Provider platform.
If you are mapping the broader listed-debt landscape, the longer-dated comparison sits in NCD vs bond, and the pool-backed instrument that shares none of this structure is covered in securitised debt instrument vs NCD.
Two listed non-convertible instruments, two rulebooks, and one real difference: whether the protection is a charge you can enforce or a cash flow you can ring-fence. Flock reports public regulatory filings with every claim sourced and dated. What any of it means for your money is your call to make.
Frequently asked questions
Are municipal bonds and NCDs governed by the same SEBI rules?
No. Municipal debt securities are issued and listed under the SEBI (Issue and Listing of Municipal Debt Securities) Regulations, 2015. Non-convertible debentures are issued and listed under the SEBI (Issue and Listing of Non-Convertible Securities) Regulations, 2021. Both are non-convertible listed debt, but the eligibility tests, security structure and periodic disclosures differ. Source: SEBI.
What secures a municipal debt security?
A payment structure rather than a charge on assets. Regulation 19 requires the issuer to create a structured payment mechanism and maintain specific escrow accounts for debt servicing. The pre-2019 version of the framework required a charge on assets or receivables and 100 per cent asset cover, and both of those provisions were substituted in 2019. Source: SEBI ILMDS Regulations, 2015.
Is listing mandatory for municipal debt securities?
Yes. Regulation 4E requires the issuer to apply for listing to one or more recognised stock exchanges, and where listing or trading permission is not obtained, the money is refunded. That applies to public issues and to private placements intended to be listed, which is the scope of the regulations under Regulation 3. Source: SEBI ILMDS Regulations, 2015.
How much must a municipal issuer contribute to the project itself?
Not less than twenty per cent of project costs for each issuance, from internal resources or grants, in cash or in kind, under Regulation 18B. There is no equivalent own-contribution floor for a corporate NCD issuer, whose use of proceeds is disclosed in the offer document but not matched by a mandated equity share of the project.
