Corporate bond interest rates in India 2026: Current rates by rating, sector, and how they compare to FDs

Introduction

Corporate bond interest rates in India in 2026 span a wider range than most investors realise — from 7.0% on top-rated PSU paper to 13%+ on the lowest investment-grade bonds. Understanding why this range exists, what drives the differences, and where the current rate environment sits relative to FDs is foundational to investing in corporate bonds intelligently.

The RBI has cut the repo rate by 50 basis points in 2026 to 5.25%. The 10-year G-Sec yield is now approximately 6.9%. For investors evaluating corporate bonds against FDs, the question is not just "which pays more?" but "what rate difference am I getting, and what risk am I taking for it?"

This article provides a complete breakdown of corporate bond interest rates by rating, sector, and tenure in 2026, benchmarked against FDs. All content is educational and does not constitute investment advice.

How Corporate Bond Interest Rates Are Set in India

Corporate bond coupon rates are determined at issuance by four factors:

Factor 1: RBI repo rate (base floor): Sets the floor for all borrowing costs. Currently 5.25%.

Factor 2: G-Sec yield (risk-free benchmark): The 10-year Government Security yield (~6.9%) is the primary pricing benchmark. Every corporate bond issuer pays a premium above this — the credit spread.

Factor 3: Credit spread (issuer-specific premium): The additional yield above G-Sec reflecting default risk. Rating agencies (CRISIL, ICRA, CARE, India Ratings) set the rating; the market sets the spread.

Factor 4: Tenure premium: Longer-tenure bonds require higher coupons. Investors demand compensation for longer lock-in.

Spreads and yields are indicative as of Q2 2026. Subject to change. Not a recommendation.

The spread is the market's real-time assessment of credit risk. When spreads widen typically during economic stress, credit events, or liquidity tightening corporate bond yields rise even if the G-Sec yield is unchanged. When spreads tighten, yields fall. An investor monitoring corporate bond rates should watch both the absolute yield and the spread above G-Sec.

Yields indicative as of Q2 2026. Not a recommendation.

The principle is simple: every notch down the rating scale adds approximately 100–200 basis points to the yield. This extra yield is compensation for additional default risk not additional value at the same risk. A 12% BBB corporate bond is not twice as good as a 6% government bond; it is a different risk profile with meaningfully higher credit uncertainty.

Corporate Bond Interest Rates by Sector — 2026

Interest rates also vary by sector, even within the same rating category. Sector-specific risk factors, regulatory environment, and institutional investor appetite all influence where within a rating band a specific issuer prices:

What Tenure Does to Corporate Bond Rates

Tenure is the second most important driver of corporate bond yield after credit rating. The yield curve — the relationship between yield and maturity for the same issuer is almost always upward-sloping:

Yields purely illustrative. Actual yields vary by specific issuer, market conditions, and issuance structure. Not a recommendation.

The tenure premium is the compensation investors demand for longer lock-in — more time for rates to move, more time for the issuer's credit quality to change. In the current falling rate environment, longer-tenure bonds also offer an opportunity to lock in today's rates before further cuts potentially push new issuances lower.

How the RBI Rate Cycle Has Affected Corporate Bond Rates in 2026

The RBI cut the repo rate by 25 bps in February 2026 and a further 25 bps in April 2026, taking it to 5.25%. The impact on corporate bond rates has been direct:

G-Sec yields have fallen: The 10-year G-Sec yield dropped from approximately 7.2% in January 2026 to approximately 6.9% by Q2 2026 a decline of about 30 basis points. The full 50 bps of repo rate cuts has not been fully transmitted to the long end of the yield curve.

Corporate bond yields have followed: AAA NBFC bond yields have fallen broadly in line with G-Sec yields. A Bajaj Finance NCD that offered 8.5% in early 2025 might be issued at 8.0% today for the same tenor. New issuances in 2026 carry lower coupons than equivalent issuances from FY2024–25.

Implication for investors: Bonds locked in at 2024–25 coupon rates are now priced above face value in the secondary market they offer higher income than equivalent new issuances. For new investors evaluating primary market NCDs in 2026, yields are lower than they were 12–18 months ago.

For a detailed explanation, refer to RBI Repo Rate Cut: Impact on Bond Yields and Prices.

Indicative as of Q2 2026. Not a recommendation.

The yield premium over bank FDs is real — but it comes with a trade-off at every level. AAA PSU bonds offer 25–75 bps over large bank FDs with implicit GoI backing. As you move down the rating scale, the premium grows but so does credit risk. There is no free yield.

Post-Tax Corporate Bond Yields vs FD Yields

Both corporate bond coupon income and FD interest are taxed at the investor's slab rate so the pre-tax yield advantage translates proportionally to post-tax. However, there is a structural difference: no TDS on listed bonds in Demat form for resident Indians. Bank FDs deduct 10% TDS when annual interest exceeds Rs. 50,000 per bank.

