SEBI's Credit Risk-o-Meter for bonds: how AAA-to-D ratings map to six colour-coded risk levels on bond platforms and offer documents
SEBI's October 7, 2026 circular makes a six-level colour-coded Credit Risk-o-Meter mandatory on bond offer documents, ads and OBPP screens from November 21, 2026. Here is how it works.
SEBI has given India's bond market a traffic-light system. Under circular HO/17/11/22(1)2026-DDHS-POD1/I/23092/2026, dated October 07, 2026, every offer document, abridged prospectus, private placement memorandum, issuer advertisement and online bond platform provider (OBPP) screen must carry a colour-coded Credit Risk-o-Meter that translates a credit rating into one of six plain-language risk levels. The requirement takes effect 45 days after issuance, which works out to November 21, 2026, leaving 28 days from today (October 24, 2026) for issuers and platforms to comply. The full text is on the SEBI circular page.
This pre-open note sets out what the meter shows, which instruments it covers, how platforms must keep it current, and what a retail bond buyer should check before pressing "invest" from November 21 onward. Nothing here is investment advice; the circular itself requires a disclaimer saying the same.
Market Snapshot
The headline numbers of the new regime fit in one table. Each row below is drawn from the October 07, 2026 circular as summarised in SEBI's own release.
| Parameter | What the circular says |
|---|---|
| Circular date | October 07, 2026 |
| Effective from | 45 days after issuance (November 21, 2026) |
| Number of risk levels | 6, each with its own colour |
| Instruments covered | Listed or to-be-listed NCS, commercial papers, securitised debt instruments, security receipts, market-linked debentures |
| Issue routes covered | Both public issues and private placements |
| Where it must appear | Offer documents, abridged prospectuses, private placement memoranda, issuer and OBPP advertisements, OBPP websites and mobile apps |
| Rating used if multiple | The lowest of the available ratings |
| OBPP update deadline | Within 24 hours of a rating-change intimation from NSDL or CDSL |
| Eligible rating sources | SEBI-registered credit rating agencies only |
| Rule-book change | New Chapter II-C in the NCS Master Circular dated October 15, 2025, and new clause 14 in Annexure-XXIB (OBPP minimum disclosures) |
The six colour bands
The core of the circular is a fixed mapping from long-term and short-term rating symbols to six labelled levels. Long-term symbols (AAA to D) apply to bonds and debentures; short-term symbols (A1+ to D) apply to instruments such as commercial paper.
| Level | Long-term rating | Short-term rating | Risk label | Colour |
|---|---|---|---|---|
| 1 | AAA | A1+ | Lowest credit risk | Irish Green |
| 2 | AA+ to AA- | A1 | Very low credit risk | Chartreuse |
| 3 | A+ to A- | A2 | Low credit risk | Neon Yellow |
| 4 | BBB+ to BBB- | A3 | Moderate credit risk | Caramel |
| 5 | BB+ to BB- | A4+ | Moderate risk of default | Dark Orange |
| 6 | B+ through D | A4, D | High to very high risk of default | Red |
Two features of this table matter for the 3 lower bands. First, the label switches at level 5 from "credit risk" to "risk of default", a deliberate change of wording at the boundary between BBB- (the lowest investment-grade symbol) and BB+. Second, level 6 bundles everything from B+ down to an actual default (D) into a single red band, so a red meter does not by itself tell you whether an issuer has already missed a payment; the rating printed below the meter does.
What sits under the meter
The circular requires 3 pieces of text directly beneath the dial: the name of the credit rating agency, the actual rating symbol, and, for any unsecured instrument, the word "unsecured" in bold red. Where a rating agency has flagged an issuer as "Issuer Not Cooperating", that status must also be shown. For readers new to the distinction, our glossary entries on a secured loan and an unsecured loan explain why the absence of collateral changes recovery prospects in a default.
What Moved Yesterday
For bond investors, the most consequential move of the past fortnight was regulatory rather than a price change. Until the October 07, 2026 circular, a retail buyer on an OBPP saw a rating symbol such as "BBB+" and had to know on their own that it sits 2 notches above the investment-grade floor. From November 21, 2026, the same bond will show a Caramel dial labelled "Moderate credit risk" before the investment button.
Four changes from the old disclosure regime
The table below sets out what shifts for each party. All 4 rows reflect obligations written into the circular.
| Area | Before the circular | From November 21, 2026 |
|---|---|---|
| Rating display | Symbol only (for example, AA-) | Symbol plus colour band plus plain-English label |
| Multiple ratings | Issuer could lead with the best rating | Meter must reflect the lowest rating |
| Unsecured instruments | Disclosed in documents | "Unsecured" in bold red directly under the meter |
| Rating changes on OBPPs | No fixed display-update timeline in Annexure-XXIB | Automated update within 24 hours of NSDL/CDSL intimation, no manual overrides, audit trail required |
The "lowest rating" rule closes a practical gap. Where 2 agencies rate the same debenture AA and A+, the meter will show Neon Yellow (level 3, "Low credit risk"), not Chartreuse (level 2). That is a 1-band difference that a symbol-only display could obscure if a platform led with the higher rating.
