If you want predictable, non-equity returns in India, one usually has three real choices: a bank fixed deposit, a debt mutual fund, or a bond bought directly. Most investors default to whichever one they learned about first, usually the fixed deposit (FD), without ever comparing all three of them side by side. Here's a brief comparison of these instruments.
What each instrument actually is
A fixed deposit is a private contract between you and a bank: you hand over your principal, the bank pays a fixed rate of interest, and returns your principal at maturity. A debt mutual fund pools money from many investors and uses it to buy a portfolio of bonds on their behalf, charging an ongoing fee (the expense ratio) for management of the fund. A bond is a direct loan from you to a company or government (the issuer), which pays you regular interest and returns your principal at maturity but, unlike an FD, it's a tradable security you can buy or sell on the National Stock Exchange or Bombay Stock Exchange.
Returns
- Fixed deposits: typically 5–8%, depending on the bank and tenure.
- Debt mutual funds: returns typically around 6–8%, except for an annual expense ratio which slightly lowers returns each year.
- Bonds: generate returns of about 8% to 14%, as investors are compensated for taking on company-specific credit risk. Government bonds, by contrast, tend to offer lower returns of around 6% to 7% but come with the reassurance of sovereign backing.
Liquidity
This is where the three options differ most. Breaking a Fixed Deposit before maturity usually means going back to the bank and paying a penalty. A debt mutual fund, by contrast, can typically be redeemed on any business day, with the proceeds based on that day's Net Asset Value (NAV). Because the NAV reflects the market value of the fund's underlying bond portfolio, the amount you receive is not perfectly predictable. A bond held directly in a dematerialised (demat) account can generally be sold on exchange at any time to another investor at the prevailing market price, with no prepayment penalty. However, the price you receive will depend on market conditions at the time of sale.
Transparency and control
With a bond, you know exactly which issuer you've lent to, its credit rating, coupon rate and maturity date. With a debt fund, the manager rebalances the underlying portfolio over time, so the credit quality and average maturity you're exposed to can shift without you doing anything. An FD is transparent in a narrower sense: you know your bank and your rate, but you have no visibility into or control over how that bank deploys your deposit.
Cost
FDs and bonds carry no ongoing management fee or expense ratio. What you're quoted is generally close to what you earn, before tax. Debt mutual funds charge an expense ratio every year, regardless of performance, which quietly compounds against you over a multi-year holding period.
Taxation
FD interest is taxed entirely at your income slab rate. Bonds can generate both interest (taxed at your income slab rate) and capital gains (taxed at slab rate if held for less than 12 months, or a flat 12.5% if held for more than 12 months), a structural tax advantage FDs don't have. Debt mutual fund gains are taxed at your income slab rate. However, you invest through fund units rather than owning the underlying debt directly, with no additional tax benefit from using the fund structure. There is also no distinction between holding periods and no indexation benefit.
Where each one genuinely wins
- FDs win on simplicity for very small, short-term parking of cash, where the convenience of a five-minute banking-app transaction matters more than yield.
- Debt funds win for investors who want systematic investment plan (SIP)-style monthly investing discipline or true same-day-ish liquidity in very small amounts, and are comfortable paying for that convenience.
- Direct bonds win on yield, tax efficiency and control for anyone willing to spend a few minutes comparing credit rating, tenure and yield, which, on a platform built for it, is genuinely all it takes.
The bottom line
None of the three is wrong. Each solves a different problem. The key is understanding what you're paying for. FDs offer simplicity, debt funds offer convenience and diversification, and direct bonds offer control, transparency and, in many cases, higher post-tax returns.
But if your reason for choosing an FD or a debt fund was simply “I didn't know how else to access bonds,” that reason has mostly disappeared. The friction that used to justify the fund wrapper, or the FD's convenience premium, has largely disappeared.
