What Is the Potential Risk Class Matrix? PRC Cells

The potential risk class matrix is the disclosure that tells you the most risk a debt mutual fund scheme is allowed to take, rather than the risk it happens to be taking today. Every debt scheme is placed in one of nine cells on a 3 by 3 grid: three bands of maximum interest rate risk against three bands of maximum credit risk. It sits alongside the scheme's category and alongside the riskometer, and it answers a different question from either.

How does the potential risk class matrix work?

Paragraph 6.18.1 of SEBI's Master Circular for Mutual Funds requires all debt mutual fund schemes to be classified in terms of a PRC matrix with two parameters: maximum interest rate risk measured by the Macaulay Duration of the scheme, and maximum credit risk measured by its Credit Risk Value.

The bands, from paragraph 6.18.6:

Cross them and you get nine cells, named A-I through C-III. A-I is the most tightly bounded, low duration and high credit quality. C-III is the least bounded on both axes.

The thresholds are ceilings, not targets. Paragraph 6.18.6 is explicit: the thresholds determine the maximum interest rate risk and the maximum credit risk the scheme is permitted to take, but the scheme retains the flexibility to move downwards on the risk scale.

What is Credit Risk Value, and why is a higher number safer?

Because CRV counts quality upward. Paragraph 6.18.8 assigns each instrument a value, and the scheme's CRV is the weighted average across the portfolio, weighted by proportion to AUM:

So Class A, at CRV 12 or more, is roughly an all AAA and sovereign portfolio. Class C, below 10, means the weighted average sits below AA. Macaulay Duration at the scheme level is computed the same way, as a weighted average by proportion to AUM, and the value of a debt instrument used for AUM includes accrued interest, that is the dirty price.

Paragraph 6.18.9 closes a loophole on short term paper: for instruments with short term ratings, the credit risk value is based on the lowest long term rating of an instrument of the same issuer across all rating agencies, and where the issuer has no long term rating, the most conservative long term mapping for that short term rating is used.

What the PRC cell does that the scheme category does not

A scheme category, under the mutual fund scheme categorisation framework, describes what the scheme is for. A PRC cell describes the outer edge of what it may hold. Paragraph 6.18.2 keeps both: AMCs continue to retain the same category for their schemes, and have full flexibility to place single or multiple schemes in any cell of the PRC.

Which means two schemes in the same category can sit in different cells, and the cell is the tighter constraint.

Moving between cells is not a free decision. Under paragraph 6.18.4, once a cell is selected, any change in positioning that results in a risk higher than the maximum specified for the chosen cell, in credit risk or duration terms, is treated as a change in the fundamental attributes of the scheme under regulation 22(9)(c) of the SEBI (Mutual Funds) Regulations, 2026. Fundamental attribute changes carry their own unitholder protections. A move to a lower risk cell does not trigger that.

How are unitholders told?

By SMS and a website link. Paragraph 6.18.5 requires mutual funds to inform unitholders about the classification into one of the nine cells, and about subsequent changes, through SMS and by providing a link on their website referring to the change.

PRC matrix, riskometer, and what each is telling you

They are easy to confuse and they measure different things.

A scheme can hold a conservative portfolio, showing a modest riskometer reading, while sitting in a C-III cell that permits far more. That gap is exactly what the PRC matrix was created to make visible.

One boundary worth stating: mutual funds may invest only in investment grade securities, in terms of regulation 41(1) read with Schedule VI of the SEBI (Mutual Funds) Regulations, 2026. The CRV of 1 for below investment grade paper exists for instruments that fell below the line while held, not for schemes buying there.

What the PRC matrix does not tell you

It does not tell you what a scheme holds, and it does not rank schemes against each other on returns or safety. It is a ceiling disclosure. To see what is actually inside, read the scheme's monthly portfolio statement alongside the cell, and treat any mismatch between the two as the interesting fact rather than a contradiction.

So the potential risk class matrix is a ceiling, disclosed in nine cells, and reading it next to the portfolio is what makes the gap between permitted and actual risk visible.
