Short Duration Funds
Short duration funds, now officially called Short Term Funds, are debt mutual funds that keep their portfolio's Macaulay duration between one and three years, suiting goals roughly one to three years away.
What Are Short Duration Funds?
A short duration fund is a debt mutual fund that invests in debt and money market instruments such that the Macaulay duration of the portfolio is between 1 year and 3 years.
These funds take more interest rate risk than low duration and ultra-short duration funds, aiming for higher returns over periods of one to three years. They are less sensitive to interest rates than medium or long duration funds.
How Do Short Duration Funds Work?
- Portfolio: The fund holds government securities, bonds of banks, PSUs and companies, and money market instruments.
- Duration band: The manager keeps portfolio Macaulay duration between 1 and 3 years, adjusting within the band based on the interest rate outlook.
- Return sources:
- Accrual: Interest earned on holdings.
- Price changes: When market yields fall, bond prices rise (gains); when yields rise, prices fall (losses).
- Credit choices: Many short duration funds focus on high-rated papers, but some take lower-rated exposure for extra yield. The portfolio and the scheme's potential risk class show this.
- Residual portion: Unlike shorter categories such as liquid, ultra-short and low duration funds, SEBI permits this category to invest its residual portion in InvITs, subject to regulatory ceilings.
Macaulay duration is the weighted average time until the portfolio's cash flows are received. A related figure, modified duration, gives an approximate price sensitivity: price change ≈ −modified duration × change in yield.
Practical Example
Shreya invests ₹5,00,000 for a goal about two and a half years away. Her short duration fund has:
- Macaulay duration: 2.3 years; modified duration: about 2.2 years
- Portfolio yield after expenses: assumed 7.5% a year
If market yields rise by 1 percentage point
- Price impact ≈ −2.2 × 1% = −2.2%
- Value impact ≈ 2.2% × ₹5,00,000 = −₹11,000
If market yields fall by 1 percentage point
- Price impact ≈ +2.2%
- Value impact ≈ +₹11,000
Accrual over one year
- ₹5,00,000 × 7.5% = ₹37,500
Over a year in the rising-rate case, the approximate outcome is ₹37,500 − ₹11,000 = ₹26,500 (about 5.3%). In the falling-rate case, it is ₹37,500 + ₹11,000 = ₹48,500 (about 9.7%). This shows why returns from short duration funds can vary noticeably year to year, and why matching your horizon to the fund's duration helps.
Why Are Short Duration Funds Important?
- Medium-short goals: Can fit goals one to three years away, such as a vehicle purchase or a planned course fee.
- Interest rate sensitivity is meaningful: NAV can fall over a few months when rates rise.
- Portfolio quality differs: Credit risk can vary significantly between schemes.
- Tax: These funds invest more than 65% in debt and money market instruments, so they are "specified mutual funds". For units bought on or after 1 April 2023, gains are taxed at your slab rate regardless of holding period. Units bought earlier follow older rules. Check the latest Income Tax rules or consult a tax adviser.

Comparison With Related Concepts
| Category (official name) | Duration rule | Key difference | Practical implication |
|---|---|---|---|
| Ultra Short to Short Term Fund (low duration) | 6–12 months | Lower rate sensitivity | Goals about a year away |
| Short Term Fund (short duration) | 1–3 years | Moderate rate sensitivity | Goals 1–3 years away |
| Medium Term Fund (medium duration) | 3–4 years | Higher rate sensitivity | Longer horizons, more volatility |
| Corporate Bond Fund | 80%+ in AA+ and above corporate bonds; no duration band | Defined by credit quality | Duration varies by scheme |
| Banking & PSU Fund | 80%+ in bank, PSU, PFI and municipal debt | Defined by issuer type | Duration varies by scheme |
How Do Short Duration Funds Apply to Mutual Fund Investors?
- Match your horizon: Ideally hold for at least the fund's Macaulay duration.
- Check the factsheet: Look at Macaulay duration, modified duration, yield to maturity, average maturity and rating breakdown.
- Understand the potential risk class: AMCs disclose a matrix of interest rate and credit risk that helps compare schemes.
- Watch the name change: Schemes in this category may now be named "Short Term Fund".
- Consider SWP or STP: Some investors use a Systematic Withdrawal Plan (SWP) for planned withdrawals, or an STP to move money into other funds gradually.
Common Mistakes and Misconceptions
- "Short duration means very low risk, like a liquid fund." Correct view: a 1–3 year duration means noticeable NAV movement when rates change. Why it matters: short holding periods can show losses.
- "Debt funds always give positive returns." Correct view: rate rises and credit events can cause negative returns over some periods. Why it matters: debt funds are market-linked, not fixed deposits.
- "Short Term Fund is a new category." Correct view: it is the new official name of the short duration category, with the same 1–3 year band. Why it matters: avoid confusion when comparing old and new scheme names.
- "Holding for three years gives lower tax." Correct view: for units bought from 1 April 2023, gains are taxed at slab rates regardless of holding period. Why it matters: compare post-tax returns with alternatives.
- "Higher yield means a better fund." Correct view: higher yield often reflects higher credit or duration risk. Why it matters: look at the portfolio, not just the yield figure.

Frequently Asked Questions
What is the duration rule for short duration funds?
SEBI requires the portfolio's Macaulay duration to be between one and three years. The fund invests in debt and money market instruments and can adjust its duration within this band depending on the fund manager's interest rate view.
Why is the category now called Short Term Fund?
SEBI's circular dated 26 February 2026 standardised debt category names, renaming "short duration" to "Short Term Fund" while keeping the 1–3 year Macaulay duration band. Existing schemes had six months to align names and parameters, and these changes were not treated as fundamental attribute changes.
Can short duration funds lose money?
Yes. If interest rates rise, bond prices fall and the NAV can decline, especially over short periods. Credit downgrades or defaults can also cause losses. Over holding periods matching the fund's duration, interest accrual tends to offset rate-driven price falls, though this is not guaranteed.
How long should I invest in a short duration fund?
A horizon of roughly one to three years, or at least the portfolio's Macaulay duration, is generally appropriate. For money needed sooner, liquid, money market or ultra-short categories may be more suitable.
How are short duration funds taxed?
They are specified mutual funds because they invest more than 65% in debt and money market instruments. For units bought on or after 1 April 2023, gains are taxed at your slab rate regardless of holding period. Units bought earlier follow different rules. Check the latest Income Tax rules or consult a tax adviser.
How are short duration funds different from corporate bond funds?
Short duration funds are defined by a 1–3 year Macaulay duration band and can hold different types of issuers. Corporate bond funds must invest at least 80% in corporate bonds rated AA+ and above, with no fixed duration band. One is defined by duration, the other by credit quality.
