Zero-Coupon Bond

A zero-coupon bond turns the usual bond mechanic on its head. Instead of paying interest along the way, it is sold cheap and redeemed at par. You buy below face value, hold to maturity, and collect the full face value; the gap between the two is your return.

How it works

Because there are no coupons to reinvest, your return is locked in at purchase, assuming you hold to maturity and the issuer does not default. The trade-off is no interim cash flow, so these suit investors targeting a fixed future sum, such as a child's college fund or a known liability.

In India

The most familiar zero-coupon instruments are Treasury Bills (T-Bills) issued by the RBI with maturities up to 364 days; they are sold at a discount and redeemed at par. Longer-dated zero-coupon and deep-discount bonds have been issued by entities like NABARD and various PSUs. Retail investors can access T-Bills through RBI Retail Direct or via the NSE and BSE.

Taxation

The return on a zero-coupon bond is generally treated as capital gains, taxed at maturity rather than accrued annually. Whether it is short-term or long-term depends on the holding period and the bond's classification. This is an important distinction from regular bonds, whose coupon is taxed as income each year at your slab rate. Always verify the exact treatment for the specific bond, as rules differ between notified and unlisted instruments.

Why it matters

Zero-coupon bonds remove reinvestment risk: you know exactly what you will receive and when. But they are more sensitive to interest-rate changes than coupon-paying bonds of the same maturity, so their market price swings more if you sell early. They also tie up money with no interim income. For a disciplined investor matching a future goal to a fixed payout, they are a clean, predictable tool, best held to maturity.
