Example. A debt fund with a duration of 5 years may fall about 5% if rates rise by 1 percentage point.

Duration measures how much a bond’s price, or a debt fund’s NAV, reacts to a change in interest rates. It’s stated in years. A fund with a duration under a year barely moves when rates change; one with a duration of seven years can move a lot. SEBI uses Macaulay duration to define debt fund categories. See debt funds explained.

Questions people ask

What does duration mean in a debt fund?

Duration tells you how sensitive the fund's bonds are to interest rates, in years. A rough rule: for every 1 percentage point rise in rates, the fund's NAV falls by about its duration in percent, and rises by about as much when rates fall.

Is a higher duration bad?

Not bad, just more sensitive. A long-duration fund gains more when rates fall and loses more when they rise. For money you need soon, a short duration keeps the swings small. SEBI defines several debt fund categories by their Macaulay duration.
