Low Duration Fund

Where should you park money you might need in roughly a year, without locking it in an FD and without taking on big interest-rate risk? A low duration fund is built for exactly that gap. Under SEBI's mutual fund categorisation, it is a debt scheme whose portfolio carries a Macaulay duration of 6 to 12 months, placing it one notch above ultra-short and liquid funds and below short-duration funds.

What that duration band means

Macaulay duration measures how long, on average, it takes to recover a bond's cash flows, and it is a proxy for sensitivity to interest rates. By keeping it under a year, a low duration fund stays relatively insulated when the RBI shifts the repo rate. When bond prices fell sharply during past rate-hike cycles, longer-duration funds took the hit while this category stayed comparatively steady. The trade-off is modest: you accept somewhat lower upside in a rate-cut rally in exchange for smoother returns.

These funds invest in commercial paper, certificates of deposit, treasury bills and short-maturity corporate bonds. The yield typically beats a savings account and often a liquid fund, which is why investors use them for an emergency buffer, for staging money before a lump-sum equity investment, or for goals 12 to 18 months away.

Risks and tax to weigh

Low *interest-rate* risk does not mean zero risk. Credit risk is real: a low duration fund can still hold lower-rated paper to chase yield, and a default or downgrade can dent NAV. Always check the portfolio's credit quality and the scheme's risk-o-meter before investing, rather than assuming "low duration" equals "safe".

Tax also matters after the 2023 rule change. Gains on debt funds are now taxed at your income-tax slab rate regardless of holding period, removing the old long-term indexation benefit. That narrows the edge over fixed deposits for some investors, so the real case for a low duration fund today rests on liquidity, no lock-in, and steadier-than-FD-flexibility access to your money, rather than on a tax advantage. For conservative savers, it remains a sensible halfway house.
