Gilt Fund

Gilt Fund

A gilt fund is a type of debt mutual fund that invests at least 80% of its assets in government securities issued by the central or state governments. These securities are called gilt securities, a term inherited from the British practice of issuing bonds with gold-edged certificates. In India, gilt funds invest specifically in instruments issued by the Reserve Bank of India on behalf of the central and state governments, including government bonds, treasury bills, and state development loans.

The Securities and Exchange Board of India mandates the 80% allocation threshold for schemes classified as gilt funds. The Association of Mutual Funds in India categorizes gilt funds as a sub-segment of open-ended debt funds.

How Gilt Funds Work in India

When the central or state government needs to raise money, it approaches the Reserve Bank of India, which serves as the government's banker. The Reserve Bank of India borrows from banks, insurance companies, and other institutional investors, then issues government securities with fixed maturities and predetermined coupon rates. Gilt funds subscribe to these securities on behalf of their investors.

When a security matures, the fund receives the principal back along with all coupon payments made during the holding period. The fund's net asset value fluctuates daily based on the market prices of the securities it holds.

Two Types of Gilt Funds

Gilt funds in India fall into two categories based on how they manage maturity exposure.

  • Standard gilt funds: Invest in government securities across a range of maturities, from short-term treasury bills to long-dated bonds. The fund manager adjusts duration based on interest rate expectations.
  • Gilt funds with 10-year constant maturity: Required to maintain at least 80% of assets in securities with a 10-year maturity profile. These funds carry higher interest rate sensitivity but offer more consistent duration exposure.

Credit Risk Is Nearly Zero, But Interest Rate Risk Is Real

Because the Indian government backs every security in a gilt fund's portfolio, the probability of default is effectively zero. No Indian government has ever failed to honor its sovereign debt obligations.

Interest rate risk is a different story entirely. Bond prices move inversely with interest rates. When the Reserve Bank of India raises its repo rate, the prices of existing government securities fall because new bonds offer higher yields, making older ones less attractive. A 1% rise in interest rates on a 10-year government bond can reduce the bond's market price by roughly 7% to 8%, depending on its coupon structure.

Returns Compared to Bank Fixed Deposits

As of April 2024, gilt funds across the category delivered annualized returns ranging from 5.78% to 8.82%. Major Indian banks were offering fixed deposit rates between 6.6% and 7.1% for comparable tenors during the same period. Gilt funds can outperform bank deposits when interest rates are declining because falling rates push bond prices up.

Unlike bank fixed deposits, gilt fund returns are market-linked and not guaranteed. The Deposit Insurance and Credit Guarantee Corporation insures bank deposits up to Rs 5 lakh per account. No such insurance applies to mutual fund investments.

Tax Treatment for Gilt Fund Investors

For investments made after April 1, 2023, all capital gains from gilt funds are taxed at the investor's applicable income tax slab rate, regardless of how long you held the investment. This change eliminated the indexation benefit that previously applied to long-term debt fund gains and made gilt funds less tax-efficient for investors in higher tax brackets compared to earlier rules.

Who Should Invest in Gilt Funds

Gilt funds work best for specific investor profiles. Conservative investors who need zero credit risk but are willing to tolerate interest rate volatility are the clearest fit. Risk-averse investors with a 3 to 5-year horizon benefit from the stability of government-backed paper while generating returns higher than most savings products.

Gilt funds also work well as a portfolio stabilizer for investors with a heavy equity allocation. During stock market downturns, government bonds often perform well as investors shift to safety, which partially offsets equity losses in a diversified portfolio.

How to Enter and Exit at the Right Time

Gilt funds deliver the best returns when you enter during a high-interest-rate environment and hold through the rate-cutting cycle. Entering just before rate cuts means you capture both the coupon income and the price appreciation that occurs as rates fall.

Entering when rates are low and rising is the worst scenario. If rates rise after you invest, the market value of the fund's bond portfolio falls, producing losses on paper even while the coupon payments continue. Knowing the direction of interest rates before investing is the single most important factor in gilt fund timing.
