Ultra-short-duration mutual fund

From WebNotes, a public knowledge base. Last updated . Reading time ~9 min.

An ultra-short-duration mutual fund in India is an open-ended debt scheme that must maintain a portfolio Macaulay duration of 3 to 6 months, under SEBI’s October 2017 scheme categorisation circular. This duration band places ultra-short funds between the near-zero duration of liquid funds and overnight funds on one side, and the 6-12 month duration of low-duration funds on the other. Ultra-short funds are commonly used as a higher-return alternative to liquid funds for investors with slightly longer holding horizons (1 to 6 months) who can tolerate marginally more interest rate and credit risk.

Regulatory definition

SEBI circular SEBI/HO/IMD/DF3/CIR/P/2017/114 defined ultra-short-duration funds as:

  • Scheme type: Open-ended ultra-short-term debt scheme.
  • Macaulay duration: 3 to 6 months.
  • Credit quality: No prescribed minimum; fund manager may invest across credit quality within the duration constraint.
  • Benchmark: Typically CRISIL Ultra Short-Term Debt Index.

Portfolio instruments

Ultra-short funds invest in:

  • 3 to 6 month maturity commercial paper (CP) from high-rated companies and NBFCs.
  • 3 to 6 month certificates of deposit (CD) from banks.
  • Short-duration corporate bonds with residual maturity up to approximately 12-18 months (contributing to a portfolio average duration of 3-6 months).
  • Short-dated government securities (T-Bills and cash management bills).
  • TREPS and repo instruments for liquidity management.

Unlike liquid funds (restricted to 91-day maximum maturity), ultra-short funds can hold instruments with maturities beyond 91 days, accepting the additional credit and interest rate risk in exchange for higher coupon yields.

Return characteristics

Ultra-short funds typically generate returns 0.3% to 0.8% above liquid funds on an annualised basis, reflecting the additional duration and credit premiums. Historical returns range from approximately 4.5% to 8.5% per annum depending on the rate cycle.

Unlike liquid funds (which rarely show NAV declines), ultra-short funds may occasionally show negative monthly returns during periods of credit stress or sharp interest rate spikes, though these are typically small and short-lived.

Taxation

Debt-oriented fund; taxed per Finance Act 2023.

For units purchased on or after 1 April 2023: STCG at slab rate regardless of holding period.

For units purchased before 1 April 2023: STCG (under 3 years) at slab; LTCG (3+ years) at 20% with indexation.

Securities Transaction Tax does not apply. See capital gains tax in India and ITR-2 for reporting.

Comparison with adjacent categories

Ultra-short versus liquid fund

Liquid funds are limited to 91-day maturity instruments; ultra-short funds hold 3-6 month duration portfolios. Liquid funds carry a graded exit load for redemptions within 7 days; ultra-short funds typically carry no exit load (or very minimal exit load for very short holding). Liquid funds are safer; ultra-short funds offer marginally higher returns.

Ultra-short versus low-duration fund

Low-duration funds maintain Macaulay duration of 6-12 months, slightly higher than ultra-short (3-6 months). Low-duration funds carry modestly more interest rate and credit risk.

Ultra-short versus money-market fund

Money-market funds invest in money-market instruments with maturity up to 1 year but are focused specifically on money-market instruments (CP, CD, T-Bills). Ultra-short funds may additionally hold short-duration corporate bonds.

Exemplar schemes

  • Kotak Savings Fund (Kotak Mahindra Mutual Fund)
  • SBI Magnum Ultra Short Duration Fund (SBI Mutual Fund)

Suitability

Ultra-short funds are suitable for investors parking idle cash for 1 to 6 months who want slightly higher returns than liquid funds. They are less suitable for investors with very short horizons (overnight to 7 days) or those requiring complete NAV stability.

Regulatory oversight

Regulated by SEBI under the SEBI (Mutual Funds) Regulations, 1996. See mutual fund industry in India.
