Sovereign Green Bonds in India: Rising Greenium and Growth of Green Finance
Why in News?
India’s sovereign green bond market is showing stronger investor interest. Recent issuances have demonstrated a greenium, where investors accept lower yields on green bonds than comparable conventional government securities.
In April 2026, India’s 30-year sovereign green bond recorded a 6-basis-point greenium, the strongest since January 2023. The issue was subscribed around 2.5 times.
What is Greenium?
Greenium refers to the lower yield investors accept on a green bond compared with a similar conventional bond. Investors therefore pay a relatively higher price for environmentally sustainable investments.
Since bond prices and yields move inversely, a lower yield can reduce the government’s borrowing cost.
A stable greenium can indicate stronger investor preference for sustainable assets. It can also support India’s growing green finance ecosystem.
What are Sovereign Green Bonds?
Sovereign Green Bonds (SGrBs) are government debt instruments used to finance eligible projects supporting India’s transition towards a low-carbon economy.
India announced sovereign green bonds in the Union Budget 2022–23. The government subsequently issued its first sovereign green bonds in January 2023.
India’s Sovereign Green Bond Framework defines eligible projects and strengthens transparency in the use of proceeds. The Department of Economic Affairs continues to publish allocation and impact reports under the framework.
Why are Green Bonds Important?
Green bonds can mobilise capital for projects such as renewable energy, clean transportation, energy efficiency, climate adaptation, sustainable water management and biodiversity conservation.
They can therefore support India’s climate commitments, including the goal of achieving net-zero emissions by 2070.
The government has also planned substantial green-project financing for FY2026–27. Projects worth nearly ₹31,000 crore were identified for financing mainly through green bond proceeds.
Why are 30-Year Green Bonds Attracting Demand?
Long-term green bonds are particularly attractive to insurance companies and pension funds. These institutions require long-duration assets to match their long-term liabilities.
Green bonds also receive infrastructure classification, which can improve their attractiveness for institutional investors. The April 2026 30-year issue attracted strong demand from insurers.

Types of Sustainable Finance Instruments
| Instrument | Primary Objective | Use of Proceeds |
|---|---|---|
| Green Bonds | Environmental benefits | Specific green projects |
| Social Bonds | Social benefits | Specific social projects |
| Sustainability Bonds | Green + social benefits | Green and social projects |
| Sustainability-Linked Bonds | Sustainability targets | General purposes; terms linked to performance |
The key difference is that green bonds ring-fence proceeds for eligible environmental projects, while sustainability-linked bonds link financial terms to broader sustainability targets.
