India’s sovereign green bond (SGrB) market has gained significant momentum as strong investor demand has resulted in green bonds trading at a consistent “greenium” compared to similar conventional government securities.
The average greenium recorded during the first half of FY 2026-27 reached its highest level since India started issuing sovereign green bonds in FY 2022-23.
The trend reflects growing investor confidence in India’s sustainable finance framework and indicates that the market has the capacity to absorb increased issuance of green bonds in the future.
What is Greenium?
Greenium refers to the premium associated with green bonds, where investors accept a lower yield (interest rate) compared to conventional bonds because the funds are used for environmentally sustainable projects.
Since bond prices and yields move inversely, lower yields indicate that investors are willing to pay a higher price for green bonds due to their environmental benefits.
Significance of a Stable Greenium
A sustained greenium has important implications for India’s climate finance goals:
Lower Cost of Green Financing
Greenium reduces borrowing costs for the government, enabling affordable financing for projects related to:
- Renewable energy.
- Electric mobility.
- Climate adaptation.
- Clean infrastructure.
This supports India’s commitment towards achieving Net Zero emissions by 2070.

Growth of Green Finance Ecosystem

- Green bond frameworks.
- Environmental, Social and Governance (ESG) evaluation systems.
- Sustainable investment practices.
What are Sovereign Green Bonds (SGrBs)?
Sovereign Green Bonds are government-issued debt instruments introduced in the Union Budget 2022-23 to mobilise resources for projects supporting India’s transition towards a low-carbon economy.
The funds raised through these bonds are exclusively allocated to eligible green projects, ensuring transparency and accountability in their utilisation.
India’s Sovereign Green Bond Framework follows the International Capital Market Association (ICMA) Green Bond Principles (2021), enhancing credibility among global investors.
Features of Sovereign Green Bonds
Key features of SGrBs include:
- Issued through a uniform price auction mechanism.
- Eligible for repo transactions.
- Tradable in the secondary market.
- Eligible for Statutory Liquidity Ratio (SLR) requirements, allowing financial institutions to include them in mandatory investments.
These features make sovereign green bonds attractive to institutional investors.
India’s Sovereign Green Bond Framework
The Ministry of Finance introduced India’s first Sovereign Green Bond Framework in 2022.
The framework defines:
- Eligible green projects.
- Project evaluation mechanisms.
- Monitoring and reporting procedures.
The framework received validation from CICERO (Norway-based independent research institute), which assigned it a “Medium Green” rating with “Good Governance”.
This confirmed its alignment with global green bond standards.
Management and Monitoring of Sovereign Green Bonds
The proceeds from SGrBs are deposited into the Consolidated Fund of India and managed through the Public Debt Management Cell (PDMC) under the Ministry of Finance.
Important mechanisms include:
- Green Register: Maintains details of funded green projects.
- Green Finance Working Committee (GFWC): Oversees project selection and evaluation under the chairmanship of the Chief Economic Adviser.
- Comptroller and Auditor General (CAG): Ensures audit and accountability of fund utilisation.
Current Status of India’s Green Bond Market
India’s sovereign green bond market has expanded rapidly.
- Outstanding sovereign green bonds are valued at around ₹877 billion.
- Long-term 30-year green bonds have emerged as the dominant segment.
- Outstanding issuance of long-duration green bonds has crossed ₹500 billion.
Although some initial issuances faced challenges due to limited investor demand at acceptable yields, market confidence has improved with rising institutional participation.
Factors Driving Demand for Sovereign Green Bonds
Investment Requirements of Insurance Companies
Insurance companies require long-term investment instruments to match their long-term liabilities.
Green bonds, especially long-maturity bonds, provide suitable investment opportunities.
Infrastructure Investment Benefits
Green bonds are classified as infrastructure investments, providing financial institutions with greater flexibility in allocating funds.
This increases their attractiveness among institutional investors.
Asset-Liability Management (ALM) Needs
Pension funds and insurance companies follow strict Asset-Liability Management practices.
Long-term sovereign green bonds align well with their requirement for stable and predictable returns over extended periods.
Conclusion
India’s sovereign green bond market represents an important step towards building a sustainable financial ecosystem.
The emergence of greenium demonstrates increasing investor confidence in India’s climate finance strategy and the credibility of its green investment framework.
By expanding green bond issuance, improving transparency and attracting institutional investors, India can mobilise resources for renewable energy, sustainable infrastructure and climate resilience while progressing towards its Net Zero 2070 commitment.
