Low duration mutual fund
A low duration mutual fund is a SEBI-categorised debt mutual fund scheme that maintains a Macaulay duration of 6 to 12 months. The category was defined under the SEBI October 2017 categorisation framework as one of the 16 debt scheme sub-categories, positioned between ultra short duration funds (3-6 months Macaulay duration) and short duration funds (1-3 years Macaulay duration).
For Indian retail investors, low duration funds offer:
- Short-to-medium horizons (6-18 months): Suitable for deployments where liquid or money-market funds are too short.
- Modest yield premium over money market and liquid funds.
- Low interest-rate sensitivity: Modest NAV reaction to rate changes.
- Good credit quality: Typically AAA/AA+ rated holdings.
This article covers the SEBI category framework, the role in cash management, the major schemes, the comparison with neighbouring categories, and the post-2023 tax treatment.
SEBI category framework

- Macaulay duration of 6 to 12 months at portfolio level.
Macaulay duration is the weighted-average time to receipt of cash flows from the bond portfolio, considering both coupon payments and principal repayment.
Investment universe
Low duration funds invest in:
- Commercial papers (CPs): With 6-12 month residual maturity.
- Certificates of deposit (CDs): With 6-12 month residual maturity.
- Corporate bonds: With residual maturity matching the duration target.
- Government securities and PSU bonds: Selected for duration alignment.
- Money-market instruments: Some allocation for liquidity.

Returns and risk
Typical returns
Low duration funds typically deliver:

Risk profile
- Credit risk: Low (high-quality issuers).

Comparison with neighbouring categories
| Category | Macaulay Duration | Typical Return | Volatility | Suitable For |
|---|---|---|---|---|
| Overnight Fund | 1 day | 4-5% | Negligible | 1 day to 1 week |
| Liquid Fund | Up to 91 days | 4-6% | Very low | 1-3 months |
| Money Market Fund | Up to 365 days | 5-7% | Very low | 3-12 months |
| Ultra Short Duration | 3-6 months | 6-7% | Low | 3-12 months |
| Low Duration | 6-12 months | 6-7.5% | Low | 6-18 months |
| Short Duration | 1-3 years | 6.5-8% | Moderate | 1-3 years |
| Medium Duration | 3-4 years | 7-8.5% | Moderate-high | 3-5 years |
| Long Duration | 7+ years | 7-9% (cyclical) | High | 5+ years |
Tax treatment
Low duration funds are debt-oriented:
- Post-April 2023 framework: All gains taxed at slab rate as short-term capital gains regardless of holding period, per debt mutual fund taxation 2023 .
- Pre-April 2023 purchases: Continue under pre-2023 LTCG treatment with indexation benefit.
The 2023 reform reduced the structural advantage of debt mutual funds (including low duration) over bank FDs and recurring deposits, but the operational efficiency and professional management still offer relative advantages for many investors.
Operational considerations
NAV behaviour
Low duration fund NAV is typically stable with smooth upward drift, with minor day-to-day fluctuations reflecting interest-rate movements.
Exit load
Most low duration funds have zero or minimal exit load. Some may charge 0.10-0.25 per cent on redemptions within 7-30 days.
Cut-off times
Standard 3:00 pm cut-off rule applies (not the earlier 1:30 pm liquid-fund cut-off).
