Debt mutual funds: liquid, gilt, and target maturity.
Two dials — credit risk and rate risk — define every debt fund you choose.
The RBI hiked rates. His 'safe' fund's NAV fell 8%.
Ramesh retired last year. His bank offered him a fixed deposit. His nephew suggested a debt mutual fund instead — 'same returns, more flexible.' Three months later, the RBI hiked interest rates. Ramesh's fund NAV dropped. He called his nephew: 'You said this was safe.' Nobody had explained the difference.
A debt fund pools money from investors and lends it to the Government of India, banks, and large companies. Each borrower issues a bond — a promise to repay with interest on a fixed date. The fund earns that interest and passes it to you as returns. The first risk dial is credit risk: will the borrower repay? Government bonds carry zero default risk. Corporate bonds carry more. Funds chasing higher yields often hold lower-rated bonds — and in April 2020, Franklin Templeton India wound up six debt schemes, trapping approximately ₹25,000 crore of investor money due to credit risk concentration.
The second dial is interest rate risk. When the RBI raises rates, prices of existing bonds fall. Here's why: if you hold a bond paying 6.5% and new bonds now pay 7.5%, yours is less attractive. Its price drops until its effective yield matches the market. A long-duration gilt fund can lose 10–15% of its NAV during a rate-hike cycle. That is not a default — the money comes back at maturity. But it is a real loss if you sell early.
SEBI has mandated 16 debt fund categories, each with strict maturity limits. Liquid funds must invest only in instruments maturing within 91 days — a smarter savings account, redeemable any day. Ultra-short duration funds suit 3–12 month horizons. Gilt funds lend exclusively to the Government of India — zero default risk, but the highest rate sensitivity. Target maturity funds hold bonds until a fixed date and become less volatile as maturity approaches.
The Finance Act 2023 changed the tax rules for debt funds bought after April 1, 2023. Gains are now taxed at your income slab rate, regardless of how long you hold. The indexation benefit and lower long-term rate no longer exist. Debt funds and FDs are now taxed identically.
The neighbour who reprices your bonds daily
Imagine a neighbour who knocks on your door every morning with an offer to buy your bond. When the RBI is calm, he's cheerful and pays a fair price. When rates rise, he turns anxious and slashes his offer by 10%. If you must sell, you accept his bad-day price. If you can hold until the bond matures, the borrower repays you in full — Mr. Market's mood was just noise. The trick with debt funds is knowing whether you can afford to wait.
Why this matters
The right debt fund depends on when you need the money. For your emergency fund, liquid funds work — redeemable in hours, any day. For a three-year goal like a car purchase or a family trip, a target maturity or ultra-short fund matches your timeline. Gilt funds suit investors who can read interest rate cycles — they're not a place to park savings without understanding them. Since April 2023, debt funds carry no tax edge over FDs. Choose based on liquidity and duration, not a benefit that no longer exists.
Match your fund's clock to your goal's clock.
Where people go wrong
- Treating 'debt' as a synonym for 'safe'Gilt funds can lose 10–15% of NAV during a rate-hike cycle. 'Debt' describes the asset class, not your protection.
- Chasing yield without reading the underlying holdingsA 9% yield often signals lower-rated borrowers. Franklin Templeton's 2020 wind-up trapped ₹25,000 crore precisely because of credit concentration in funds marketed as income funds.
- Parking long-term savings in liquid fundsLiquid funds are cash-management tools, not wealth-builders. For goals 7 or more years away, equity does the compounding that a 7% debt fund cannot.
- Assuming the 2023 tax change doesn't apply to youAfter April 2023, debt fund gains are taxed at slab rate regardless of holding period. The FD-debt fund tax gap is closed.
Match your fund's duration to your goal: liquid for emergencies, target maturity for 3-year plans.
'Debt' doesn't mean safe. Gilt NAV can fall 10–15% when the RBI raises interest rates.
After April 2023, debt fund gains are taxed at your slab rate — identical to FD returns.
People hear 'debt fund' and picture a savings account — they find out it isn't when the NAV falls 8% in two months. 'Debt' describes who borrowed your money, not how safe your investment is.
