2.4.2 Debt Fund Categories by Duration
Debt funds are categorised primarily by duration, from overnight funds holding for a single day to long duration funds holding bonds maturing many years out. Duration is the single biggest driver of a debt fund's risk profile.
The duration ladder
Overnight and liquid funds hold extremely short-term instruments and are built for capital safety and near-instant access. Ultra-short, low duration and money market funds extend that horizon slightly. Short, medium and medium-to-long duration funds progressively extend maturity further, and long duration funds hold the longest-dated bonds of all, taking on the most interest-rate sensitivity in exchange for typically higher yields.
Why this ladder exists
Regulators created these standardised categories specifically so investors could reasonably compare funds with similar risk profiles against each other, and so that a fund's name gives a genuine signal about the interest-rate risk it is likely to carry, rather than requiring every investor to dig through a full portfolio breakdown just to understand basic risk positioning.
Matching duration to your own need
The category that suits you should follow directly from when you actually need the money, not from which category happens to be offering the highest current yield. Money needed within a year belongs near the short end of this ladder regardless of how attractive a longer duration fund's yield looks in isolation.
How PriLytics helps. PriLytics shows the true duration and category profile behind every debt fund you hold, so your risk exposure is visible rather than hidden behind a fund's name alone. See your true asset allocation.
