CRISIL Liquid Index
The CRISIL Liquid Fund Index is the principal Indian benchmark for liquid funds and money-market mutual funds, tracking a basket of short-tenor government securities and high-quality corporate debt instruments. The index is constructed by CRISIL (Credit Rating Information Services of India Limited), India’s largest credit-rating agency and a leading provider of benchmark indices for the Indian debt market.
For Indian retail investors, the CRISIL Liquid Fund Index serves as the standard performance reference for liquid mutual funds. AMCs publish their liquid scheme returns against this benchmark in factsheets and marketing material per TRI benchmarking rules. When evaluating a liquid fund, investors should compare its performance against the CRISIL Liquid Fund Index for fair-context assessment.
Index methodology
Constituent universe
The index covers:
- Treasury Bills (T-Bills): Government of India 91-day, 182-day, 364-day instruments.
- Commercial Paper (CP): Short-term corporate debt (typically AAA-rated, up to 3-month tenor).
- Certificate of Deposit (CD): Short-term bank deposits (typically AAA-equivalent rated, up to 3-month tenor).
- Tri-party Repo (TREPS): Short-term collateralised lending market instruments.
Tenor profile
- Maximum residual maturity: 91 days (matching the SEBI definition of liquid funds).
- Weighted average maturity: Typically 30-60 days.
Weight allocation
The index uses market-cap-weighted methodology:
- Heaviest weight to T-Bills (typically 40-60%).
- Moderate weight to CP / CD (30-40%).
- Smaller weight to TREPS (10-20%).
The exact weights vary based on market conditions and instrument availability.
Rebalancing
The index is rebalanced periodically (typically monthly) to reflect the current short-tenor market.
Role as MF benchmark
Liquid fund benchmarking
Per SEBI requirements and AMFI guidelines, liquid funds must benchmark their performance against:
- CRISIL Liquid Fund Index (most common).
- Or an equivalent index per AMC’s scheme information document.
TRI vs PRI
Unlike equity indices, debt indices like CRISIL Liquid Fund Index inherently include accrued income (since debt returns are primarily income). The “TRI” distinction is less relevant; the index already accounts for total return.
Factsheet disclosure
AMCs disclose:
- Scheme returns vs benchmark over 1, 3, 6, 12 months.
- Year-to-date and since-inception comparison.
- Excess return / underperformance attribution.

Construction philosophy
CRISIL Liquid Fund Index emphasises:
Credit quality
Investment-grade only (AAA / equivalent). Excludes below-AA paper.
Liquidity
Instruments selected are actively traded and liquid.
Replicability
The index is designed to be approximately replicable by a real-money portfolio, so that fund managers can closely track it.
Limitations
Index-tracking gap
In practice, liquid funds may slightly outperform or underperform the index due to:
- Specific instrument selection.
- Cash management decisions.
- TER drag (the index has no TER; the fund does).
Credit-event sensitivity
If a constituent issuer faces credit downgrade or default, the index reflects the loss. Liquid funds typically aim to avoid this by stricter credit selection.
