Credit quality buckets in debt mutual funds
Credit quality buckets categorise debt mutual fund holdings by credit rating, indicating the default risk of each instrument. Indian credit ratings are issued by SEBI-registered Credit Rating Agencies (CRAs): CRISIL, ICRA, CARE, India Ratings, Brickwork. Mutual funds disclose their portfolio composition by credit-quality bucket in monthly factsheets.
Credit rating scale
Standard credit-rating scale (long-term):
| Rating | Interpretation | Default risk |
|---|---|---|
| AAA | Highest credit quality | Negligible |
| AA+ to AA- | High credit quality | Very low |
| A+ to A- | Adequate credit quality | Low |
| BBB+ to BBB- | Moderate credit quality | Moderate |
| BB+ and below | Below investment grade | High (junk) |
| D | Default | In default |
Indian mutual funds primarily hold AAA and AA-rated instruments. AA- and below are typically held only by credit risk mutual funds .
Short-term rating scale
Different scale for instruments maturing within 12 months:
| Rating | Interpretation |
|---|---|
| A1+ | Highest credit quality |
| A1 | High |
| A2 | Adequate |
| A3 | Moderate |
| A4 | Marginal |
| D | Default |
Money market and liquid funds primarily hold A1+ instruments.
Yield-risk trade-off
Higher-rated instruments typically yield less:
| Rating | Approximate yield premium over G-Sec |
|---|---|
| AAA | 50-100 bps |
| AA+ | 100-150 bps |
| AA | 150-200 bps |
| AA- | 200-250 bps |
| A+ | 250-350 bps |
| A | 350-500 bps |
| Below A | 500+ bps |
The credit-spread reflects compensation for default risk.
SEBI credit risk fund framework
Credit risk mutual funds are explicitly defined to invest substantially in below-AAA-rated instruments:
- SEBI requirement: Minimum 65% in below-AAA-rated debt.
- Yield premium: Higher than banking and PSU debt funds .
- Default risk: Higher than typical debt funds.
Use in fund evaluation
Portfolio quality assessment
Investors should check fund factsheets for:
- AAA + sovereign exposure: Higher = lower credit risk.
- Below-AAA exposure: Higher = higher credit risk and yield.
- Issuer concentration: Single-issuer exposure.
Risk-tolerance matching
- Conservative investors: Prefer AAA + sovereign-heavy portfolios.
- Yield-seeking investors: May tolerate AA exposure for additional yield.
- Credit-aware investors: Avoid sub-AAA exposure regardless of yield premium.
Franklin Templeton lessons
The Franklin Templeton April 2020 episode underscored credit-quality importance:
- Funds with high below-AAA exposure faced liquidity stress during the COVID-19 dislocation.
- The episode triggered broader SEBI reforms on debt-fund liquidity and credit disclosure.
