AAA Corporate Bonds Yield 7.48%. G-Secs Yield 6.69%. The Pre-Tax Spread Is 79 Basis Points. After Tax at 30% Bracket, It Shrinks to 56 bps. Factor in Liquidity Risk, Exit Costs, and the DHFL Precedent — and You Start Wondering Why You Bothered.
Every comparison of corporate bonds versus government bonds in India shows the same table: corporate bonds yield more, government bonds are safer, pick based on your risk appetite.
That framing is incomplete. It ignores three things that change the math entirely: taxation, liquidity, and what actually happens when you try to sell.
The Yield Comparison Everyone Shows You
| Instrument | Yield (March 2026) | Rating |
|---|---|---|
| 10Y G-Sec | 6.69% | Sovereign |
| AAA Corporate Bond (10Y) | 7.48% | AAA |
| AA Corporate Bond | 8.5-10% | AA |
| Below-AA Corporate Bond | 10-12%+ | A and below |
| RBI Floating Rate Savings Bond | ~8.05% | Sovereign |
The spread looks attractive. AAA bonds yield 79 bps more than G-Secs. AA bonds yield 180-330 bps more. Below-AA paper crosses 10%.
This is the table that gets you excited. The next table is the one that matters.
The After-Tax Yield Nobody Shows You
Bond interest is taxed at your income tax slab rate. Not at a special rate. Not at 12.5%. At your full slab rate.
| Instrument | Pre-Tax Yield | After-Tax (20% slab) | After-Tax (30% slab) |
|---|---|---|---|
| 10Y G-Sec | 6.69% | 5.35% | 4.68% |
| AAA Corporate Bond (10Y) | 7.48% | 5.98% | 5.24% |
| AA Corporate Bond (9%) | 9.00% | 7.20% | 6.30% |
| RBI Floating Rate Bond | 8.05% | 6.44% | 5.64% |
| PPF (tax-free) | 7.10% | 7.10% | 7.10% |
At the 30% tax bracket, your AAA corporate bond yields 5.24% after tax. PPF yields 7.10% tax-free. The “safe” government-backed option beats the “higher yield” corporate bond by 186 basis points.
The pre-tax spread of 79 bps between AAA corporates and G-Secs shrinks to just 56 bps after tax at 30%. That 56 basis points must compensate for:
- Credit risk (yes, even AAA bonds can default)
- Liquidity risk (good luck selling before maturity)
- Exit costs (bid-ask spreads that eat your yield)
For most salaried investors in the 30% bracket, the math does not justify buying individual AAA corporate bonds over G-Secs or PPF.
The Liquidity Problem Nobody Talks About
India’s corporate bond secondary market has an annual turnover ratio of just 0.3x. That means for every Rs 100 of bonds outstanding, only Rs 30 trades in an entire year.
Compare this to equity markets where turnover ratios exceed 1x, or even US bond markets where institutional secondary trading is routine.
What This Means for You
- Buying: Easy. Platforms like GoldenPi, Jiraaf, and Wint Wealth let you buy from Rs 10,000 (reduced from Rs 1 lakh in July 2024)
- Holding to maturity: Fine. You collect coupons and get principal back
- Selling before maturity: This is where it breaks
When you try to sell a corporate bond on the secondary market, you face:
| Factor | Impact on Returns |
|---|---|
| Bid-ask spread (retail) | 25-100+ bps loss |
| Low buyer count | May not find a buyer at all |
| Price discovery | Opaque, no real-time market depth |
| Platform exit fee | Varies by OBPP |
A 50 bps bid-ask spread on a bond you held for 1 year wipes out 63% of the yield advantage AAA corporate bonds have over G-Secs. Hold for 6 months and try to sell — you likely lose money net of the spread.
If you cannot hold a corporate bond to maturity, you should not buy one directly.
Government Bonds: The Liquidity Advantage
G-Secs are far more liquid than corporate bonds. Institutional trading is active, and the RBI Retail Direct platform provides direct access:
| Feature | RBI Retail Direct | OBPP Platforms |
|---|---|---|
| Account charges | Free | Free (most) |
| Brokerage | Zero | 0-0.5% |
| Minimum investment | Rs 1,000 | Rs 10,000 |
| Available instruments | G-Secs, T-Bills, SDLs, SGBs | Corporate bonds, some G-Secs |
| Secondary market exit | Better (institutional market) | Very poor |
| Credit risk | Zero (sovereign guarantee) | Depends on rating |
| Regulatory body | RBI | SEBI |
The UX of RBI Retail Direct is poor — clunky interface, limited auction information, no advisory layer. But it is the cheapest and safest way for retail investors to access government bonds in India.
