Commercial paper vs NCD: what actually differs

Commercial paper vs NCD looks like a simple short-versus-long comparison until you notice that the letters NCD are doing double duty. Under the Reserve Bank of India's Commercial Paper and Non-Convertible Debentures of original or initial maturity upto one year Directions, 2024, an NCD is a secured money market instrument that matures within a year. Under SEBI's NCS Regulations, 2021, a non-convertible debenture is a listed debt security that may be secured or unsecured and is usually much longer dated. This guide compares commercial paper against both. It is not investment advice.

Which NCD are you talking about?

Start here, because the rest of the comparison depends on it.

The RBI short-term NCD. Paragraph 2(a)(xviii) of the 2024 Directions defines a Non-Convertible Debenture as a secured money market instrument with an original or initial maturity up to one year. Security is not optional in that definition. The instrument sits in the money market alongside commercial paper, is reported to a trade repository rather than filed with an exchange, and is governed by the RBI under sections 45J, 45K, 45L and 45W of the RBI Act, 1934.

The SEBI NCD. The instrument most Indian investors mean by NCD is a listed corporate debenture issued under SEBI's NCS Regulations, 2021, explained in what is an NCD. It can be secured or unsecured, it carries a coupon over multiple years, it is listed on the debt segment of an exchange, and it comes with an offer document and a continuing disclosure regime.

Same acronym. Different regulator, different definition, different data trail. A dataset that stacks both under one label will produce a security-status field that means the opposite thing depending on the row's origin. If you have read the earlier posts on minimum holding period, where the same field name points at RBI guidelines in one disclosure format and SEBI guidelines in another, this is the same failure wearing different clothes.

Commercial paper vs the RBI short-term NCD

Both live in the 2024 Directions, so the differences between them are exact.

Two entries in that table are worth spelling out.

Floating rate. Commercial paper has one pricing mode: a discount to face value. A short-term NCD may also carry a fixed or floating coupon, and where it floats, the benchmark must be published by a Financial Benchmark Administrator or approved by FIMMDA for the purpose, or linked to policy rates published by the RBI.

Settlement. Every over-the-counter secondary trade in commercial paper must settle on a delivery-versus-payment basis through the clearing corporation of a recognised stock exchange, or another RBI-approved mechanism. For short-term NCDs, bilateral settlement is also allowed. The secured instrument has the looser settlement rule, which is the opposite of what most people guess.

What is identical between the two

The 2024 Directions treat commercial paper and short-term NCDs as one market for most purposes, and the shared rules are as informative as the differences:

• Eligible issuers. Companies, NBFCs including HFCs, InvITs and REITs, All India Financial Institutions, any other body corporate with a minimum net worth of one hundred crore rupees permitted to incur debt in India, and any entity the RBI specifically permits. All of them subject to every fund-based facility from banks, AIFIs or NBFCs being classified as Standard at the time of issue.
• Related-party bar. No person, resident or non-resident, may invest in commercial paper or NCDs issued by a related party, in the primary or the secondary market.
• Individual cap. Total subscription by all individuals, including HUFs, may not exceed 25 per cent of the total amount issued in any primary issuance.
• End use. Ordinarily current assets and operating expenses, disclosed in the offer document, with the exact end use disclosed where the money goes anywhere else, and a CEO or CFO certificate to the IPA within 3 months of issue or on maturity if earlier.
• Repayment. No grace period. Funds to the IPA by 3:00 PM on the redemption date.
• Default. Inform the IPA before 5:00 PM on the day of default, report to F-TRAC by 5:30 PM, and no fresh issuance of either instrument until full repayment or six months from the default, whichever is earlier.
• Market hours. 9:00 AM to 5:00 PM on a working day, for primary issuance and secondary trading.

Commercial paper vs the SEBI NCD

Against the instrument most people mean by NCD, the differences are structural rather than technical.

A SEBI NCD is a security issued under an offer document, listed on an exchange, with continuous disclosure obligations and a public trading record. Commercial paper is a money market instrument that in most cases is never listed, whose primary issuance is reported to the F-TRAC trade repository of the Clearing Corporation of India by the issuing and paying agent by 5:30 PM on the day of issuance, and whose secondary trades are reported by both counterparties within 15 minutes. Where commercial paper is listed, Chapter XVII of SEBI's Master Circular dated 15 October 2025 governs what goes to the exchange.

Tenor is the other structural gap. A SEBI NCD has no one-year ceiling, which is why the longer-dated comparison against government and corporate debt sits in NCD vs bond, and why pool-backed instruments get their own treatment in securitised debt instrument vs NCD.

The practical rule: before comparing two instruments called NCDs, check which regulator's definition each one was issued under. Flock reports public regulatory filings with every claim sourced and dated. What any of it means for your money is your call to make.
