Quick Answer: SEBI's circular of 7 October 2026 mandates a colour-coded Credit Risk-o-Meter on listed debt securities from 21 November 2026. It maps ratings from AAA to D into six colour bands, Irish Green to Red. It shows credit risk only — read it with yield, maturity, security cover and liquidity.

The problem: bonds speak alphabet, buyers need plain words

If you have ever browsed an online bond platform, you have met the alphabet soup: "AA-/Stable", "BBB+(CE)", "A1+". Is AA- much safer than A+? Is BBB+ comfortably investment grade or borderline? SEBI's answer is a mandatory colour-coded Credit Risk-o-Meter for debt securities, issued through a circular dated 7 October 2026. Think of it as a traffic light for bonds: green is lowest credit risk, red is high to very high risk of default, with four shades in between. Issuers of debt securities and Online Bond Platform Providers (OBPPs) — the apps and websites through which many retail investors buy corporate bonds — must display it in offer documents, abridged prospectuses, private placement memorandums, advertisements, and on OBPP web and mobile platforms. The provisions come into force 45 days after the circular was issued: 21 November 2026.

What is SEBI's credit risk-o-meter?

The Credit Risk-o-Meter is a standardised visual gauge mapping a debt security's credit rating to six colour bands. SEBI has fixed exact HTML colour codes for each band, so every platform and printed advertisement shows the same shades. Crucially, the meter represents only credit risk — the likelihood that the issuer fails to pay interest or principal on time. SEBI requires a disclaimer making clear the meter is not investment advice or a recommendation to invest, and that debt investments also carry market and liquidity risks. The framework covers listed and proposed-to-be-listed non-convertible securities, commercial papers, securitised debt instruments, security receipts, and structured debt or market-linked debentures — via public offers or private placements.

The six colours of the credit risk-o-meter, explained

Here is the full translation, from safest to riskiest, as laid down in the circular:
  • Irish Green — Lowest credit risk. Long-term AAA; short-term A1+. The top of the creditworthiness ladder.
  • Chartreuse — Very low credit risk. Long-term AA+, AA, AA-; short-term A1. A notch below the best — still high credit quality.
  • Neon Yellow — Low credit risk. Long-term A+, A, A-; short-term A2. Comfortably investment grade with adequate safety margins.
  • Caramel — Moderate credit risk. Long-term BBB+, BBB, BBB-; short-term A3. The lowest tier still broadly considered investment grade, with thinner safety margins.
  • Dark Orange — Moderate risk of default. Long-term BB+, BB, BB-; short-term A4+. Below investment grade. Note the label change from "credit risk" to "risk of default" — the meter's language gets blunter as you move down the ladder.
  • Red — High to very high risk of default. Long-term B+, B, B-, C and D; short-term A4 and D. Rating D means the issuer has already defaulted on a payment obligation.
Three safeguards sit alongside the colours. First, where more than one agency rates the security, the meter must reflect the lowest rating — no cherry-picking the flattering one, though all ratings may be shown. Second, the agency's name and the actual rating must appear in plain text directly below the meter, so colour never replaces the underlying rating. Third, for unsecured debt, the word "unsecured" must appear in bold red text — because unsecured bondholders are repaid after secured creditors if the issuer runs into trouble.

How do I read the meter before I buy a bond?

Treat the meter as a first filter, not a verdict:
  • Start with the colour, then read the text beneath it. The colour gives the risk band; the agency name and rating beneath it tell you which opinion it is based on.
  • Watch for "Issuer Not Cooperating" (INC). If a rating agency flags the issuer as not cooperating — typically because the company stopped sharing information — the meter points to a separate INC marker instead of a colour band.
  • Check that the meter is current. OBPPs must update the meter within 24 hours of receiving intimation of a rating change, and it must appear prominently on the bond's listing and details pages before you reach the invest buttons.
  • Mind perpetual bonds. For unsecured perpetuals like AT1 bonds, SEBI requires a warning that the meter misses their structural risks — and that such instruments may lose all invested capital.

Why the colour never tells you the yield

This is the single most important thing to understand: a red bond is not automatically a bad bond, and a green bond is not automatically a good one. Yields price risk. A BBB-rated bond offering a higher coupon is not "paying you more for free" — the extra yield is the market's compensation for higher credit risk compared with a AAA bond offering less. A credit rating only signals the issuer's ability to repay — not whether a bond is attractively priced at its current yield. So read the meter alongside yield as a question: is this extra yield enough compensation for this level of default risk? That is a judgement call for your own research — the meter hands you the risk half of the equation, not the answer. The reverse caution also holds: a green bond can still lose you money if you sell before maturity after rates have moved, or if you cannot find a buyer when you need to exit. Colour is credit risk only. Price and liquidity live elsewhere.

What the risk-o-meter does not show: the limits

SEBI requires issuers and OBPPs to state that the meter represents only credit risk. Everything below sits outside its scope:
  • Interest-rate risk. When rates rise, existing bonds with lower coupons fall in price. A AAA-rated long-tenure bond can lose market value even though its default risk is minimal.
  • Liquidity risk. Corporate bonds do not always trade actively. You may not find a buyer at a fair price when you want to sell before maturity.
  • Structural risks. Market-linked debentures and perpetual bonds carry features — principal at risk, call options, coupon deferral — that a credit colour cannot capture.
  • Rating lag. Ratings update periodically. A company under sudden stress may carry a stale rating for weeks before a downgrade; the meter is only as current as the rating behind it.
The meter is a standardised starting point for comparing credit risk across securities — not a complete risk picture.

Bonds vs mutual funds: two meters, different jobs

Mutual fund investors already know the Risk-o-Meter: every scheme must display a six-level gauge from Low to Very High risk, recalibrated monthly based on the portfolio. The new bond meter looks similar but does a narrower job. The mutual fund meter reflects the overall risk of a scheme — combining credit, interest-rate, market and other risks of the whole portfolio. The bond Credit Risk-o-Meter reflects only the credit risk of one debt security. So if a debt fund's scheme meter says "Moderate Risk" while a corporate bond's meter shows Neon Yellow, the two colours are not interchangeable. One is a portfolio-level multi-risk view updated monthly; the other is a single-instrument credit view. Read each in its own lane.
When does the Credit Risk-o-Meter become mandatory?
Where will I see the meter?
What does "Issuer Not Cooperating" mean?
Why must the word "unsecured" appear in bold red?
If two agencies rate the bond differently, which one does the meter use?
Should I never buy a red-meter bond?

Your move: the 7-step bond colour checklist

1. Look at the meter colour on the bond's listing page — it must appear before the invest button from 21 November 2026. 2. Read the credit rating agency's name and the actual rating printed in plain text below the meter. 3. Check for the bold red "unsecured" label and understand it means lower repayment priority. 4. Watch for an "Issuer Not Cooperating" marker — treat it as a signal to investigate further. 5. Read the colour alongside the yield: higher yield is the market's price for higher risk, not a bonus. 6. Check maturity, security cover and liquidity — none of these appear on the meter. 7. Use the meter as a starting filter only; it is not a buy recommendation.
