NCDs vs Government Bonds: A Complete Comparison for Indian Investors

The Indian fixed income market offers two primary choices: corporate Non-Convertible Debentures (NCDs) promising 8-11% yields, and government securities (G-Secs) offering the sovereign's backing at 7-7.5%. Which is right for your portfolio? This comprehensive guide examines every dimension of this crucial investment decision.

Understanding the Instruments

Non-Convertible Debentures (NCDs)

NCDs are debt instruments issued by corporations to raise capital. "Non-convertible" means they cannot be converted to equity shares—you receive interest and principal, nothing more.

Key Characteristics:

Issued by private and public companies
Higher yields (8-11%+) depending on credit quality
Credit risk exists—issuer may default
Can be secured or unsecured (backed by assets or not)
Traded on exchanges (listed NCDs) or held privately

Common Issuers:

NBFCs (Bajaj Finance, Shriram Finance, Mahindra Finance)
Infrastructure companies (L&T Finance, PFC, REC)
Housing Finance (HDFC, LIC Housing, Can Fin Homes)
Corporates (Tata Capital, Aditya Birla Finance)

Government Securities (G-Secs)

G-Secs are debt instruments issued by RBI on behalf of the Government of India to finance fiscal deficit.

Key Characteristics:

Sovereign guarantee—zero credit risk
Lower yields (6.5-7.5%) reflecting safety
Highly liquid—active secondary market
Interest rate sensitive—prices fluctuate with rate changes
Various tenures: 91-day T-bills to 40-year bonds

Types of G-Secs:

Treasury Bills (T-Bills): 91, 182, 364 days
Dated Securities: 1-40 year bonds
State Development Loans (SDLs): Issued by state governments
Floating Rate Bonds (FRBs): Variable interest linked to T-bill rates

The Risk-Return Tradeoff

Yield Comparison (January 2026)

Instrument	Typical Yield	Credit Rating	Risk Level
91-Day T-Bill	6.80%	Sovereign	Negligible
10-Year G-Sec	7.10%	Sovereign	Negligible
SDL (State Govt)	7.35%	Sovereign	Negligible
AAA Corporate NCD	7.80-8.20%	AAA	Very Low
AA+ Corporate NCD	8.30-8.70%	AA+	Low
AA Corporate NCD	8.50-9.00%	AA	Low-Moderate
A Corporate NCD	9.00-10.00%	A	Moderate
BBB Corporate NCD	10.00-12.00%+	BBB	High

The Credit Spread

The difference between corporate bond yields and equivalent G-Sec yields is called the "credit spread":

Credit Spread = Corporate Bond Yield - G-Sec Yield

Current spreads in India:

AAA over G-Sec: 70-110 bps
AA over G-Sec: 140-190 bps
A over G-Sec: 200-300 bps
BBB over G-Sec: 350-500+ bps

This spread compensates investors for:

Default risk
Lower liquidity
Higher volatility

Why Is Credit Risk the Critical Difference?

Government Bonds: Zero Default Risk

G-Secs carry the sovereign guarantee. The Government of India has never defaulted on domestic debt and is considered risk-free for rupee-denominated obligations.

Even State Development Loans (SDLs), while issued by state governments, implicitly carry central government backing—no state has ever defaulted.

NCDs: Credit Risk is Real

Corporate defaults do happen. Recent high-profile cases:

DHFL (2019)

Largest NCD default in Indian history
Rs. 84,000+ crore debt
Retail investors lost significant capital
Even "AA" rated at time of collapse

IL&FS (2018)

Infrastructure financing giant
Triggered NBFC liquidity crisis
Multiple group companies defaulted
Rating agencies criticized for missing early warnings

Reliance Capital (2022)

Anil Ambani group company
Rs. 40,000+ crore debt
Resolution through IBC
Investors faced significant haircuts

Understanding Default Probability

Historical default rates (CRISIL data):

Rating	1-Year Default Rate	3-Year Cumulative
AAA	0.00%	0.00%
AA	0.05%	0.25%
A	0.20%	1.10%
BBB	0.80%	4.50%
BB	3.50%	15.00%

Key insight: Even AA-rated bonds have historically defaulted. The spread over G-Secs isn't free money—it's compensation for real risk. Learn more about how agencies assess this risk in our credit ratings explained guide.

Liquidity Comparison

G-Secs: Highly Liquid

The government securities market is India's most liquid debt market:

Daily trading volume: Rs. 30,000-50,000 crore
Tight bid-ask spreads: 1-3 bps for benchmark securities
Instant execution: Orders filled in seconds
Transparent pricing: Real-time quotes on NDS-OM

You can buy/sell G-Secs through:

RBI Retail Direct (direct access for individuals)
Stock exchanges (NSE goBID, BSE Direct)
Mutual funds (Gilt funds, Government securities funds)
Banks and primary dealers

NCDs: Liquidity Varies Significantly

NCD liquidity depends on multiple factors:

Listed NCDs:

Traded on NSE/BSE
Liquidity varies widely by issuer
Large issuers (Bajaj Finance, HDFC) relatively liquid
Smaller issuers may have no buyers for weeks
Bid-ask spreads: 20-100+ bps

Unlisted NCDs:

No secondary market
Must hold to maturity
Early exit nearly impossible
Suitable only for buy-and-hold investors

Liquidity Reality Check: If you need to sell Rs. 10 lakh of NCDs urgently:

Bajaj Finance NCD: Likely executable, 0.3-0.5% impact
Mid-tier NBFC NCD: May take 2-5 days, 1-2% impact
Small issuer NCD: May be impossible at reasonable price

Interest Rate Risk

Both G-Secs and NCDs face interest rate risk—when rates rise, bond prices fall.