Why Corporate Bond Rates Differ Even Within the Same Rating

Two bonds can carry the same AA rating and still offer meaningfully different yields. Several factors drive intra-rating differentiation:

Issuer size and recognition: A large, widely covered NBFC like Mahindra Finance trades at tighter spreads than a smaller, lesser-known AA-rated issuer institutional investors have more comfort with the name.

Sector outlook: A AA housing finance company operating in a market with rising NPAs may trade wider than a AA diversified NBFC with stable credit quality even at the same letter grade.

Recent rating action: A bond that was recently downgraded to AA from AA+ trades wider than one that has held AA for five stable years the direction of travel matters.

Liquidity of the specific series: A large, well-distributed NCD series trades at tighter yields than a small, illiquid series from the same issuer investors price in the liquidity premium.

Tenure: As discussed longer tenor consistently commands a higher yield even within the same issuer and rating.

This is why comparing corporate bond rates requires looking beyond the credit rating letter to the full context of the issuer's financial health, sector conditions, and specific bond series characteristics. For a complete evaluation framework, refer to How to Read a Bond Offer Document in India.

How to Find and Compare Corporate Bond Interest Rates in India

SEBI-registered OBPP platforms: OBPP Platform like BondScanner display listed bonds with YTM, credit rating, coupon, and maturity in one place allowing direct comparison across issuers and rating categories. Visit bondscanner.com/bonds.

NSE and BSE: The NSEgoBID and BSEDirect portals list open NCD public issues with coupon rates and series details. The NSE and BSE debt segment pages show YTM for listed secondary market bonds by ISIN.

Rating agency websites: CRISIL, ICRA, and CARE publish detailed rating rationales that include the issuer's expected borrowing cost useful for understanding where a specific issuer is pricing relative to peers.

Key metric to use: Always compare YTM not coupon rate when evaluating secondary market bonds. For primary market bonds at face value, YTM equals the coupon rate.

Key Risks That Affect Corporate Bond Returns

Interest rate risk: If market rates rise after investment, the secondary market price of your corporate bond falls. Hold-to-maturity investors avoid this but face reinvestment risk on coupon payments.

Credit risk: Higher-yielding bonds carry higher default probability. The yield premium is the market's compensation for this risk — not extra value at the same risk level.

Liquidity risk: Not all listed corporate bonds trade actively. Thin secondary market volumes create exit risk for investors who cannot hold to maturity.

Reinvestment risk: In a falling rate environment, coupon payments received must be reinvested at lower available rates reducing effective total return versus the stated coupon.

Spread widening risk: Even without a credit event, if the market's perception of credit risk increases (spread widens), the secondary market price of an existing bond falls.

FAQs

What are the current corporate bond interest rates in India in 2026?

Corporate bond rates range from 7.0% to 13%+ depending on credit rating. AAA: 7.0%–8.3%. AA: 8.0%–9.5%. A: 9.5%–11.5%. BBB: 11.5%–13%+. Rates change with RBI policy movements and market conditions.

How are corporate bond interest rates set in India?

Four factors: the RBI repo rate (base floor), the 10-year G-Sec yield (risk-free benchmark currently ~6.9%), the credit spread above G-Sec (determined by the issuer's rating), and the bond's tenure. Higher-rated issuers pay narrower spreads; lower-rated issuers pay wider spreads.

Are corporate bonds better than FDs in India?

Corporate bonds offer higher pre-tax yields than large bank FDs — 7.4%–8.3% (AAA) vs 6.25%–7.00% (large bank FD). After tax, the advantage narrows. FDs are DICGC-insured up to Rs. 5 lakh; corporate bonds carry no insurance. The better choice depends on investment amount, tax bracket, and liquidity needs.

What is the credit spread on corporate bonds in India?

The credit spread is the additional yield above the G-Sec benchmark. AAA PSU bonds: 10–60 bps above G-Sec. AAA private NBFC: 50–140 bps. AA: 100–260 bps. A: 260–460 bps. BBB: 460–640+ bps.

Why do two AA-rated corporate bonds have different interest rates?

Same-rating bonds differ due to issuer size and recognition, sector outlook, recent rating trajectory, liquidity of the specific series, and tenure. A recently downgraded AA issuer or one in a stressed sector will trade at a wider spread than a stable, long-standing AA issuer.

Do corporate bond interest rates change after issuance?

The coupon rate is fixed at issuance and does not change. However, the YTM — the effective return at current market price — changes daily as the bond's secondary market price moves with interest rates and credit conditions.

How do I compare corporate bond interest rates in India?

Use YTM not coupon rate for secondary market comparison. OBPP platform such as BondScanner aggregates listed bonds with YTM at bondscanner.com/bonds.
