2.4.3 Other Debt Categories
Beyond the duration-based ladder, debt funds are also categorised by what they invest in: corporate bonds, credit risk, banking and PSU debt, gilts, or a dynamic mix that shifts based on the manager's view.
Categories built around what is held, not just when it matures
A corporate bond fund must primarily hold high-quality corporate bonds. A credit risk fund deliberately takes on lower-rated, higher-yielding corporate debt in pursuit of extra return. A banking and PSU fund concentrates on debt issued by banks and public sector undertakings, generally considered relatively stable issuers. A gilt fund holds only government securities.
Beyond the duration-based classification, SEBI defines several debt fund categories based on what the fund holds rather than how long it holds. Banking and PSU funds invest at least 80% in debt instruments of banks, public sector undertakings and public financial institutions. Corporate bond funds invest at least 80% in AA+ and above rated corporate bonds. Credit risk funds invest at least 65% in below-AA rated instruments. Gilt funds invest at least 80% in government securities across maturities. Gilt with 10-year constant duration funds maintain a portfolio duration of approximately 10 years in government securities.
Each of these categories carries a different primary risk. Banking and PSU funds have low credit risk (the issuers are typically high-quality) but varying interest rate risk depending on portfolio maturity. Corporate bond funds accept modest credit risk for a yield pickup over government securities. Credit risk funds take on significant credit risk in exchange for higher yield. Understanding which risk the fund is primarily taking is essential for matching it to your allocation needs and risk tolerance.
Dynamic and target maturity structures
A dynamic bond fund gives the manager freedom to actively shift duration based on their own interest-rate outlook, taking on the added risk that this active call could turn out wrong. A target maturity fund does the opposite, holding a defined basket of bonds that all mature around a specific future date, giving investors a fairly predictable, bond-like outcome if held to that date.
Dynamic bond funds have the flexibility to change portfolio duration based on the fund manager's interest rate view, shifting between short and long duration as the rate outlook evolves. When the manager is right, this produces superior returns. When wrong, the fund can underperform both ends of the duration ladder. Target maturity funds offer a more passive alternative: they hold bonds maturing around a fixed date and allow the portfolio to naturally reduce in duration as the target date approaches, providing predictable return outcomes for investors who hold to maturity.
Floater funds invest primarily in floating-rate instruments whose coupons reset periodically with market rates. These carry minimal interest rate risk because the coupon adjusts to the current rate environment, but they still carry credit risk based on the issuer quality. In a rising rate environment, floaters outperform fixed-rate debt because their coupons increase with rates. In a falling rate environment, they underperform because coupons decline.
Reading the category name carefully
These category names describe genuinely different risk profiles, even among funds nominally in the same broad duration bracket. A credit risk fund and a gilt fund can carry similar interest-rate exposure while carrying very different levels of default risk, which is exactly the kind of distinction the category label is designed to surface.
How PriLytics helps. PriLytics reveals the actual composition behind every debt fund you hold, so category labels are backed by the real underlying picture. See your true asset allocation.
When choosing a debt fund category, start with the risk you are comfortable taking (credit risk, interest rate risk, or both) and match it to the category definition. If you want minimal credit risk, stick to gilt, banking and PSU, or corporate bond funds. If you want minimal interest rate risk, choose overnight, liquid, ultra-short, or floater funds. If you are willing to take credit risk for higher yield, understand that credit risk funds can and do experience defaults and downgrades that produce sudden, sharp NAV declines. The category name is a risk disclosure; read it as one.