The DHFL Warning: AAA Does Not Mean Risk-Free
CRISIL’s annual default study shows near-zero default rates for AAA-rated entities. The aggregate number looks reassuring.
Then there is DHFL.
Dewan Housing Finance Corporation was rated AAA by multiple rating agencies. In 2019, it defaulted. Retail investors who held DHFL bonds and fixed deposits lost crores. The company went into bankruptcy proceedings. Rating agencies faced no meaningful consequences.
The aggregate default rate is irrelevant if you are the one holding the bond that defaults.
Default rates by rating (India, FY2025)
| Rating | 1-Year Default Rate | 3-Year Cumulative Default Rate |
|---|---|---|
| AAA | ~0% | ~0% |
| AA | ~0.1% | ~0.3% |
| A | ~0.3% | ~1.0% |
| BBB | ~0.44% | ~1.92% |
| Below BBB | Significantly higher | Significantly higher |
These numbers look small. But SEBI now defines default as “a delay of 1 day, even of 1 Rupee of principal or interest from the scheduled repayment date.” The bar for default is low. The consequence for the investor is high.
If you buy individual corporate bonds, never put more than 5% of your bond allocation in any single issuer. Diversification is not optional in credit markets.
The Callable Bond Trap
Many corporate bonds on OBPP platforms advertise yields of 10-12%. The headline number looks attractive.
Check the fine print for embedded options:
- Callable bonds: The issuer can redeem the bond early (typically when rates fall). You get your principal back but lose the high-yield position exactly when reinvestment rates are lower
- Putable bonds: You can sell the bond back to the issuer before maturity (rare, and usually at a discount)
- Convertible bonds: The bond can convert to equity, changing your risk profile entirely
The most common trap: A bond advertises 11% yield to maturity over 7 years. But it has a call option exercisable in 2 years. When rates drop, the issuer calls the bond. Your actual holding period is 2 years, not 7, and you must reinvest at lower rates.
Before buying any corporate bond, search the ISIN on the exchange website and check the offer document for embedded options. If a bond yields significantly more than comparable paper with no apparent credit difference, there is usually a call provision explaining the gap.
Tax Treatment: The 12-Month LTCG Advantage Most Investors Miss
Post-July 2024, all bond gains — listed and unlisted, government and corporate — follow these rules:
Interest Income
- Taxed at your income tax slab rate (up to 30% + cess)
- TDS of 10% deducted when annual interest exceeds Rs 10,000
Capital Gains
| Scenario | Listed Bonds | Unlisted Bonds |
|---|---|---|
| Short-term holding | 12 months or less | 24 months or less |
| STCG tax rate | Slab rate (up to 30%) | Slab rate (up to 30%) |
| Long-term holding | More than 12 months | More than 24 months |
| LTCG tax rate | 12.5% flat | 12.5% flat |
| Indexation | None | None |
The planning angle most investors miss: Buy a listed bond at a discount (below face value). Hold for 12 months + 1 day. Sell at or near face value. The capital gain is taxed at 12.5% — far cheaper than the 30% slab rate on interest income.
This does not work for all bonds (many trade at par or premium), but for discounted bonds in the secondary market, the capital gains route is more tax-efficient than collecting interest.
Important: The indexation benefit that made debt mutual funds attractive for 3+ year holdings is gone permanently under the new rules. Capital gains on both bonds and debt funds are now taxed at 12.5% without indexation.
Mutual Funds vs Direct Bonds: The Honest Comparison
5-Year Returns (as of 2026)
| Category | Fund | 5Y Return |
|---|---|---|
| Gilt Funds | SBI Magnum Gilt | 6.12% |
| HDFC Gilt | 5.56% | |
| Corporate Bond Funds | ICICI Pru Corporate Bond | 6.67% |
| Axis Corporate Bond | 6.66% | |
| Franklin India Corporate Debt | 6.63% |
Key Differences
| Factor | Direct Bonds | Bond Mutual Funds |
|---|---|---|
| Diversification | Single issuer risk | 30-50+ issuers |
| Credit analysis | You do it yourself | Professional credit team |
| Liquidity | Very poor (corporate) | Next-day redemption |
| Cost | Zero (RBI Retail Direct) / 0-0.5% (OBPP) | 0.1-0.5% expense ratio |
| Tax on interest | Slab rate | N/A (fund level) |
| Tax on gains | 12.5% LTCG (12 mo listed) | 12.5% LTCG (24 mo) |
| Minimum amount | Rs 1,000-10,000 | Rs 100-500 (SIP) |
The verdict: For most retail investors, corporate bond mutual funds are better than buying individual corporate bonds. You get professional credit assessment, diversification, and daily liquidity. The expense ratio is the price of not being the next DHFL victim.
