06 May 2025 Ā· Sachin Gadekar
A deep dive into how zero-coupon bonds work, their advantages, risks, and strategies to maximize returns while minimizing surprises.
Introduction
Zero-coupon bonds are often misunderstood and underutilizedāyet they offer a powerful way to lock in fixed returns over time. At TapBonds.com, our mission is to simplify and democratize access to the bond market. This article explains what zero-coupon bonds are, why they matter, and how smart investors can integrate them into a modern portfolio strategy.
š§¾ What Are Zero-Coupon Bonds?
Zero-coupon bonds are fixed-income securities that donāt pay periodic interest (or ācouponā) during their term. Instead, they are issued at a deep discount and mature at face value. The difference between the purchase price and maturity value is the investorās return.
Example:
A bond with a face value of ā¹1,00,000 might be sold for ā¹70,000. After 10 years, the investor receives ā¹1,00,000, earning ā¹30,000 in interest over the period.
ā Why Investors Consider Zero-Coupon Bonds
āļø Predictable returns: You know exactly how much you'll receive at maturity.
āļø No reinvestment risk: Unlike regular coupon-paying bonds, you donāt need to worry about reinvesting interest at varying rates.
āļø Great for long-term goals: Ideal for funding future obligationsālike childrenās education or retirement.
š Key Strategies for Investing in Zero-Coupon Bonds
1. Match Maturity with Goals (Laddering Strategy)
Zero-coupon bonds are most effective when timed with your financial goals. For example, if you need ā¹10 lakh for your childās education in 2035, you could purchase a zero-coupon bond that matures that year and provides that amount.
Benefits:
Perfect alignment of cash flow and need
Avoids timing the market
Minimizes reinvestment risk
2. Use in Tax-Efficient Accounts
In India, the accrued interest on zero-coupon bonds is taxable annually (even though you receive it only at maturity). This creates a āphantom incomeā problem.
Pro tip: Invest through tax-efficient vehicles like:
Debt Mutual Funds (before the new taxation rule changes in 2023)
Insurance Wrappers / ULIPs
Retirement Accounts where tax is deferred or exempt
3. Barbell Strategy for Risk Management
Combine short-term liquid investments with long-term zero-coupon bonds to create a barbell structure in your fixed-income portfolio.
Short-term end: For liquidity and flexibility
Long-term zero-coupon bonds: For locked-in returns and growth
This helps manage interest rate risk while capturing long-term appreciation.
4. Buy When Interest Rates Are High
Zero-coupon bonds are highly sensitive to interest rate changes because they donāt offer interim payments.
Buy when rates are high, because:
You lock in higher yields
Bond prices are lower (you get a deeper discount)
You benefit from greater compounding over time
5. Diversify Across Credit Ratings
Many zero-coupon bonds are issued by public sector undertakings (PSUs) or highly rated corporations, but others come from lower-rated issuers.
Use platforms like TapBonds.com to evaluate credit quality and diversify your holdings.
Tip:
Mix AAA-rated with select A or BBB-rated bonds
Look at debt servicing history and business model of the issuer
6. Hold Till Maturity (HTM)
Zero-coupon bonds can be volatile if sold before maturity because theyāre sensitive to market interest rates.
Holding to maturity ensures:
Full redemption at face value
No capital loss due to interim market fluctuations
No stress over tracking daily NAV or price changes