Perpetual bonds and the AT1 warning
The circular adds a separate disclaimer for unsecured perpetual bonds, naming Additional Tier 1 (AT1) instruments as an example, stating that they may carry a risk of total loss. This sits in addition to the general disclaimer that applies to every meter. An AT1 bond rated AA would still show a level-2 Chartreuse dial, but the investor would also see a bold red "unsecured" tag and the total-loss warning, so 3 separate signals now appear where previously there was 1 rating symbol.
Advertisements in print and monochrome
The circular anticipates black-and-white media. A monochrome advertisement that cannot reproduce the 6 colours must carry a QR code linking to the colour version of the meter. This applies to all issuer and OBPP advertisements, whether for a public issue or a privately placed instrument offered on a platform.
What to Watch Today
With 28 days until the November 21, 2026 effective date, the things to track over the coming weeks fall into 3 groups: platform readiness, issuer documentation, and investor behaviour.
Platform readiness: the 24-hour clock
OBPPs carry the heaviest operational load. The circular requires them to update the meter within 24 hours of receiving a rating-change intimation from NSDL or CDSL, through an automated system, with no manual overrides and with audit trails. The meter must appear before the investment button, not on a separate details tab. A useful check for any platform you use: after November 21, 2026, open a bond page and confirm that the dial, the rating agency name and the rating symbol are visible on the same screen as the "invest" or "buy" control.
| OBPP obligation | Requirement in the circular |
|---|---|
| Update trigger | Rating-change intimation from NSDL or CDSL |
| Update window | Within 24 hours |
| Method | Automated system |
| Manual overrides | Not permitted |
| Record-keeping | Audit trails required |
| Placement | Before the investment buttons, on web and mobile |
| Rating source | SEBI-registered CRAs only |
Issuer documentation: offer documents and memoranda
Issuers filing offer documents, abridged prospectuses or private placement memoranda after the effective date will need the meter in each document. Because the requirement covers commercial papers, securitised debt instruments, security receipts and market-linked debentures as well as plain NCS, it reaches 5 instrument types, including several that retail investors rarely see on platforms. The broader circular archive is on the SEBI circulars listing.
Investor behaviour: using the meter alongside yield
The meter describes credit risk only. It does not measure interest-rate risk, liquidity or price volatility, which is why SEBI's mandatory disclaimer states that the meter is not investment advice and that debt securities carry market and liquidity risk. A bond yielding several percentage points above a AAA bond will typically sit in a lower colour band; the meter makes that trade-off visible, but the yield to maturity and the coupon rate still decide the cash flows you receive. Our bond yield entry explains how price and yield move in opposite directions.
A worked comparison for a lump-sum buyer
Suppose an investor has Rs 5,00,000 to place in a single corporate bond and is choosing between a level-1 (AAA) issue and a level-4 (BBB) issue. The meter does not change the arithmetic of returns, which an investor can model with the lumpsum calculator using each bond's stated yield. What it changes is the label beside the number: from November 21, 2026, the first option will show Irish Green "Lowest credit risk" and the second Caramel "Moderate credit risk", with the rating agency named on both. Those who prefer to spread exposure over time can compare that with a SIP or a step-up SIP into a debt fund, where the fund manager handles issuer selection.
Five checks before buying a bond after November 21
- Read the colour, then the symbol. The meter shows 1 of 6 bands; the symbol beneath it (for example, AA-) shows where within the band the bond sits.
- Look for the bold red "unsecured" tag. Its presence means no specific asset backs the instrument.
- Check for "Issuer Not Cooperating". This status must be displayed and signals that the rating agency has not received the information it needs from the issuer.
- Confirm the rating agency is SEBI-registered. The circular permits ratings only from SEBI-registered CRAs.
- Read both disclaimers on perpetual bonds. For AT1-type instruments, the total-loss warning appears in addition to the general one.
FAQ
What is SEBI's Credit Risk-o-Meter for debt securities?
It is a colour-coded dial, mandated by SEBI circular HO/17/11/22(1)2026-DDHS-POD1/I/23092/2026 dated October 07, 2026, that converts a credit rating into 1 of 6 risk levels, from "Lowest credit risk" (Irish Green, AAA/A1+) to "High to very high risk of default" (Red, B+ through D).
When does the Credit Risk-o-Meter come into force?
The circular takes effect 45 days after issuance. Counting from October 07, 2026, that is November 21, 2026.
Which instruments must display the meter?
Listed or to-be-listed non-convertible securities, commercial papers, securitised debt instruments, security receipts and market-linked debentures, whether issued publicly or by private placement. That is 5 instrument categories in all.
What happens if a bond has two different ratings?
The meter must reflect the lowest rating. A bond rated AA by one agency and A+ by another would display the level-3 Neon Yellow band ("Low credit risk").
How quickly must bond platforms update the meter after a downgrade?
OBPPs must update it within 24 hours of receiving a rating-change intimation from NSDL or CDSL, using an automated system with no manual overrides and with audit trails.
Does a green meter mean a bond is safe to buy?
No. SEBI requires a disclaimer stating that the meter is not investment advice and that debt securities carry market and liquidity risk. A level-1 rating addresses credit risk only, not interest-rate or liquidity risk.
What extra warning applies to AT1 and other perpetual bonds?
Unsecured perpetual bonds such as AT1 instruments must carry a separate disclaimer that they may carry a risk of total loss, in addition to the general disclaimer and the bold red "unsecured" tag.