Direct G-Secs via RBI Retail Direct make sense for hold-to-maturity investors who want zero cost and zero credit risk.
The Credit Spread Is Compressing — And That Is Bad for Retail
AAA corporate bond spreads over G-Secs have compressed from 120-150 bps three years ago to 80-100 bps today. Why?
- FPI inflows: Foreign portfolio investors pumped Rs 1.21 trillion into corporate bonds in FY25, up 11.4% YoY
- Institutional demand: Insurance and pension funds are mandated to hold high-grade debt
- Limited supply: 97% of issuances are AA-rated or above, concentrating demand in a small pool
This compression means you are being paid less for taking credit risk than you were 3-4 years ago. The risk has not decreased — the compensation has.
The Barbell Strategy: When It Makes Sense
Sophisticated bond investors skip AAA corporate bonds entirely. Instead, they use a barbell:
Left side: G-Secs (zero credit risk, pure interest rate exposure, good liquidity)
Right side: Sub-AA corporate bonds or credit risk funds (high yield, genuine credit risk, illiquid)
Why skip the middle? AAA corporate bonds offer the worst of both worlds — you accept credit risk without meaningful extra yield. The 56 bps after-tax spread over G-Secs is not worth the downgrade in liquidity and safety.
The barbell only works if you can genuinely assess credit risk on the right side. If you cannot read a balance sheet, calculate debt-service coverage ratios, and evaluate industry risk, stick with corporate bond mutual funds where a professional team does this work.

SEBI’s new Liquidity Window facility (2025) now requires issuers to offer periodic buyback windows for listed bonds. This is a structural improvement for retail exit options, but adoption is still early and most issuers treat it as a compliance checkbox rather than a genuine liquidity solution.
India’s Corporate Bond Market: The Structural Reality
NITI Aayog’s December 2025 report lays out the numbers:
- Corporate bond market: 18% of GDP (India) vs 120%+ (US)
- Secondary market turnover: 0.3x annually
- Retail participation: Negligible as share of total market
- Issuance concentration: 85-90% of non-financial issuers rated AA or above
- Market growth needed: 5-7x to reach global benchmarks
The market is growing — retail bond transactions surged 327% YoY after SEBI reduced OBPP minimums. But the structural illiquidity and institutional dominance will take a decade to meaningfully change.
The Decision Framework
Choose Government Bonds (G-Secs) If:
- You want zero credit risk with sovereign guarantee
- You can hold to maturity (or accept duration risk in gilt funds)
- You want the cheapest access (free via RBI Retail Direct)
- You are in the 30% tax bracket and PPF is already maxed
- You want exposure to interest rate moves (gilt funds for rate cut bets)
Choose Corporate Bonds If:
- You need yield above 8% and understand credit risk
- You can commit to holding until maturity (no early exit)
- You are buying through a mutual fund for diversification
- You have verified there are no embedded call options killing your yield
- No single issuer exceeds 5% of your bond allocation
Choose Neither Directly If:
- You are in the 30% bracket — PPF at 7.1% tax-free beats both after tax
- You need liquidity — use a liquid fund or corporate bond fund instead
- You cannot evaluate credit risk — let a fund manager do it
- Your bond allocation is under Rs 5 lakh — diversification is impossible at that size with individual bonds
The Bottom Line
The 79 bps pre-tax spread between AAA corporate bonds and G-Secs is a marketing number. After tax, after liquidity costs, after exit friction, the real advantage is 0-30 bps for a retail investor in the 30% bracket.
Government bonds are free to buy, sovereign-guaranteed, and more liquid. Corporate bonds pay a small premium for material additional risk.
For most retail investors in India, the right answer is: max out PPF first, buy G-Secs via RBI Retail Direct for additional fixed income, and use corporate bond mutual funds — not individual bonds — for any yield pickup.
The corporate bond market will mature. Liquidity will improve. SEBI’s reforms are real. But in 2026, the infrastructure is not ready for retail investors to buy individual corporate bonds and expect a smooth experience.
Buy the yield. Hold to maturity. Or buy the fund.