Duration: The Key Metric

Duration measures price sensitivity to interest rate changes:

Price Change ≈ -Duration × Interest Rate Change

Example: A bond with 5-year duration loses ~5% if rates rise 1%.

G-Secs: Higher Duration Risk

Long-term G-Secs (10Y, 20Y, 30Y) have high duration:

G-Sec Tenure	Approximate Duration	1% Rate Rise Impact
2 Year	1.9 years	-1.9%
5 Year	4.3 years	-4.3%
10 Year	7.5 years	-7.5%
30 Year	15.0 years	-15.0%

In 2022, when RBI hiked rates by 2.5%, long-term G-Sec holders saw 15-25% mark-to-market losses.

NCDs: Typically Lower Duration

Most NCDs have shorter maturities (2-5 years), resulting in lower interest rate risk:

NCD Tenure	Approximate Duration	1% Rate Rise Impact
2 Year	1.8 years	-1.8%
3 Year	2.7 years	-2.7%
5 Year	4.2 years	-4.2%

However: Some NCDs have call options allowing issuers to redeem early if rates fall—you may not capture the full benefit of falling rates.

How Are NCDs and Government Bonds Taxed Differently?

Tax treatment significantly impacts net returns. For comprehensive strategies, see our tax planning guide for bond investors.

Listed Bonds (NCDs and G-Secs on exchanges)

Held > 12 months (LTCG):

Tax rate: 12.5% on capital gains
No indexation benefit (from FY 2024-25)
Coupon interest taxed at slab rate

Held < 12 months (STCG):

Taxed at your income tax slab rate

Unlisted NCDs

Interest taxed as "Income from Other Sources"
Your marginal tax rate applies (up to 30% + cess)
Capital gains also at slab rate (no LTCG benefit)

Tax Comparison Example

Rs. 10 lakh investment, 3-year holding:

Aspect	Listed NCD (8.5%)	G-Sec Fund (7.2%)	Unlisted NCD (9%)
Annual Return	Rs. 85,000	Rs. 72,000	Rs. 90,000
3-Year Total	Rs. 2,55,000	Rs. 2,16,000	Rs. 2,70,000
Tax (30% slab)	~Rs. 31,875*	~Rs. 27,000*	Rs. 81,000
Net Return	Rs. 2,23,125	Rs. 1,89,000	Rs. 1,89,000

*Listed bonds: LTCG at 12.5% on gains portion

Key insight: Unlisted NCDs lose their yield advantage after taxes for high-income investors.

Building a Balanced Allocation

Conservative Portfolio (Low Risk)

Asset	Allocation	Expected Yield
G-Secs / Gilt Funds	50%	7.0%
AAA NCDs	30%	7.8%
SDLs	20%	7.3%
Weighted Average	100%	7.3%

Balanced Portfolio (Moderate Risk)

Asset	Allocation	Expected Yield
G-Secs / Gilt Funds	30%	7.0%
AAA NCDs	30%	7.8%
AA NCDs	30%	8.5%
SDLs	10%	7.3%
Weighted Average	100%	7.7%

Growth Portfolio (Higher Risk)

Asset	Allocation	Expected Yield
G-Secs	20%	7.0%
AA NCDs	40%	8.5%
A NCDs	30%	9.5%
AAA NCDs	10%	7.8%
Weighted Average	100%	8.5%

The Verdict: It's Not Either/Or

The G-Sec vs NCD decision isn't binary. Most investors benefit from holding both:

G-Secs Provide:

Safety anchor for portfolio
Liquidity for rebalancing
Crisis hedge (rally during equity selloffs)
Rate view expression

NCDs Provide:

Yield enhancement (100-200+ bps)
Regular income for cash flow needs
Diversification across issuers
Tax efficiency (if listed)

Suggested Allocation by Risk Profile

Risk Profile	G-Secs	AAA NCDs	AA/A NCDs
Conservative	70%	30%	0%
Moderate	40%	35%	25%
Aggressive	20%	30%	50%

Key Takeaways

G-Secs are truly risk-free for credit; NCDs are not—even AAA can face stress
Yield spread is compensation for real default risk, not free alpha
Liquidity matters: G-Secs trade easily; many NCDs are illiquid
Tax efficiency favors listed bonds for high-income investors
Duration risk applies to both: Long-term bonds of any type lose value when rates rise
Diversification is key: Hold both G-Secs and NCDs across ratings and issuers
Do your homework on NCDs: Rating isn't everything—analyze the issuer
Match to your needs: Income needs → NCDs; Capital preservation → G-Secs

Conclusion

Government bonds offer unmatched safety and liquidity at the cost of lower yields. Corporate NCDs offer higher returns but require careful issuer selection and tolerance for credit risk.

The optimal strategy for most investors is a blend: use G-Secs as your safe foundation and add carefully selected NCDs for yield enhancement. A bond ladder strategy can help you structure this mix across different maturities. The exact mix depends on your risk tolerance, income needs, and ability to analyze credit.

Remember: in fixed income, there are no free lunches. The extra yield on NCDs exists because there's extra risk—make sure you're being compensated adequately for the risks you take.
